SHOP now: About us: Nitro Circus is what happens when a group of extremely talented and fearless friends decides to make their hobby into their profession. This crew of wild ones represents a cross section of everything awesome in action sports: freestyle motocross, BMX, skateboarding, scooter, snowboarding, skiing, BASE jumping, sky diving, and a bunch of stuff that shouldn't be taken down a ramp. Nitro Circus tours the world putting on shows featuring all of the above and more. In our constant quest to always do what we love and push the boundaries of what's possible in action sports, we have some epic crashes and legendary fails, but stick or stack, our only goal is to have fun and entertain the world in the process.
