The Splinter Bike is made all of wood, no metal screws, no rubber, nothing. Most of the wood is reclaimed. Built by Michael Thompson of the UK.
How it Began? “Thompson, a joiner, boasted he could make a fully wooden bike and his friend James Tully called his bluff.
The cogs, wheels and frame are made from birch ply. Ironwood – an oily wood – is used where moving parts meet. The pedals and handlebars were made from an old broom handle. There’s no chain. Instead there’s a 128-tooth cog that links the chainring and the gear on the rear wheel.” (Bike Biz)
