Quiet Direct-Drive Training with Smart Control

Overview

The Tacx Flux S Smart Indoor Trainer is built for cyclists who want a reliable direct-drive trainer for structured indoor workouts. It connects with popular cycling apps, making it easy to train, ride virtual routes and stay consistent when outdoor riding is not possible.

Accurate Performance Tracking: This smart trainer measures power, speed and cadence with accuracy within 3%, helping you track progress with confidence. The consistent data makes it useful for interval sessions, endurance rides and regular indoor training plans.

Stable During Hard Efforts: The well-balanced design and large footprint keep the trainer steady, even during powerful sprint efforts. With support for sprints up to 1,500 watts, it gives strong riders the stability they need during high-intensity sessions.

Realistic Climbing Feel: The trainer can simulate gradients up to 10%, adding more realism to climbs and structured workouts. This helps make indoor riding more engaging while preparing your legs for outdoor hills and harder riding conditions.

The Tacx Flux S Smart Indoor Trainer is a smooth and silent direct-drive trainer made for accurate, stable and app-friendly indoor cycling sessions.
