TerraCycle makes some great products for our trikes. With the ever increasing popularity of electric motorized trikes having a way to mount the battery is crucial. It is not desirable to mount a heavy battery up high on a trike as it raises the trike’s center of gravity considerably and effects the handling and therefore safety of the trike. Keeping the battery mounted down low and out of the way is important. TerraCycle offers some solutions … some specifically made for certain trike and battery brands and others which aremore less generic. Actually as far as I can tell from their webpage they only have kits for Catrike and ICE (rigid rear) and (suspended models) at this time.
They do offer a highly configurable mount so chances are pretty good they can help a guy (or gal) out with their battery mounting problem. When ordering one needs to specify what trike (brand and model) as well as e-motor system and battery they have so TerraCycle can send the correct spacers needed for the specific kits or to help them in getting you a mounting bracket which will work on your trke.
I said that keeping the battery mounted down low is important as far as the trike’s center of gravity. This is quite true, however, the downside of mounting the battery down low is that it is then very vulnerable to getting water, mud, slush and whatever else flung up on it. I presently have my battery down low, but I am seriously considering mounting it up on the rear luggage rack somehow as my battery is getting so messed up for all kinds of stuff being flung up on it. I don’t like that. When I first got my electric motor pedal assist kit I had the battery located in the rear rack and I didn’t have any issues with handling. The battery certainly stayed a whole lot cleaner up there and it was a lot handier to get to it. Some manufacturers of e-motors offer a special rear luggage rack designed to hold their battery. Unfortunately most of these rack mounted batteries are not very powerful so the cruising range they offer is limited.
A larger battery can be mounted on top of a rear luggage rack, but then the luggage rack can’t be used for a trunk bag. Panniers can still be used. I sure will miss my trunk bag if I end up mounting my battery on top of the rear rack.
The battery can also be mounted on the boom. However, that is a lot of weight sitting on the boom and the boom was never intended to carry weight like this so I don’t know how wise it is to do this. I am not saying that it won’t hold it okay. I just don’t know.

Today as I post this is December 25th. It is the day when most of the world pauses to one degree or another to acknowledge the fact that God came to earth in the form of a human Baby on a mission to provide a way for man to be saved from the consequences and penalty of his sin. Man can not save himself although many try. That Baby grew into a Man and completed the mission He was on. Unlike us He lived a perfect life free from sin. This was most important as He was to be the sacrafice offering for sin … the only offering acceptable to a holy God. You can read more about all of this in great detail HERE . Sadly the world (most of mankind) has rejected this salvation God offers to us. Doing so comes at a very high price as our eternal soul is at stake. God offers us this FREE GIFT of His salvation, but for all those who reject it and ignore it they forfeit the opportunity He offers to be forgiven of our sin and we then must pay the penalty and answer to Him in judgement. God is love and He demonstrated His love for all of us by dying a cruel agonizing death in our place. His love is AIMED AT YOUR HEART. He has done all that is needed and all that He can and will for us to be saved from our sin. The choice and decision is ours. Once we breathe our last breath it is too late to choose Him and receive His gift of salvation. Our fate is sealed. So I ask you … if you have never responded to His invitaton … WHAT WILL YOU DO WITH JESUS? Someday your heart will be asking … WHAT WILL JESUS DO WITH ME? The answer to that question can be readily found in His written word … the holy scriptures. God is holy and can not allow sin in His presence. We as sinful people have a problem. Our eternal soul will spend all of eternity either with God (if the sin problem has been taken care of) or apart from God. Being apart from God means spending eternity suffering in anguish in hell fire. God has warned us. We are free morale agents. God created us with the ability to choose to do what we want. We have free will. We are not robots preprogrammed by God to do what He wants us to do. There would not be any expression of God’s love in that. Recognizing and responding to God’s love for us loving Him in return is the ultimate expression of love. It is not a matter of obeying God because we have to. It is all about obeying God because we want to … we want to please Him out of a motivation of our love in return. Yes, God demonstrated His great love for us while we were yet sinners … in the very act of sinning and rebelling against Him … Jesus Christ died for us. Therein is love!
I know there are those who will read this and get upset over it. There will be those who want to tell me it has no place here on a blog about tadpole trikes. But you know … none of that matters. There is not a more important message to communicate to others than this message. In obedience to God I am willling to ruffle a few feathers upsetting some. This timeless message may touch a few hearts and that is what matters. So on this Christmas Day I present the Christmas message. It is not about the many things man does at this time of year … putting up an evergreen tree and decorating it, giving gifts to one another, feasting together as family and friends or any number of the things man does during this holiday. The truth is most everything man does is based on pagaanism practices the Roman Catholic church brought into our culture. And no where in the holy scriptures are we commanded or instructed to observe the birth of Jesus Christ. And He wasn’t born in December anyway. With all of this being true it is important not to “throw the baby out with the bath water” so to speak. This Christmas holdiay does exist in our culture so I for one intend to take advantage of it and proclaim the message of the Cross of Jesus Christ. The reason for the season is truly all about the fact that Jesus did come to earth to provide salvation. He came the first time as a helpless Baby. He will be returning soon … very soon … as the King of kings and Lord of lords. His word tells us that He is coming to pour out His wrath (His anger) on all of those who have rejected Him and the salvation He alone offers. Far better is it to accept and respond to His love now than to be the recipient of His anger later. We are without excuse if we fail to respond to His great love while it is being offered and is available to us. Time is short. Besides none of us know what a day may bring forth. Our last final breath could be seconds away. It is all a most serious matter. The greates gift is not one placed under a tree. The greatest gift in the One Who was placed on a tree. His Name is Jesus. Merry Christmas to all!
Many of you know what all has happened since early last summer when I bought my 350 watt hub motor kit from BionX. At first I loved it even though it topped out at 19 mph instead of the 20 mph they advertise. I did have a problem of the battery not lasting nearly as long as I needed it to, but BionX was good enough to replace the battery with a larger capacity battery free of charge. All was fine for awhile, but then the “pedal assist” mode stopped working and all I had was the hand throttle which was not only a pain to use holding the button on as I rode, but it drained the battery down much quicker than using the pedal assist mode. BionX sent a new replacement motor under warranty, but they sent the wrong motor. This replacement motor lacked the torque (power) the original motor had. It would go 20 mph though which I liked. I complained about the low power, but it pretty much fell on deaf ears thanks to the BionX dealer telling BionX that my unit works properly. I didn’t appreciate that as I know how it worked when I first got it. This dealer didn’t know what he was talking about and wouldn’t listen to me. I talked to both the dealer and BionX about getting a full refund. The dealer said that I would have to pursue that with BionX and BionX said I would have to pursue it with the dealer. After some weeks past I emailed BionX about all of this, but it seemed to fall of deaf ears. I mailed a letter to the CEO/President of BionX explaining everything to him. I asked for his help and told him if BionX continues to ignore me I will have no choice but to contact the Better Business Bureau and file a complaint. BionX never responded back to me so I filed the complaint. BionX had so many days to respond to the BBB about the complaint, but they were silent. Being past the alloted days the BBB contacted BionX again and shortly after I got a phone call from BionX in which I was told BionX wants to resolve this to my satisfaction. I had been saying all along that this replacement motor is not the same motor I had originally, but I was ignored. As far as the dealer was concerned it was the same motor and it worked the way it was suppose to. The phone call from BionX finally got the truth out of them as they admitted that they had sent out the wrong motor … one which was not as powerful. So they sent out what was suppose to be the correct motor and I took my trike back to the dealer for the motors to be exchanged. While at the dealer I took the trike for a test ride and came back very disappointed. It still didn’t have the power of my original motor and the top speed was only 17 mph instead of 20 mph claimed by BionX. A few weeks past by and nothing changed so I emailed BionX requesting a full refund. I received an email reply today saying that the refund is being processed. Once I have the refund in hand and they have their hub motor kit back I will look into getting a different brand as I am sold on having a hub motor with torque sensing pedal assist and manual hand throttle. I will keep you informed of how that goes. Hopefully it will be better than my experience has been with BionX. It is a shame as I really liked the BionX unit. I will miss their display console and handlebar mounted control. They are probably the best of all those in use for e-bikes. I know many people have had no complaints with their BionX systems. I don’t know why I have had all these problems. I sure would have liked for it to work out otherwise. With my expensive but very nice BionX system I was hoping to …
KEEP ON TRIKIN’
update Jan. 16, 2018: I took the BionX system back to the dealer and got the full refund. Now I am looking to see what I will try next. I am definitely sold on having the electric pedal assist system. I loved having it and am anxious to replace it. BTW, getting a different system can be done for half the cost (or even less) of the BionX unit and it will involve a larger size (power) hub motor and a larger capacity battery.
