In China, a bike-riding bear ended its race with a bike-riding monkey . . . by trying to EAT said monkey.

It happened on Sunday at the Shanghai Wildlife Park . . . which apparently operates more like a circus than a zoo.

According to a park official, the bear was wearing a muzzle, and the monkey, quote, "wasn't hurt" . . . which is hard to believe. There's a blurry video of it on YouTube, and animal rights activists are demanding an end to the bike races.
