  • Patent number: 12637172
    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).
    Type: Grant

  • Patent number: 11383791
    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.
