Zusammenfassung:	The invention relates to a removable electric propulsion system (1) for coupling to a roller body. The propulsion system (1) comprises: a chassis (2) provided with at least one wheel (3) driven by a motor and at least one non-driven wheel (4); a handlebar (20); and means (5) for coupling the propulsion system to the roller body, the coupling means (5) comprising means for gripping and lifting at least one wheel of the roller body. The handlebar (20) comprises a connection with the chassis (2) and/or the driven wheel (3). Furthermore, the connection comprises means (12) for locking/unlocking the handlebar (20) relative to the chassis (2) and/or the driven wheel (3) from a locked position, in which the handlebar (20) is attached to the chassis (2) and/or the driven wheel (3), to an unlocked position, in which the handlebar (20) enables the electric propulsion system (1) to move by means of the handlebar (20), the unlocking position enables free movement of the handlebar (20) at least relative to the chassis (2)
