Headkayse One is a game changer for cycling safety because of Enkayse.
Conventional helmets are made from polystyrene. In a large impact polystyrene deforms to provide what’s known as “sacrificial protection”. This is why you have to be careful not to drop your polystyrene helmet in everyday use, and it’s why manufacturers recommend that you replace your helmet after a knock.
Headkayse … pronounced “head case” … hmmm, interesting … is indeed unique. It is scary to think that a brand new conventional helmet can be so easily damaged and rendered considerably less effective in protecting our noggins. It is not only scary, but downright sad and maddening. Who wants to keep buying new helmets quite frequently for fear that our current helmet might not be up to the task of protecting us (even though it might be nearly new itself)?
Enkayse is designed to work differently. It manages the energy of impacts, so it can retain its integrity after more than one impact, large or small. It flexes to the shape of your head for better comfort and security.
Because Enkayse dissipates energy rather than deforming on impact, it also cushions small bumps. Polystyrene can’t do this, since forces which are too weak to deform it are transmitted through. Enkayse provides comfort in protecting from small bumps. This may also have long-term benefits as researchers believe the cumulative effect of small knocks contributes to brain disease over time. Because Enkayse shrugs off little bumps, it means that Headkayse One is durable against the knocks and scrapes that come with everyday use. You can be sure that Headkayse One will stand up to the daily grind. You can view the entire article about this new material HERE.
This is an interesting video (below) demonstrating how conventional helmets are effected by bumps and impacts.
Their website reports that they are 167 % funded in their startup campaign. These helmets don’t come cheap, however, they should greatly outlast a conventional bike helmet which helps offset the price involved.
So if you are a helmet wearer you might consider looking into a “head case” for your noggin. They say they think they will be in production soon (mid 2017). You can pre-order HERE and it should be cheaper than when they start selling them online. They show about $112 plus shipping charges if pre-ordered.
They will be available in 8 different colors. One size fits all. Be safe out there and …

They got the title right …
I came across this video and immediately had to agree with the title … Blinded By The Light. There is definitely a whole bunch of lights there. I assume they own a battery manufacturing company. That top light must be to warn low flying aircraft. 🙂 If I were a car or truck driver coming up behind this I wouldn’t know what to do … probably need to find another route. 🙂 I believe in good lighting, but this is definitely an overkill to the point I would think it would upset others who have to deal with it. I don’t know what their purpose is in having all these lights, but hopefully they don’t ride this around other people at night with these lights turned on .
I won’t even use my bright flashing taillight at nighttime around other people as it would be blinding and offensive to those behind me. Defensive is the goal … not offensive. This next video is of my trike after dark where there is total darkness and no one else around. I have 4 taillights flashing, but one of them is so much brighter than the other three. The other three are plenty bright to be seen quite well at night. The extremely bright one is just too much. As bright as the other 3 taillights are this super bright one prevents the other three from being seen. It is great in the day time, but at night time I would never use it around other people. I would use 2 or 3 of the others and probably only have one taillight flashing and the other(s) turned on steady (no blinking).
Our headlights can also be “too much” Here is my trike with maximum lumens in use. I would not think of riding around like this in the daytime much less at night. I would only use it when by myself and in need of good lighting to see where I am going (at night time, of course.) Too bright of a headlight can quite literally blind those in front of you so that they can’t see some of what is in front of them. This could easily result in an accident and even someone’s death.
And that is only 350 lumen. There are people out there with several thousand lumen lighting. Let’s all be safe but respectful of others. We all want to …
KEEP ON TRIKIN’
Recently I had a Bionx hub motor conversion kit installed on my Catrike Trail. In doing so I had to give up my super comfortable head rest which I made. I have neck issues so I need to use a neck/head rest when I ride. The reason I could not continue using my head rest is because it was in the way of plugging the cable into the front of the battery. So I purchased an ICE neck rest which mounts out of the way. Now ICE boasts that their newly designed neck rest is the most comfortable neck rest on the market. As far as I am concerned it is just like all the rest of the factory manufactured neck rests I have tried … very lacking and not very comfortable. So I went to work to redesign it. What I came up with was far more comfortable than theirs yet it still looked pretty like it did originally. Still it was not to my satisfaction nor my needs. So I went to work to totally remake it. It didn’t take me more than 20 minutes and now I have a very comfortable head rest again. It is not quite as comfortable as what I had previously but only because it is a bit smaller in size. And the good news is I didn’t do anything to change what ICE made. In 5 minutes I could put the neckrest back to the way it came from ICE (not that I would want to). I just don’t understand why the trike industry doesn’t offer comfortable neck rests. It is not that hard to make one that is comfortable. Like I said it took me about 20 minutes. I replaced ICE’s strap with elastic and put a piece of foam sandwiched in between it. Then I put a large piece of foam on the front side of the elastic. The large piece of foam has the front side of it cut concave to sort of cradle the head and neck. Here is what I came up with. I just used the cover off of my old head rest even though it is too big.
