amazing wooden bicycle


 This bike is not messing around. Not your typical woodshop project. Not a single bolt or screw has been used, nothing metal, plastic or rubber."ore than 1,000 man hours and a considerable amount of skill and ingenuity later, the SplinterBike was ready to ride.

"The axles are made of the hardwood ekki; the cogs, wheels and frame are birch ply; and oily ironwood was used in place of metal bearings where moving parts met. The pedals and handlebars were made from an old broom handle salvaged from Michael's shed.

The trickiest part was the drivetrain – how do you make a wooden chain?

Well, by cunningly replacing it with a huge 128-tooth cog that links the chainring and the gear on the rear wheel. In fact there are six cogs, as the drivetrain is replicated on both sides of the frame to add strength."
