The idea is to create a wheelchair that will be propelled by the user pushing and pulling on a center mounted lever.
Such a chair will offer a better mechanical advantage while also reducing the chances of repetitive strain injuries. It will be steered by turning the center propulsion lever to the left or right, and brake levers mounted on the handlebar will control the dual disc brakes. There will be eight gears available, and the chair will still be maneuvered by the traditional push rims if required.
