Enjoy immersive indoor training

Tacx smart trainers are setting the standard for interactive bike workouts. Their Flux S Smart bike trainer hits the sweet spot for riders who want a smooth, responsive, and accurate trainer, but may not need all the features of Tacx's top-of-the line models.

Smooth performance

At the heart of the Flux S Smart is a hefty 7 kg flywheel that provides a smooth, road-like feel. Flux S Smart fits just about any road, tri, or mountain bike, handles power output up to 1500 watts, and replicates grades of up to 10%, and will progressively increase resistance when you pedal faster, replicating real-world riding. Power output is measured to within 3% accuracy, so you'll have a realistic look at how your training is progressing. And you won't bother the neighbors (or spouse) with late-night or early morning training sessions — the design damps down vibrations to keep noise at a minimum.

Connective and compatible

This smart trainer supports Bluetooth and ANT+, allowing connection to an array of compatible smartphones, tablets, laptops, bike computers, and sports watches. When you're ready to hit the virtual road, choose from a variety of Tacx workouts and high-quality films and get riding. Flux S Smart outputs power, cadence, and speed data, plus supports virtual training with Zwift, TrainerRoad, and all other popular training apps.

Features

Overview: The Tacx Flux S Smart Trainer is an interactive, direct-drive trainer for use with most training bicycles. It works with many popular third-party training apps, including Zwift, Trainer Road, and Tacx. The trainer provides a realistic ride and feel, and can replicate inclines up to a 10% gradient. The Flux S Smart Trainer comes with a free 30-day subscription to Tacx Premium software.

Compatibility: The Flux S is suitable for use with race, triathlon, and mountain bikes with 142 x 12mm and 148 x 12mm rear axles. It works with racing bikes with a 130mm rear fork width, and mountain bikes with 135mm rear fork width (needed fill ring included). Adapters for other widths are available. Suitable gear cassettes include Shimano / SRAM 8-to-11 speed, Campagnolo, SRAM XD and XD-R body (all sold separately). It is not compatible with specialized SCS systems.

Smart Trainer: The Flux S Smart Trainer features Bluetooth Smart technology and ANT+ fitness equipment control to connect to your smartphone or tablet running your favorite training apps. Two LEDs on the side panel indicate wireless connection via Bluetooth and/or ANT+. It works with Tacx software, or other third party training apps such as Zwift and TrainerRoad. The fitness apps running on your devices can control the Flux S to simulate courses with flat runs and inclines up to 10%. You can also use the trainer in stand-alone mode, or "unconnected." The trainer accurately (within 3%) outputs your speed, cadence, and power data to your smartphone, tablet, or Garmin Edge bike computer or sports watch. With the optional Tacx ANT+ Antenna (sold separately), you can send the data directly to your computer via USB.

It has a footprint of 26.4" x 25.3" and stands 18.1" high. Its sturdy design lets you ride full-out and standing on the pedals. Vibration and noise levels are brought to the absolute minimum, so you can train without disturbing others.

Assembly: The Smart Trainer comes in two main pieces, the main body and front stabilizer legs, and requires assembly. A compatible gear cassette (not included), and eventually the bike, will need to be installed on the trainer body. All of the needed hardware is included in the box.
