Everything You Need to Train Smarter, Harder & Quieter
Joining the virtual training world can be overwhelming. That’s why we’ve built this do-it-all package to take all the guesswork so you can simply connect and ride. With this bundle your H3 smart direct drive trainer will come with a pre-installed 11-speed cassette, as well as all the accessories needed to pair to your favorite indoor cycling app.
Unsure which app is right for you? We’ve got you covered there too with the included 1-month subscription to ROUVY, Zwift, and TrainerRoad.
And when it comes to the trainer itself, the H3 features the same reliability and durability as its predecessors – only quieter. At 20 mph and just 59 decibels, the H3 is five times quieter than previous generations, making it the quietest smart trainer to ever leave our doors.
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.
