This VirtuReal Cycling software, in combination with a Praxtour bike, offers you the most realistic indoor cycling experience! The software is intended for the Course, Cruise and CtR Bikes and is equipped with Active Resistance. As a result, you feel the resistance associated with a climb or descent. By changing gears, you determine the gravity and your speed, and with your cycling speed, you determine how quickly the route film is played. Levels are therefore adjustable, from realistically tough to almost resistance-free.