Canopies are an item which can be a real blessing to have. They can help shield us from the hot sun and even offer some protection from rain. I have a friend who slips a large plastic bag over his to make it totally waterproof if he has to deal with rain while out riding. Some people make their own canopies. My friend made his and another friend made his. There are only a few manufacturers of canopies that I know of. Prices range considerably as do the design and build. I have written about CANOPIES before. One manufacturer I know of (Ed Miller) offers several options on his canopies. The other canopy manufacturer I have written about before (Andy Vardik) no longer makes them. There are a very few companies around who offer them. One of them is Recumbent RagTops. There is also VelTop which offers canopies for recumbent bikes and trikes. This posting is featuring Recumbent RagTops as I have never written about them before.
I think it is safe to say that this design would catch a lot of air especially with the rear flap down over the mesh “window” so no air can flow thru and out the back. Also it is domed quite high which makes the canopy much higher than most others I have seen. Personally I would want the canopy much lower down than this … just a few inches over the top of my head. I have no idea how it handles winds. Also I wonder about visibility of traffic lights as one approaches them
Here is a video with a review of this canopy which addresses all of this and more …
Speaking of homemade canopies, I came across this video which I really like so I am sharing it here …
Here is a rather unique canopy which may or may not appeal to you. Since I like having the air on me it has no appeal to me whatsoever. But if it “flicks you Bic” it is available. I had a very hard time finding the price on the website. However, I finally found it in their catalog. Here is what they show:
“Our popular M4 canopy can be used for many HPV applications for a simple wind and rain fairing. The 8 lb acrylic tinted (or clear) canopy is adaptable but you must make your own attachment and support system. $400 plus $150 shipping.”
In other words all they supply is a hunk of plastic. You are on your own when it comes to mounting it. That has no appeal to me. If I buy a product for my trike I expect it to come with whatever is needed to use it on my trike. I am not at all impressed with what I see on this website. They don’t even have the canopy mounted on the trike they are using to display their product. Instead the guy sitting on the trike is holding the canopy in place with his hands. It is not even centered on the trike when you look at the front view. That seems very unprofessional to me.
There it is folks. Just selling a piece of plastic that one has to figure out how to mount. Nope, I ‘ll pass. I would expect most people would. They need to offer mounting hardware if they are going to sell this product. I wouldn’t know where to begin to come up with what would be needed nor would I want to. How about you?
Anyone who has followed my writings over the years knows that I personally use and have recommended JSRL Design Heel Slings. I have always liked them and still do, however, there is a new product out which I recently bought and must say I much prefer over the JSRL product. The keyword here is “NEW” as Terratrike had an older product which isn’t nearly as good as their new one. At the time of my writing this I have not been able to fnd the new one online and it appears as though TerraTrike’s website isn’t showing either one of them right now as the page won’t open for the old one and the new one is not yet shown. The new one is considerably more expensive ($55 vs. $40), but it is worth it as it works great. So if you are n the market for these be careful you don’t buy the earlier version as you would probably be very disappointed. We are talking all new and improved here in their latest version.
The big difference between these two products (JSRL vs TerraTrike) is the JSRL heel slings use a steel cable which works, but it sags down making it harder to use. The TT product has a steel flat bar bent like a U with Velcro straps attached which adjust for shoe size. It fits snugly and doesn’t sag so it is easier to get in and out of. I only installed them today and rode about 20 miles with them trying to stay dry as I dealt with Tropical Storm Irma’s rain. I fell in love with these TT heel slings right away. There is a world of difference between the two.
I found myself bending the flat bar almost immediately as it was bent in too far for my liking. It worked as is, but I like it better now that I bent it a little bit. That is one good thing about these heel slings … they can be tweaked to fit the individual’s shoe and riding position on the pedal by bending the flat bar. I am not saying that this is something TT intended the purchaser to do, but it certainly doesn’t do any harm as long as one doesn’t bend the metal back and forth to where the metal becomes fatigued and could weaken and even break off.
I may look into trimming off some of the excess Velcro strap as I am not too wild about it sticking way out beyond what is needed to do the job.
I have written various articles in the past about heel slings, foot retention, pedals and leg suck:
Here is a picture of TT earlier version just so you know what it looks like and can avoid buying it thinking you are getting the most recent one I am recommending here. As you can see there is quite a difference. The first version was rather flimsy, not nearly as practical and was harder to use.
Regardless of what means you choose it is a very good idea to do something to prevent leg suck. It is not something you want to experience. Be safe out there and …
KEEP ON TRIKIN’
This is an update — Many of you know that I purchased a 350 watt hub motor kit from Bionx. Everything was fine at first with the exception of not getting many miles out of the battery. I was truly disappointed in that factor as I found myself having to stop during my daily rides to plug in somewhere and recharge my battery. That was no fun. I wanted to be riding not sitting around waiting on a wee bit of charge to go back into my battery. One hour of charging was then used up in ten minutes or less. I shared my disappointment with the Bionx dealer and they told me to bring my trike in and they would check things out. It is a 2 hour drive to the dealer so I am not crazy about having to drive down there any more than I have to. I went down and they checked everything out saying it is all normal. That being said, Bionx was good enough to send the larger battery free of charge to replace the medium size battery I had purchased which was rated at 65 miles. I was getting about 27 at best. The larger battery is rated at 80 miles. One of my friends has this battery with his 350 watt hub motor. He gets far more miles per charge out of his battery than I was … probably twice or more miles. While waiting on the larger battery to arrive my pedal assist mode quit working. All I had available to use was the hand throttle which uses up the battery even quicker. Again, I had to take my trike back to the Bionx dealer. Bionx determined that the problem was in the hub motor so they sent a replacement under warranty. Once it arrived I, of course, had to make another trip down to the Bionx dealer to get the new motor and the new battery installed. The pedal assist worked again, but now this larger battery didn’t perform as well as the smaller battery. I only got about 22 miles out of it before it was used up. And when charging it it got extremely hot as did the charger. So another trip back to the Bionx dealer was needed. They tested everything out and said that it all checks out okay (normal). They did however, replace the 2 day old battery installation with another battery. This one doesn’t overheat, but it still takes way too long to charge and two out of the three times I have charged it thus far it never showed that it was charged up. The green light never came on. Bionx states that their batteries should charge up in 4 to 5.5 hours, but I have been dealing with batteries that sometimes take as much as 11 hours to charge. As I said, the battery I have now most of the time never shows a green light indicating it is charged. It just remains red. BTW, they state in their manual that it first shows red indicating it needs charging and then when the charging begins it changes to amber and finally to green when it is charged. Well with 3 batteries it has never had an amber light … only red and green. My friend says he has never seen an amber light either. With this new battery and over inflating my tires 5 psi I finally got about 40 miles out of the battery charge. I am happy enough with that, but I sure am not with the matter of charging the battery taking so long and not showing it is charged after such a long time.
