High school student Marco Facciola (16 years old) built an all-wood bike for a class project. Though this bike may not be very practical, it’s definitely a conversation piece. Click here for first picture in gallery.
The detail in the free-wheeling ratchet and spacers between the chain links, pinned with tiny dowels, is amazing. Marco had to complete this as a non-academic project for his International Baccalaureate, and inspiration came from his grandfather, forced to make wooden wheels for his bike during the war due to rubber shortages
