Experiments in Speed is a mini documentary about going very, very fast. Tom Donhou, the frame builder behind Donhou Bicycles in Hackney, London, was inspired by the old land speed record attempts at the Bonneville Salt Flats in Utah. The film chronicles Donhouâ€™s fascination with speed, the bikeâ€™s build, and his attempts at pushing the machine to its limits. It is beautifully shot and exciting to watch and a reminder that bicycles are amazing feats of engineering. A simple frame design and one gear enable a human to ride 100 miles per hour. Thatâ€™s incredible.