I also complained about the hand throttle not working right with this new motor and battery. They test rode it and said it works fine. They don’t know what they are talking about. It has no power when applied. Before when it worked right using the hand throttle was like having JATO assist. The trike really took off. I could shoot across a road getting out of the way of traffic or I could zip up a hill. Now I have to pedal up the hill as the hand throttle does next to nothing. My two friends who have this same setup both have hand throttles that work like mine used to. I could not believe that the dealer claimed that the hand throttle works the way it is supposed to.
So …. I have emailed Bionx and shared with them what is going on. I am hopeful that they will do whatever it takes to get me a system that works right and stays working right. I am not a happy camper at this time. I told them that if they can’t get me a system that works right I want my money back. I am waiting to see what happens. I will let you know.
From what I have seen I think Bionx has a serious problem with quality control. I sure hope they get their act together. I really like their system, but I sure can’t recommend it as things stand now. I mean … I want to …
KEEP ON TRIKIN’
(and not driving back and forth to the Bionx dealer.)
Update – My battery problems seem to be doing much better now. I can ride much further on a charge and the battery seems to be charging normally now. Bionx instructed me to run the battery completely down so that the sensor would refresh and reset itself properly. That seemed to work. Now if they can just get the hand throttle working right I will be a happy camper.
“verdict is in“
Update – As instructed to took my trike back to the dealer (which is about 150 miles round trip) as BionX was supposed to resolve the hand throttle issue. It was a wasted trip as they accomplished nothing and said that there is nothing they can do to get it working like it used to. So I am stuck with an expensive system that doesn’t work right and there doesn’t seem to be anything I can do about it. I am considering requesting my money back. I have no idea what would happen if I were to do that. I have also considered attempting to file some sort of a consumer complaint against BionX which is a Canadian company. I have no idea how to go about that. Needless to say I am not a happy camper and as a result of all of this the jury is in and I give BionX and thumb down. It truly saddens me as for the most part I really like this system. I think they have a serious problem with quality control, but this is to be expected when one is dealing with Chinese made products. Advanced western nations never should have got involved in getting any products made in foreign countries with cheap labor. We should only make our own and thereby benefit our own people.
BIONX HAS PROBLEMS
Got a KMX tadpole trike and want front suspension? Well, here is good news. It is available and simply bolts on. The suspension will fit any recent KMX adult trikes. That’s good news, but there is bad news too as it is very expensive … over $1000. Be aware that it also adds quite a bit of extra width to the trike.
Travel : 52mm (2.05in)
Bike total width will increase by 146mm (5.75in)
Material: Alu 6061-T6 Black Anodized
Weight: 1.25 kg each.
Air shock used : http://www.kindshock.com.cn/en/produc…
No modification required on your KMX. Just remove the brakes & wheels, bolt the new suspension, reinstall the brakes and wheels.
Note: This custom item will only fit on a KMX Trike but it is not a genuine KMX product.
Yeppur, dogs are people too. At least some of them think so and some of us do too. That’s okay. For sure they are part of the family.
Some of us even look like dogs. Did I really say that? I better restate that … sometimes we have dogs that resemble us. Take a look – – –
(In all fairness as far as I know neither of these national leaders own these dogs they are pictured with. Somebody just made up the images in jest. It is probably true of the images below as well.)
And some not quite as well known …
My point is … let’s see … I knew I had a point when I started this. Oh yeah, we are attached to these critters so it is only natural we want to take them along with us when we go out riding our trikes. Now some people pamper their pets to the extreme and only haul their furry friends in a trailer or basket. That is okay for some of the time, but hey … they need exercise too. So there are options available. Some dogs do better than others when it comes to catching on to what they need to do to walk and run alongside of us or perhaps up in front or even behind us. They learn quickly what is expected of them and what they need to do (or not do) to be safe. Other dogs need help and help is available in the way of devices to attach to our trikes which they in turn are attached to. Using these devices they walk and run safely alongside of us out of harms way. Well, they are unless we run them into something. With extra width these devices add to our trikes we need to be careful we don’t do just that. Some dogs even need a special shield alongside of the rear wheel to keep them from getting into it and getting hurt. Anyway, here are a few of the options available:
In my opinion and experience it is best to have a means of both hauling your dog as well as walking and running him … at least if you are riding far enough with him where he needs a break from walking and running. If the dog is small enough he can be hauled in a basket aboard the trike, but a larger dog definitely requires a trailer to accommodate him.
Some people just prefer a trailer anyway regardless of the size of the dog. And, of course, some people have more than one dog so a trailer is pretty much a must to take the dogs along safely and comfortably.
And then there are the MUSHERS … dogs who love to pull
Some dogs are pullers, some dogs need to be pulled and some dogs are pretty much neutral … they just walk or run alongside without pulling or being pulled. It is important to “know your dog” and ensure he is getting his exercise without overdoing it. He may need to ride for awhile and then go at it again. Some dogs may only be good for a mile or so at a time while others can walk and run several miles before needing a rest.
Me with my dog. He was one great dog …
one could not ask for a better dog.
Some dogs are better trained and behaved than others. Some dogs seem to be more easily trained than others. Consequently some dogs do fine without being fastened into a basket or trailer while others definitely need to be “contained”/”restrained”. Keep in mind that in case of a tip over a dog being hauled in a basket is probably more likely to be injured than a dog which is somewhat free to move about some as he can jump out and avoid being injured … or least being less injured than if he would have been restrained in the basket. Unfortunately there are dogs which will jump out if they are not fastened in and that could be very bad especially if you are moving along when they jump. My wife and I had a dog once that jumped out of the window while we were driving down a highway. The only thing that saved him from serious injury is he had his leash fastened and my wife was able to pull him back thru the window before anything happened.
Keep in mind also that carrying a dog in a basket up high off of the ground raises the trike’s center of gravity considerably making it all the easier to tip over.
I have noticed that most dogs enjoy the view as well as the wind in their face. They often tend to move about just to see what there is to see. This can sometimes be a bit challenging for the trike rider as the movement of the dog can effect the handling of the trike.
Please don’t allow your dog to run loose on his own. It is irresponsible. It is dangerous for your dog and for others. Many “accidents” have happened as a result of dogs running loose. It is bad enough when a dog gets injured in these accidents, but it is far worse for innocent people getting injured as a result of the dog owners negligence. I have known friends who have been seriously injured when a loose dog went right in front of them. Sometimes dogs chase after other cyclists which can be very intimidating. And it is against the law to allow a dog to run loose!
