Tacx Flux 2 Smart Trainer Review

The FLUX 2 Smart is equipped with a stronger resistance unit and a heavier flywheel to increase the maximum resistance to 2000 Watts.By positioning the additional weight of the flywheel strategically, the FLUX 2 Smart gained a higher mass inertia. This improves the ride feel significantly and makes every pedal stroke very smooth. By supplying the FLUX 2 Smart with extra axle adapters, the axle compatibility significantly increased. The FLUX 2 Smart is compatible with 142x12mm and 148x12mm, straight out of the box. Just like the internal structure, also the exterior of the FLUX 2 Smart has been redesigned completely. By creating more space for the derailleur cage, it is also compatible with long cage derailleurs. The internal mechanics of the FLUX 2 are redesigned to improve the ride feel and the power measurement. A reliable, accurate and consistent power measurement is key to keep track of your performance and progress. This is exactly what the FLUX 2 Smart is designed for, measuring your power accurately within a 2.5% range. Intuitive LED’s on the side of the FLUX 2 Smart show when the trainer is powered and connected to a device over ANT+ or Bluetooth. The smart electronics of the FLUX 2 Smart allow you to train stand alone, without any software connections. The resistance follows a progressive power curve, in accordance with cycling on a flat road. Speeding up means an increase of resistance. With the Tacx Utility app you can easily update the firmware of the FLUX 2 Smart to the latest version, so you can always make use of the latest improvements and features. You’ll get notified when an update is available.
