Tacx smart trainers are setting the standard for interactive bike workouts. Their Flux S Smart bike trainer hits the sweet spot for riders who want a smooth, responsive, and accurate trainer, but may not need all the features of Tacx's top-of-the line models.
At the heart of the Flux S Smart is a hefty 7 kg flywheel that provides a smooth, road-like feel. Flux S Smart fits just about any road, tri, or mountain bike, handles power output up to 1500 watts, and replicates grades of up to 10%, and will progressively increase resistance when you pedal faster, replicating real-world riding. Power output is measured to within 3% accuracy, so you'll have a realistic look at how your training is progressing. And you won't bother the neighbors (or spouse) with late-night or early morning training sessions — the design damps down vibrations to keep noise at a minimum.
Connective and compatible
This smart trainer supports Bluetooth and ANT+, allowing connection to an array of compatible smartphones, tablets, laptops, bike computers, and sports watches. When you're ready to hit the virtual road, choose from a variety of Tacx workouts and high-quality films and get riding. Flux S Smart outputs power, cadence, and speed data, plus supports virtual training with Zwift, TrainerRoad, and all other popular training apps.
