Wheelchair for the developing world: cheap, rugged and easy to maintain

Wheelchair for the developing world: cheap, rugged and easy to maintain: "

Core77's case-study of the MIT Mobility Lab's 'Leveraged Freedom Chair' is a fascinating look at the difficulties presented by designing a sustainable wheelchair for use by disabled people in the developing world. The final product can be sold for $100 -- a 90 percent reduction off traditional wheelchairs -- and uses a lever-driven propulsion system that works better over rough terrain. It uses bicycle parts to keep costs down and simplify maintenance.
