The Garmin Tacx® FLUX S Smart Trainer Checks all the boxes! Are you looking for a smart direct-drive trainer? FLUX S Smart is the ideal indoor training companion — made to help you sweat while cycling with your favorite apps.

  • You care a lot. So we measure your data to within 3% accuracy.
  • Go ahead and launch into full beast mode. This trainer is extra quiet.
  • Climb that leaderboard with your favorite apps, including Zwift and Tacx.
  • Feel the burn. Simulated inclines can withstand your hardest sprints.
  • Ride full out or standing on the pedals. This trainer can take it.


  • ACCURATE AND RELIABLE: Keep track of your performance and progress with reliable, consistent measurements. That includes power, speed and cadence, measured accurately within 3%.
  • READY TO SPRINT: The well-balanced design and large footprint of the FLUX S Smart trainer ensures maximum stability, even during the most explosive sprints, up to 1,500 watts.
  • CLIMB HIGHER: Get the most out of your intense workouts by training on realistically simulated inclines up to a 10% gradient.
  • A MORE REALISTIC RIDE: At 15.4 lbs (7.0 kg), a heavy flywheel ensures a realistic ride feel and good responsiveness.
  • SMOOTH AND SILENT: This direct-drive trainer is designed to bring vibration and noise levels to the absolute minimum, resulting in one of the most silent flywheel-equipped bike trainers available.


  • HIGHLY COMPATIBLE: BLUETOOTH® Smart technology and ANT+® FE-C protocol, so it works with a number of popular training apps such as TrainerRoad and Zwift.
  • ABLE TO STAND ALONE: You can 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.
  • DEVICE COMPATIBILITY: Connect FLUX S Smart to multiple devices simultaneously, so you can enjoy Tacx software and track your performance on your Garmin bike computer at the same time.
  • TACX TRAINING™ SOFTWARE: Enjoy 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.
  • TACX TRAINING™ PLANS: Take advantage of structured training plans, designed for your fitness level to help you meet your goals. Race live opponents, upload GPS data, ride with 3-D maps and more.
