Watch a man do 0-62mph in 0.5secs on a water-powered trike

​Hold on tight as Francois Gissy gives you the only lesson in physics you’ll ever need

Published: 19 Sep 2017

We’ve featured French bus driver Francois Gissy – quite possibly the ballsiest person on the planet – here on TopGear.com before.

Three years ago, he rode a rocket-powered bicycle to a jaw-dropping, white-knuckle-inducing, sphincter-puckering speed of 207mph. Yes, you read that right. Two hundred and seven miles an hour. On a push bike. But now, with the help of an extra wheel, he’s producing even more extreme numbers thanks to a home-built tricycle that does 0-62 mph in just 0.55 seconds, can hit 162-mph top speed in just 1/8th mile while being powered by nothing else but compressed air and rainwater.

Yes, Francois has taken that age-old primary school engineering class of bottle rockets and put it on steroids. Lots of steroids. It’s a proper bit of homebrew engineering that’d leave the likes of the Bugatti Chiron, Hennessey’s Venom GT and all the other hyper or electric cars (yes we’re looking at you, Tesla fans) you can think of weeping at the start line.

With a motorcycle front fork, go-kart rear wheels, and a carbon fibre-wrapped aluminium tank holding 35 gallons of rainwater (collected by hand after 76 trips to a reservoir and poured in using a saucepan) that’s been put under the excruciating pressure of 6000 psi of pressure.

All Gissy had to do then was line the trike up on the line, hook it up to some timing equipment. Then, with the touch of a button, all the physics is uncorked and silly, silly numbers happen such as 0-62 mph in just 0.55 seconds while pulling 5.1g. Safe to say a Hulk-like grip is necessary to not topple off the back.

Safe to say, this is probably the eco-friendliest way of going fast. So fast, in fact, you'll see in the video above that around the 60-second mark, the camera's pixels can't keep up. So, your move, electric cars.
