This is the moment when stunt rider Travis Pastrana successfully does the first motorbike backflip while floating on water.

The American, 33, backflipped a 75-foot wide gap between two barges floating on the Thames River opposite the O2 Arena.

Pastrana only had 150 feet to accelerate to takeoff speed and after landing only had 36 feet to come to a stop.
