FLUX S Smart is the ideal indoor training companion made to help you sweat while cycling with your favorite apps. Keep track of your performance and progress with reliable, consistent measurements. That includes power, speed and cadence, measured accurately within 3%. The well-balanced design and large footprint of the FLUX S Smart trainer ensures maximum stability, even during the most explosive sprints, up to 1,500 watts. Get the most out of your intense workouts by training on realistically simulated inclines up to a 10% gradient. You can opt to use the trainer in stand-alone mode. When not connected, it will simulate a flat road; the faster you ride, the higher the resistance.
