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.

Amazing trainer
- Familiarity:
- I've used it several times
This was super simple to set up. Les than 15 minutes from opening the box to being ready to ride. Extremely quiet and smooth the loudest part is just the chain.

only half good, got to be a pro bike mechanic to u
I have spent hours getting things to work, i used the same cassette the bike is on and the gears were off by 2, then i get that set all but the easiest gear no problem, finally got it working. now the front derailuer isn't putting the chain up to the big ring. You literally got to be a pro bike mechanic to get this to work and to stay working. Other than that, the zwift is awesome and when it works it's great---but it really is too cumbersome and i am sorry i bought it.

Not up to Garmin Standards
I have been using a Wahoo Kickr core for 3 yrs and decided to try the Tacx as I am a Garmin fan. It’s been a train wreck. My first unit was unresponsive, software issues. Garmin was great about replacing the unit. Their are great on support, they try hard. The replacement is better but not by much. Very poor response to grade changes ( I have used both the Garmin app and Zwift). It’s also totally inaccurate in terms of translating cadence, watts to speeds. The difference between the Tacx and Kickr is startling. I know from road riding that the Kickr is very accurate to real riding in terms of the power/gear/cadence you need on flat grade or up and down hill. The Tacx is off by at least 30% and totally off on grades up and down, especially bad on the downhills. I hope to be able to exchange this dog for a higher model and give Garmin one more shot
