It may not be a tadpole trike, but it is a recumbent and for now I am using it as part of my “rehab” after total knee joint replacement. It is said that pedaling is one of the very best things one can do for recovering from total knee joint replacement. However, just getting on and off of it is a bit challenging … getting my leg up and over the frame … more so than pedaling it. I am managing it though. Once I have myself straddling the frame I am “in like Flint”. That being said, in order to pedal I need to place my heel of my foot on the pedal so that I am moving my knee thru a smaller circle. I am slowly inching my foot backwards on the pedal as I spend time pedaling, but I only have to move it a short distance before I start “feeling” the discomfort it brings on.
The recumbent stationary bike in the rehab facility where I go is set up with the crank arms quite short and I can spin them easily … even at 100 rpm cadence. I usually only ride my tadpole trike at about 60 rpm. I really need the crankarm shorteners, but alas, my wife says no as she doesn’t want me to spend the money right now. So I am improvising by placing my heel on the pedal. Of course, when I get the other knee joint replaced in two weeks without the crankarm shorteners I will have to place both heels on the pedals. BTW, one might think that pedaling with one foot properly placed with the ball of the foot on the pedal while the other foot has the heel on the pedal would be awkward and weird, but actually it is not a problem at all. It feels rather normal and natural to me. Of course, I would much prefer to pedal with both of my feet positioned normally.
Hmmm, maybe I can sell something to get the money to buy the crankarm shorteners. They would be the “cat’s meow”. (For those who don’t understand that term here is a definition/explanation: “The cat’s meow” is an expression referring to something that is considered outstanding.”) I am not a fan of pedaling with my heels, but a guy’s gotta do what a guy’s gotta do.
Yep, you are looking at the cat’s meow!
While others … KEEP ON TRIKIN’ … I just want to … KEEP ON PEDALIN’ … until I can join you. 🙂
Now here is something I can identify with as I have spent a lot of hours thru the winter doing this very thing.
I would venture to say that probably several of you have seen this video before, but for those who have not I think you will find it interesting. Most tadpole trikes come with some model of Schwalbe tires installed from the factory. There is a reason for that. Schwalbe makes some of the very best bicycle tires in the entirety of the world. Without further ado here is the video:
Yet one more of these videos showing how bicycle components are made. This time it is aluminum wheels. Most of our trikes come with aluminum wheels so let’s take a look at how they are made.
As some of you know I recently underwent total knee joint replacement. That, of course, means that I haven’t been doing any riding. Naturally I really miss it and am anxious to resume riding ASAP. My doctor had told me I ‘might’ be able to ride by 3 weeks post surgery. It has been 2 and a half weeks thus far. Well, I decided to try it. After all I rode the recumbent exercise bike in outpatient rehab last Friday and did ok with that. So this afternoon I decided to give it a go. My wife had gone to work so there was no one here to try to stop me. 🙂 I got my trike out and got it all ready to ride (lights turned on and safety flags in place). My main concern was getting back up out of the seat as I expected that to be problematic. It turned out that should have been the least of my concerns. Sitting down onto the seat was more challenging than I thought it would be, but I made it ok. It was a bit challenging to get my recovering leg into position and my foot resting properly on the pedal, but again I accomplished it and was “ready to go”. As things turned out what I expected to probably be the easiest part of all this turned out to be the most difficult … pedaling. I took off rolling down the driveway toward the street and as I made my first revolution of the crankset and started bringing my new knee joint back toward me I quickly discovered that it caused excruciating pain.
(No, this is not a picture of my knee.)
Normally with the heel slings I use I am able to lift my feet off of the pedals easily and quickly, but with my bum leg I could not do so. The pain just continued. Finally I got my foot off of the pedal and because of all the pain and weakness in the knee joint area I could not hold my foot up off of the ground like I normally can so my shoe made contact with the ground as the trike was still rolling (I did not want to stop in the middle of the street).
