Video Cycling gives indoor training that extra dimension. Now Tacx has extended this concept to all indoor trainers. Video Cycling is a new and spectacular item for riders who have a trainer and a DVD player. The speed of the film is matched to the course. As you cycle, the film indicates the gear you should be in for climbing or descending. Gear shifting is manual. Video Cycling is also highly suitable for fitness centers during spinning workouts. For use with a TV DVD player, simply select your type of trainer use the on screen display to manually change the resistance. A countdown timer lets you know how much more suffering you will have!
