If you've ever tried pulling any kind of stunt on a fixie, or a road bike, you'll know it's damn hard.
So just get a load of Martyn Ashton. He hopped onto a carbon road bike and managed to nail a backflip on the thing!
Radar Live is all about the love of bikes, whatever you ride. But Martyn really pushed the limits of his Raleigh Avanti Team – we doubt we'll see many guys on the track at Brands Hatch testing theirs in the same way!
Oh, and if you think it looks fairly steep in the vid, get a load of that graffitied slope he tackled...
