A prosthetic leg can cost thousands of dollars, and in many developing nations, that puts it out of reach for the vast majority of people who need one. Ben Hogan, a prosthetist at Mary Free Bed Rehabilitation Hospital in Michigan, decided the solution might already be sitting in garages and bike shops around the world. His creation, Project Bike Leg, is made from over 95% bicycle parts: a bike seat serves as the foot, chains provide knee stability, gear cables hold the frame together, and wicker forms the socket.
Hogan traveled to Ghana for nine days to train local people to build the legs themselves, and two amputees walked again as a result. He has no plans to patent the design or profit from it. Instead, his website offers free instructional videos for both above-the-knee and below-the-knee prosthetics, so anyone with basic tools and access to bicycle parts can learn to build one. The next phase is a pilot study of amputees in developing countries wearing bike legs full time.
For those of us on the Suncoast, where bicycles are everywhere and community workshops are plentiful, it’s a reminder that innovation doesn’t always require a lab or a big budget. Sometimes it just takes seeing everyday parts in a brand new way. Could a design like this take root in Florida’s own cycling community? Let us know what you think in the comments.
