This is what 5.13 Gs at launch looks like

The race to be “the fastest and most powerful” is a real thing in the auto industry. But give me a car – the Bugatti Chiron, Koenigsegg One:1, or any of those hypercars – and I’ll raise you this water-powered rocket bike. If you want to talk about speed, this little devil goes in front of the line.

This bike is the creation of a Francois Gissy, who some of you may remember as the same person who once trashed a Ferrari 430 Scuderia back in 2014 using a similar rocket-powered bicycle. Well, Gissy’s back in the news with a new creation that makes the Chirons and One:1s of the world look like tortoises by comparison. The Frenchman even went to the Circuit Paul Ricard in France to test out his new bike and, boy oh boy, serious fireworks happened. Imagine this: the water-powered rocket bike accelerated from 0 to 60 mph in 0.55 seconds. 0.55 seconds! That’s almost four times faster than today’s fastest-accelerating supercars. That’s not all, either. Gissy also managed to cover a quarter-mile distance in 3.95 seconds, quicker than the 0-to-60-mph acceleration time of most of today’s sports cars.

Here’s the craziest part, though. According to Gissy, the bike’s ungodly acceleration time creates G-forces that are far more brutal to the body than what astronauts experience when they’re launched into outer space. Gissy claims 5.13 Gs, to be exact. These numbers delivered by the water-powered rocket bike are beyond belief. Seriously, they sound ridiculous to the point of cartoonish. The good news is that for those who are skeptical of what Gissy was able to accomplish, there’s video evidence of him actually putting his creation to the test. Trust me when I tell you, it gets all sorts of crazy.

Kirby’s first exposure into the world of automobiles happened when he caught Knight Rider on television as a five-year old boy. David Hasselhoff didn’t leave much of an impression on him (that happened later on in Baywatch), but KITT certainly did. To this day, Kirby remains convinced that he will one day own a car with the same ‘spirit’ as the original KITT (not the 2008 monstrosity). He doesn't know when that will be, but until then, he’s committed to expressing his love for KITT, and all cars for that matter, here at TopSpeed.  Read More