And if you are taking your dog along with you please be a responsible and law abiding owner.
Unless you have a special dog who cleans up after himself, be sure you do it. It is the right thing to do.
It is absolutely disgusting to deal with this scenario … dogs owners who do this deserve to have their faces shoved down into this pile of shit.
Yeppur, dogs are people too as far as enjoying tadpole trikes. With our help and with our responsible behavior we can all …
ENJOY THE RIDE!
I am sure most of us who are old as dirt like me remember the generator dynamo light sets we had on our bicycles. They worked, but the amount of light varied according to the speed we rode. They could be very dim or we could ride so fast that we could burn out the bulbs (which I did many times). In short, they lacked good technology to better regulate the power being produced. Yet they did work. We have certainly come a long way when it comes to bicycle lighting. I only mention these old generator dynamo light sets because what I am writing about here is something which looks very much like the generator dynamo of old.
This new generator dynamo very much incorporates modern day technology, but its purpose is not to produce power for lighting. Nope, this unit provides 5 volts of D.C. current for a USB outlet so we can power up all sorts of modern day electronic gadgets to charge them as we ride. I don’t know much about it, but I find it intriguing.
The cost is reduced to about $33. However, the website shows it is “currently out of stock”.

Keep in mind that this product is designed to use on a standard bicycle so using it on a tadpole trike might involve some ingenuity mounting it so it would line up properly and work on a trike wheel. Some trike frames might be more challenging than others. Of course, it could be operated on any one of the three wheels of a trike. I assume that sooner or later it will be back in stock. The website does provide an email service to notify when it is back in stock. I really like the idea of being able to recharge a cell phone or other devices … and doing so while we are riding. It all helps us …
ENJOY THE RIDE
BTW … there are other products out there besides this one:
and there are several others
The old gray mare, she ain’t what she used to be. To be blunt, some of need help for one reason or another. Getting into the seat of a tadpole trike can be challenging enough for some of us, but getting back up out of the seat can be even more challenging. I have good news and bad news. Which do you want first? 🙂 Let’s just go with the bad news and get it out of the way.
“SKY HOOKS” don’t really exist. It is too bad as they would be extremely popular. My first introduction to the imaginary sky hooks was when I was in the Navy. Along with the “mail buoy watch”, “relative bearing grease”, “batteries for the sound-powered phones”, “shore line stretcher“, “a long weight” and several other pranks the sky hooks were a fun thing to play on gullible newbies. Anyway, a sky hook is a device which has a hook on both ends or at least the top end and a closed strap on the bottom end. One end hooks up to someplace up in the sky and the other end is used to hoist or hold something up. If we had two sky hooks it would be the cat’s meow in helping us get up out of our trike seats.
All joking aside let’s get to the good news. There really are devices available to help us get in and out of our seats. Various trike manufacturers offer them for their trikes. Here are some examples:
my favorite is the one pictured below
HERE is what Utah Trikes sells.
HERE is what PowerOnCycling sells for Catrike. (I like these & they are lower cost than most others.)
HERE is TerraTrike’s VersaBars.
HERE is HP Velotechnik’s StandUpAid.
HERE is another product for Catrike:
And HERE is the same product for Catrike from another source.
In order to use these Catrike Stand Up Assist bars as illustrated the vertical handlebars would have to be moved much further forward than I would want them. I like my vertical handlebars out near the ends of the horizontal bars coming off of the steering heads. Moving them forward greatly changes the leverage and control feel.
My experience in attempting to pull back and down when trying to get up is that the trike wants to roll/move (slide) backwards and this makes for a serious problem in trying to use any of these sort of devices. Others have said that these work and they don’t have this problem, but I can’t see how it is possible based on my own personal experience.
My thinking of an ideal means of help in getting up out of the seat is to have the assist bars way up high above one’s head and forward a ways so you pull yourself up rather than having a bar down low where you push yourself up. Also pulling down from above would work much better as far as the trike staying in place and not rolling backwards. Such an overhead bar could be made to telescope in and out so that it isn’t always high in the air. It could telescope out and lock once extended upwards. Of course, it would have to be made pretty strong to be used like this. Hmm, maybe I’m still thinking about those sky hooks. I really think someone needs to get serious and invent the sky hook as it would make all this so simple and work so much better than any of these aids. 🙂
So if you need help getting in and out of your seat you might want to look into one of these aids. They are all we have available for now. I wonder if there is any money in inventing a sky hook. Hey, Enjoy the Ride … and …
KEEP ON TRIKIN’
Those who have been following my writings from the git go probably know that I got my start in this writing articles about tadpole trikes on Steve Greene’s Trike Asylum blog. One of my earliest articles (To Motorize Or Not To Motorize, That Is The Question which was posted on April 5, 2013) was on the subject of motorizing a tadpole trike and I made it pretty clear that I was against it. I made an exception for those who truly needed it Never the less I ruffled some feathers and caught some flak for writing the article. I have to admit that when I wrote it I didn’t know much about the subject of motorizing a trike. I don’t recall whether or not I was even aware of “pedal assist”. Anyway, since that time I have gotten myself a bit more educated about pedal assist. I also finally reached the point I felt I would benefit from having electric motor pedal assist. I have had one on my trike now for awhile so I have experience with using it and feel I am qualified to write about it. I am loving it. Anyway, I am reposting the early article I wrote so you can read it here in this posting. You will find it at the bottom of this article I am now writing. As you read thru it you should be able to pick up that I was thinking that this subject matter is about propulsion by a motor and not pedal assist.
Recently a fellow triker brought up the matter of a tadpole trike being a Human Powered Vehicle (HPV) … that is to say, they are suppose to be. Hey, that is exactly the position I used to hold so I know where he is coming from. We are all familiar with the terms “Pros & Cons” … stating those things in support or favor of and those things which are not if support or favor of. After having a motorized pedal assist trike and riding it quite a lot already I though it would be good to try to write an unbiased opinion and report on the pros and cons of having a pedal assist motor enhancement. Of course, now I speak only of “PEDAL ASSIST”. I like the description … “it’s like having a built in tail wind”. I am still against a motor propelling a trike where the rider is not required to pedal.
I will state the things that come to mind as pros as well as those things which come to mind as cons. I will say upfront that the list will be considerably lop sided as I have been giving thought to this matter and have to say that there is very little I can come up with to put on the cons list while there is a whole lot that comes to mind to place on the pros list. This certainly is not an exhaustive list. As I think of more I will add them to the lists.
1) It makes pedaling easier not requiring nearly as much pressure to be exerted on the pedals. This greatly helps in hill climbing and those with knee joint problems, pain and weakness.
2) The rider can go considerably faster even though they are exerting the same amount of pressure on the pedals and using the same amount of energy as they did previously. For instance, climbing a hill that used to slow me down to 2 to 4 mph I can now ride up at 14-16 mph if I want to.
3) If the rider tires out during a ride the motor assist helps them to get back to wherever they started from or need to get to.
4) If riding has become a chore rather than the fun it once was then pedal assist can make it fun again.
5) It enables a rider to ride at a faster pace so that being able to ride with faster riders is now possible. You still won’t be able to keep up with a lot of the roadies however as they really go. Funny thing is they are allowed on bike trails and some bike trails ban pedal assist bikes and trikes. It is not right.
6) It is a real blessing to have when you need to zip across a busy street when a break in traffic finally comes along. It can propel you across fast and out of any danger.
