Tacx FLUX 2 Smart Trainer

The award-winning FLUX Smart has now been upgraded to the new Tacx FLUX 2 Smart Trainer. Now featuring a bigger and stronger resistance unit and flywheel, the FLUX 2 allows for a wider simulation range, better ride feel and more accurate power measurement. In addition, the next-to-silent direct drive brings vibrations and noise levels to a minimum. The result is one of the most silent flywheel-equipped smart bike trainers on the market.

Of course the Tacx FLUX 2 features ANT+ and Bluetooth SMART compatibility which makes it compatible with all of the popular training apps such as Zwift, TrainerRoad and more. The trainer is also built tough. It can handle sprints of up to 2,000 watts, can simulate climbs up to a 16% incline and all while measuring your power within 2.5%!



Train with Confidence
The FLUX 2 Smart is designed to provide a reliable, accurate and consistent measurement of your power, speed and cadence, so you can keep track of your performance and progress.

Conquer Extreme Climbs
The well-balanced design of FLUX 2 Smart ensures maximum stability when cycling in even the most explosive sprints. It powers up to 2,000 watts, and you can train on realistically simulated inclines up to a 16% gradient, even at low speeds.

Smooth and Silent
A stronger resistance unit in combination with a heavier 16.8 lb. flywheel significantly improves the ride feel and responsiveness. This direct drive trainer is designed to bring vibrations and noise levels to the absolute minimum, resulting in one of the most silent flywheel-equipped bike trainers available.

Fully Connected
The trainer communicates via Bluetooth Smart technology and ANT+ protocol, making it compatible with a number of popular training apps such as Zwift, TrainerRoad and more.

Improved Compatibility
The FLUX 2 Smart trainer comes with additional axle adapters to significantly improve axle compatibility. This direct drive is compatible with 142 x 12 mm and 148 x 12 mm axles — right out of the box.
