The Big Boda Project is a test-market of Worldbike's lowest-cost technology, the Big Boda. This bicycle extension attaches, in turn, to the lowest cost bicycle available in the developing world, the 'black mamba'. Most bicycles sold in the developing world are made in India and China. But the needs of the developing world customer are often lost. In Kisumu, Kenya, where the Big Boda Project is based, most Boda Boda taxi operators modify their steeds with passenger seats and change the riding geometry with locally-made seatposts, in order to provide more room for their passengers.

The frame modification typically costs Boda Boda operators a premium of 15-20% over the base cost of a bicycle. And they suffer from worsened ergonomics and power output. Knees of taller riders can hit the handlebars, and some may experience cycling-related impotence, though this may be attributed to the hard plastic saddles. The Big Boda project produced an initial run of 50 Big Boda cargo extensions and sold them locally. We also donated two complete Big Boda bicycles to the Young Generation Center, a local orphanage, and one to a Malaria clinic in Jinja, Uganda.
