Now that you have heat treated the bamboo you need, cut, miter and tack the frame together. My wood saw had no trouble cutting the green bamboo but I had to use a hacksaw to cut the treated bamboo. Heat treating turns relatively soft bamboo into a super hard material. Another thing, I only did one section at a time (from one node to the next). I also had a few dry pieces (already light brown) and only treated them once to get them to a dark brown color. The second step is turn the light brown sections to a dark brown. The first step is to turn the green sections to a light brown. The trick is to heat the bamboo evenly and slowly.

Using new and untested techniques is risky. Disclaimer: Death or serious injury can result from a bicycle frame failure. The track bike also makes it easy in that it is a very simple bike - no gears, cable routings, rear brake or derailers. I used epoxy and hemp fibers on all the joints (no pun intended). I really wanted something with a minimum of fancy technology and carbon fiber (although I sprang for the carbon fork). The bicycle was inspired by Craig Calfee who makes much nicer bamboo bikes. The bike I made is a track bike for commuting to work. I had a lot of fun and I hope that you can make one too by following these instructions. ![]() I found out that professionally built bamboo frames cost a few thousand dollars so I decided to build one myself. I saw a picture of a bamboo bike and decided I had to have one. ![]()
