Make Every Workout Count

Better health. Faster splits. More me-time. Whatever your goals may be, the Fluid² helps you get the most out of each indoor training ride.

The large, precision-balanced flywheel (with patented fan design) lets you easily customize each ride simply by shifting gears, just as you would outside. This design also helps keep your Fluid² working better – longer. And thanks to our built-to-last manufacturing process, the Fluid² can help you conquer one goal after the next.
