Here’s a great wooden bike project; The SplinterBike!
No bolts or screws, just wood and glues!
…a 100% Wooden Bicycle Land Speed Record… attempt!
The bike is built completely from wood; no spokes, no chains, no metal anywhere (although it appears he did resort to using some nylon bushings when he discovered that no matter what species of wood is used, it doesn’t make a good bearing surface.) Even the drive system is made from wood; a wooden chain probably wouldn’t be strong enough so the builder went with a huge cog system instead.
The bike was built intending to set a world speed record for an all wood bike, and they did it; 18.11kph (11.25mph)… Wait, what? 11.25mph?!? Not exactly breathtaking, but I guess it’s something. I think I could do better. Time to hone my woodworking skills, then next stop; Guinness Book Of World Records!
