Reviews & Ratings for Garmin Tacx Flux S Smart Bike Trainer — 2 reviews — Page 1

Great smart trainer at a lower price point than the top shelf versions. I was having trouble connecting bluetooth until realizing I needed to use the Garmin Ant+ usb dongle with Windows 10, once installing the Ant+ connection has been perfect. It comes with a 30day Tacx trial, and a ~7day Zwift trial to try them out which is sweet. The Tacx app has hyper realistic terrain, direct correlation with changes in grade, and real pro road race courses in the EU. Zwift has lame graphics, but the sociological encouragement to ride hard with all the other people riding live on the app, and training programs/workouts which are great. The flywheel is a little light, however with race gearing of 11-23 cassette and 39-53 crank it is great for both ~12% climbs on Tacx courses, and rolling flats. Connectivity to the apps is simple, Zwift is automatic, however sometimes I have to toggle Bluetooth on/off for the trainer to connect to the Garmin app, definitely get the Ant+ antenna right off the bat (~29$ on Amazon). Excellent for staying in shape during winter

I got the trainer looking for a way to ride this winter. I used to go to the gym and teach spin but with the current conditions, I am going to stay home and workout this season. The Tacx Flux is a great smart trainer. Setup is easy and you can get by with just a few additional items: cassette for your bike, wheel block (not needed but helpful), ANT+ dongle for connecting to a MAC/PC and then a few apps on the MAC/PC and phone. I downloaded the Tacx app and also Zwift. After using both I like the smoothness of the flywheel, but would like it to be a little heavier. You can get that for paying a bit more on an upgraded trainer. The other issue I have is the rocking. I might need some sandbags for standing sprints to keep the legs stable and to prevent frame damage. I strongly suggest doing a 10 minute warmup and then calibration, with each software app you use. This will help you see more accurate readings. I was seeing very low wattage prior to the calibration.
