Provided is an electric auxiliary drive system for a bicycle having a pedal crankshaft for operation by a rider, an epicyclic gearing mechanism configured to determine a transmission ratio between the pedal crankshaft and an output shaft for transmitting rotation to a rear wheel of the bicycle, an electric assist motor and an electric control motor. The epicyclic gearing mechanism has a ring gear, a sun gear secured for rotation with the output shaft, planet gears between the sun gear and the ring gear, and a planet carrier which is secured for rotation with the pedal crankshaft and supporting the planet gears. The electric assist motor has a rotor drivingly connected to the sun gear to drive the output shaft. The electric control motor is drivingly connected to the ring gear for controlling the transmission ratio between the output shaft and the pedal crankshaft.
