The device has a chassis (1) supported on two non- directing wheels and a directing drive wheel (8) and a standing platform (4). Direction is set by handle bars (9). The drive system is an electrical motor (10), whose current is supplied by a battery (14) placed on the rear part (3) of the platform (4). Control and safety of the motor is managed by pressing simultaneously on two push buttons (15) by left and right thumbs. The platform (4) is removed when used as a walking aid. |
