Abstract

A shiftable bicycle transmission (30) is automatically shifted by automatically sensing output power torque of the transmission (30), automatically converting sensed output power torque to transmission shifting motion, and automatically shifting the shiftable transmission (30) with that transmission shifting motion. A shiftable bicycle (10) driving power transmission has a transmission shifting element (47, 49), a bicycle output power torque sensor (51), and an output power torque-to-transmission shifting motion converter (1, 2, 3) having an output power torque input coupled to that output power torque sensor (51) and having a transmission shifting motion output. Such transmission shifting element (47, 49) is coupled to the transmission shifting motion output of that converter.
