Abstract A personal mobility vehicle having a novel support mechanism for the front wheel which maximizes the amount of foot space available for the occupant of the vehicle. The mobility vehicle has a main tubular base frame formed by laterally spaced, longitudinally extending side members joined by a front nose section. The front wheel is mounted within and behind the front nose section by a novel bracket assembly which maximizes the amount of foot space available on the floor board around the wheel housing.
