When it comes to indoor bike trainers, the most frequently asked question is: How quiet are they? Our team in Madison, Wisconsin, took this to heart and set out to build a trainer so quiet that the only sound you hear is your breath. The result? A smart trainer with direct drive that offers 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. Staying true to the legacy of the Saris Smart Trainer with direct drive, the H3 provides the same reliability and durability as its predecessors. Inside, you'll find components that have been carefully calibrated to measure power, speed, and cadence, as well as a precision-balanced flywheel—all built to handle 2000 watts and replicate a 20% incline. The H3's internal cooling system has been tested to withstand intense training, keeping the electromagnetic resistance system functional and accurate long after your legs have given out.
