JETBLACK S1 MAGNETIC BIKE TRAINER
Magnetic resistance
The JetBlack Magnetic resistance system has a very smooth linear road like feel. Resistance is added by moving magnets adding resistance to our spinning disk. Depending on the model this is activated in different ways, either set resistance or manually changed with levers. With the support of our JetBlack weighted Flywheels, magnetic training has become very smooth and accurate. The resistance is changed by moving magnets. Either you set the resistance statically or change it via lever during the workout. With the support of our Flywheels, adjusting the magnets is very smooth and precise.
The cooling of the S1 is designed so that the measured values are precise and remain so during training. An optimal supply of air through a large housing cover ensures the ideal heat exchange. An optimal supply of air through a large housing cover ensures the ideal heat exchange.
