Motorcycle
Compared to a bicycle, a motorcycle requires an added touch of genius to pull off in wooden form. This wooden motorcycle is a replica of an 1895 design by famed automotive engineer and industrialist Gottlieb Daimler.
This Hungarian-made bike is built with mostly wooden parts, even the wheels. I can't imagine it's very efficient mileage-wise, but it is mostly biodegradable. Plus, this wooden hog looks a lot more functional and rocks plenty of steampunk appeal.
