Ultimate Wheel Crank Length

Can anybody tell me a good crank size for an ultimate wheel?

I would think that smaller would be better, as your input would have less effect on the wheel, hopefully reducing wobble, but having a longer length means more control, and many comercial producers make them with long crank lengths.

I am using a 24" rim, and I am making one with plywood disk in the center, so I could make the crank length any size I like.

i put mine 5" from the outer diameter of the rim, and that seems to work well

What is a good crank size for a 26 " rim

150mm

Just to let you know…
considering that you’re making a six spoke ultimate wheel… you can let it have 3 different cranck sizes.

I built my 26er with 125mm and it works pretty well.
