Abstract
A vehicle, particularly a bicycle, including a crank drive that is to be actuated by muscular force and that is disconnectably drive-connected to at least one driven wheel, and also including an electrical auxiliary drive for assisting the crank drive. The vehicle can be driven solely by the auxiliary drive when the drive connection between the crank drive and the wheel is disconnected. In addition, a control device for the auxiliary drive is preferably connected to a sensor which detects the crank rotational speed.
