A power add-on device (100) for powering a manual wheelchair includes a motorized component including dual electric motors (502) and a power source (515, 516) electrically coupled to the electric motors (502), wherein each of the motors (502) is configured to turn a respective one of a set of drive wheels (104). The power add-on device (100) includes a latching mechanism (103) adapted to attach the power add-on device (100) to the camber tube of the manual wheelchair; and a controller (108), reachable by a person sitting in the manual wheelchair, that controls the latching mechanism (103), the motors, and a swing arm that allows the rear wheels of the manual wheelchair to be lifted off the ground. The front wheels of the manual wheelchair are allowed to be lifted several inches off the ground to avoid obstacles, or can be lifted by the user leaning back. |
