Abstract
The invention relates to a kit providing a wheelchair adaptable in one of a hand powered mode and a motorized mode. The kit comprises: a wheelchair frame with two wheels rotatably mounted; a propulsion unit frame having at least one motor mounted thereto, a right and a left power driven wheels operably and distinctly coupled to the at least one motor, the right and left power driven wheels being characterized by a respective first and second rotation speeds, the at least one motor being coupled with at least one battery and a controller for controlling the first and second rotation speeds; and a mounting structure having at least one first mounting element carried by the propulsion unit frame and at least one second mounting element carried by the wheelchair, the at least one first and second mounting elements being adapted to securably and releasably mate into one another form mounting the propulsion unit to the wheelchair frame, the power driven wheels being located between the wheelchair wheels when the propulsion unit is mounted to the wheelchair.
