Parts Lock is a Gear Part that appears in Sonic Riders: Zero Gravity. It is an Extreme Gear component that grants Parts Lock to opponents.


Parts Lock 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 red-colored circle with a black Board type Extreme Gear, which has a 'X' across it, inscribed in it.


In the game, Parts Lock is permanently installed into only certain Extreme Gears. When used, Parts Lock grants the obstacle of the same name to all the opponents participating in the same race with the player, preventing them from activating their Gear Parts and using Gravity Control and Gravity Dive. Like when obtaining it from an Item Box, however, the effect of the Park Lock obstacle granted by the Parks Lock Gear Part only lasts for a limited time.

In gameplay, Parts Lock and its ability will be disabled when starting a new race. To activate Parts Lock, the player must press one of the following buttons after collecting a certain number of Rings:

PS2 Wii (remote) - sideways Wii (remote) - forward Wii (Nintendo GameCube Controller)

When activating Parts Lock, the player's Rings will be reduced accordingly by the number needed to enable it and the Extreme Gear is surrounded by an orange void, indicating that the Gear Part's ability is in effect. The following Extreme Gears come equipped with the Parts Lock:
