    Compatible with Zwift

    When we combined Smart technology with a direct drive trainer, the indoor training experience was elevated to a totally new experience level. The global response to the NEO has been phenomenal and this has fuelled our desire to develop a range of trainers that will make this training experience available to a larger group of cycling enthusiasts. The result is highly functional, capable and intuitive device with its own distinctive silhouette.

    Fully Interactive

    The FLUX is a fully interactive Smart trainer, that connects you to all your favourite apps. Hosting the dual band ANT+ FE-C and Bluetooth technology, it communicates with and can be controlled by any device of your choice. The responsive Smart electronics make sure that the smallest fluctuation in power settings is converted into an alteration in resistance, making sure that each watt is transferred accurately to your body.

    8 strong electro magnets

    The desire to create an accessible direct drive has meant designing a whole new product. The best riders are able to produce 850 watts for 1 minute, or maintain 450 watts for 20 minutes. The FLUX has been designed to deliver exactly these power values and is thus more than capable of fulfilling the needs of the average cyclist. Driven by 8 strong electro magnets the FLUX is even able to generate a stunning 1500 watts during a sprint. The trainer feels very smooth due to its 7 kilogram flywheel. The FLUX has a simple calibration process ensuring tension and power measurements, accurate within 5%, whilst the products internal structure has been tuned to simulate a true road feel.

    Compact design

    This inner structure has also meant developing a new outer design: a casing that covers and complements the product whilst honouring the looks of its bigger brother. Its compact design clearly differentiates the FLUX from other indoor trainers whilst subtly being a family member of the NEO, with the same stealth-like form language and durable, sophisticated finish.

    The FLUX has been designed to complement Tacx’s direct drive assortment beautifully and it can be seen as the most accessible interactive Smart direct drive trainer to date.

    The FLUX is a compact and realistic interactive direct drive and is maintenance-free. The swift response of the Smart electronics and the 7kg flywheel transmits the slightest fluctuations in resistance directly and accurately to your legs.

    Tacx heaviest flywheel

    Of all the Tacx trainers, the FLUX has the heaviest actual flywheel with an effect of 23kg. The greater the flywheel effect, the more realistic the cycling experience. It uses ANT+ and Bluetooth® Smart for communication and can therefore be connected wirelessly to smartphones and tablets. The ANT+ FE-C protocol enables you to train with Tacx apps as well as third-party apps such as Zwift and TrainerRoad. You can also train stand-alone; if you do not connect the FLUX, it will simulate a flat road.

    Two technologies combined

    With the FLUX we combined direct drive technology with an electro brake in order to offer an accessible Smart and interactive direct drive.

    • 1500Wpower
    • 10% max. slope

    Smart & fully connected

    • This trainer is connected wirelessly to smartphones and tablets and knows the ANT+ FE-C protocol, enabling you to train with Tacx apps as well as third-party apps like Zwift and TrainerRoad. You can also train stand-alone; if you do not connect the trainer, it will simulate a flat road.

    Big Flywheel

    The Flux offers the truest simulation of a pedal stroke as it is equipped with the heaviest flywheel to date.

    • 7kg flywheel

    Quiet operation

    The inner parts of the Flux are carefully selected to minimise sound levels.

    Automatic Calibration

    The set up of the Flux enables an easy, automatic calibration process to ensure high accuracy.

    • <3% accuracy

    Stable & Robust

    The FLUX has been designed to enable you to really push your limits, especially when standing on the pedals.

    • 670x650mm footprint

    Plug & play

    As the FLUX is a direct drive you simply remove your bike’s rear wheel and place it directly on the trainer, step on and start training.

    Connections revealed

    The FLUX shows when it is connected to the mains and to a device over ANT+ or Bluetooth by an LED light on the side.

    Compatible software

    Tacx Smart trainers use the Bluetooth Smart and ANT+ FE-C protocol for communication which allows them to be controlled by third-party software. The software receives the speed, cadence and power from the trainer and controls the brake. Click on more information for an explanation of the compatibility and functions of each software package.
