In Sonic Riders: Zero Gravity, Sonic takes on to futuristic-inspired tracks and travels as far as outer space to push the limits of speed even further. From illuminated highways in a bustling metropolis to the outer reaches of space, you will race at the speed of light on 16 dynamic courses. You can switch up your vehicles, even in mid-race, to best suit your racing style. Transformations include a hover board, motorcycle and futuristic hovercraft, plus multiple options for upgrading ensure that no two vehicles will be the same. Depending on the vehicle upgrade, hidden routes may be uncovered, such as gliding on the air at the bottom of a valley, or riding through thick walls. Now, whether the terrain is waterway, highway or jungle, the action never slows down!
