“About two years ago I saw a vedio about Calfee Design bamboo bicycle, that attracted me and I began to make the bamboo bicycle by myself.
I made several bamboo bicycles and now I treat it as a habit. I spent most of my off hours to research and build. Pls see the attched files for one of my bamboo bicycle.
As you blog wrote every details of making the bamboo frame—but I can’t open most of the pictures, I compared your process with mine, most of that is similar.
I treat the seatpost very simple—I have a hand tool can dig the hole into the poles for the dimater (25.4 or 27.2) as I want, so I just dig the hole and put the seatpost into the bamboo poles, and then lock on the bamboo poles. I didn’t use a metal poles into the poles as you done. The bicycle I rided over 3000km and still OK. ”

One very interesting thing about this approach is the use of foam blocks. Clearly this reduces the amount of epoxy and fiber you have to use while cutting down on weight. It’s not clear to me whether the ends of these tubes have been mitered or not. This approach is much more like that used on carbon fiber bikes, where a foam frame is built, carbon applied and then the foam gets melted out using acetone. I would assume they leave the foam in here.
