Motocross and freestyle motocross tricks just keep getting sicker.

About a decade ago, mas 'o menos, Travis Pastrana set the bar on backflips at two. He's done plenty of other crazy things but that particular stunt looked like it would always rest at two flips. Max.

Free stylists moved on to other stunts like leaping on and off of huge buildings and other assorted madness like repurposing old Olympic luge courses and ski jumps. Then, taking things even farther, came The Nitro Circus. They aren't happy with just bikes. They use quads, wheelchairs, shopping carts and pretty much anything else with wheels.

The third backflip though had always eluded riders until Josh Sheehan nailed it. So many aspects of the sport are owed to, and/or inspired by, Pastrana that it's only fitting his double was finally bested in his private park, Pastranaland.
