Tim Egan was on a bike ride in Boulder County when he had an unexpected collision with a bear he estimates weighed 500 pounds and was six feet tall, KCNC-TV, Denver, reported.

"This bear looked at me with a look of terror on his face and sort of made a noise. I looked at him with a look of terror and we went, 'aaaahhhhh'," Egan said.

Egan, 53, said his bike flipped over the bear and smacked the pavement before the huge animal ran away.

"When I tell people, they say 'Right, are you kidding me, who hits a bear?'" he said.

Egan said he was able to ride his bike to a medical center to get treatment for cracked ribs, cuts and abrasions after Tuesday's incident.
