Hand Drive
A wheelchair attachment that could make lever-powered wheelchairs more accessible to everyday users
The Hand Drive is a 3D-printed wheelchair attachment that can be attached to any wheelchair, allowing it to be powered in a rowing motion. This motion is better for your back, as it uses bigger muscle groups, it’s more efficient for your body, and it keeps your hands cleaner. Traditionally levered-powered designs cost anywhere from $2,000-$10,000, but because Hand Drive is almost entirely 3D-printed and completely open source, it costs less than 1% of the competitors’ options.
