An electric auxiliary drive for bicycles includes an electric motor having a stator which is connected to a bicycle frame. A rotor is connected to a rotatable part of a bottom bracket of a bicycle on a left-hand side in a direction of travel. The rotor has a magnet. A control device adjusts the power of the electric motor with a control circuit arrangement. A torque sensor is connected to the control circuit arrangement. The rotor is arranged in a co-rotating housing which is connected to a pedal crank and which is arranged on a bottom bracket shaft in an interlocking manner. The stator is arranged in a housing connected to the bicycle frame and secured against rotation.
