Well if you’re going to be climbing any hills, this bike might not be for you. Instead of going light, this builder went for unique. The bike is beautiful but weighs in at 114 pounds. The bike was built by a student in Germany. Though at a glance it looks like one beautiful piece of driftwood, it was built by gluing several layers of beech plywood and then lots of woodworking. Truly a one of a kind bike. There are more photos of the bike here.
Right after I bought my bike, I found one I liked even more. Of course if I recall, it cost about 3 times more than mine, and the waiting list was pretty long. But a bamboo bike would have been pretty sweet.
