Abstract: A sport wheelchair includes a T-frame that interconnects enlarged rear wheels and a single small diameter caster front wheel. A footrest is adjustably secured to the T-frame and may be adjusted height wise and front to rear as desired by the user. Additionally, handles extend outwardly from opposite sides of the front edge of the seat in selected embodiments of the invention. In some embodiments, a central support member extends upwardly from the seat so that the handles also function for lateral restraint of the user's legs. In still other arrangements, a pair of side supports extend outwardly and downwardly in place of the handles and provide the lateral support as needed.
