Abstract: A traction enhancement device and system for the rear wheel(s) of a wheelchair is provided. The traction enhancement system generally includes a tooth bar assembly that includes a plurality of spikes/teeth and an actuation assembly that includes a lever and swashplate. In use the lever can be moved into ground engaging position and the swashplate will contact and provide a force the tooth bar assembly causing the spikes to extend beyond the diameter of the wheelchair wheel and into engagement with the surface on which the chair is riding. The lever can be pulled out of ground engaging position and the swashplate will not cause the spikes to push outwardly beyond the diameter of the wheel.
