The Ultimate Wheel
We decided to spray paint the tire yellow (and the wooden disk purple; sorry no camera = no pictures) The spray paint was still a bit sticky, so there was a lot of friction. How much friction is there usually? I was also wearing hospital scrubs, which may also be a big factor. Zero friction is best, so the wheel doesn't slow down in case one's leg rubs against the tire or wheel. Some people spray the tire sidewall or rim (which ever sticks out more) with something that provides lower friction than the tire or rim by itself. However, low friction of the tire sidewall or rim is not required, since it is quite possible (though more difficult) to ride an ultimate wheel without the legs rubbing the tire sidewall or rim. I read that it is easier if the pedals are very close to the disk. But mine are so close, that my feet, usually my heel, hit the tire as i pedal. I placed the pedals as if there were 5 inch cranks (125mm). Is this normal? Or am i standing on the pedals wrong? Usually, the pedals are placed as close to the plane of the wheel as possible to reduce the so called Q factor. However, it is also possible to simply remove a wheel from a standard unicycle and ride it as an ultimate wheel. This will place the legs further from the wheel, so for that reason alone, the legs rubbing the tire sidewall or rim would be less likely. However, the larger Q factor may cause more "leg rubbing". Pedals set at 125mm from the center of the disk should work just fine. Sincerely, Ken Fuchs |

The Ultimate Wheel
Greetings
In message "The Ultimate Wheel", DasDingus wrote... Well, i finally built my ultimate wheel, with the help of my friends. I tried riding it for an hour, and got some progress. I have a few questions though. How much easier is it with a larger wheel? I have a 20" so is there more wobbling with a smaller wheel? It is much harder with a smaller wheeler. I recommend at least 24, possibly 26. You have much less control with smaller wheels (unless you are a child).

It worked fine for me, but it is easier if you get the 'inserts from unicycle.com' (http://tinyurl.com/l2u7) If you're using a wheel larger than 24" I recomend you lighten it a little by cutting some holes in the plywood (eg. in the shape of really big spokes) Good luck Morten -- Borges - High impact cerabellum workout ------------------------------------------------------------------------ Borges's Profile: http://www.unicyclist.com/profile/925 View this thread: http://www.unicyclist.com/thread/25098 |
