The FLUX 2 Smart gives your bike an extensive simulation range, allowing you to train in your own living room and maintain your fitness, whatever the weather. This smart bike trainer can realistically simulate inclines of up to 16%, so you feel like you're cycling on a real track or road. The FLUX 2 Smart records your performance with an accuracy of up to 2.5% and challenges you with a sprint resistance of up to 2,000 watts.

Optimal training for all fitness levels

You can use the FLUX 2 Smart with or without software. You can either connect it to apps such as Zwift or Tacx's own app, or use the trainer's autonomous, intelligent electronics which will progressively increase the resistance during your ride without any need to use a controlling app. With the Tacx FLUX 2 Smart, you get your money's worth in every performance class.
