The invention relates to an electrically operated drive mechanism which is used, preferably as a propelling drive (13) for a vehicle (12), in particular a bicycle. Said drive mechanism has electric motors (4, 5) driven by accumulators (7, 8) each associated with the two wheels (1, 2). Said electric motors deliver a propulsion force in relation to the wheel speed in different power stages, with differential effect. |
