The fastest a man ever traveled under Motor-paced human propulsion was 167 mph (268 km/h). It's hard to comprehend, considering we rarely crack 100 mph on our motorcycles. Full disclosure; it's scary as hell and the thought of peddling a bicycle anywhere near that speed is just unfathomable. Luckily we have shops like Donhou Bicycles in Hackney, London to step up to the plate making it a little harder to look in the mirror and call ourselves men. They also earned some extra style points by doing it in the wake of a Ford Zephyr 6 Mark III. We love this kind of ambition.
