Craig Calfee has been challenged with the question: “What is the best bicycle design for developing countries?” for many years. Since 2007, he has made 10 trips to Africa, nurturing his bamboo bike brand, Bamboosero, to produce for the export market. But he hasn’t forgotten the local market. During those trips, he has become involved with several bicycle development projects and researched what the important issues are in designing bikes for the bottom billion. The results will surprise you! Leave all assumptions at the door and attend this in depth look at a fascinating design problem.
