In a method for detecting a maintenance situation on a two-wheeled vehicle having a motor provided in order to assist forward motion of the two-wheeled vehicle at least at times, a maintenance situation is detected by sensing the position of the two-wheeled vehicle by way of a first sensor variable. Control is then applied to the motor either as a reduction in the applied drive power output, e.g. in the form of the motor speed or torque, or as a complete shutoff or immobilization of the motor.
