UK 'exergaming' company Instyle Fitness, is to launch Dogfight - a flight simulator that works in conjunction with a high-end recumbent exercise bike.

Users propel the plane by pedalling and control the simulator via spring-loaded handles, with environments including a harsh winter landscape, a tropical group of islands and a busy cityscape.

There is a choice of aircraft in which to undertake missions, and after an initial tutorial, riders can take part in airborne battles against other players in the gym.
