Just when I thought I had seen it all (aka bamboo bikes), Nate sends me a link to a craftsman in Japan who makes wooden bicycles out of mahogany. Cute, you think. Toy wood bikes..... only these are high-end, custom racing bikes. Real bikes.
The maker, Suehiro Sano, is a 9th generation craftsman. Apparently he made high end wooden boats before going into bicycles.
Sano's website is here: http://sanomagic.world.coocan.jp/englishindex.html
