H3 Trainer in action

Reliable. Durable. Quieter Than Ever Before.

H3 Direct Drive Smart Trainer, Train Smarter!

When it comes to indoor bike trainers, the most frequently asked question is: how quiet is it? Taking this to heart, our Madison, Wisconsin-based team put this query under the microscope and set a goal to build a trainer so quiet, that the only sound is that of your drive train.

The result? A direct drive smart trainer that touts a sound specification of 59 decibels at 20 mph. In other words, the H3 is five times quieter than previous generations, making it the quietest smart trainer to ever leave our doors.

H3 Direct Drive Training Features

  • Quieter Than Ever: all new drive system shaves decibels off previous generations
  • Direct Drive Design: widest bike compatibility and eliminates wheel slips
  • No External Sensors Required: measures speed, cadence and power
H3 Smart Trainer climb

Take training to another level!

Encased inside are components meticulously calibrated to measure power, speed and cadence, as well as a precision-balanced flywheel - all built to handle 2000 watts and replicate a 20% climbing grade.

Smooth, quiet, easy to install. It comes with a 30-day free trial of Zwift and a 30-day free trial of Rouvy. I loved this because I can try them both and decide which one I like more. It comes with a Front Wheel Riser Block but I bought another one because I founded that one very thin.
