Conventional wheelchairs aren't really an option in many parts of Africa – they're too expensive and they just can't handle the conditions. So often people with mobility issues just have to get around as best they can on their own, or with the help of their family and friends.
Janna Deeble grew up in Kenya and saw the problem for himself. His SafariSeat is a rugged, low-cost wheelchair made from bicycle parts, that can be assembled by just about anyone using easy, open-source plans.
