French cyclist François Gissy (aka "rocketman340" on YouTube) likes to go fast.
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 below.
"If we can find some serious sponsors, then we would like to build a monstrous bicycle, which will be called 'Spine Crusher,' Gissy told Gizmag's Loz Blain regarding what's next. "The goal would be to accelerate to more than 400 kph (249 mph) in less than 2 seconds. I just cross my fingers that we will have the green light soon in order to start the construction."
