The Flux is a compact and realistic interactive direct drive and is maintenance-free. The swift response of the Smart electronics and the 7 kg flywheel transmits the slightest fluctuations in resistance directly and accurately to your legs.
Of all the Tacx trainers, the Flux has the heaviest actual flywheel with an effect of 23 kg. 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.
Connect to Windows PC
Do you own a Flux Smart and are you looking to get more out of your trainings than the Tacx apps can provide? You can achieve this by connecting your trainer to your computer. That way, you can train using the Tacx Trainer Software 4, Advanced.
Instead of your tablet or smartphone, your computer is used to regulate your resistance and read out your performance data. For example, the computer software offers longer video’s in HD or Blu-Ray quality. While riding, the resistance on your rear wheel is adjusted automatically when the slope increases or decreases.
To connect the Flux Smart to your Windows computer, the Upgrade Smart is required. This package contains the Tacx Trainer software 4, Advanced, a control box to mount on your handlebar and the ANT+ Antenna.
The Flux Smart works with an electro brake. By placing magnets and electro magnets beside a rotating aluminium disc, eddy currents are created which generate an opposing magnetic field. In this way a non-contact, maintenance-free brake is realized that is also silent. Thanks to the electro brake a resistance can be set that you also experience on the road or in a climb.
When you are cycling in a virtual terrain or in a film you can get outside the range for which the brake is intended. To allow cyclists with a motor brake and cyclists with an electro brake to ride races against each other in Multiplayer, Tacx has developed the virtual speed. This concept translatesthe energy supplied into a certain speed, which can guarantee a fair contest. If this speed differs from the speed at which the rear wheel is running, the virtual speed will be shown on the screen in red.
Software and Apps
You may connect a Tacx Smart trainer to your smartphone, tablet or computer with ANT+ or Bluetooth® Smart in order to use Tacx software and apps, or that of others. You may also use it stand-alone, without linking the trainer to a device. This means you are completely free to choose the software you want for your indoor cycling workout.
With Tacx software and apps, you may regulate your training ride by heart rate, gradient and power, or you may pick a famous route or race. Besides that, you may compete with other riders online. The training options vary by application.
The Flux has an universal EDCO Multisys body that fits all Shimano and SRAM cassettes, and most Campagnolo cassettes. Whether it fits depends on the amount of cutouts inside the cassette.
Campagnolo cassettes with 8 cutouts won’t fit unfortunately.
