The Kick Dash, also known as the Air Boost, is a move that first appeared in Sonic Riders. It is a racing maneuver used by racers riding on Extreme Gear who use Air to give themselves a burst of speed.
When performing the Kick Dash, the user releases a burst of air from the rear of his/her Extreme Gear, resulting in the user and his/her Extreme Gear being propelled forward at high speed.
In gameplay, the Kick Dash gives the player a momentary increase in speed, enabling the player to reach top speeds almost immediately. To perform the Kick Dash in gameplay, the players must have Air in their Air Tank. However, the move uses considerable amount of Air in the Air Tank, the amount of which depends on the Extreme Gear, so it should only be used sparingly. In addition, the Air Boost can also activate the special abilities of some Extreme Gears.
The move first appeared in Sonic Riders, where it is called the Air Boost. To perform the Air Boost in gameplay, the player must press the action button (/ on the Xbox, / on the Nintendo GameCube, or / on the PlayStation 2) while having a sufficient amount of Air remaining in the Air Tank.
In addition to increasing speed, the Air Boost can be used to attack opponents in front of the player, temporarily disorienting them while gaining some Air.
Sonic Free Riders
The move reappeared in Sonic Free Riders, where it is renamed Kick Dash. Due to the Kinect controls, to perform Kick Dash in gameplay, the player has to kick their back leg out if riding a Board type Extreme Gear, or kick their right leg out if riding a Bike type Extreme Gear while having Air remaining in the Air Gauge. Unlike the Air Boost in Sonic Riders, the Kick Dash can be performed regardless of how much Air is remaining in the Air Gauge.
