Tacx Flux S

The Flux is a compact and realistic interactive direct drive and is maintenance-free. The swift response of the Smart electronics and the 7 kg flywheel transmits the slightest fluctuations in resistance directly and accurately to your legs.

Of all the Tacx trainers, the Flux has the heaviest actual flywheel with an effect of 23 kg. The greater the flywheel effect, the more realistic the cycling experience. It uses ANT+ and Bluetooth® Smart for communication and can therefore be connected wirelessly to smartphones and tablets. The ANT+ FE-C protocol enables you to train with Tacx apps as well as third-party apps such as Zwift and TrainerRoad. You can also train stand-alone; if you do not connect the Flux, it will simulate a flat road.
