ACCURATE AND RELIABLE

This trainer is redesigned to let you track your performance and progress with reliable, consistent measurements. That includes power, speed and cadence, measured accurately within 2.5%.

READY TO SPRINT

The well-balanced design and large footprint of the FLUX 2 Smart trainer ensures maximum stability, even during the most explosive sprints, up to 2,000 watts.

CLIMB HIGHER

Get the most out of your intense workouts by training on realistically simulated inclines up to a 16% gradient.

A MORE REALISTIC RIDE

At 7.6 kg, a heavy flywheel ensures a realistic ride feel and good responsiveness.

SMOOTH AND SILENT

This direct-drive trainer is designed to bring vibration and noise levels to the absolute minimum, resulting in one of the most silent flywheel-equipped bike trainers available.

IMPROVED COMPATIBILITY

The trainer comes with additional axle adapters to significantly improve the axle compatibility. It is compatible with 142x12 mm and 148x12 mm axles — right out of the box.

A remarkably smart trainer.

HIGHLY COMPATIBLE

The FLUX 2 Smart trainer communicates via BLUETOOTH^® Smart technology and ANT+^® FE-C protocol, so it works with a number of popular training apps such as TrainerRoad and Zwift.

ABLE TO STAND ALONE

You can opt to use the trainer in stand-alone mode. When not connected, it will simulate a flat road; the faster you ride, the higher the resistance.

DEVICE COMPATIBILITY

Connect FLUX 2 Smart to multiple devices simultaneously, so you can enjoy Tacx software and track your performance on your Garmin bike computer at the same time.

TACX TRAINING SOFTWARE

Enjoy a library filled with more than 100 high-quality, real-life videos that let you experience the rush of riding the steep hills of the Alps or the cobblestone roads of Milan.
