Abstract (en)
[origin: WO2021185613A1] The invention relates to a removable electric propulsion system (1) for a rolling object, the propulsion system (1) comprising a chassis (2) provided with at least one wheel (3) driven by an electric machine (10), and at least one non-driven wheel (4), and means for coupling (5) the propulsion system (1) to the rolling object. In addition, the coupling means (5) comprise means for gripping and lifting at least one wheel of the rolling object. Furthermore, the propulsion system (1) comprises a seating device with a seat (51) and a backrest (50) and this seating device is foldable between a deployed position enabling a user to sit and a folded position. The invention also relates to a method for deploying/folding the seating device of the electric propulsion system (1).
