Abstract: The present invention relates to an electric propulsion system (1) for a rolling object, comprising a frame (2) with at least one motorized wheel (3), and at least one non-motorized wheel (4), a handlebar (6) and coupling means (5). Coupling means (5) are intended for gripping, orientation and lifting of at least one wheel of the rolling load. The means of orienting the wheel of the rolling object orient the wheel perpendicular to the longitudinal direction (x) of the frame.