For those who are interested here are some pictures showing the construction of my new head rest. (I am calling it a head rest rather than a neck rest because I have raised it up higher to where the back of my head rests on it. It is far more comfortable now against my head than it was against my neck.)
In the next picture I have duct tape temporarily holding the foam in place while the Gorilla Glue sets up. The foam is glued to the elastic.
In the next picture which is a top view looking down you can see the concave curvature I cut into the foam to cradle my head and make the head rest more comfortable to use.
And here is what the original ICE neck rest looks like. I really don’t like the metal rods on the sides as they are located right where the head makes contact with them. And that is not very comfortable as I quickly found out when I tried riding using it. It is really dumb … more of their infamous “inspired cycle engineering”.
Now with this new head rest I should be able to ride in comfort meaning I can …
ENJOY THE RIDE!
You might want to take a look at this video if you think your bike lock is secure. And then there is the cordless battery powered right angle grinders with a cutting disk on it which can cut thru most metal easily and quickly.
Are whilte lights legal on the rear of a trike? I will make this short and to the point …
Yet we see trikers using them all the time. I guess many just like to spurn the law. And I am amazed that most of them seem to get away with it. I have not yet seen the police pay any attention to it around where I live. That surprises me and, I have to admit, disappoints me. I believe the law should be enforced. I tried a white light on the rear of my trike awhile back. It had plenty of red lights as well as you can see in the video below. It really stood out, but I didn’t leave it on my trike as I didn’t want to be in violation of the law.
The reason it is against the law is simple enough. It is confusing to others. In short, they don’t know whether you are coming or going and that is because white lights belong on the front of a vehicle. Most people who see a white light on a vehicle just assume, and rightfully so, that they are looking at the front of the vehicle. After all, that is where the law requires white lights to be. So if you are one of those who insist on having white lights on the rear of your trike you better hope you don’t get involved in a bad accident. Someone might come along and try to twist your head around 180 degrees thinking it is facing the wrong direction. LOL Seriously, I know having a white light on the rear of a trike can be eye catching, but it really is illegal … to the best of my knowledge in all 50 states in the U.S. I would recommend a high intensity red light. They are extremely visible and they are legal. I am talking about daytime use. Riding at night one should not use these extremely bright lights as they are too much and can cause problems for others as they are simply blinding. In the daytime though they work great.
BE SEEN, BE SAFE!!!
There are many bike locks already available and, of course, some are far better than others. In trying to secure our trikes we could do as the person did with this bicycle shown above or we could use just one lock … a FoldyLock. Yep, a rather unique product has come along called the FoldyLock. As many products have started out it used KickStarter which was successful for them and now their product is on the market and available. It is not cheap, but it does seem to be quite secure.
What is Foldylock?
Foldylock is a premium folding Bike lock that easily unfolds to a 90 cm (Approx. 35.5 inches) sturdy lock. When folded it is easily carried in its designated case, mounted on your bike frame , or in rider’s back pack. The case can be mounted to a bike frame using the bottle holder fixing screws or with two specially designed straps. The case has a rattle free mechanism to prevent your lock from shaking while riding.
Foldylock will retail at 95 USD.
The plastic storage case comes in red, green or creme.
Certainly there are several other very good bicycle locks on the market and I am not trying to promote this one over any other. I am simply reporting this one to to you as I came across it recently and thought it worthwhile to share with you.
