ABSTRACT:
A fully automatic infinitely variable torque converter bicycle transmission makes use of cam followers acting between a driver wheel connected with an input and a follower wheel connected with an output. Torque is varied by varying a radial position of the cam followers relative to the driver wheel and the follower wheel, wherein a return of the cam followers toward an outer radial position is delayed. All force transmitting components of the apparatus are mechanically engaged without relying on friction.
