The Beat Boost's icon takes the form of several green musical notes that possess a green aura and leave a lightning bolt of a trail. In gameplay, this power-up becomes a green aura around the user while they emit red and light green streaks.
Once obtained, the player can utilize the Beat Boost by pressing its icon on the bottom of the HUD. When used, the Beat Boost will increase the speed of the user for a short amount of time. The duration of the Beat Boost is shown by the decreasing gauge on top of this power-up's icon on the bottom of the HUD whenever the Beat Boost is in effect. In addition, when switching lanes while the Beat Boost is in effect, the user will receive a fast, albeit brief burst of additional speed. Rival characters that make contact with the Beat Boost will take damage, causing them to lose Rings and slow down momentarily, and will also have their Item slots on the bottom of the HUD locked for a short time, thus temporarily preventing the player from using the power-ups stored in them. The Beat Boost will end prematurely if the user collides with an obstacle or otherwise takes damage while the Beat Boost is in effect.
The Beat Boost can also be upgraded by leveling the user up to level 2, 8 and 14 respectively. For each upgrade, the speed of the Beat Boost's speed boost will increase.
The Beat Boost's jingle is a short remixed version of "Team Chaotix".
