Rainbow

"The only gear with unlimited gear changes. This single gear can rule any terrain!"

- Game description in Sonic Riders: Zero Gravity.

The Rainbow (レインボー) is a Board type Extreme Gear that appeared in Sonic Riders: Zero Gravity. It can perform Gear Change an unlimited number of times.

Description
According to its profile, the Rainbow has the potential for unlimited Gear Changes, allowing it to work in any terrain. It can be purchased at the shop for 9,999 rings.

The Rainbow, like most other Board type Extreme Gears in Sonic Riders: Zero Gravity, has a distinct board-like shape, but is much thicker and smoother than the Board types in Sonic Riders. The central section of the Rainbow is a straight figure, with two circular cyan foot panels on the top and a black area between them. On the front it has the half of a large ring-shaped tube, with green exhaust ports on the back points, attached, and around the rear it has a rectangular curve. True to its name, the Rainbow is a very colorful Extreme Gear, possessing red, blue, green and yellow highlights on its front and on its rear curve, and a blue area on the foremost front.

Unlike most other Extreme Gears in Sonic Riders: Zero gravity, which can only perform Gear Change once for each Gear Part, the Rainbow allows the players to activate each of its Gear Parts an unlimited number of times. However, it cannot activate the same Gear Part twice in a row. Also, because the Rainbow's Gear Parts allows it to transform into either a Board type, an Air Ride type or a Bike type, which abilities together can handle any obstacles or access any shortcuts on the tracks, the Rainbow's ability allows it to handle any hazard during a race by switching to the type best suited to the situation.
