Reliable. Durable. Quieter Than Ever Before. Following the Saris direct drive smart trainer legacy, the H3 features the same reliably and durability as its predecessors. Includes the MP1 Infinity Motion Platform.

Each H3 is made from cast and machined aluminium sourced from America’s heartland. 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.
