A bicycle frame, spokes and a woven basket might seem unlikely materials for a prosthetic limb. For Ben Hogan, a Michigan-based prosthetist and former bicycle mechanic, they became the starting point for an initiative aimed at making mobility more accessible.
Mary Free Bed Rehabilitation describes Hogan’s working prototype as a lightweight, adjustable prosthetic leg built largely from bicycle components, including a basket adapted into a socket. His professional journey combines bicycle repair, formal prosthetics and orthotics education, and experience providing rehabilitation care.
For the orthotics and prosthetics community across the Middle East, Africa and South Asia, the project raises an important question: how can locally available materials support affordable prosthetic services while maintaining clinical quality?
Sharing knowledge across borders
An October 4 PEOPLE report brought renewed attention to Hogan’s initiative. It describes his development of below-knee and above-knee designs and a nine-day visit to Ghana, where he taught prosthetics students to reproduce them. Two prostheses were completed during the visit.
Hogan also told the publication that he does not intend to patent the designs or benefit financially from them. Sharing the approach is central to his ambition to extend access.
The Ghana experience introduces a practical dimension to the story: transferring fabrication knowledge to local trainees. For IMEA CPO readers, that makes the initiative relevant to discussions about education, workshop capacity and sustainable partnerships.
Designing around available resources
The Project Bike Leg website provides illustrated guides, videos and downloadable fabrication documents for below-knee and above-knee versions. It describes adjustments for height, foot rotation and plantarflexion or dorsiflexion, alongside a socket with cable-controlled compression.
The project’s stated goal is to enable trained people to construct functional, adjustable prostheses using materials available to them. Its website also carries an explicit warning that fabrication and use are undertaken at the user’s own risk. These are project descriptions and design objectives; they should not be interpreted as independent confirmation of clinical performance.
From a service-planning perspective, the attraction is understandable. An approach that uses accessible materials could potentially make repairs and component replacement easier. Whether that advantage holds in a particular location would need to be assessed through local sourcing, fabrication and patient follow-up.
Engineering students help develop the concept
Michigan State University has documented a student engineering collaboration with Hogan and MSU Bikes. A senior team designed, prototyped and tested a lower-limb prosthesis using bicycle parts and basic workshop tools.
The university reports that finite element analysis informed design decisions, while successive versions explored improvements in comfort, stability and adjustability. Students also worked on illustrated instructions to make the fabrication process easier to reproduce.
This collaboration offers a useful model for regional education programmes: connect engineering students with prosthetists, technicians and service users around a clearly defined access problem. Reproducibility, repairability and the resources required to build a device are valuable subjects for investigation alongside its mechanical performance.
Affordability depends on the whole service
The wider access challenge extends beyond component prices. The World Health Organization’s prosthetics and orthotics guidance emphasizes regular access to qualified teams, equipped workshops and links with rehabilitation and related health services. Its standards address policy, products, personnel and service provision together.
Applied to Project Bike Leg, this means any evaluation should examine the complete care pathway. Proposed measures could include fabrication time, total fitting cost, repair frequency, patient comfort, mobility and continued use. A low material cost would be most meaningful if it translated into a dependable, affordable service over time.
For potential clinical partners, further questions include component consistency, structural durability, socket suitability and how outcomes would be documented. These are considerations for evaluation, rather than findings established by the news coverage.
A practical conversation for the IMEA region
Project Bike Leg offers rehabilitation centres, universities and humanitarian organisations a concrete starting point for discussing local fabrication. A useful partnership could bring together clinical supervision, engineering assessment, technician training and structured follow-up.
Its broader contribution is to make repairability and local capability visible within the prosthetic access debate. For suppliers and service providers, the opportunity is to investigate how materials, skills and ongoing support can work together to reduce the cost of care.
The next meaningful step will be evidence showing where the approach works, for whom, and with what support. That would help turn an inventive design into an informed option for expanding prosthetic access.
