Huge bear chases mountain biker through forest

Incredible footage has emerged of the moment a downhill mountain biker was chased through a Slovakian forest by a bear protecting its territory.

The video, captured by filmmaker Dušan Vinžík, shows his friend being aggressively pursued by a huge brown bear as he rode through a trail at the Malinô Brdo Bikepark in Ružomberok.

The bear can be seen emerging from the woods just as the bikers cycle past, and chasing after the one in front - but it's short-lived as the cyclist is moving too quickly.

Oddly, the bear doesn't seem too interested in the cyclist filming, and instead of turning and chasing what would be a much simpler target, it turns and heads back into the forest.

Slovakia, which has a large bear population thanks to the animals being protected under law, is home to many brown bears, which are closely related to North America's grizzlies.

The video has drawn huge audiences worldwide, with the original YouTube video attracting more than 3.3 million views in less than 48 hours.
