Nothing can replace training on a road bike – but even without the wind in your hair, nothing comes close to the feeling of cycling like the Racer S bike trainer from Kettler, whose numerous training programs ensure a varied cardio workout. The riding experience is adapted to an outdoor road bike with chain drive. The Racer S uses a belt to transfer power, but in speed-dependent training mode, the magnetic brake system causes the resistance to increase briefly with each gear change, as if a chain were jumping from one sprocket to the next. In addition, the bike can also be used as an ergometer with a resistance range of 25 to 600 watts. The special road bike handlebars also feature shift levers that allow you to change gears without interruption.
