What kind of speed can you attain on one of those? I have one with a 26" tire (mountain-bike size), because I've pretty tall, but I still haven't quite got the hang of riding it.
By the way: My recumbent bike has even smaller tires (20") but it is way faster. The size of the tires is not the limiting factor in unicycle speed --- it's the fact that you have to keep balance and input power using the same system.
Right, which is why my speed tends to very briefly approach terminal velocity.
I have a fixed-gear mountain bike with 700c x 42mm ("really big") tires, and that doesn't really affect speed much either. The wheels very clearly have a sort of flywheel effect, though: once I'm moving, they hold a lot of momentum. (It's excellent for commuting in snow, BTW.)
