Abstract: A control method comprises at least one detection of activation of the pushing aid. When activation is detected, in the subsequent step a velocity of the electric vehicle and/or a constant starting torque are/is generated by actuation of the electric motor. The generated velocity of the pushing aid as a result of the actuation is dependent on the engaged transmission ratio of the gearshift. In order to adapt the velocity, the control method comprises sensing the current motor rotational speed of the electric motor and sensing the current velocity of the electric bicycle. The engaged transmission ratio is determined as a function of the sensed motor rotational speed and the sensed velocity. The adaptation of the velocity of the electric bicycle occurs in the subsequent step as a result of regulation of the electric motor as a function of the transmission ratio and the maximum velocity, which is not exceeded.
