Travis Pastrana put his skills to the test as part of the launch of Nitro Circus' UK and European tour.
Organisers say he pulled off the stunt on Thursday, while battling high winds and rain to launch himself from one barge to another on the River Thames.
Here is the stunt once again, in slow-motion:
"I definitely couldn't breathe while he was doing it. It was so incredibly windy I thought even I'd blow into the Thames," tweeted one person who witnessed the stunt as it happened. "He makes it look so easy," tweeted another.
