It may surprise some people that there are so many uses for bamboo. Many structural devices can be made from the material. Including bicycles. Yes, that's right! Not only is bamboo sufficiently stiff, it also is quite light, making it a great material for the construction of bike frames. The stalks grow in a nice "tube" shape, making the frames compatible with bicycle accessories and equipment.
As you can see from this article
, ready-made bamboo frames are available from a few manufacturers. Or, if you wanted to be super-resourceful, you could make your own using carbon-fiber and\or fiberglass as the connecting material. Wanna know how? See this site
