A video has been doing the rounds on social media, which shows a mountain biker riding through the woods in Whitefish, Montana, and being chased by a big black bear.
Montana Knife Company first shared the video on Facebook earlier this month, and captioned it: "A quick reminder that Montana is not Disney Land… Black bear chasing a downhill mountain biker in Whitefish, MT."
If you want to feel a surge of adrenalin, watch this clip to see how close the biker came to being the bear's dinner.
