Abstract
A vehicle operable with human muscle power and/or motor power, e.g., an electric bicycle, includes: a crank drive through which a rider torque generated by a rider is introduced; an electrical drive system that can additionally apply a driving torque; and a control unit configured to shut off the electrical drive system when the rider torque is not present. The control unit encompasses a monitoring device which ensures that when the rider torque falls below a predetermined value, the electrical drive system continues to be operated for a specified time span, the duration of the time span being variable as a function of a pedaling frequency.
