Can you put a crank that fits a 20" bike on a 26" bike?
The reason I ask is that my mother has knee problems and she has a 3 wheeler she has been riding, but it only hurst on the upstroke while riding, not when pressing down. The three wheeler has standard lengh one piece crank. I was thinking a shorter throw (while harder to peddel) will give her some relief.
Will it work?
