Testing this by setting it up in a bedroom produced a noise no more disruptive than a dishwasher heard through several closed doors.įor more involved training, Tacx has enabled the Flux to be compatible not only with its own proprietary training software but also with third party software such as Trainer Road and Zwift. It doesn’t feel quite so natural and ‘bike-like’ as the Neo or Wahoo Kickr due to the lack of motor driven freewheeling capability, but is certainly better than most high end wheel driven trainers.Īs with most other direct drive trainers, the Flux produces very minimal noise, even during sustained hard efforts. The Tacx Flux Smart can be adjusted to apply resistances equal to a 10% climb which is good for most hill training but lacks the 25% capability of the Neo for true mountain goat wannabees. The figures were always within the +/- 5% stated by Tacx, albeit a little low on most occasions. > Turbo trainers: a complete buyer's guide (video)Īdjusting power manually results in noticeable increases in resistance that read similarly to measurements recorded using different power meters. In comparison to a wheel driven trainer, powerful starting efforts rarely feel like they are overloading the motor and the feedback is instantaneous. Resistance is consistently delivered and feels silky smooth through the pedals. If this is important to you, the Flux can be connected to a Garmin or other ANT+/Bluetooth headunit to store data.īut it is pedalling where the Flux really shows the benefits of direct drive turbos and why they are becoming the future of indoor training. The only downside to the app is workouts cannot be synced directly to Training Peaks or Strava. > Zwift vs Peloton: which is best for your at-home workouts?

Through your smartphone and via Bluetooth you are able to record training sessions and manually control Slope and Power settings. To start accessing the features of the Flux, the minimum that is required is the Tacx Training app.
Whilst these figures are lower than the stated capabilities of the more expensive Neo, they are more than sufficient to cover the requirements of all but the most powerful riders out there. The Flux is capable of delivering up to 1500 watts of resistance for sprint sessions and can consistently hold up to 850 watts for a minute and up to 450 watts for a 20 minute period. This means that a power source needs to be available to run the unit properly. Like the majority of Smart trainers, the Tacx Flux Smart relies on electromagnets to adjust resistance.
