Francois Gissy is a man that knows no fear. He must be, no sane, feeling human would climb onto a bicycle, attach a rocket engine and then try and ride said bicycle to over 200mph.
Gissy however did exactly that, in fact he not only hit 200mph but managed 207mph, in five seconds.
That's right, in five brief seconds he went from standing still to hurtling down a road faster than most supercars on something that you'd normally find clogging up the streets of Oxford.
Having comfortably broken the world record -- and his own -- Gissy then calmly brings the bike back to a more suitable speed using nothing but some breaks and the power of wind resistance to slow him down.
