Abstract
A personal mobility vehicle includes a main frame unit with front and back ends, both with wheels thereon, a steerable front wheel, an operator's seat and vehicle controls. A pair of spaced rear wheels are mounted at the back end of the vehicle and include moveably mounted axles supporting the rear wheels and connected to arms with mechanisms for selectively angularly moving the axles outwardly and inwardly of the main frame unit to vary wheel base and wheel track. A motor is connected to the wheel support structure for remotely varying the wheel base and wheel track. A separate drive motor is operatively connected to the wheels for movement of the vehicle.