I have used a 1 watt Planet Bike headlight for many years now. I almost always use it on flash mode as I almost always ride in the daytime and rarely at nighttime. At only 1 watt it is amazingly bright. This is due to the excellent optics employed. It is not a great light for nighttime use, but for for daytime with the flash mode it is superb. It operates on two AA batteries and they last an amazingly long time … like around 20 hours or more. I usually use rechargeable batteries in it which are super economical to use. I recently had a problem with my light as it would shut itself off almost immediately after turning it on flash mode. I just assumed it’s time had come after giving me many years of faithful service. I ordered another headlight to replace it. Meanwhile I removed this one from my trike and brought it inside the house. I started messing around with it and determined that the problem was a simple one and one I could fix. The battery contacts just needed cleaning. Now it is working great again. Here is a video of it I just took inside the house. It shows it on flash mode. Now I ask ya … would this get your attention?
It has always worked fine for me and many people have commented that they saw my headlight flashing from a long distance. It is also quite visible from the side also which is an added plus as many lights are not very visible from off to the side.
Here is my current headlight and taillight setup on flash mode. This obviously is in daylight which is mostly when I ride.
I like the idea of others seeing me while I am out there and am a firm believer of the importance of good lighting front and back as well as highly visible safety flags.
I have also experimented around with taillights and although I really liked what is shown in this next video I opted not to keep it because white light showing on the back of a vehicle is illegal.
As can be seen in the next video I now have a very bright red taillight which is so bright I would not dare use it at night time as it would be blinding to others. It is so much brighter than my other taillights that it makes them look dim when, in fact, they are also plenty bright, especially at night.
Here is my most recent taillight configuration/ Again, I would not use the 150 lumen taillight in full brightness mode at night time if I were out riding around other people. It is way too bright to use around others.
The concept of being able to …
KEEP ON TRIKIN’
appeals to me. How about you?
The Niterider Saber 35 taillight is among the available offerings nowadays. I can’t say much for the mounting strap they use, but the price is right … $16.99 with free shipping on EBAY. And it is BRIGHT! The 35 stands for 35 lumens. With a built in lithium battery it requires recharging using a USB cable plugged into a standard 5 volt USB outlet whether it be a computer or a power adapter (transformer).
LED lights are everywhere these days and that’s good as they are a superior light, economical, bright and long lasting. That being said, not all lights are created equal when it comes to the power usage and battery life. This video tells what to expect as far as how long the battery charge lasts in each of its modes.
I have written articles about taillights before. There are lots of taillights available nowadays … far more than there were when I bought my taillights. At the time I bought one of the very best taillights available … the .5 (half) watt Planet Bike SuperFlash. I paid about $25 each for them at a local bike shop several years ago. The best price I can find on them at this time is $23.75 with free shipping at ModernBike.com. They are not as bright as this Niterrider light, but still I do highly recommend the Planet Bike SuperFlash taillights as they are sufficiently bright and very economical to operate. (I tried to find the lumen rating of the SuperFlash taillight, but didn’t have any success. If you happen to know what it is please comment and let me as well as others know.) The triple AAA batteries last a long time in them. I use rechargeable batteries in mine most of the time. Just carry extra batteries along with you and you don’t have to worry about being left in the dark. With the Niterider taillight it has a built in lithium battery which requires recharging from a 5 volt USB outlet. That is not very practical when you are out riding. And the Niterider taillight doesn’t last nearly as long per charge as the Planet Bike light. On the most economical mode it only lasts 12 hours whereas the Planet Bike lights I have last about 40 plus hours on its most economical flash mode. (BTW, the newer version of the Planet Bike SuperFlash lights supposedly last more than 100 hours on flash mode and is visible up to one mile. I have the older version.) So on flash mode the Niterider light would last long enough for one or two long daily rides, but you would have to recharge it each day or two if you used it long each day. That doesn’t appeal to me.
If you park your trike somewhere near a 120 volt electrical outlet you could use a power adapter outlet to plug a USB cable into to charge the light on the trike. Of course, the light is easy enough to remove from its mount to take to a place to charge it. Anyway, I like the brightness and the price. I just don’t like the mounting strap nor the short battery power.
Here is a look at the Planet Bike SuperFlash taillight. It has a far superior mounting system than the Niterider taillight.
