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. 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 7 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. It's fully connected, so you can train your way. HIGHLY COMPATIBLE FLUX S Smart 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. 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.