That resulted in more pain and I nearly experienced “leg suck“. I somehow managed to avoid that and made it over to the opposite side of the street by the curb where I sat for a few minutes trying to recover. Not knowing how I was going to do trying to get up out of the seat I was concerned that I might have to sit there until I can flag down some help from a passerby. Fortunately when I made the attempt to get up out of the seat I found it to be extremely easy. Upon getting up I started walking my trike back over across the street and up the driveway. I put my trike away and called it quits … realizing that I am not ready for “prime time”. I think the seat vs. pedal height position comes into play here. I think I could do much better pedaling in a traditional riding position such as I had when I rode the recumbent exercise bike in rehab last Friday. It looks like I am going to have to get the 2 wheel recumbent bike out to ride for now as the riding position is quite similar to the exercise bike in rehab. Although it hurt like crazy it probably did me good stretching in bending like that. The outside of my knee joint has healed up nicely and looks pretty good, but it is another story internally. The knee joint remains inflamed, tight, stiff and very sore. It is still generating a lot of heat. And to think that in 3 and a half weeks I am going to have the other knee joint replaced. I don’t think I will be doing much trike riding until next Spring.
(No, this is not a picture of me. That is my trike in the background though. The picture is of a friend who walked the local trails for many many years until he had to give it up recently for health reasons.)
At least now I will hopefully be able to walk on the trails thru the winter months. That is something I haven’t been able to do for many many years and I really miss it. Anyway, as loud as I must have yelled today I figured you might have heard me. 🙂 For those of you who can …
KEEP ON TRIKIN’
and I will join you when I can
The gearing we have on our trikes is a most signifcant thing. Some trikes only have one gear, some have 3, 5, 8, 12, 14, 21, 24, 27, 30, 81, 90 or some other number which is obtained by means of a multiple speed internal hub in addition to the derailleur system. Of course, for a trike with only one gear there is not much involved in figuring out the “gear inches”. What are gear inches, you ask? Actually it is not all that simple to answer definitively. There are variables which complicate things. One such variable which seldom is discussed or taken into consideration is the length of the crankarms. Usually it is just the various sprocket sizes (number of teeth) and drive tire diameter and circumference measurements that are used in the calculation. According to Wikipedia the definition of gear inches is: “the diameter in inches of the drive wheel of a penny-farthing bicycle with equivalent gearing.”
The lower the low number is the lower the gearing is which means one can more easily climb hills. The higher the high number is the higher the gearing which means a faster top speed is obtainable. So the ideal gear inches would be very low to very high. On a derailleur system the rear derailleur is only capable of handling so much of a range. I have an article on this subject HERE. The only way I know of to get around this limiting factor is by employing internal hubs in addition to the derailleur/multiple sprocket system. The internal hubs can be in the rear wheel hub or in the crankset or both. One can greatly increase the gear inch range by using these internal hubs. You can lower the low number and raise the high number. Here are examples of internal drives:
3 speed Sturmey Archer rear hub 2 speed Patterson Drive in crankset
For those who want to figure it all out for themselves here are some formulas to use:
Gear-Inches = Chain Ring Teeth X Tire Diameter Divided by Rear Cassette Sprocket Teeth
Distance traveled per Crank Revolution = Chain Ring Teeth X Tire Circumference Divided by Rear Cassette Sprocket Teeth
And lastly … MPH at 60 RPM = 0.0568182 X Distance per Crank Revolution
I don’t know about others, but I find it interesting watching these videos which show how various things are made. I tried to find a video about bicycle inner tubes, but the only one I found is motorcycle inner tubes. But hey, there isn’t much difference other than size. Here is the video:
Bicycle Chain Bowl
Chain is a key component of most bicycles and tricycles. Without it we aren’t going anywhere. Did you ever take a good close look at a bicycle chain? Most riders just take the chain for granted not paying much attention to it. There just might be more to one than you ever realized. Here is a video showing how bicycle chain is made.
