This 21-year-old adrenaline junkie is living the dream by stunt biking around the world and his latest video is terrifying.
Wearing a Go-Pro Fabio Wibmer, from Austria, bikes along a narrow ridge of a 200 metre Dam.
Clearly not a job for the faint hearted, the young man filmed this heart-stopping video at the Koelnbreinsperre dam in southern Austria, which is one of the highest in Europe.
We think it goes without saying, but don't try something like this at home!
