The Tacx Vortex Smart combines interactive smart technology with the convenience of a fold-down trainer and a very good price. It’s easy to set up and use, with a steady feel and instant changes in virtual gradient resistance.

Tacx Vortex Smart set up and ride impressions
The Vortex Smart is easy to set up, especially once you have adjusted the axle clamp for your bike’s width. From there, you just flip the blue lever open and shut to get your bike in and out, and do the same with the blue paddle for the tire roller.
The Tacx app can be used for training, but I would recommend that you use it for calibration and then use your favorite app.
For a wheel-on smart trainer with a relatively light (1.6kg) flywheel, the Vortex Smart has a good feel, and it responds quickly and smoothly to resistance changes.
The fold-out legs are as stable as any trainer’s with a similar design.
Tacx Vortex Smart power comparisons
I found the Vortex’s power readings to be consistent, but also well above ( 12%) the averages of Pioneer and Garmin Vector 3 power meters that I tested it against concurrently.
As with the Wahoo Snap wheel-on smart trainer, the Vortex Smart has a slight delay in measurement for accelerations. This isn’t a terrible thing, but something to be mindful of if you are using the trainer for virtual group rides or races on Zwift.
Tacx Vortex Smart verdict
Tacx makes many trainers, and the Vortex Smart is a well-priced, easy-to-use option for a wheel-on smart trainer.
It is noisy at high power, and the power reads a little high, especially at lower outputs, but the responsiveness to apps/software is great and the unit is easy to live with.
