SARIS H3 Direct Drive Smart Trainer

Reliable. Durable. Quieter than ever.

When it comes to indoor bike trainers, the most frequently asked question is: How quiet is it? Our Madison, Wisconsin-based team took that question to heart and set out to build a trainer so quiet that the only sound is that of the drive train. The result? A direct-drive smart trainer that has a noise level of 59 decibels at a speed of 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.

The H3 follows in the tradition of Saris' direct-drive smart trainers and features the same reliability and durability as its predecessors. Inside are carefully calibrated components to measure power, speed and cadence, and a precision-balanced flywheel - all rated for 2000 watts and a 20% incline. The H3's internal cooling system has been tested to withstand heavy training and ensures that the electromagnetic resistance system still works - and is accurate - long after your legs have given out.
