Train with Confidence
The internal mechanics of the FLUX Smart trainer are redesigned in order to improve the ride feel and data measurement. The result is FLUX 2 Smart — 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. It measures your power accurately within 2.5%.
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. So this smart trainer is very well-equipped to simulate an accurate hill climb. And no matter how intense your workout, this bike trainer is built to last. A large footprint and durable materials ensure maximum stability.
Smooth and Silent
A stronger resistance unit in combination with a heavier 16.8 lb (7.6 kg) flywheel significantly improves the ride feel and responsiveness of FLUX 2 Smart. 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.
The trainer communicates via BLUETOOTH® Smart technology and ANT+® FE-C protocol, making it compatible with a number of popular training apps. So whether you want to ride a famous cycling ride in the Tacx software, take on the virtual worlds of Zwift or utilize other platforms such as TrainerRoad, this bike trainer lets you ride smarter than ever before. You can also 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. And it can be connected to multiple devices simultaneously, so you can enjoy the software and track your performance on your Garmin bike computer at the same time.
The FLUX 2 Smart trainer comes with additional axle adapters to significantly improve axle compatibility. This direct drive is compatible with 142×12 mm and 148×12 mm axles — right out of the box.

Enjoy your time in the saddle with 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.