One factor with all taillights and headlights to consider is the built in lenses as they can make a big difference in how well the light performs and can be seen. The pattern of the light as far as spreading out and being visible from the side vs. straight behind. The Planet Bike taillights have superior lenses which really make the “measely” .5 watts perform as well as lights which are far more powerful. That appeals to me since the battery life is so great with these lights. Planet Bike also offers a 1 watt version of this light. They are slightly brighter, but they also require more battery power and therefore don’t last as long as the .5 watt model does. Personally I don’t think there is enough noticeable difference in brightness between the two to justify the sacrifice in battery life. Also the one watt model has a “white-clear” plastic cover instead of red which I personally don’t care for. I don’t think it is nearly as noticeable as the red plastic. Actually much to my amazement I just found the one watt model available thru Ebay for less than the .5 watt model. It is only $19.94 with free shipping.
I just read that Planet Bike has a USB rechargeable version of the .5 watt SuperFlash taillight. It also stated the brightness of the newer USB rechargeable is not as good as the older original lights like I have. The newer light only produces 3 lumens which is extremely poor. Fortunately they do still offer the model which is powered by two AAA batteries.
Here is an interesting video showing how well the Planet Bike Superflash work even when up against a far more powerful light being used for comparison. Remember, we are only talking about .5 watts here.
Another factor is whether or not the taillight offers much side visibility. Some lights offer very little or none at all. The Planet Bike SuperFlash is superb in side visibility. There is a video by a customer review on Amazon which demonstrates how good the side visibility is.
I will say this … if you are after high visibility in daylight there are taillights which are superior to either of these. I have written articles about taillights previously.
Of course, I also highly recommend the use of effective highly visible safety flags in addition to the lights. I have written articles about this subject before. Many times I have had people comment to me that they saw my flags before they saw my flashing lights … from any direction. And, of course, side visibility is going to be very limited if you only have lights. Good safety flags can be seen from the sides and can make a huge difference in whether others see you or not.
Right along with safety flags of high visibility is wearing high visibility clothing.
I started out writing this article with the intent of it being just about the NiteRider Saber 35 taillight, but I ended up drifting over into writing about the Planet Bike SuperFlash taillights. I guess it is because I have been so pleased with mine. I love the long battery life which is somewhat rare with bike lights. I have seen other brands which have very poor battery life. Their brightness only lasts for a very short while in comparison.
I just found what looks to be identical to the Planet Bike SuperFlash taillight on EBAY for only $10.87. It doesn’t have Planet Bike shown on it however, so my guess is that it is an illegal copy (knockoff) probably made in China. If that is what it is I would caution you that it may look like the real McCoy, but may be lacking in quality … especially the lenses I spoke of. If that is the case, then it would not be as bright nor as visible. Also the battery life may be lesser. Then again, it may be very good quality. I would be leery of it myself.
Lastly here is another video of the Niterider Saber 35 taillight.
In all honesty, if I were in the market for taillights today I am pretty certain that neither of these choices would be my pick. There are just so many lights available nowadays and several are extremely bright. Riding at nighttime in darkness I would be quite content with what I have now. Riding in the daytime which is what I do I would prefer one of the brighter taillights that are available. But for now I will continue on using my Planet Bike SuperFlash taillights as they still work fine and have served me well.
What do you call a bicycle bell that doesn’t look like a bell? That’s probably a loaded question, but let’s go with “Oi” since that is what I am writing about. I looked up the word Oi to see what, if any, is the meaning … “interjection. used to express surprise, pain, grief, worry, etc.” Well, I guess ringing a bicycle bell is expressing surprise. 🙂
I like these! They definitely don’t look like a traditional bicycle bell, yet they do sound much like one.
Here is a more technical video about this new product:
Yep, the Knog Oi Bell … It gets my vote. I just hope they don’t ring when hitting bumps like the conventional bike bells do. That’s why I have removed mine and gave up on them. I don’t like “dinging” as I ride along … not unless I instigate it. 🙂
As to the use of bike bells I have noticed that most of them are barely audible as bicyclists come up behind me. Hmmm, I wonder how this one will do. I hope I am surprised.
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
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.
Water … don’t leave home without it!!! We can live without food for a fair length of time, but water is a different story. I don’t know how long a person can survive without water and the answer doesn’t seem to be easily found in an online search. It seems to be controversial. Some say 3 days and others say as long as 12 days. I am sure it depends upon the individual person and the circumstances and environment. Any thinking responsible person will carry water along with them when they go out for a trike ride. Most use some type of water bottle while a smaller number use some sort of “bladder”. I personally have always used water bottles although several years ago I stopped using the plastic type and went with stainless steel Thermos brand water bottles which I love.
