Smooth and Silent
At 15.4 lbs (7.0 kg), a heavy flywheel ensures a realistic ride feel and good responsiveness of FLUX S 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 S Smart trainer comes with additional axle adapters to significantly improve the axle compatibility. This direct drive is compatible with 142x12 mm and 148x12 mm axles — right out of the box.
