Speed cycling doesn't involve pedaling, but it does require a hefty dose of audacity. Frenchman Francois Gissy hit 207 miles per hour on his rocket-powered bike last week, breaking his own world record of 163 mph.
He hit top speed in just 4.8 seconds - faster than a Ferrari, Outside Magazine points out, with help from Swiss company Exotic Thermal Engineering, which built the rocket.

"In the moment it is scary, but as soon you stop, you also realize how amazing that was," he told GizMag. "You cannot describe it, you have to live it...I'm lucky my head is still bolted on the body!"
"If we can find some serious sponsors, then we would like to build a monstrous bicycle, which will be called 'Spine Crusher,'" he said. "The goal would be to accelerate to more than 400 km/h (249 mph) in less than two seconds...We also have a very powerful motorcycle waiting in our drawers, but I guess I like the craziness of the bicycle too much. Maybe when I will get too old I will start to think about the comfort of a motorcycle."