Talk about FAT trikes is what this posting is about. I am not going to say much however. I will let another Steve speak on the subject. Trike Hobo, Steve Greene, of Trike Asylum blog fame discusses aspects of the ICE Full Fat recumbent tricycle, and also fat trikes in general. I can’t speak from any experience as I don’t have a FAT trike nor have I ever ridden one or been around any. Trike Hobo has an ICE FAT trike and gained personal experience and knowledge so without further ado here he is:
If you have never experienced a bicycle wheel being out of true you are most fortunate. Actually it is fairly common for wheels to get out of true. Here is a video showing a brand new wheel which is badly out of true.
I will state upfront if you are not mechanically inclined and savvy don’t attempt to true a wheel yourself as you can make it much worse than it already is. That being said it really is not complicated if you understand the basics involved. A wheel can run out of true in roundness and/or in side to side movement. Although ideally it is best to use a truing stand and remove a wheel from a bike/trike and remove the tire and inner tube so that all you have is the wheel itself the procedure can be done with everything intact on the bike/trike.
This video below does a pretty good job explaining and illustrating it.
I don’t own a truing stand although I have always thought it would be nice to have one. I have made temporary ones in times past which worked sufficiently. However, I almost always true wheels on the bike/trike. One can either find something on the bike/trike to use to “gauge” the trueness or make something to use to gauge the trueness. I oftentimes have simply used my finger or thumb alongside the rim. One must be careful not to overtighten spokes attempting to pull the rim over to one side as you might end up pulling it out of round. If the rim needs to move very far one should always be sure to loosen the spokes on the opposite side and not just tighten the spokes pulling the rim over. That will help eliminate pulling the rim out of round.
In order to tighten (or loosen) a spoke you will need a spoke wrench. There are lots of different types. Most are just one size, but some have multiple sizes in one wrench. Unless you work on wheels that have different size spokes I would suggest using a spoke wrench which is just one size. Be sure to get the size that fits your spokes. I use one like this and really like it.
As I said, there are lots of different types. Here are just a few of the ones available:
As to truing stands one can buy one for less than $50
Or pay more than $500 for one:
Or anywhere in between. You can even get very precision using dial indicators:
Some folks seem to get quite confused with the direction threaded parts need to turn to tighten or loosen. Spokes are always standard … righty tighty and lefty loosey. You just have to remember which way to view the spoke and spoke nut (called nipples). That is not difficult. The nipple simply screws down onto the spoke so you view it accordingly. To tighten the nipple it turns clockwise down onto the spoke. To loosen it turns counterclockwise. Although it is certainly nice to have a wheel turn perfectly true most of us don’t really need such precision.
Lastly this video although a bit lengthy brings out some good helpful information and tips:
Keeping your wheels properly aligned will help you to …
KEEP ON TRIKIN’
We may not have actually seen any in person, but many of us have seen them in pictures and videos online. I am talking about LED light poles or whips as I have heard them called. There is no denying that after dark these things are highly visible and can be rather beautiful as well. Some are fiber optic with the light showing thru out the pole. Some are a bit more traditional with individual lights up and down the pole. Some have blinking/flashing light in various patterns.
I haven’t found them to be the easiest item to locate online. All too often when searching for them for bicycles the search results show those that are for motor vehicles with 12 volt systems. I read where one person used a 9 volt battery to power his. Here is a picture of it:
Many people make their own buying the various components online.
As I said, I have had a difficult time finding much of anything as far as sources to buy these LED pole lights. Here are a few although the Arizona Whips are pretty much designed for 12 volt vehicle use as are many of them I found. They can be adapted to a bike/trike, but one still needs a battery (power source) sufficient to operate them. LEDs are a pretty low current draw so I don’t know how long the 9 volt battery would last. Also the Arizona Whips are not cheap … $150 according to what I read.
made in China fiber optic (would be my choice) $28.50 each with a minimum purchase of two
FAT is where it’s at for some folks. I am sure they are fun to ride, especially off road which, of course, is mostly what they are designed for. I will have to admit if money was not an issue I would probably have one in addition to my current tadpole trike.
