On November 7th of 2014, on the Circuit Paul Ricard located at Le Castellet in South of France, I have reached a speed of 333 km/h on a rocket-propelled bicycle, after only 4.8 seconds of acceleration. A velocity of more than 300 km/h on a skinny and completely stripped bicycle, this is amazing, and a bit crazy! Who thought that one day a daredevil on a bicycle, with a rocket under the saddle, could travel the quarter-mile in less than 7 seconds?
