Tacx FLUX S Smart Turbo Trainer


Bringing intuitive, real-to-life rides to your indoor workout, this innovative Tacx smart trainer utilises its wireless connectivity to put you at the heart of virtual rides and give instant performance data to keep you at the top of your game.

The Flux S Direct Drive Smart Trainer is packed with the latest in modern indoor training innovations to keep your edge in the off-season or when the roads can’t be run. Bluetooth and ANT+(FE-C) connectivity is built into the unit and will sync to your smartphone or tablet, letting you relay your RPMs, BPMs and cadence to your device for immediate analysis. Using third-party apps such as the Tacx Desktop app and Zwift, you can also fully immerse yourself in VR rides, adding as realistic a feel to every run as possible. Alternatively, you can ride in stand-alone mode and burn through your own workout, without virtual assistance.
