Abstract: The invention relates to a propulsion system (1) for a pedal vehicle. The propulsion system (1) comprises a power unit (1) allowing the power originating from a bottom-bracket axle (2) to be combined with the power from two motors (40, 50), a first deformable transmission element (23) allowing the transmission of power to the rear wheel (73) and a casing assembly (19) enclosing particularly the first deformable transmission element (23) and the power unit (1), with the exception of part of the bottom-bracket axle (2).
Abstract: A method of assisted differential transmission for electric bicycle as well as the powertrain associated to this method, comprising two motors articulated around of a differential system comprising a ring gear having an inner surface and an element cooperating with this inner surface, the periphery of said element containing, at all times, the geometric center of the ring gear.

Abstract: A powertrain for a pedal vehicle includes a crank axle and an output sprocket rotating around a first rotation axis. The coupling between the crank axle and the output sprocket goes through an epicyclic gear system that includes a ring gear, a planet carrier, and a sun gear (13) which rotate around a second rotation axis that is spatially offset from the first rotation axis.
