Experiments in speed by Spindle Productions. Inspired by those great men of the salt flats, those men that in the 60s pushed the Land Speed Record from the 300s up towards the 600mph mark in jet-propelled cars built in their sheds. Donhou Bicycles decided to do what they do best – build a bicycle, but this time, in the spirit of those pioneers of speed, build it to see how fast they could go.
