All Expresso Bikes offer riders use a Pacer to gauge their progress or actively compete in real-time against virtual competitors, friends or members within the same fitness facility. The Expresso Fitness S2u makes you feel more like you are playing a video game than exercising. Captivated by stunning graphics, realistic rides and in-ride games on over 30 virtual courses, you will quickly forget you are exercising. It's cardio, only way cooler.
