I enjoy using my smart trainer to mix up my workouts with virtual rides and structured training plans. The Garmin Tacx Flux S is compatible with the best indoor training apps, such as Zwift, BKOOL, and Rouvy.

Key features that make it the overall selection in the best smart indoor trainer guide are the smooth and silent performance, designed to keep vibration and noise levels to the absolute minimum, meaning you can ride whenever you want without disturbing household members or neighbours.

The Tacx Flux S also has a superbly realistic ride feel. Up to 10% incline simulation mimics real-world conditions, giving you a truly immersive experience—whether you’re climbing a hill or tackling a flat sprint. It can handle your most explosive sprints, up to 1,500 watts.

It's worth noting that the Tacx Flux S does not include a cassette, and you'll need to purchase one separately; however, with the savings made here, it's easy to stomach the extra cost.
