Why We Like The Tacx Flux S Smart Direct Drive Trainer
The Flux S Smart Direct Drive Trainer has all the capabilities most cyclists will require for off-season training. Its watts ceiling, simulated incline, and accuracy are lower than the more expensive models, but it reproduces nearly any conditions we could want. It tops off at 10% inclines, but real-world climbs like Alpe d'Huez do, too, so it's still more than enough to get the job done for most riders.
The Flux S also features all the functionality you'd expect from a smart trainer, including ANT+ and Bluetooth connectivity to apps ranging from Tacx to heavy hitters like Zwift, TrainerRoad, Sufferfest, and Strava. If you're not into the social or virtual training modes, the Flux S is smart enough to function in a vacuum. When used without a device and training app, the Flux S provides a progressive resistance curve to match the effort you're putting out and mimic the experience of riding on a flat road—no additional software or setup required.

Not so quiet at certain levels

- I've put it through the wringer
This is overall an okay trainer, but when using it at medium intensity there is a resonant frequency that causes my bike to rattle, and annoys my downstairs neighbors. I have to amp it up and maintain a higher than comfortable cadence to get it to stop. I have been through countless conversations and videos with Tacx support, and at one point they sent a replacement, but the replacement was far more defective than my unit and was producing knocking noises. Had I known my warranty was essentially worthless under these circumstances, I never would have purchased this. As such I will be going with a different brand next time.

Great!

Had this for about a month, and so far so good. I went with the gut and decided against any other smart trainer since Tacx is known for their turbos. Been riding nearly everyday on this. Price is definitely worth the return on investment. I?ve ridden rollers and the standard fluid trainers, but direct mount is out of this world. Highly recommend to anyone who is genially motivated to train inside.
