Tacx Flux 2 Smart Bicycle Trainer

Brand : Tacx

Code : T2980

As if it could be improved any more, the iconic Flux Smart has been upgraded to the Flux 2 Smart trainer. Compared to its predecessor, it is equipped with a bigger and stronger resistance unit and a heavier flywheel. This resulted in a wider simulation range, better ride feel and a more accurate power measurement.


The Flux 2 Smart is equipped with a bigger resistance unit compared to its predecessor, allowing for a wider simulation range. It is able to realistically simulate inclines up to 16% gradient.


A reliable, accurate and consistent power measurement is key to keep track of your performance and progress. This is exactly what the Flux 2 Smart is designed for. It measures your power accurately within 2.5%.


A stronger resistance unit in combination with a larger flywheel significantly improved the ride feel and responsiveness of the Flux 2 Smart. With these improvements, this Smart trainer replicates the experience of outdoor rides even better than before.


The Flux 2 Smart is designed to bring vibrations and noise levels to the absolte minimum. This resulted in a very silent flywheel equipped bike trainer.

  • Accurate - measures your power accurately within 2.5%
  • Silent - the most silent flywheel equipped bike trainer available
  • Smart Trainer - connect to popular training apps, like Zwift and Tacx
  • Simulation Range - realistically simulates inclines up to a 16% gradient
  • Spring - a strong trainer with a maximum sprint resistance of 2000 watts
  • Heavy Flywheel - a large 7.6kg flywheel ensures the best ride feel


By supplying the Flux 2 Smart with additional axle adapters, the axle compatibility significantly increased. This direct drive is compatible with 142x12mm and 148x12mm axles, straight out of the box.


The smart electronics of this bike trainer allow you to train stand alone, without any software. It follows a progressive power curve, and the resistance will increase progressively when you ride faster. The trainer precisely replicates riding on a flat road.


Intuitive LED lights provide a visual confirmation when the trainer is powered and connected to a device over ANT+ or Bluetooth.


Designed to withstand the most intense training sessions, this bike trainer is built to last. A large footprint ensures maximum stability and durable materials give the quality you would expect.
