Coker Comments and Questions

The weather just started to turn nice here in Indiana, so I went on a 6 mile
ride on my Coker. I averaged between 9-10 miles/hour, but I had to stop at
the 4 mile mark to recover from “penis numbness”.

I’m concerned that if I go on longer rides, I’ll do some damage. Any
thoughts?

I converted my saddle to an air saddle with an innertube. It’s pretty
comfortable, but when I try to go faster than 10 MPH it gets bouncy. Any
ideas on that?

Thanks!

P.S.
I’m getting better at mounting. I went the whole ride w/ freemounts. (I
stopped once for traffic, once for a break, and once when I fell down and
skinned by hand and knee. I’ll be shopping for knee and wrist protection)

sounds like you have too much air in your air seat.

are you using the original foam from the seat? use the foam along with the airtube (which really doesn’t have much air in it at all, in my case)

Try throwing some cornstarch in your shorts before your ride, or applying a product called Vaseline Creamy (looks like Nivea cold cream, found at Walmart in the skin cream section)

This will solve chaffing issues, and maybe it’ll solve the numbness as a side effect?

You can buy rail adapters to tilt the seat forward which may help as well, but I like to start with the cheapest solution first (most times)

Re: Coker Comments and Questions

I don’t think you’ll do any damage. Just get off for a couple minutes when you get numb, then get back on.

I have almost exactly the same situation numbness wise (I’m on a KH saddle). About 1/2 hour into the ride I get numb; I get off for about 90 seconds, and get back on. After the first 1/2 hour, I get numb about every 20 minutes, so I repeat the 90second break again roughly every 20 minutes.

I think this is typical. I think better riders go longer, but still have the same basic problem.

I’ve a Coker distance riding friend, BigWheelTex, (he’s riding a two day 180+ mile ride this weekend) who really likes the rail adapter he got for his KH equiped Coker. He tilts the seat way up in the front so his weight is more on his buttocks. Claims it substantially improves his butt/crotch endurance.

Numbness is a sign of loss of blood circulation.

Short term this is of no consequence.

Long term regular numbness will cause damage from cell death due to lack of blood flow and build up of by products in the cells, which are being starved. How serious this can be over time I am not aware of. But it is a known fact that racing cyclists have problems due to saddle damage on their ‘underneath’ be it from bruising or numbness caused by the loss of blood circulation.

So be aware!

I think someone should design a more chair like seat for long distance unicycling, which will provide a good degree of support for the large fleshy areas rather than the small narrow section between them. Perhaps you could adapt a large bike seat? Would that work?

Boy, I must be pretty lucky…I can’t seem to picture any time I’ve ever gone numb.

Re: Coker Comments and Questions

Maybe less air. Also you might have the seat a bit high, you need it slightly lower for the fatter seat.

There’s also something about learning to sit on the saddle so that it doesn’t hurt. After a while you’ll get so you can ride for hours without a break.

As far as the bounciness goes, that’s pedalling technique. Concentrate on spinning your feet in perfect circles, when you get better technique, you will no longer be bouncy. With good technique, I can go about 11 mph on my 700c with 125 mm cranks. Crank length has a lot to do wtih it too.

Stand up on the pedals every so often and give yourself a stretch. I usually take a walk every few miles, whether I need it or not. Bike shorts help, but they feel funny.

they look it as well! but so does a unicycle so I don’t suppose it really matters all that much

I’ve found the trick is to do something befor you go numb–such as standing up on the peddles every five or ten minutes, even for a few strokes. If you wait till you’re totally numb, the numbness will return quickly (at least for me) and you’ll probably have to dismount for the feeling to return.

Coming from road cycling–which I still do–I don’t find cycling shorts weird at all. You can get stylish trunks with bike liners, but they rarely have as many pannels as top grade road shorts, so I go with the later owing to their thickness where it counts (I’m on a KH seat with rail-adaptors).

I rode a Giraffe in a parade for an hour and a half once. It broke

one of my nerves and I couldn’t lift my right foot up (at the ankle)

for 6 months. I had to have 3 MRIs and 2 X-Rays and

physical therapy but it came back eventually. I tripped over my

foot a lot though because it just dangled there

.

Dude! . . . . are you serious?
What exactly happened, so I can avoid it?

/been having trouble with my ankles lately when riding

Ouch. Riding a giraffe in a parade is one of those situations where you don’t have a lot of options about getting on and off. That’s why I don’t like to ride mine in parades. I prefer my big wheel.

It’s when you ride for a long time without dismounts and with little or no shifting around in the seat that you risk the pinching off of vital fluids or nerves. I wonder if KcTheAcy really broke a nerve or just killed it by leaving it pinched for too long. Same difference I guess.

I have experienced some severe numbness (and painful urination) in my early days of riding, on a rock-hard Schwinn seat. But I haven’t experienced anything like what happened to me during that first year in the many years since.

So after you’ve got the best possible seat, the right shorts, the right seat height, etc., I think it’s still important to not sit in the same position on the seat for too long. I “adjust myself” around occasionally, shifting a little forward, a little back, or otherwise moving the pressure points around.

Good advice on the air seat. It wasn’t clear from your post if the numbness happened with the air seat or before. But yes, air seats should have very low pressure in them. What you want to avoid is having the high point in the center. The ultimate seats have a high part on each side, and are lower or softer in the center. Re-arrange your innertube if necessary.

Seat height: yes, make sure the height doesn’t have you reaching too far. This is probably not your problem, because if you’re reaching too far it usually means you’re bobbing side to side as you pedal, so you likely won’t pinch off your fluids.

Make sure you’re not sitting on your penis.

Okay, make sure you’ve got yourself “arranged” comfortably. Wear cycling shorts. If you’re wearing something else, you are more than likely sitting on one or more seams, which create nasty pressure points.

Get a handlebar. I have one on my Coker now and can’t imagine doing any long distance riding without one now. For me it’s 16 miles to work and back, so I love my handle. Mine was made by Paul Wyganowski. I didn’t find any of these custom jobs listed on Unicycle.com, but you can use a simpler handle from George Barnes (http://www.unicycle.com/shopping/shopexd.asp?id=576).

I’m attaching a picture of mine. I’m not using it as it was originally intended. I’ve stuck some bar-ends onto what was intended as a front bumper. I like getting into the slight “tuck” I get down there. Someday I’ll get a set designed for me, which will offer a more aerodynamic position, and an actual rack on the back.

I found that switching to excellent cycling shorts eliminated this
problem for me. I won’t ride any significant distance without my
Pearlizumi Microsensor shorts, which have a channel running down the
middle of the chamois to provide relief. There are also less
expensive, but still pricy, shorts with contoured chamois.

So THAT’S what I’ve been feeling in my airseat all this time…:smiley:

Boy, we must be pretty lucky that you didn’t post those attempts at a
picture :slight_smile:

Seriously, the issue of numbness and possible damage has (of course)
been discussed before on rsu. Search for ‘penile’ (which is the
adjective of penis). But there’s a lot of good info in this thread
too.

Re: Coker Comments and Questions

Thanks for all the replies. I forgot to mention that I am using bicycling
shorts with chamous (is that spelled right?). They are about 30 years old,
from my high school days. Perhaps there are better ones available now.

What is a “rail adaptor” ?

I’m looking for a cheap handle. I’m thinking of something that attaches to
the seat post.

a rail adapter basically turns the bottom of your uni seat into the same thing as the bottom of a bike seat…with rails.

This fits into the same type of seat post as a bike…you have a HUGE range of tilt adjustability you could tilt it beyond riding position up or down, and any spot in between
