Abstract: A steerable, electrically powered, three wheeled vehicle has a frame with a front end extending upwardly at a restricted angle. Laterally spaced apart rear wheels supporting the rear end, a steerable front wheel, journaled by the said front end for steerability, supports said front end. An elevated seat is supported on said rear end and a steering post connected to said front wheel extends upwardly at an angle at which it can be readily grasped by a seat occupant. Rechargeable batteris are carried in a well in a rear casing and the well and batteries have resilient contacts and terminals which automatically engage when the batteries are slipped into position in the well. An electric motor and drive mechanism is connected to drive said rear wheels, and demountable auxiliary wheels are detent secured to be driven with the rear wheels.

Abstract: A steerable, powered, front wheel driven, three-wheeled vehicle for a handicapped person which is movable selectively in a forward or rearward direction and has a vehicle frame supported in part by a pair of transversely spaced rear wheels suitable for indoor travel, is adapted to outdoor use by backing its rear wheels onto a transversely extending, auxiliary frame supported on a pair of transversely spaced driven outdoor wheels. The auxiliary frame has a transversely extending cradle mounted such that, in a first forwardly and downwardly tilted position of the auxiliary wheel frame, the forward portion of the cradle rests substantially on the ground and, in a second position, in which the frame is generally level, the front and rear portions of the cradle are both disposed above the ground, and the rear wheels of the powered vehicle are supported by the cradle above the ground.
