Yes, but some prefer longer cranks and/or ones w/ more Q-factor.
(how far the pedals come out from center)
For Muni, shorter cranks will make it faster, harder to roll over bumps, a bit less control at slow to moderate speeds, less wheel wobble at high speeds, pedal strikes on rocks less likely, and a bit harder to ride up or maintain a controllable speed down steep hills (provided you can maintain a decent pace, ups may be easier for you). If you have brakes, some of these could change.
I am learning to ride on a (borrowed) 24" LX Torker. I will need to get a unicycle for myself eventually. Here is my question:
The Torker seems to work fine. What advantage do the much more expensive unicycles have? The KH and Nimbus both look pretty and are probably sturdier. What difference would I notice just riding around?
The Torker LX is fine for just riding around; the only drawback is that it doesn’t have a very comfortable seat. It’s not as sturdy as the Nimbus or KH (due to the square taper cranks), but it’s fine if you’re not going to be jumping around on it.
