H3 Direct Drive Smart - Reliable. Durable. Quieter Than Ever Before.
The H3 is a Smart Trainer with direct drive and very low noise level (59 decibels at 32 km/h). The trainer is made from cast and machined aluminum. 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.
