A control method for controlling an electric motor of an electric bicycle in dependence on an applied transmission ratio of a gear shift includes detecting a pedaling torque of the bicycle rider and detecting the applied transmission ratio of the gear shift. In addition, the control method controls the electric motor for the drive of the electric bicycle in dependence on the detected pedaling torque and the detected transmission ratio in order to generate a torque of the electric motor. The bicycle rider is thus supported by the electric motor while driving the electric bicycle in dependence on the applied transmission ratio.
