Roll Bounce (2005)

Xavier (Bow Wow), a teenage boy in Chicago, struggles with the loss of his mother and turns to roller skating as a way to deal with his angst. He and his friends are the stars of the skating rink they frequent, but this is about to change. When it closes down, they have no choice but to try out a more upscale spot, the Sweetwater Roller Rink. There, they enroll in a skating contest, and have to prove themselves to the reigning champions, headed by a skater named Sweetness.
