BC Racers is a kart racing game starring characters from the Core Design's Chuck Rock series of games. Each of the racers in this game rides a prehistoric motorcycle with a side car. On each two-character team, one person drives the motorcycle, and the other fights off opponents using clubs, punches, kicks, etc. Graphics in BC Racers consist of a flat landscape decorated with scaled sprites to compose the track and scenery.

The millionaire playboy caveman Millstone Rockafella has organized a BC bike race, the winner of which will receive the Ultimate Boulderdash Bike. Six groups of riders - one driving, one deploying weapons from the sidecar - from all around the prehistoric world will use their rock-powered sidecars to compete for this prize.
