The Saris H3 direct drive smart trainer is the quietest smart trainer that Saris has produced putting out only 59db at 20mph. Each H3 is made from cast and machined aluminum for strength and stability. 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.
