    Friction Drive Bicycle -- Required Torque

    Hi, I am working on a project regarding the friction drive on bicycles. I would like to design an assembly which has to be compact enough, and has to be able to produce torque that will move the bicycle from a stationary position, but as it turns out with my calculations torque required is...