Here is a low cost FAT trike made in China. I don’t know anything about the overall quality of it. As has been discussed on this blog previously buying a trike from overseas from a source unestablished as being reliable and providing great customer service would be a major concern for me. That being said, if the buyer is mechanically inclined most of the various components are pretty much standard bicycle parts and so they can be replaced. The frame being made of steel is fairly easily repair weldable by a qualified weldor should it fail. And it can always be reinforced if needed. So for me personally I would not be all that concerned about purchasing one of these. I am capable of doing all the mechanical work and the welding if the need arises. My biggest concern is not so much with the trike itself as it is dealing with the unknown … sending my hard earned money and not having the assurance I will receive my trike. I am not trying to say anything bad about the company as I know nothing about them. But I do know that there have been problems in the past with buying such products from China. In short, people have been ripped off. Well, anyway … on with the information available about this FAT trike.
$1,460.93 includes shipping ($950 for trike & $510.93 for shipping) Estimated Delivery Time they say is 11-19 days … which is very reasonable.What I don’t find reasonable is the shipping charge. Trident trikes only charge $125 and their trikes come from Taiwan.
* 26 inch X 4 inch FAT tires * steel frame * 24 speed * mechanical disc brakes on all 3 wheels * comes with neck rest, front chainring guard,
Available color: red, orange, black, blue, sliver and green
It has direct steering which I applaud. It lacks fenders which is quite typical. And finding fenders to fit a FAT tire trike is challenging, if not impossible. The rear disc brake is actuated by friction lever so it could be used for parking to keep the trike from rolling or as a drag brake on descents. One needs to be careful of that however, as the rear wheel can lock up and contribute to loosing control.
The tires are Chinese, of course, so probably are not the quality of some others such as VEE tires. But, hey, for $950 for the entire trike … once they are shot put better quality tires on it.
As you can see in the picture below the only thing that folds is the boom. That being the case this trike is still pretty bulky as far as fitting it into some vehicles and other small spaces. I also see a cable which appears to be unattached at one end and laying on the ground so I don’t know what that is about. Apparently it has to be removed from wherever it goes in order to fold the boom. That’s not desirable.
I am sure that all the components are inferior off brand ones, but I am pretty sure they work and would suffice for most of us. Again, they could all be upgraded to better quality components when the time comes.
The shifting levers can be seen although not close up enough to make out much of anything. I tried cropping and enlarging the image, but I still could not make out much.
There are alternatives such as the Trident Terrain FAT trike. It also folds (better than the Chinese FAT trike). It lists for $1399 plus $125 shipping (total of $1524). That price is for a 20 inch wheel trike. For only $100 more ($1624) you can get it in 26 inch wheels.
Utah Trikes sells the SunSeeker Fat Tad CXS trike which they produce starting at $1899 plus $299 shipping (total of $2198). That is about a $737 difference and I think is about the next cheapest FAT trike available. It features rear coil-over suspension and integrated front suspension. It too comes with Chinese tires.
So if you are wanting a FAT trike they can be had for less than $8000 like the one ICE sells … or even $4559 for an Azub FAT trike . (One could buy a very nice used car for that kind of money.) Yep, I would buy one if money were not an issue. Alas, I will just have to continue to …
KEEP ON TRIKIN’
on my non-FAT trike and be content. 🙂
Honestly I am most thankful I have what I have.
Workstands are a subject matter which has been discussed previously on this blog. One can buy them or make their own. Some of the most popular ones are made of PVC piping and fittings. Some of them are made of metal. Wood is also popular. Here is a video showing how one person made his workstand out of wood.
