A Shandong carpenter named Peijia Wu has created a bicycle made entirely out of wood.
The 55-year-old from Nanzhuang village, near Qingdao, took three months to build the two-wheeler. It has no metal parts whatsoever – the joints were fixed with small wooden bungs and the chain mechanism was replaced by a rod-crank system that rotates the wheel.
As it turns out, this isn’t a first. 16 year-old Marco Facciola built this completely wooden bike for a school project. His version even has a chain and gearing made of wood, held together with wooden joints and glue. The detail in the free-wheeling ratchet and spacers between the chain links, pinned with tiny dowels, is amazing.
