This 'All Wood' Bicycle Can Go Pretty Fast: The Splinter Bike

The SplinterBike, as its called, is a bicycle that's made completely from wood. Others have done similar 'all wood' bicycles before but this one is supposed to be the fastest—it can hit 31mph.

There's a lot of different wood in this bike! 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.
