In 2013, he strapped a rocket to a bicycle and achieved a speed of 285 kilometers per hour (about 177 mph) in 6.7 seconds. Now, he's broken his own record by hitting a speed of 333
kph (about 207 mph), on the Circuit Paul Ricard track located at Le Castellet in the south of France. And he did it using a "skinny and completely stripped bicycle," according to the YouTube video about the feat (see below).
Gizmag reports that Gissy held on to the uber-bike as it let loose the energy equivalent of 560 horsepower and 1.96 Gs.
The bike was propelled by a cluster of three small rockets fueled with hydrogen peroxide. Not only were they enough to get Gissy to record-breaking speeds, they were also enough to make a Ferrari 430 Scuderia with 650 horses under its hood look like a Ford Fiesta as he left it far behind near the starting line, as you'll see in the video.
