Prayer of the Rollerboys(1991)

In the 21st Century, it's gonna take one man and his blades to save the world from another man...and HIS blades.

Griffin, a rollerblader in the not so distant future of an economically wrecked Los Angeles, races against time to save both his younger brother and the city from the fate dealt out by the fascist rollerblading street gang, the Rollerboys.
