Biker's Camera Shows Bear Chasing Fellow Rider

Biking can be a fun way to burn calories while enjoying nature in all its beauty...when bears aren't lurking on the trail.

A Slovakian rider's helmet camera was rolling when a bear started chasing his friend. The massive mammal eventually retreated into the woods, leaving the bikers unharmed.

The terrifying moment has now drawn more than a million YouTube views.
