The present invention relates to a removable electric propulsion system (1) for a rolling object. Propulsion system (1) comprises a frame (2) with a driven wheel (3) and at least one non-driven wheel (4). Among these non-driven wheels (4), one at least is an orientable off-centered wheel. System (1) also comprises means for coupling at least one wheel of the rolling object. System (1) also comprises an automatic directional locking device for locking the rotation about a vertical axis of at least one of the orientable off-centered wheels in a predetermined direction.The invention also relates to a coupled assembly comprising a propulsion system (1) and a rolling object.The invention further relates to a method for directional and automatic locking of at least one orientable off-centered wheel of a propulsion system.
