Energy cannot be created or destroyed.
But on the road, within the chaotic revolutions,
Suddenly, seemingly, it appears like a jolt.
Flowing through tight corners,
And reverberating down dirty streets.
Bouncing off the walls it forms a rhythm,
Fueled by blood, sweat, and tears.
A feedback loop that charges through the pack,
So there’s always enough left for
One. More. Push.
This is Pulse of Speed.
