The two large front wheels (4) driven by an electric motor (6) and the smaller rear wheels (5) joined to horizontally positioned telescopic bars (7) are fitted with mountain bike tires not fully inflated for a better grip. The cage (9) holding the wheelchair is suspended from the transversal bar (12), keeping the wheelchair always in a vertical position.
