The NEO Smart is the most powerful and silent indoor trainer to date. It is the only real direct drive as it does not contain any physical transmission like a roller or belt. The NEO is also the only indoor trainer that can simulate different types of road surfaces. Experience the feeling of riding on cobblestones, gravel and off road, all while you are indoors. You feel the vibrations of the road surface in your legs, exactly the way it would feel outdoors. This entirely new feature is unique to the NEO and can be used with some Tacx Films, virtual worlds and Zwift.