7) When you need to make good time to get some place faster than you normally could again the motor is such a blessing.
8) Having the ability to accelerate quickly and go fast can be a big help in getting away from a dog or person you might be concerned about as far as your personal safety. Of course, most dogs can run faster than 20 mph.
9) Because you are still pedaling, but pedaling easier you actually get more exercise. You can pedal at a faster cadence which is a very good thing as many of pedal way too slowly anyway. And because it is easier to pedal you can ride longer.
10) Someone who has had problems with hernias and are concerned about overexerting them self and causing serious problems can greatly benefit from having pedal assist.
11) Having electric motor pedal assist does not mean that you have to use it. You can ride with it turned off just like it wasn’t there. And quite honestly most of the time I can’t tell the difference between riding my trike as it came from the factory and riding it now with the motor and battery installed but not turned on.
12) If you have long downhill grades you can set the controls to generate rather than use power and in doing this you recharge the battery. You can also just ride along recharging the battery if you are strong enough to pedal with the resistance involved. Or if you are up to the task even on level ground you can pedal along recharging the battery if you are physically up to it. Please note that the charging rate in this mode is very little so it would take a lot of time and travel to put much of a charge back into the battery.
13) You can play with the minds of the road bike riders by being able to ride their speed and maybe even pass them. Some of them however ride much faster than a motorized pedal assist can go (legally).
14) When riding off road the pedal assist is great to have. It makes such adventure so much easier and enjoyable and even safer as one doesn’t always have the strength to pedal in/over/thru some places.
15) It reduces the stress being placed on the drive system (pedals, crankset, chain & sprockets) as the motor is helping to turn the rear wheel.
16) If you are riding with others and you have to stop or slow down and they keep going having the pedal assist motor makes it much easier to catch back up with them.
17) It is great when riding into a headwind. Other than feeling the wind you can truly say “what wind?”.
1) The motor and battery add weight to the trike. It has added over 20 pounds to my trike and all on the back. That being said, much to my surprise and delight the only time I can tell there is additional weight is when I lift it. When I ride I can’t tell it at all.
2) Being able to go faster is fun, but it also adds a measure of danger and concern that didn’t exist riding slower. You may tend to go into curves faster than you should. If you are not used to handling a trike at higher speeds you could crash.
3) It is expensive to add a motor to a trike and the battery only lasts so long before it needs to be replaced at considerable cost. My conversion kit costs about $2500 and the replacement battery costs about $900 to $1000. There is always the chance that the manufacturer will either go out of business or simply not offer a replacement battery later on if they opt to make some changes in their product offerings.
4) Some trails don’t allow the use of any motors on them. I personally don’t think that this should apply to pedal assist systems and I would hope that trails which say no to them will reconsider and change their position on this.
5) Motorizing a tadpole trike adds to the value making it more of a target for a thief.
6) Motorizing a trike makes it so much fun to ride that your spouse or boyfriend/girlfriend will want to ride it and cut you out of the picture. 😉
April 5, 2013
I am getting into something here which I will state upfront I am very opinionated about. I”M ‘AGIN’ IT! To my way of thinking motorizing any type of human powered vehicle is defeating the whole concept of the thing … exercise. I mean, come on … if you want a motorized open air vehicle buy a motorcycle for crying out loud. I rode them for over 50 years of my life until I finally decided I would give it up for strictly pedaling around. I was also riding a bicycle all those years so I still got some exercise … just not nearly as much as I do now.
I am sure that there are some folks who are not able to pedal to get around … perhaps can’t use their arms and hands to propel a vehicle either and so they may NEED something in the way of a motorized trike. But there are a whole lot of folks out there who are perfectly capable of pedaling who really don’t NEED to go this route.
That being said, I know it has become pretty popular. The man I sold my homemade tadpole trike to told me he planned on motorizing it. There is lots of information out there on the subject. And I am sure riding a motorized tadpole trike is a lot of fun even though it could lead to an added element of danger. And there may be some folks who just need help pedaling up hills as just maybe their bodies can’t deliver what it takes.
Obviously there are two main ways to go … electric motor or gas engine. Those who oppose gas engines because they “pollute” would no doubt only consider the electric motor route. But I AM STILL AGIN IT!
Here are some pictures of various setups:
KMX trike motorized
gas engine motorized trike
solar charging motorized trike
ecospeed motor on boom
And I say to ya’ll …
KEEP ON PEDALIN’
(We all need the exercise!)
By the way, one needs to be aware that there are trails where it is against the rules to ride a motorized bike or trike. Our local trails here in the Fort Wayne, Indiana area do not allow them. Only motorized wheelchairs are permitted. When it comes to “pedal assist” it is not fair to ban them. They are as much as a human powered vehicle as the roadies out there zooming by at 25 plus mph while my top speed is only 20 mph with pedal assist. HERE is a good article on the subject.
It took several years, but I have finally succumbed to the concept of my using electric motor pedal assist. It is a matter of aging I think and finding it a bit more challenging climbing hills. I can still climb them, but oh so slow and if I am riding with others I just watch them ride on away from me as I can’t begin to keep up. So I bit the bullet and got myself some help. Now I can shoot up those hills and don’t have any problem keeping up with my friends should I choose to ride with them.
The electronics are quite sophisticated and pretty well thought out. The reviews of Bionx are extremely favorable. Pretty much everybody say they have the best system going. The company is out of Canada.
They have 3 different size batteries. They are all 48 volts, but their power in amperage varies providing a choice of 50 miles, 65 miles or 80 miles between charges. At least that is their claim. In reality the distance is far less like maybe half. The battery pictured below which fits under their rack is the middle one. The largest battery mounts down low behind the seat alongside of the frame.
Although with this battery mounted up under their rack means the weight is carried up high effecting the trike’s center of gravity and handling it also means that the battery is positioned so that it doesn’t get nearly as messed up from water, mud and other crud being splashed up on it like would happen if it were mounted down lower alongside the frame. Also having it higher makes it much easier to get at to charge it or remove it.
Their controller (shown above) has been upgraded as have their display console.
This display unit (shown below) has replaced the larger combination display controller they had previously.
This next video features an older version of the console and controller which has been replaced with the ones shown above. I offer it here as it still is helpful in understanding some factors of the Bionx system.
The new electronics also offers a Bluetooth connection to their free smartphone app which among other things is a tracking and reporting info of the route, ride and even pulse of the rider. The Bluetooth module sells for $175.
They offer 250, 350 and 500 watt hub motors. I understand that Bionx limits the top speed of 20 mph for all units shipped to the United States to comply with the law.
If your trike has a 20 inch rear wheel you are limited to the 350 watt hub motor as the 500 watt is too large in diameter to be laced into a 20 inch rim. If you have a larger diameter rear wheel such as a 26 inch or 700 the larger 500 watt hub motor is available for them although the larger motor may not be needed. The bike shop dealer told me that unless one lives someplace with a lot of steep hills to climb the 350 is more than enough power to use on a trike.
Having a FAT trike with electric motor pedal assist sounds like a very helpful addition for off road riding. It might require someone skilled at wheel lacing to come up with a wheel laced to a hub motor.
It is my understanding that the batteries can be charged approximately 1000 times. Replacement batteries cost between $900 and $1000 so they ain’t cheap.
