Abstract
An electric auxiliary drive system for a bicycle having a pedal crankshaft, an epicyclic gearing mechanism, an assist motor for driving an output shaft, and a control motor for controlling, through the epicyclic gearing mechanism, a transmission ratio between the pedal crankshaft and the output shaft is provided. A first one-way clutch operatively connected to the control motor is configured for blocking a rotation of a rotatable member of the epicyclic gearing mechanism in a forward direction of rotation while allowing the rotation of the rotatable member of the epicyclic gearing mechanism in a reverse direction of rotation. A second one-way clutch is configured for drivingly connecting the assist motor to the output shaft when the assist motor is switched on, and for disengaging the assist motor from the output shaft when the assist motor is switched off but the output shaft continues rotation in the forward direction.
