This is definitely NOT one to try at home!

Mat Olsen wowed onlookers with his stunt ride along the top of the Seventh Street bridge in Fort Worth in Texas in America.

He rode across the six arches luckily without falling off or getting hurt!

The 25 year old is a professional biker but police still gave him a warning for doing such a dangerous stunt.