As some of you know I am going to have knee joint replacement surgery later this month followed by a second surgery for the other knee joint replacement in November. I am sharing this with you, the readers of this blog, so you will know what is going on. Not knowing how I will be doing as far as whether or not I feel up to writing new articles for posting on this blog it is possible I may not have any new articles for awhile. I hope that isn’t the case, but in case it is I want you to know what is going on. At the time of my writing this I have articles written and scheduled ahead thru October of this year. Again, I assume I will be able to write some more new articles and keep posting them ahead and no one would be the wiser as to what is going on.
Uncle Art (arthritis) is no friend of mine and not welcome in my home.
I am not looking forward to the surgery and rehab, but if it is as successful as most are I reckon it will be worth it. My knees have gotten much worse as time has gone along and it has greatly effected my riding. I can no longer ride as far or as fast or as long as I used to and it has greatly effected my motivation and enjoyment of riding. Right now I need all the help I can get to …
KEEP ON TRIKIN’
I am certainly hoping I can get back to the way it used to be … riding faster, longer and farther and truly enjoying it.

I know nothing of this company or this trike so I am in no way personally endorsing them. I am just sharing this to let you know of their existence. I am always leery buying anything from overseas in a far away country as I am quite concerned about getting any needed parts or customer service. This is not to say that this company would not respond quickly to customers should they need something. I simply have no idea since they are not an established international sales entity with a good and proven track record.
I think we are all very aware that we live in a day of very high technology compared to yesteryear. All kinds of products continue to appear on the scene and some of them are for cyclists. One such product is the Shoka bell. It is far more than just a bell for a bike. It is actually pretty amazing. For what it is worth they call it a bell, but I wouldn’t. It has electronic sounds. It does not sound like a traditional bell … well, maybe it does a little … about like an electronic musical keyboard sounds like various musical instruments. But that’s okay. It has some really neat sounds.
As to the light it is only for others to see you … not for you to see where you are going as it is not that bright nor that kind of light.
One of its features is a an alarm that will alert you if your cycle is messed with. It has a range of 250 meters or 820 feet.
It certainly seems to have impressed a lot of people as the kickstarter campaign is going great … way beyond what they were looking for.
It comes in six different colors.
So if you are a high tech electronic junkie and independently wealthy you might want to look into this gadget. I am only joking about the money end of things. I have no idea what the cost is, but I am pretty sure it is a lot more than my traditional bicycle bells I have bought in the past.🙂
Hopefully you have never had the experience of encountering the big bad teeth of your largest chainring. I am here to tell you that our skin is no match for such an encounter. More than once over the many years of my life I have come out on the losing end. Not only was it painful and sore for some time, but it sometimes got infected and I had to take antibiotics to combat it. If we are fortunate we only get the infamous chainring tattoo.
But if we are not so fortunate we might experience the wrath of those teeth.
Can you say OUCH?
It happens all too easily and without protection we are readily its victim. Even if it doesn’t result in penetrating our skin it can really mess up clothing with a nasty oily dirty stain that is hard to remove. Of course, in warm/hot weather most of us are wearing shorts so there is no clothing covering our legs to help protect us. Even when we do have such clothing on unless it is some very tough material like blue jeans it is no match for those big teeth. Even with blue jeans those teeth can get our attention and cause pain and suffering. And we only have ourselves to sue! Oh my!🙂
CHAINRING GUARDS TO THE RESCUE!
As far as I am concerned they are one of the very best investments we can make for our trikes. I bought one several years ago and it has quite literally saved my hide several times since. On rare occasion I still manage to get a little bit of a tattoo although even those are much lesser than they were without a chainring guard.
My advice to you is don’t wait until you experience those nasty teeth in your flesh. Invest in a chainring guard soon. Don’t procrastinate. It is no fun getting bit by those big teeth. It will help you to …
KEEP ON TRIKIN’
without concern of this calamity. An ounce of prevention is still worth a pound of cure.
