Garmin Tacx FLUX S Smart Trainer

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. Go ahead and launch into full beast mode. This trainer is extra quiet.

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. 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. 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.

Keep track of your performance and progress with reliable, consistent measurements. That includes power, speed and cadence, measured accurately within 3%. 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. Get the most out of your intense workouts by training on realistically simulated inclines up to a 10% gradient. At 15.4 lbs (7.0 kg), a heavy flywheel ensures a realistic ride feel and good responsiveness.

The FLUX S Smart trainer communicates via BLUETOOTH® Smart technology and ANT+® FE-C protocol, so it works with a number of popular training apps such as TrainerRoad and Zwift. 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. 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.

Note! Cassette not included.
