Bike is an installable performance-enhancing component for Extreme Gears. Its actual appearance is unknown, though it is presented as an icon on the head-up display in the top-left corner of the game screen. Its icon is a yellow-colored circle with a black motorbike inscribed in it.
In the game, Bike is permanently installed into only certain Extreme Gears. When used, Bike changes the Extreme Gear physically into a Bike type Extreme Gear and receives its traits. This allows the player to smash through obstacles and barricades by riding into them without slowing down, while gaining Gravity Points for each obstacle destroyed.
In gameplay, Bike and its ability are disabled when starting a new race. To activate Bike, the player must press one of the following buttons after collecting a certain number of Rings:
