A solid indoor ride on your own bike

Garmin Tacx FLUX 2 Smart Bike Trainer

The Garmin Tacx FLUX 2 Smart Bike Trainer is a direct-drive bike trainer with a 7.6 kg flywheel and a bigger resistance unit that improve the ride feel. Power measurements read within 2.5%, which keeps your progress tracking reliable. Sprints reach 2,000 watts, simulated inclines climb to a 16% gradient, and the large footprint keeps the frame stable under hard efforts. It is one of the most silent flywheel-equipped bike trainers available. The cassette body is in the box and the cassette is not. Zwift, TrainerRoad and the Tacx Training app connect over Bluetooth and ANT+ FE-C.

The FLUX 2 is perfect for anyone looking for a solid, reliable indoor ride on their own bike. It is equipped with a bigger and stronger resistance unit and a heavier flywheel for an all-around better riding experience. The FLUX 2 is also extremely quiet, great for those riders who like to hop on the saddle late at night or early in the morning. Push your ride to the next level with the Tacx FLUX 2 Smart Bike Trainer.

Silent running
The FLUX 2 brings vibrations and noise levels to the absolute minimum, and the result is a very silent flywheel-equipped bike trainer.

Feel the flywheel

A stronger resistance unit working with a larger flywheel improves the ride feel and responsiveness of the FLUX 2, and the trainer better replicates the experience of outdoor rides. The 16.8 lb (7.6 kg) flywheel brings mass inertia of 68.8 lbs (31.2 kg).
