The RoTrike is a human-powered scooter that is rowed by pushing and pulling on a central lever
Imagine if the only way of propelling yourself on a bicycle was to reach down and turn one of the wheels with your hand. It would be pretty inefficient, yet that’s essentially how a wheelchair works. Of course, wheelchairs are set up so that the push-rims can be reached very easily, but the propulsion process still comes down to the wheels being directly pushed forward by hand. ROTA Mobility, however, has an alternative. It’s called the RoChair, and it’s a wheelchair that is rowed by pushing and pulling on a front-and-center-mounted lever.
