Futuresport (1998) on Netflix

Plot summary

Futuresport blends basketball, baseball and hockey, and by 2025 it is the sport the whole planet follows. Players use hoverboards and rollerblades. The game began as a way for feuding gangs to settle disputes without bloodshed. Obike Fixx invented it, yet the attention has always gone to Tre Ramzey. The Hawaiian Islands are the prize in a dispute between the Pan-Pacific Commonwealth and the North American Alliance, and a gang led by Eric Sythe, the Hawaiian Liberation Organization, is terrorizing them. Ramzey, with Alex Torres, once his girlfriend, and Fixx, his former coach, must stop the two sides from going to war.
