Abstract: The vehicle has a support component which has two wheels and a frame work supporting a seat above and forward of the two wheels, a second steering component which has a wheel and means for steering the wheel and means disposed just above ground level for connecting the components so that a provisionally ambulatory medical patient who is either weak from disease or injury or who is partially crippled can mount the self-supporting vehicle and ride it from point to point without changing from a standing position.
