Extreme Gear

Extreme Gear is the main mode of locomotion in Sonic Riders and its sequel, Zero Gravity. 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. In Sonic Riders, Extreme Gear required the use of air as fuel, but this concept was dropped in Zero Gravity for the use of a Gravity Meter. Extreme Gear is the way of choice to get around for the Babylon Rogues, as well as Sonic, Tails, Knuckles, and Amy during the Sonic Riders games. The EX World Grand Prix is an international tournament, centered in Metal City, for Extreme Gear riders.

Types of Extreme Gear
Extreme Gear comes in several different varieties, each with different attributes in top speed, acceleration, handling, cornering, and power. Every character has a "starting Gear" with statistics specially designed for that rider, and in most cases only that rider can use that Gear.

Boards
Boards are the most common Extreme Gear, and the first available to the player in either game. In fact, they are so common that almost every character's "starting Gear" is a board. In Sonic Riders, boards are the more balanced class of Gear, having average statistics and an average rate of fuel-consumption (in this case air), and is used in Story Mode by every character except Dr. Eggman. In Zero Gravity, Boards are again a balanced, middle class, with average statistics, and allow the rider to grind on rails (an ability previously restricted to characters, not their Gear). Every character in both games rides a board (or can ride a board) except Dr. Eggman, who rides bikes, and the SCR robots, who use Wheels.

Skates
Skates are a less powerful class of extreme gear, but are more agile and, in Sonic Riders, are more fuel-efficient. In Zero Gravity, skates are one of the two classes of Gear that can allow their rider to grind on rails (an ability previously restricted to characters, not their Gear). In Sonic Riders, skates must first be unlocked by completing the Heroes Story Mode before they can be bought, much less used. Shadow the Hedgehog is the only character who rides skates as his "starting Gear". All characters can use skates except Dr. Eggman, who rides bikes, the E-10000 robots, who can only ride boards, and the SCR robots, who use Wheels.

Bikes
Bikes are a more powerful but less maneuverable class of Extreme Gear. In Sonic Riders, bikes are also less fuel efficient. In Zero Gravity, bikes allow the rider to smash trough obstacles and barricades (an ability previously restricted to characters, not their Gear). In Sonic Riders, bikes must first be unlocked by completing the Heroes Story Mode before they can be bought and used, much like skates. Dr. Eggman is the only character who uses a bike as his "starting Gear". Every character can use bikes except Ulala, the E-10000 robots, who can only ride boards, and the SCR robots, who use Wheels.

Air Ride
Air Ride Gear was introduced in Zero Gravity. Air Ride Gear is similar in shape to the Greek letter Psi (Ψ), and is rode by kneeling or lying down on the Gear. Air Ride Gear allows the rider to fly until he or she loses to much momentum and falls (an ability previously restricted to characters, not their Gear). Air Ride Gear is available from the start and does not need to be unlocked. Every character can use Air Ride Gear except Dr. Eggman, who rides bikes (and wheels in Zero Gravity), and the SCR robots, who use Wheels.

Yacht
Yacht Gear was introduced in Zero Gravity. Despite the name, Yacht Gear is more reminiscent of windsurf boards than boats. Like Air Ride Gear, Yacht Gear allows the rider to fly until he or she loses momentum (an ability previously restricted to characters, not their Gear), and also allows the rider to draft or "slipstream" behind opponents, reducing drag and helping to increase speed. Every character can use Yacht Gear except Dr. Eggman, who rides bikes (and wheels in Zero Gravity), and the SCR robots, who use Wheels.

Wheels
Wheels were introduced in Zero Gravity. Wheels are the largest Extreme Gear, as they need to be tall enough for the rider to sit inside and pilot. Wheels are the only Gear in Zero Gravity with the ability to powerslide, which in Sonic Riders was available to all Gear but required extra air consumption. Every character can use wheels.

Miscellaneous
Extreme Gear comes in many different shapes and sizes, and many unorthodox Gear are present in both Sonic Riders games. In fact, the first Extreme Gear ever made is actually a carpet, similar to one a genie would use. Other unconventional Gears include a flying broomstick, a cloud, and even the Opa Opa spaceship. These Gear still belong to one of the six classes listed above.
