Flux S Smart Direct Drive Trainer

Though it doesn't boast the eye-popping specs of Tacx's Flux 2 and Neo 2 models, the Flux S Smart Direct Drive Trainer has all the capabilities that most cyclists will require for off-season training. Its watts ceiling, simulated incline, and accuracy are all lower than the more expensive models listed above, but it's still able to reproduce pretty much any conditions you could want. It tops off at 10% inclines, but climbs like Alpe d'Huez do, too, with the famed ascent only hitting 11% for a kilometer or so. The Flux S also provides up to 1,500 watts of resistance, which is admittedly lower than the Flux 2 (2,000 watts) and Neo 2 (2,200 watts), but still more than the 1,200 watts it took for Greipel to attack the field at the 2016 edition of Flanders.

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's own software to heavy hitters like Zwift, TrainerRoad, Sufferfest, and Strava. If you're not into the social or virtual training modes, though, 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 set-up required.

  • An indoor trainer that's both smart and accessible
  • Resistance unit ranks among the industry's quietest

I purchased at Flux S believing it would be an upgrade over my Kinetic fluid trainer and power meter setup that I had been using on Zwift. What is not clearly stated in advance is that the Flux S is absolutely NOT a "smart" trainer in the sense that it can connect to Zwift and allow the app to control its resistance. It has only one level of resistance, the same as any basic fluid or magnetic resistance trainer. The trainer connects to the proprietary Tacx Training application and gives accurate power numbers, so it's mechanically as it should be. I will be selling this on at a loss, however, and saving up to buy a Kickr as I enjoy indoor training and want the added value of variable resistance controlled by an app. I should have known that there wouldn't be an actual smart trainer for sale for less than $800. They need to update how they market this to consumers, however, as it is deceptively sold as being a smart trainer when it is only a dumb trainer with a heavier flywheel.

Everything I am reading says it can. Is something not pairing right with your machine?

Positive First Impressions

Familiarity:
I've used it once or twice and have initial impressions

After a second winter on the Kickr Snap, I decided to splurge on a direct-drive trainer, and I decided to look into Tacx's take on entry level wheel-off units. After the first couple of rides, I'm impressed. Solid build quality, relatively quiet operation, and helpful startup manual make for a win in my book. Look for an in depth review soon! Important note, Tacx does not include a thru-axle adapter. Check out item TAC002S to get your disc-brake equipped bike all set up!