Regardless of what type of water bottle we use we need some sort of a holder for them to carry them on our trikes. Over the years I have bought and tried several different water bottle holders. Most of them have been made of metal, usually aluminum. And most of them have eventually broken as the metal just doesn’t hold up. I finally tried some plastic ones and love them. They have lasted for years already and have shown no sign of failing. And so I can and do only recommend the plastic type like I have. The ones pictured below are the type I have. There are other plastic types, but of the ones I have seen and tried (in the store by placing my water bottle in them) I can’t recommend them. I think these are the best of all I have seen.
I have seen other plastic and carbon fiber holders, but I can’t comment on any of them. All I can say is I am well satisfied with the ones I have. I took a water bottle into the store with me to see how the various water bottle holders fit and held my stainless steel Thermos water bottle. These plastic ones I got fit and worked the best. The carbon fiber ones are, of course, extremely expensive and as far as I am concerned there isn’t that much difference in their weight vs. these plastic ones.
Here are pictures of the two I have …
There are water bottle holders which are adjustable so that they will snugly hold various size (diameter) bottles. Personally I don’t think I would put much faith in them holding up. I would be very suspicious of the adjustment mechanism lasting as I think it would be a weak point and likely break or fail.
Speaking of failing … one trike rider recently reported that he rides thru the winter in bitter cold temperatures. He said that the plastic holders will shatter in the sub zero weather so he has to use metal holders. For me, I think I would be more concerned about myself shattering going out in that kind of weather. 🙂
There are also holders which strap the bottle in securely. They work okay, but it is not likely that you could readily and easily get a bottle out of it while riding along.
I use an elastic wristband around my stainless steel bottle to hold it securely in the vertical mounted holder on my seat back so it can’t “pop out” hitting a bump. It is still easy to remove from the holder if I want to do so while riding. Of course, I use the water bottle located on top of the boom as my main source until I empty it. I might add that it rides okay in that holder. So far it has never popped out of it hitting a bump.
I mentioned the stainless steel water bottles I use made by Thermos. You can see one of them in the picture above. I have written about all this before. Again, not all stainless steel water bottles are created equal, especially if you like having ice cold water with you. I have used other stainless and aluminum water bottles and they did not do well at all keeping ice from melting quickly. The Thermos brand bottles will do so for 2 to 3 days although I think they lose their ability to keep ice that long as they age. Mine will only keep ice now for 1 to 2 days. That is still quite good when compared to most other water bottles. The insulated plastic water bottles are a joke as far as their ability to keep ice from melting. I had 3 of them. They barely performed any better than the plain ol’ plastic water bottles. They did good to last 2 to 3 hours before the ice was melted.
I also have a pile of broken aluminum water bottle holders. Don’t ask me why I am holding onto them. Hmmmm, what is scrap aluminum selling for nowadays? Many years ago I would have repair welded them, but alas, I no longer have the welding equipment to do it.
If you are looking for good quality water bottle holders I highly recommend the ones I use. Most LBS stock them and you can, of course, order them online. They come in various colors (white, black, blue, red, and yellow). Sometimes you can even find them in a color which matches your trike. I didn’t find any green so I opted for the white. Besides, white doesn’t absorb heat like darker colors. Every little bit helps when it comes to helping the water to remain cold.
Stay well hydrated so you can …

Convenience … that is what this is all about. Having some of the things we use most often right at our side within easy reach. Well, you can have it thanks to Steve Sussman at FinerRecliner. He offers them for Catrike trikes at this time. Here is one on a Villager …
Here is what Steve says about this product he sells:
This is a great way to keep snacks, camera, phone, gloves and other bring-alongs right at your fingertips, accessible while you ride…you don’t even need to get up!
The side mount kit accepts just about any brand handlebar bag. And it’s adjustable so you can set the bag height, fore-to-aft location and distance from the seat to suit you.
The kit’s “L” tube is also a great place to mount a beverage bottle.
We include the Topeak bottle bracket mount with each kit. And then
you can choose the cage that will work best for you.
The kit includes a 130mm mtb stem, “L” tube of 6061 thin wall
aluminum, end caps and the Topeak bottle cage mount.
