Specifically, this bamboo bike:
Background: There is a small startup here in Fort Collins, CO, that is selling bamboo frames and bikes. I'm not actually in the market for a new bike (hmmm, I'm going to get laughed at for saying that), but the claim is that "Iron Bamboo" is strong, light and durable. And it certainly stands out.
Here's their web site: http://www.pandabicycles.com/
What do you think of it?
