Reliable. Durable. Quieter Than Ever Before.

When it comes to indoor bike trainers, the most frequently asked question is: how quiet is it? Taking this to heart, Saris’ 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 Saris’ doors.

Following the Saris direct drive smart trainer legacy, the H3 features the same reliability and durability as its predecessors. 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.

Tested to withstand heavy training, the H3’s internal cooling system will keep the electromagnetic resistance system working – and accurate – long after your legs have given out.
