About the Tacx Flux 2

Improved indoor training

Tacx smart trainers just keep getting better. The Flux 2 Smart bike trainer builds on the smooth and responsive performance of the Flux S Smart with a beefed up flywheel and stronger resistance unit for more accurate power measurement, better ride feel, and a wider simulation range. It's a great choice for the rider who wants a high-performance smart trainer but doesn't need all the features of Tacx's top-of-the-line models.

Smooth performance

The hefty flywheel at the heart of the Flux 2 Smart handles power output of up to 2000 watts and replicates grades up to 16%, enough to let you take on the stiffest challenges from the comfort of your home. Flux 2 Smart fits just about any road, tri, or mountain bike, and will progressively increase resistance when you pedal faster, replicating real-world riding. Power output is measured to a 2.5% 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 2 Smart outputs power, cadence, and speed data, plus supports virtual training with Zwift, TrainerRoad, and all other popular training apps.

Product Research

Features

Overview: The Tacx Flux 2 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, replicating inclines up to a 16% gradient, and its near-silent direct drive lets you ride without disturbing others. Its sturdy design allows for riding at high intensities and standing on the pedals. The Flux 2 Smart Trainer comes with a free 30-day subscription to Tacx Premium software.

Compatibility: The Flux 2 is suitable for use with race, triathlon, and mountain bikes with 142 x 12mm and 148 x 12mm rear axles, Race 130mm, and MTB 135mm. Axle adapters are included for compatibility with a wide range of axles. 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 2 Smart Trainer features Bluetooth Smart technology and ANT+ FE-C 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 2 to simulate courses with flat runs and inclines up to 16%. You can also use the trainer in stand-alone mode, or "unconnected." The trainer accurately (within 2.5%) 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.

Construction: The Tacx Flux 2 is a heavy duty trainer with a 16.8 pound flywheel and an overall weight of 52 pounds. It is equipped with 8 permanent ferrite magnets and 8 electromagnets. It has a footprint of 26.250" x 25.125" and stands 18.250" 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. The Flux 2 is powered by standard household current (110-240V), and comes with a 6' AC power cord.
