Why We Like The H3 Direct Drive Smart Trainer
When the weather sours and it’s time to take training indoors, the last thing we want to hear is the steady whirr of a trainer for three months. The H3 Direct Drive Smart Trainer is the quietest ever made by Saris, besting the already library-quiet H2. Less noise from the trainer means you can focus on the ride—or just catch the finer plot details of the latest binge-worthy TV show while grinding base miles.
If you’re taking a purist approach to training, the H3’s Bluetooth and ANT+ connectivity pairs readily to apps like Zwift, Rouvy, Trainer Road and others to get the most out of your indoor hours. Built-in cadence, speed, and power sensors eliminate the need for additional setup steps or widgets. The robust aluminum body and precision-balanced flywheel can withstand your punchiest workouts, with a maximum of 2000 watts and a maximum simulated grade of 20%. An intelligently designed internal cooling system keeps the H3 accurate through the toughest efforts.
