I need to write a mechanical description on a unicycle, and part of the assignment involves developing a diagram of a unicycle pointing out each part on the unicycle.

So if anyone has any technical information on how a unicycle works… please let me know, or direct me to the correct information

Thanks

theres not much to explain, look at a unicycle, I think the rest is obvious.
