The FLUX S Smart is an accessible direct drive trainer with full Smart functionality. By changing the external design of its predecessor, it gained a wider bike compatibility range whereby it’s now compatible with long cage derailleurs. The well balanced design ensures maximum stability when cycling in even the most explosive sprints. The internal mechanics of the FLUX S Smart are redesigned to improve the power measurement. Because of this, the trainer is reliable, accurate and consistent and calculates your power accurately within 3%. This is key to keep track of your performance and progress. The internal upgrade together with the heavy flywheel of 7 kg (15.4 lbs) improved the ride feel significantly. This direct drive trainer is designed to bring vibrations and noise levels to the absolute minimum, resulting in the most silent flywheel equipped bike trainer available. It comes with ANT+ (FE-C) and Bluetooth Smart technology, enabling you to connect to your favourite applications like the Tacx Desktop app and Zwift. The smart electronics of the FLUX S Smart also allow you to train stand alone, without any software connections. Using the Tacx Utility app you can easily update the firmware to the latest version, so you can always make use of the latest improvements and features.
