Mountainboarding, also known as Dirtboarding, Offroad Boarding, Grass Boarding, and All-Terrain Boarding (ATB), is a well established if little-known action sport, derived from snowboarding. A mountainboard is made up of components including a deck, bindings to secure the rider to the deck, four wheels with pneumatic tires, and two steering mechanisms known as trucks. Mountainboarders, also known as riders, ride specifically designed boardercross tracks, slopestyle parks, grass hills, woodlands, gravel tracks, streets, skateparks, ski resorts, BMX courses and mountain bike trails. It is this ability to ride such a variety of terrain that makes mountainboarding different from other board sports. Morton Hellig's 'Supercruiser Inc.' was the first company to manufacture and retail the 'All Terrain Dirtboard', patented in 1989. Mountainboarding (name coined by Jason Lee) began in the UK, the USA and Australia in 1992.
