A wheelchair, for either street or sports (e.g. racing) use, is comfortable and easy-to-use, lightweight, and may be folded compactly for transportation. A plastic pallet supports a collapsible chair frame, and is mounted to a base frame for adjustment along the base frame to thereby adjust the center of gravity of the wheelchair. The rear drive wheels and the caster-type front wheels are both mounted to the frame for easy removal, utilizing a split-block receiving the spindle or shaft from the wheels. The blocks may be pivoted about axes perpendicular to the axes of rotation of the rear wheels to adjust the camber of the wheels, and--by effecting flexing of a leaf spring to which the blocks are mounted--the toe of the rear wheels may be adjusted.
