Flux S Smart Trainer Information

When winter rolls around, the hardcore cyclists will do anything they can to keep training. The Tacx Flux S offers high level indoor training on your favorite bike for a lower price than some of the other advanced trainers. The Flux S is quiet, accurate, durable, and has a realistic ride feel that is hard to find off the road. This trainer accurately mimics virtual routes or flat roads and gives you an accurate feel of power and difficulty on its own, without any software needed. Compatible with all your favorite cycling apps, the Tacx Flux S helps you improve through the most unrideable days of the year.

Like all Tacx trainers, the Flux S is extremely accurate. It tracks power accurately to within 3 percent and also tracks speed and cadence without the need of any additional sensors. This trainer can handle the power of a sprinter thanks to its ability to provide up to 1,500 watts of sprint resistance. Despite all the power it is able to handle, it dampens vibrations to remain virtually silent. The Flux S can also simulate the perfect ride feel, able to recreate gradients of up to 10 percent. A heavy 7 kilogram flywheel also ensures the best ride feel. A large and stable base will keep you feeling solid from the start of the ride to the end. The Tacx Flux S keeps your ride feeling legit from the comfort of your own home.

As a smart trainer, the Tacx Flux S can connect to all of your favorite apps like Zwift and Tacx. With the Tacx Cycling software, you can explore the world’s most famous cycling routes and challenge your friends on GPS workouts. It also tracks all of your data and progress which can be uploaded to Strava. The trainer has Bluetooth and ANT+ compatibility. These connections are confirmed by the LED lights on the side of the trainer. To customize your trainer, you can connect your favorite cycling computer or watch to display your data as you ride, mimicking the same setup you have on the road. The Tacx Flux S is a truly advanced indoor trainer for a very reasonable price.
