New push-pull wheelchair

Procubed LLC built a better wheelchair. They say the average manual wheelchair driver puts in 3,000-4,000 strokes per day, which can take a huge toll on the shoulders, elbows, wrists and hands. This contraption, the Linear to Rotary Motion (LRM) drive system, while not the first drive system using push levers instead of drive wheels, is wonderfully elegant. I hope it goes on the market as planned.