Side Mount Kit for Catrikes – “L” tube, mtb stem, Topeak bottle cage mount………………………………………$53.00
For those with a Catrike who are interested in this note that the bag is very exposed to all kinds of crud coming off of the front tire as it is in a direct path of whatever is being thrown off of the tire. Even with fenders I think it would get crud on it. Never the less, I am sure this would be very handy for many riders. I just wanted to point this out so that others would be aware of it.
There you have it. So if you have a hankerin’ for one or two of these (one on each side) they are available. Now you know. 🙂
Hey, if it will help you to … KEEP ON TRIKIN’ … I am all for it.
Do you use a bicycle computer? If so, is it accurate (or akwert as one of my teachers used to pronounce the word)? Getting a computer set accurately can be a bit challenging unless you know what you are doing. Some people settle for their computers to be inaccurate often times not realizing how far off they are and how many extra miles they are showing than they really rode or miles they are failing to show that were ridden.
There are different ways to go about setting a bike computer so it will be accurate. I will confess that I personally have only used one of them. I am happy to report that my computer is about as close as is humanly possible in getting it set accurately.
So let’s get into this. Each bicycle computer should come with instructions which have a ‘chart’ showing the numbers used for various wheel sizes. That often will only get you in the ball park however, and “fine tuning” is required from there. Our local trail system has accurate mile markers (actually every 1/4 of a mile) so I use those to set my bike computer. The tires used will effect things as well. A lower profile (outside diameter) tire will be different than a higher profile tire. Tire inflation will also make a difference so it is best to have the tires inflated to whatever pressure you normally use when making any computer setting adjustment. Even rider weight effects the setting. Depending upon how far off the current setting is the amount of change in the number setting may only be “1” or if it is off quite a bit it may be considerably more. If your mileage shown is under you need to increase the number used in the setting. If your mileage shown is over you need to decrease the number used in the setting.
It is best to check your accuracy over a longer distance … like 5 miles rather than only 1 mile. And once you find that magical number write it down for safe keeping. And if you switch to other tires and the number is different write that tire and number down. It sure makes it a lot easier when you switch between tires.
Here are some instructions on how to set your computer using the measured mile method:
1.0 (the measured mile)
Cyclometer Reading x Old Setting = New Setting
For example: If you set your 26×2.1 wheel size to: 2091 and rode the measured mile and came up short, maybe your computer read .95 miles, then you’d do:
1.0 (the measured mile)
0.95 (what your computer read) x 2091 (old setting) = 2201 (new setting)
If you computer read too long, maybe 1.05, you’d still do the same formula and your setting would be:
1.0 (the measured mile)
1.05 (what your computer read) x 2091 (old setting) = 1991 (new setting)

Okay, change your bike computer setting to this:
HERE is a very handy calculator to determine the number you need to enter if you have the computer reading for a measured mile. The calculator is located at the very bottom of this webpage.
As I stated early on there are various methods of determining the number needed to set up a bike computer wheel size so it records accurately.
HERE is Sheldon Brown’s charts on this subject of computer setting for wheel size. And here is a video showing how this is done.
And HERE is another online chart.
HERE is an online calculator for determining the wheel size setting.
Here is a video showing how to use a tape measure to determine the outside circumference of a bike tire and use that number to set the computer wheel size. This is sometimes referred to as the Roll Out method.
Lastly HERE is the Google search results for this subject. There is lots of helpful information online about this.
And hopefully the following will make things very easy, quick and handy for those of you who use any of these 20 inch tires. These are the magical numbers I have recorded for myself when I have ran various Schwalbe tires.
Marathon (1.5 width) 1425
Marathon Plus (1.75 width) 1561
I have ran a couple of others, but don’t have the number recorded for them. I can’t guarantee that these numbers will work for you but I think they would be close. Like I said, there are various factors which determine what number is needed for each of us … our weight, tire pressure and weight hauling/loading on the trike … may mean your number will be different from mine. It is really not Mission Impossible so hopefully you can get your computer set accurately and from then on just …
KEEP ON TRIKIN’
Before leaving this subject of bike computers I want to touch on the magnets that attach to the spokes. My bike computer came with the type on the left in the image below …
which works, of course, but a friend of mine was throwing out one of his as he replaces his bike computer from time to time (the more expensive ones like he buys don’t seem to last). Anyway, I took it to use in place of my magnet and have found it to be better as it doesn’t get bumper around nearly as easily and seems to be less sensitive as far as it’s position. I rarely have had any issues with it, but I did with the original one that came with my computer.
