Marco Facciola, a 16-year-old high school student, had to complete a personal project of a non-academic nature as a requirement for the International Baccalaureate program at his high school. So, drawing inspiration from stories his grandpa told him, he made this working bike completely of wood, including the drive train. Grandpa's stories included making his own wooden bicycle wheels during the war years, since rubber was a scarce commodity. Check out the chain and the pawl arrangement Marco designed, so he can coast down hills on his hand-made wooden single-speed. (Click here for Marco's description of his wood-working and bike-making process.)
