Leveraged Freedom Chair

The Leveraged Freedom Chair (LFC) is an all-terrain wheelchair made from bicycle parts.[1][2][3]

History

Amos Winter, a PHD graduate from MIT, travelled to Tanzania during his work, and found that conventional wheelchairs are inadequate in areas without wheelchair accessible roads and buildings.[4] He and his students from his mechanical engineering class worked together on the development of the project. The tests of the LFC were conducted in East Africa, Guatemala and India.[5]

Description

In addition to a normal wheelchair pushrim, the wheelchair has a lever drivetrain that lets the user grip the lever far from the wheel for high torque on rough terrain.The levers can be removed and stored on the chair, allowing it to be used like a normal wheelchair indoors.[6] The wheelchairs are designed to be produced at low cost from commonly available bicycle parts, and to be repaired and maintained at local bicycle shops.

The chair is developed by a group called Global Research Innovation & Technology. The chair is sold at around US $250 to NGOs, less than the price of common wheelchairs.[7]

The GRIT Freedom Chair is an off-road sports chair designed for the developed world. The product launched on Kickstarter with a lowest price point of US$2,195, which sold out.[7]