The bike shop I am involved with is a Bionx dealer. He told me about the high tech system Bionx has in place making trouble shooting and repair easy for the dealers. They simply plug the unit into a computer with Bionx software installed on it and it connects with Bionx while running diagnostics on the system. The dealer gives permission for Bionx to remotely do various things while connected to your unit over the internet and they can remedy most problems or at least know what is wrong so it can be remedied. With this system the dealers don’t have to learn and know a lot about the Bionx system yet they can take care of the customer.
Here is the Bionx installation video. It shows the older system however.
In closing I want to mention that there are more powerful hub motors made and available which can propel a trike much faster (not legally mind you) and even at 70 years old there is still a part of me that is attracted to riding along at 45 plus mph on my trike, but I am wise enough to know that when you play with fire you are likely to get burnt. I would probably wrap myself around some tree or telephone pole. Nope, I best stick with the 20 mph option. That is plenty fast enough.
With the use of electric motor pedal assist it can help us to …
ENJOY THE RIDE & kEEP ON TRIKIN’
Update (5/3/17) – I now have the Bionx hub motor system installed on my trike and I am loving it. I haven’t been able to ride it much as it has been raining for 3 days straight. I took some pictures of my trike with this unit installed. I remounted the controller from where the bike shop had located it. I like it much better now as I can see it much better and get at it much handier. I probably should paint the blue piece of steel tubing I used to place on my mirror where I mounted the controller. I need to paint it black so it is not so conspicuous. 🙂 Anyway, riding with this motor assist is amazing. For the same effort I used to exert to ride 5-7 mph I can now ride about 14-16 mph. And for the same effort it took to ride 10-12 mph I can now ride 19 mph. The battery has a built in LED taillight which is extremely bright. Above the taillight is a large red reflector. As I said, I haven’t been able to ride it much yet, but hopefully I soon will be. And it surely looks like I will most definitely …
ENJOY THE RIDE!
Who needs fenders? We all do unless we like getting all kinds of ucckkkyyy stuff on us. Even if you ride only when it is dry it is quite likely that you will occasionally get “something” rather unpleasant flung up onto you. If you are going straight most stuff just goes on your arms, but when you are turning it gets flung up on your chest, lap, and legs. Sometimes even when going straight stuff gets flung elsewhere on you. I am always amazed with those who ride without fenders and don’t think they need them. They either live a charmed life or they are not being honest about this matter.
Now if you are riding off road and at a very slow speed or even on pavement at a very slow speed fenders may not be needed, but most of us ride on pavement and fast enough that crud is flying off of our tires. BTW, to my knowledge most FAT tire trikes don’t have fenders available for them at this time.
When it comes to fenders all too often the quality and design is not all that great. Some are downright poor in design while a few are much much better. I personally don’t like the ones that have braces on them. I much prefer the ones which have a strong mounting bracket such as newer Catrike, Greenspeed, HP Velotecknik and ICE offer. I have the older type Catrike fenders and mounting hardware (pictured below) which I don’t care for at all. I paid a lot of money for them and they are junk. They are a problem in more ways than one. The steel rods easily get bent and cause further damage to the fender. Plastic fenders are fairly strong and durable, but they have their limits.
The braces like pictured above which employ the plastic mounts shown are not desirable in my book. A few times I have had the fenders get chunks broken out of them where the braces attach. When that happens I have had to relocate the braces to get to a place where I can reattach them. I have learned something about attaching these braces which helps. The small screw which is used in the plastic part that attaches to the fender should not be allowed to go “thru” the plastic fender as if it does it weakens that area of the fender considerably and is the main cause of those areas breaking out. So now I just tighten the screw until the tip of the screw slightly penetrates the plastic fender enough to hold it. I have not had anymore chunks breaking out since I started doing this.
Most fenders are plastic, but some folks use wooden, steel or carbon fiber fenders.
Chain tubes seem to be somewhat of a controversial issue among tadpole trikers. Some people just don’t like them and remove them. They replace them with a dual idler pulley setup. Some say that using chain tubes slows them up as the chain drags thru them and the friction involved is the culprit causing the slowup. Some just don’t like the appearance of chain tubes. They say they are unattractive. Some say that chain tubes are noisy and they object to having them because of this. I personally don’t buy into most of the objections people raise. If everything is set up correctly I think chain tubes are a great component to employ on a tadpole trike. They keep the chain cleaner while keeping the rider cleaner. They “manage” the chain keeping it from flopping around unnecessarily, keeping it from rubbing on the frame and also keep it in place, especially if the trike is folded.
A few years ago I decided to try eliminating the chain tubes and using a second idler pulley. I ran my trike that way for awhile, but I didn’t care much for it and went back to the original setup. In fact, I even added an additional chain tube on the back side. I personally think the argument about slowing one up is silly just as is the argument about safety flags slowing a trike up and/or making too much noise flapping around. There are always going to be people who think like this and that is ok. They can do what they want. It does bother me however when they try to talk others out of using these things. A good safety flag may very well save your life.
You can see in this picture of a folded Azub trike how well the chain tubes
control the chain keeping it in place and protecting the trike frame.
In managing a chain they keep it from making contact with the trike frame and rubbing the paint off of it. They keep the chain from making contact with the rider’s leg and leaving a “tattoo” on the skin or clothing. They keep the chain in place so it doesn’t get relocated somewhere it doesn’t belong and cause other problems. This also includes the fact that it helps eliminate our having to get our hands all messed up trying to get the chain back where it belongs. Keeping a lot of the chain enclosed eliminates a lot of exposure to external elements which get the chain dirty.
The way I look at it the trike manufacturers know what they are doing and they incorporate the use of chain tubes for very good reasons. Yes, they can be eliminated, but why would you want to? In doing so you are defeating the whole purpose of why they were installed. Not every chain tube installed from the manufacturer is set up properly. I will grant you that. I redid mine so that they sort of “float” and stay in line with where the chain moves to when shifting between the various sprockets. I even heated the chain tube and put a slight bend(curve) in it so it better lines up with the chain. I also flared the ends of the chain tubes so that the chain moves thru the chain tubes better. I don’t notice any drag or noise from the chain tubes and I definitely like my leg and clothing from not making contact with the chain thanks to the chain tubing. Lastly one thing I have observed when it comes to the use of chain tubes is that they can be too long or positioned wrong or held to solidly to where they interfere with the chain moving freely allowing proper shifting onto the sprockets … front or rear. This is all common sense stuff but, hey, it happens and needs to be corrected so that everything works right. (Right along with this I have also seen idler sprocket/pulleys positioned too close to the front derailleur and sprockets which do not allow the needed movement and alignment of the chain to shift properly onto the various sprockets. This can also be the case at the rear derailleur. This is especially true with homemade trikes or trikes where someone has replaced the original chain tubes and made them longer or placed them too far forward or back in the case where they are on the rear of the trike.)
So who needs chain tubes? In my opinion we all do. But, hey, you do whatever you want. Forest Gump had it right and they say you can’t fix it! Did I really say that? Shame on me! Hey, …
KEEP ON TRIKIN’ & ENJOY THE RIDE!
Note: I started out writing this article about an update on the subject of crank arms shorteners, but it more less evolved into another topic so I changed the title accordingly.
