A few weeks ago, Gizmag (http://www.gizmag.com/cardboard-bike/24573/) covered the story of Izhar Gafhi, who recently designed and prototyped a bicycle built from cardboard. In its current design, it cots US $12 to build, can withstand moisture/water/humidity, and can support riders weighing up to 485 pounds. Additionally, Gafhi uses recycled car tiers for the tires and repurposes a car timing belt as the bike chain.
