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.

    Mine lasted one ride....

    Doesn’t look as though the well documented problems have been fixed by Tacx. First ride saw belt slipping, internal rubbing noise & burning smell. Gone back but not heard anything yet so I’ve been without it for over a week with no indication of status. Avoid

    Tacx should be ashamed

    Tacx has the right idea with an affordable direct mount smart trainer but the quality is appalling, I’m on my second unit after the first one decided it didn’t like turning on. I joined the owners group on Facebook and the same issues appear Day after Day. Spend a little more and get something more reliable!

    Decent

    For the price I can't really knock the flux. As many of the reviews state a handle to pick the thing up would be useful but its a minor issue. It's no neo or kickr but then its half the price as does exactly what I need to get my training through the naff months.

    Beware. European plug supplied through Tredz

    I cannot fault the flux, it's transformed my indoor training with zwift. I love it! Unfortunately though Tredz seems to supply its flux units with a European plug rather than uk - disappointing having spent £600 then having to go and buy a converter to use it! Wiggle, cycle surgery and ribble all supply with UK plugs - I'd suggest you go there unless you have a spare converter.

    Great potential with serious issues

    After a wait of many months to receive my Flux I can say that it's got the potential to be a game changer in the mid-price turbo trainer market, but serious issues hinder it massively, it is a million miles from being a Kickr/Neo challenger. The responsiveness to increases in power put through the Flux is extremely laggy, taking approximately five seconds for the machine to recognise the additional force being generated by the user. This produces data that is inaccurate and hinders the unit with programmes such as Zwift, where your avatar responds to your effort levels. Tacx have improved this with a software update but it's still a significant problem. The most serous problem comes from the design itself. There have been well documented issues with the belt slipping from its mechanism, rubbing on the interior of the casing and shredding itself, unfortunately this is something I have come across, and whilst Tacx customer support have been outstanding, until they release some form of statement regarding the issue, what batches it affects, and what they plan to do about it, I would not recommend the Flux. A future recall of the units would not surprise me.

    Turbo Trainers Guide

     
     

    How do turbo trainers work?

    Most turbo trainers work by fixing to your bike frame with a clamp around the quick release skewer of your rear wheel. This puts your bike into a position where the rear tyre will sit on the turbo trainer’s roller drum. As you begin to pedal, your rear wheel spins and the roller drum turns.


    Types of resistance

    Wind resistance

    Wind/Fan

    Magnetic resistance

    Magnetic

    Fluid resistance

    Fluid

    Electromagnetic resistance

    Electromagnetic

    A great value choice if you’re looking for your first turbo trainer.

    When you pedal, the fan spins creating air resistance. Resistance is smooth and progressive for a life-like experience.

    Magnetic turbo trainers are the most common. They use a spinning metal disc which spins relative to magnetic discs to generate drag.

    Most will have multiple pre-set resistance settings you can choose to make the ride harder.

    You change resistance either by manually changing the setting on the turbo trainer or with the use of a remote positioned on your handlebar.

    Fluid turbo trainers offer very smooth, lifelike resistance by spinning a thick fluid within a sealed chamber.

    Fluid trainers offer progressive resistance, so the harder you pedal, the harder the resistance becomes, just like real-road riding conditions.

    Electromagnetic turbo trainers are becoming more popular.

    Just like magnetic turbo trainers, these use a magnetic field to generate drag on a metal disc. However, resistance can be changed wirelessly for use with apps and devices.

    These turbo trainers give you the greatest level of control over the exact resistance you want.

    • Low budget
    • Smooth progressive resistance

     

    • Multiple resistance settings to challenge yourself
    • Max resistance settings can be very high
    • Within budget for many
    • Quietest resistance offering. Perfect to keep the family happy

    What is a smart turbo trainer?

    Every big turbo trainer brand now has a range of smart turbo trainers. They are the new big thing in the indoor cycle training market. These turbos use electromagnetic resistance and can be synced wirelessly with ANT+ and/or Bluetooth Smart to your 3rd party training apps, devices, power meters and sensors. This connectivity can greatly enhance your training regime and open up fun virtual training apps to keep you motivated.

    Zwift, BKOOL and other training apps can automatically change the resistance of your turbo trainer opening up the possibility of sprint training, intervals and even simulate climbs of up to 20% gradients.

    You can also use apps to pre-load a set training plan to follow or plug-in GPS data and ride famous cycling routes from around world while viewing the route on your computer or smart T.V.


    Zwift virtual training app

    Zwift logo


    Zwift is powerful training app where you can challenge yourself against other real-world riders to a race in a 3D virtual environment. Zwift distinguishes itself from other training apps by offering a video game-like experience with immersive virtual worlds for you to ride in. As well as structured workouts, Zwift gives you the opportunity to join group rides with other riders of a similar ability and even compete in online races. It’s a great way to mix up your training and have a bit of fun.

    Your power is measured by the watts you produce, which is then used to move you forward through the 3D environment. Speed is also adjusted by your height, weight and even the road gradient for added realism. You can learn with our Zwift guide

    Zwift is compatible with a wide range of turbo trainers, indoor bikes and rollers with ANT+ or BLE enabled. Read our Zwift Compatibility guide for more information.


    What is a direct drive turbo trainer?

    Direct drive turbo trainers work in a different way to a traditional turbo trainer. Your bike is attached to the drive unit via the cassette, so you do away with the rear wheel entirely. This does mean it takes a bit longer to setup than a traditional turbo, but you get some useful benefits in return.

    1

    The flywheel is moved to a central position

    This offers a more lifelike feel compared to a traditional turbo where the flywheel is placed behind the rear wheel.

    2

    Precision performance metrics

    Most direct drive turbos are compatible with a range of power meters, sensors, apps and devices to let you track your performance data. With no rear wheel, there is no tyre slippage or roller drum tension to cause inconsistencies in your data.

    3

    Quiet operation

    Direct drive turbos are much quieter than a standard turbo trainer as there is no roller or tyre friction to create noise.

    4

    No tyre wear

    No rear wheel means no tyre. You don’t have to make that choice between wearing down your racing tyres or wrapping a spare onto your wheel to protect them.


    What accessories are available?

    Training mat

    Training mat

    A training mat will protect your floor from marks and damage, as well as sweat. These mats help prevent you skidding around when you’re really powering through and they will soak up some noise.

    Sweat towel

    Sweat towel

    Indoor cycle training will make you sweat. These small towels will cover your top tube to prevent damage and corrosion.

    Riser blocks

    Riser blocks

    With a standard turbo trainer, your rear wheel will be slightly raised, giving the feeling of descending. A riser block will lift your front wheel for a more realistic cycling position.
