Direct drive trainer with smart electronics and 7 kg flywheel: the FLUX S Smart from TACX

The FLUX S’s redesigned internal mechanics have improved the driving experience and result in a reliable and consistent performance measurement. It measures your power accurately within 3%. Like the previous FLUX Smart, this trainer is designed to reduce vibration and noise to a minimum. This has resulted in the quietest flywheel-equipped trainer.

The FLUX S Smart connects wirelessly via ANT + (FE-C) and Bluetooth Smart so you can connect to your favorite applications like Tacx Apps and Zwift. The intelligent electronics of this bicycle trainer also allow you to train independently and without software connections. The resistance follows a progressive performance curve, corresponding to riding on a flat road. Acceleration means an increase in resistance.

Intuitive LEDs on the side of the FLUX S Smart indicate when the trainer is powered and connected to a device via ANT + or Bluetooth. With the Tacx Utility App, you can easily upgrade the FLUX S Smart firmware to the latest version, so you can always take advantage of the latest improvements and features.
