An electrically powered wheelchair has two road wheels (1), each being driven by an electric motor (10) and each road wheel (1) includes a hand wheel (24) with sensor means (27) for controlling the associated electric motor (10), the sensor means (27) responding to forces applied by the user of the chair to the hand wheel (24) relative to the road wheel (1) and thereby controlling movement of the chair by the motors (10). |
