Add CommentVery Innovative. There are Bamboo Bicycles.
Reply | Report Abuse | Link to thisA bamboo bicycle is a bicycle with a frame made out of bamboo, a renewable resource. Custom built and manufactured bamboo bikes have become something of a trend, with producers in the United States, Asia and Africa.
Some of the main features of bamboo designs are vibration damping, crash tolerance, and the natural look of the bike. Vibration damping is one of the most desirable features of such bikes. A bamboo bicycle can offer a very smooth and comfortable ride. As a consequence, bamboo has been made into road bicycles, mountain bikes, and racing
Different methods exist to treat the bamboo poles and make them durable. All methods aim to cure the material in order to improve durability. One company smokes and heat-treats the bamboo. Others use a torch to achieve the same effect. Ovens can also be used. To prevent water-damage the bamboo can be coated with a sealant such as polyurethane.
The bamboo poles can be joined in different ways. The earliest models used metal joints which were then tightened around the bamboo. Another approach is to wrap the joints with resin saturated fibres to make composite lugs around the bamboo frame members.
