A transport apparatus for disabled individuals has a frame for carrying a driver, drive wheels, at least one front wheel, a back support and a push structure. The drive wheels are removable connected to drive wheel mounts. Those mounts are positioned on the frame near the rear of the frame. The front wheel is connected to a rotating fork that is mounted to the front of the frame by a fork mount. The push structure extends upward from the rear of the frame and is positioned behind the back support. For overcoming obstacles, pre-wheels are connected to the frame on mounts positioned ahead of the drive wheel mounts. For travel on narrow trails, the pre-wheels are removed from the side mounts and connected to an auxiliary mount attached to the rear of the frame. Once on the auxiliary mount, the drive wheels are removed and the pre-wheels serve as the rear support for the apparatus. A steering bar is coupled to the front of the frame for towing applications and for steering purposes. Harnesses are connectable to the apparatus for off-road wilderness expeditions. The width of the apparatus is reduced by activating wheeled extensions connected to the rear of the apparatus. The extensions have rotating arms hinged to the rear of the frame. When narrow doorways are encountered, the extensions are rotated to active positions and the drive wheels are lifted from the ground. The wheels of the extensions serve as the rear wheel support of the apparatus, and the drive wheels are removed, thereby reducing the width of the apparatus.
