Extreme Gear, sometimes known as EX, is a mode of transportation in Earth/Mobius. They are capable of allowing their rider to fly, or at least hover, at high speeds, and can reach speeds of 200 to almost 400 miles-per-hour. Originally, they had to be fuelled by air, but, thanks to the discovery by Orez Yt-Ivarg, the need of air was dropped. The EX World Grand Prix and International Extreme Gear Competition are both tournaments for Extreme Gear racers. The Prix is held at Metal City, while the I.E.G.C is commonly held annually at Megalo. Notable EX producing companies include Accevive Corporation (As mentioned in Sonic Riders: Zero Gravity), NONAgear created by Delani the Rabbit and its rival Triple X.
