Make Every Workout Count!

What happens when you pair a speed sensor with the #1 selling bike trainer in the USA?

You get a combo that’s ready for any virtual – or non-virtual – training ride. It’s the ideal setup for budget-conscious athletes looking to join fun, virtual communities, like Rouvy and Zwift, without a traditional smart trainer.

Simply install the magnetless speed sensor on the rear wheel of your bike, mount your bike to the solid Fluid² trainer with our innovative clutch knob, connect to your indoor cycling app of choice via Bluetooth or ANT+ and voilà! - you’re ready to sweat.
