According to its profile, the GP Tank can store Gravity Points faster than any other known Extreme Gear. It can be purchased at the shop for 6,700 Rings.
Like most other Wheel type Extreme Gear in Sonic Riders: Zero Gravity, the GP Tank resembles a monowheel. Its driver interface is colored brown, with red and black plates on the sides, a red and white back wheel with a wide rim, and what appear to lights arranged like rear-view mirrors extending from the front sides. It also has an orange ring field encircling the driver interface and the rider, which serves as the wheel of the GP Tank.
Abilities and traits
As a Wheel type Extreme Gear, the GP Tank allows it rider to crash through obstacles and barricades without slowing down, gaining Gravity Points for each destroyed obstacle. Additionally, it allows the user to make Slide Turns to get through sharp corners. However, the GP Tank has rather low stats and as a Wheel type, it cannot perform Gravity Control to the full extent as most other types of Extreme Gear.
