Abstract

An electrically powered vehicle having two primary ground engaging wheels (5) operatively connected to a driving motor (10) by an automatic transmission (50) and to a steering motor (20) by a shiftable bevel gear (7b) which permits opposite variations in rotational speed of the ground engaging wheels (5).
