WATCH: Heart-stopping stunt on the edge of an Austrian dam

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.
