Abstract: This invention is in the field of electrically operated amusement vehicles, such as bumper cars and the like, in which the vehicles receive electrical energy from segments of floor material alternately connected to the different poles of a source of electrical energy. This invention is particularly characterized by a means wherein an alternating current source of electricity is connected to the floor material together with an appropriate corrective circuit arrangement in the vehicle to convert, automatically, so as to provide direct current within the vehicles themselves. A particularly unusual feature includes the method of providing multi-phase current in such manner as to provide for increased power and speed to the vehicle depending upon the skill of the operator, together with an electronic speed control.