It has warmed up a bit recently and all the snow has melted. Between that and rain we have had recently the rivers have risen and flooded over their banks so that some parts of our local bike trails are flooded over and closed. Boo Hoo!! Never the less I have been able to ride my tadpole trike which I thoroughly enjoyed despite the nasty wind chill factor. In order to ride my trike I removed the crank arm shorteners I had installed on my wife’s recumbent bike I am using for rehab and exercise here at home. I installed the crank arm shorteners on my trike. (I was even able to move the pedals one hole further out so that means my new knee joints are improving.) What a difference! I really like them (Yes, both the crank arm shorteners and my new knee joints.) 🙂
However, there is one thing that I noticed using them on my trike that I didn’t notice on the bike. With the crank arm shorteners installed on my trike I need to readjust my boom … lengthen it … as I am not getting the leg extension I need with the pedals relocated. I have not done that yet, but I should. It probably will require adding some more chain. That is the main reason I haven’t tried moving the boom out yet. It is winter out there folks and I am not too crazy about working out in the cold to accomplish this task.
A rear derailleur is supposed to be able to handle about 2 inches of extra chain length as far as movement of the boom. That equates to approximately one inch of boom adjustment. However that figure is based on the boom position at the shortest length the rear derailleur handles to the position of the boom at the longest length it can handle. If the boom is already positioned out quite a ways within that range than most of that 2 inches is already used up. If this is the case then additional chain would need to be added.
One nice option is to employ a Universal Boom Adjust Chain Tensioner designed for the boom of a tadpole trike.
They are not cheap ($155), but they do make it easy to move the boom in and out and automatically maintain the proper chain tension. They are especially nice to accommodate various riders of differing sizes. The chain can be made up long enough to move the boom out for a tall rider and when the boom is shortened for a shorter rider the chain tensioner automatically takes care of the extra chain the rear derailleur would not be able to handle. Obviously there is a lot of extra chain and hardware involved and it might appear a bit unsightly to many (myself included), but they do work. You definitely would not want to run it into a curb or such as it would likely be damaged. TerraCycle (not to be confused with TerraTrike) manufactures these for several different brands of trikes. They can be purchased from some trike dealers and trike manufacturers as well. Catrike sells it for $150, but it is $145 at most of the other sources I have seen including directly from TerraCycle. The Chain Gobbler fits Greenspeed trikes and sells for $149.
Here is a Utah Trikes video on the subject of these chain tensioners …
So this is a very handy and practical option available. Most definitely if you have various size riders riding the same trike this is the way to go. Adding and removing lengths of chain even if you use links which are supposedly quick and easy to remove is a real pain compared to this slick setup. So if you have $150 or so burning a hole in your pocket here is a place to unload that cash and make your life easier. It is always nicer to ride then to “wrench”. And it will even help you and others to …
KEEP ON TRIKIN’
For a very long time now I have wanted to try using crankarms shorteners as they are supposed to help those who have knee joint issues. And it is said that short people should use shorter crankarms. I qualify on both. At my rehab physical therapy sessions I am going thru for knee joint replacement their stationary recumbent exercise bike has the crankarms adjusted to their minimum setting and that setting works great for me. I recently ordered a set of crankarm shorteners so I can pedal normally. With my 165 mm crankarms that came on my trike I have to place the heels of my feet on the pedals in order to pedal it. I tried pedaling my wife’s recumbent bike which I have set up on an indoor trainer out on the enclosed patio at the back of the house, but I couldn’t even pedal it with my heels on the pedals. I think it has 175 mm crankarms. I just am not “there” yet in my recovery. At rehab I can pedal with my feet positioned normally on the pedals. I even cranked it up to 100 rpm cadence a couple of times. So the shorter crankarms really do make a difference. I am really looking forward to having them on my trike.
Here is a video which explains the need and benefit of shorter crankarms.
What I am not looking forward to is winter weather for the next few months. I don’t know how much I will be getting out riding thru the winter. If it gets nasty enough I will no doubt bring my trike back inside the house for the third winter in a row and set it up on the indoor trainer in the living room in front of the large screen TV which is also used as a computer monitor. With access to the internet I can find all sorts of stuff to watch on that big screen in front of me including riding on bike trails. It is almost like being there except I can’t lean in the turns. 🙂
Yep, a set of these just might be your ticket as well.
Shortens cranks by 24, 41, 59 and 76mm. I am pretty certain that I will be using the 59 mm position (next to the shortest) as that will give me about 106 mm crankarms which is close to the setting of the crankarms on the stationary recumbent exercise bike I am pedaling at rehab. The really neat thing about using these is that if and as one improves the pedals can be moved further out. I doubt if I would ever go back all the way to 165 mm though.
HERE is an article I wrote previously about crankarm length.
HERE is the best price I have found on them. I am quite certain that they are going to help me to …
KEEP ON TRIKIN’
As many of you know I am in the slow painful process of recovering from total knee joint replacement. I am 4 weeks post surgery as I type this. All in all I am doing very good. I was walking without a walker in just 2 weeks time. I was driving motor vehicles in 3 weeks time. One thing I have been aware of and have even written about before is the use of shorter crankarms. One of the options to this is crankarm shorteners which bolt onto your existing crankarms. They make really good sense to me as they offer various length settings. With this you can change from one setting to another as needed and as your range of motion improves. And if you ever get back to where you no longer need them you simply uninstall them and go back to your original crankarms.
I am currently going thru rehab therapy and sometimes ride a stationary recumbent exercise bike. The rehab facility has two of these bikes, but I can only ride one of them. I looked at both of them and noticed that the difference is the length of the crankarms. The one I can ride has adjustable crankarms and it is setup with shortest available length. I pedaled it yesterday at 100 rpm for a short time. It felt really good to pedal it. Interestingly the physical therapists told me that very rarely can any knee joint replacement patient ride the other bike.
So anyway I plan on buying a set of crankarm shorteners to help me pedal. Hey, if you have knee joint issues and limited range of motion using shorter crankarms might be “just what the doctor ordered” for you. They are not cheap however. I was surprised and disappointed when I looked them up online. The best price I was able to find was about $115 with shipping thru Amazon. They are a different brand than the ones in this video. (I have noticed that the prices seem to change almost daily. The best deals I have found are usually on Ebay.) I had not yet come across these Ortho Pedals which sell for $89 each or $149 per set. Most of the ones I found were far more expensive … $130 and up. Ortho Pedal’s FAQ. Ortho Pedal’s warranty.
BTW, my second knee joint replacement is scheduled for Nov. 10th … just two weeks away. Oh boy! I am hoping to be burning up the asphalt come next spring. Don’t get in my way! 🙂
Tire liners … do they work? Well …………………………….. yes and no. Once more it all depends. I used to use them and as far as helping prevent externally caused flats, yes they work. However, I and a couple of friends who also used them found that they caused flats internally. Now there are things which can be done to help prevent this from happening. Unfortunately we did not do any of it so we got occasional flats as a result. I would think that there should not have to be any thing done extra such as this for the tire liners to work properly and not cause internal flats. Now that I use the best tire money can buy I no longer use tire liners as I don’t need them. That being said when I first switched to the Schwalbe Marathon Plus tires I installed the tire liners initially as I already had them and had been using them for a few years on all the various tires I had tried previously. I thought it would be a good idea to have the extra measure of protection. Big mistake! I got about three flats over a period of a few years. All were internally caused flats. When I replaced the inner tubes I removed the tire liners. I have not had any flats since.
