However, this also meant that, in order to get going, the bike had to be pushed by a motorcycle with a lance, as the cyclist alone could not generate sufficient power. With a crank revolution of around 110 centimetres, the bike had an exceptionally large gear ratio – Rude was able to cover a distance of up to 27 meters per chain ring revolution. The front gearwheel was almost the same circumference as the front wheel, while the rear gearwheel was only around two centimetres in diameter. The bicycle used was no ordinary model, either. Even with this additional structure, the Porsche 935 had sufficient power to achieve the desired speed.Ī roller along the length of the bumper allowed the front wheel of Jean-Claude Rude’s bike to effectively “stick” to the rear of the Porsche 935, making sure that he stayed right in the slipstream. A trapezoidal screen spanned the rear of the Porsche to ensure maximum slipstream. An 800-hp 935 Turbo from the Martini Racing team, with an ingenious roof construction fitted especially for this record attempt, was exactly the right car to serve as pacemaker for the world record bid. The only thing missing now was a powerful car, which is where Porsche came into play.
