Jet Moto

Jet Moto (known as Jet Rider in Europe) is a 1996 racing video game developed by SingleTrac and published by Sony Computer Entertainment for the PlayStation video game console and PC. Developers chose fictional hovering bikes instead of wheeled motorcycles initially to resolve performance concerns. Other performance concerns led the team to develop two different physics systems--one for the player, and one for the 19 computer racers. (wikipedia)
