anonymous on 21 Feb 17The concept of power assistance for a Wheelchair 4 Wheel is relatively new, and represents a viable alternative for individuals who are unable to generate sufficient propulsion force to use a Wheelchair 4 Wheel, but do not wish to use a traditional powered mobility device. In a power assisted manual wheelchair, the traditional rear wheel hubs are replaced with motorized hubs that serve to magnify or reduce (i.e., brake) the propulsive force applied to the rear wheel push rims by the user.
