Saris Fluid² Indoor Trainer with Speed Sensor

Smooth. Quiet. Connected.

Get ready to power through your indoor training goals with the Saris Fluid², the #1 best-selling bike trainer in the USA—now smarter than ever. This budget-friendly setup comes with a magnetless speed sensor, making it easy to connect to popular indoor cycling apps like Zwift and Rouvy, so you can train smarter, ride longer, and stay motivated all year round.

Designed for cyclists who want a realistic road feel, the Fluid² features a progressive fluid resistance unit that responds naturally to your pedalling effort.
