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.

In this game it will be possible to actually make custom made Extreme Gears using pre-existing parts of other board, bikes and yachts you unlocked or purchased in the game. Extreme Gear will come in 3 major parts. The front, the stand or seat and the engine. Once the parts have been chosen the Extreme Gear can be coloured and decorated with patterns. Afterwards the player can add 3-5 gears, primary gear and 2 or 4 secondary gears that can be unclocked and switched during race. Depending on what parts and gears you use may cause the Extreme Gear to transform during racing, such as from a board to a bike, though non-board Extreme Gears can also be made. After an Extreme Gear is made you can name them and write a description for them. Custom made Extreme Gears will be used by everyone (except Dr. Eggman who can ride custom made bikes). It is undecided if Skate or Wheel Gears will be reintroduced.
- Also, "Yacht" Extreme Gears are now scooter like and handled like waterskiing.
