Hello, I planned to do a friction drive for a Bicycle or a belt drive (if u have any ideas…).
But I stuck on the planning. I want the outrunner running directly on the bicycle wheel. And I want to calculate the max. Speed. Or the ratio. And so on.
Motor is the SK3 6374 149kv on 10s (36-42v) And a 26" bicycle. And a VESC
Like in the picture…