So my advice is if you are going to use a regular tire prone to getting flats the tire liners are a good thing. If you are going to use them either sand the end of the tire liner where it overlaps itself to remove any sharpness or use duct tape to help protect the inner tube from any sharpness on the end. Personally I would do both … sand the end and use the duct tape.
And be sure the end is rounded as this will help with the edge the inner tube comes in contact with.
Lastly with or without tire liners I highly recommend using talcum powder inside the tire and on the inner tube to reduce rubbing and abrasion which cause ‘internal’ flats. Put the talcum powder inside of the tire after the tire liner is in place.
Definitely there is “abrasion” which occurs when tire liners are used. Take a look at this picture.
You can plainly see the outline of the tire liner on the inner tube. Notice the sharp line of the end of the tire liner where it overlaps itself. Again, using duct tape on the end will greatly reduce this. As to the use of duct tape some say to put it over the end which overlaps. Some say put it on both ends. I see no reason to put it on both ends as it is only that which is in contact with the inner tube which is a concern. I would only put it on the overlap area. Here is one way to do it … wrap it around the top and bottom of the tire liner and then trim the duct tape to the rounded end shape.
I wonder if it would not work better to just place a piece of duct tape over the overlap once the tire liner is in place inside of the tire. That way there would be less thickness at the overlap so that the overlap would not protrude out as far into the inner tube. I see no advantage to having tape on the bottom side of the tire liner since it is not in contact with the inner tube. Also the tape on the overlap would help hold the tire liner in position inside of the tire. The end which overlaps tends to want to drop away from the rest of the tire liner once it is up inside of the tire so I think it would be very helpful to place duct tape over the overlap.
To the best of my knowledge there isn’t all that much difference in quality and protection offered between the various brands of tire liners. I have read that the Kevlar liners should not be used as they don’t work very well. Stick with the plastic type such as Mr. Tuffy, Rhino Dillos, Stop Flats 2, Zefal, and Slime. As you can see in the picture above they are pretty tough.
I think that with the exception of Rhino Dillos all of the tire liners come packaged all rolled up tightly in a small coil/roll. In doing so the inside end is all curled up and presents problems when trying to work with it to install it. So because of this I recommend buying the Rhino Dillos as they are packaged so that this doesn’t happen. They are rolled up in a larger diameter. If you buy one of the other brands it is best to take it out of the packaging and hang it up by the small inside curled end (if it is one rolled from the end) so that it can straighten out for a day or two before installing it.
If it is one rolled from the middle like pictured below then, of course, you should hang it from the end (either end).
Again, my thinking is the worst way of packaging these tire liners is to fold them in half and then roll them up like the red one pictured above. If I were buying any I would steer clear of any packaged like that.
I myself have only used Mr. Tuffy tire liners, which is the originator of tire liners. They are made of made of durable, lightweight polyurethane. They also have what they say is a lighter weight product for those who are weight conscious/concerned. They claim that their liners will not cause tire or tube damage. I take issue with that as I consider causing internal flats as “damage”. Whether the hole is the result of a puncture from the outside or abrasion on the inside it is still damage and has the same consequences … a flat and a destroyed inner tube.
Tire liners come in different widths since tires come in different widths so be sure you get the correct width for the tires you are using. They also come in “XL” for FAT tires.
As to installing tire liners you will find different methods and suggestions ‘out there’.
Some say to remove the tire and inner tube completely off of the rim so you can install the tire liner inside of the tire off of the rim. That is the way I have always done it. Some say to leave the tire and inner tube on the rim and just remove one side of the tire off of the rim so you insert the tire liner between the tire and inner tube. Some say to remove on side of the tire off of the rim and remove the inner tube. Certainly it can be accomplished in any of these ways. It is important, of course, to ensure that there is nothing sharp inside of the tire or rim before installing the tire liner. That is best and easiest accomplished by removing both tire and inner tube off of the rim. It is also important to be sure the tire liner is centered inside of the tire and that the inner tube is installed correctly with no twists or other abnormalities.
Here is what Mr. Tuffy shows as to how to install the tire liners:
I found it interesting that their instructions say to remove any debris found inside of the tire casing before the inner tube is removed. How in the world are you supposed to check inside the tire casing without first removing the inner tube? DUH!
I personally much prefer to take the tires completely off of the rims to install tire liners. Doing them while still on the rim one can not nearly as easily tell where the tire liner is positioned as far as getting it centered in the tire. Of course, no matter how one goes about it there is always the chance that the tire liner will move out of position during final assembly and reinflating the inner tube.
Another good reason for removing the tire completely off of the rim is one can much more easily and thoroughly examine the casing of the tire and do anything needed to ensure the tire is fit and ready to use.
The side of the tire liner that has the extra layer of material bonded to it (it is usually darker color like shown above in the picture) goes outward toward the tire.
I watched several videos on installing tire liners and quite frankly I was not very impressed by any of them. I settled for this one to use here.
Well, like ol’ Forest Gump … that’s all I have to say about that. Tire liners? … Use them if you need them. As for me, I am going to just continue to use the best tire money can buy and not concern myself with flats. My Mr. Tuffy tire liners are hanging up on the garage wall. I will probably never use them again. It is a real joy to just be able to …

and not be concerned about flats. And it is great to get such phenomenal mileage out of the tires as well.
All those round things with teeth around the outside are commonly known as “sprockets”. (Yes, I know for those who insist on being technical … they are cassettes/cogs on the back and chainrings on the front.) These sprockets are several different diameters and this is for a reason. All those different diameters provide a different gear ratio when the chain goes from one to the other. When the chain is on the smallest sprocket in the front and the largest sprocket on the back it is the lowest gear ratio. And when the chain is on the largest sprocket in the front and the smallest sprocket in the back it is the highest gear ratio. Knowing these gear ratios, lowest to highest, helps us to determine the performance capability as well as the hill climbing ability and effort needed. As to the fastest speed we can ride we can only pedal so fast. Once we reach the maximum rpm we are capable of pedaling we reach the maximum speed we can go. The only way we can go any faster is to have a higher gear ratio. And even then we reach the point of “practicalness” as sooner or later we find too much resistance in our pedaling.
There are other contributing and limiting factors involved in determining the gear ratios such as wheel size and tire choices, but I am not addressing any of that here.
HERE is a well written article on the subject of understanding gear ratios.
As you can see in the picture above an oversize sprocket has been installed on this tadpole trike. It looks mighty impressive, but the truth is probably not many of us could pedal it to its potential top speed as we just don’t have what it takes. Most of our trikes come equipped from the manufacturer with a 52 tooth sprocket as the largest. The picture above is real, but the one below is fake … a little photo editing fun I had sometime back.
Mind you there are bikes and trikes with oversize sprockets which have been ridden to accomplish setting new land speed records for human powered vehicles. Usually they have some sort of streamlined bodies on them so they can cut thru the air and not deal with the resistance you and I do with our plain ol’ trikes. Here is a picture of one such vehicle which broke the world record. I haven’t kept up with who currently holds the distinction so this may not be the current record holder.
It takes more than gearing to accomplish such a feat. One must be a very top athlete to reach these speeds with just human power. But you can bet there is not 52 tooth sprocket installed here.
Some of us need help with gear ratios as what we currently have isn’t “getting it”. It can get a bit on the expensive side when one starts changing all the sprockets to accomplish such a change in gear ratios. Obviously the best time to do it is when the original sprockets are wore out and in need of changing. And we can only accomplish that by …
