What do you think about riding this bike? Nervous.

Bamboo is an incredibly strong material. I've studied Bamboo a lot. I wouldn't mind riding a bike made of it. It gives you plenty of warning before it completely breaks. Just take a piece of bamboo and try to snap it, it will still crack but never break clean.
One thing about that bike is that he will have to change the bamboo once a year. Bamboo naturally contains bacteria that eat it away once it dies. There's no way around this, yet you can smoke treat it to lessen the effect. The Japanese are masters of smoke treating bomboo, but even that doesn't last more than 7 years in a dry place.
Another cool thing about bamboo is that you can heat it up and bend it like glass due to the high silica content. Once it cools it holds its shape. I've done this MANY times with a propane torch.
I scare myself sometimes with how much I know about bamboo. I took a summer long course from a world renound bamboo architect from Italy, Alberto Renaldo. Bamboo is the best building material you can find in nature. It is many time more environmentaly friendly than wood.
BTW, many people think asians are the leaders in bamboo. In fact the Italians are into it more than they are. Italians can also grown certain strains that don't grow in Japan/China.
