The bamboo frame started as a stunt in 1996. Calfee Design also won best tandem award at the 2010 North American Handmade Bike Show with a carbon fiber 21 pound tandem Dragonfly bike.
Calfee Design manufactures a bamboo bicycle. Craig Calfee started another business, Bamboosero, with the intention of providing employment opportunities in developing countries. Bamboosero establishes frame building business by providing training, tools, supply chain, and technical support. Bamboosero acts as a customer by purchasing frames from the fledgling (primarily African) businesses in order to resell the bamboo frames in North Americans and Europe.
