Features

The Saris H3 direct-drive smart trainer is the quietest smart trainer ever produced by Saris, emitting only 59 dB at 20 mph. Each H3 is constructed from cast and machined aluminum for strength and stability. Inside are meticulously calibrated components to measure power, speed, and cadence, along with a precision-balanced flywheel—all designed to handle 2000 watts and replicate a 20% uphill gradient.

Tested to withstand intense training, the H3's internal cooling system will keep the electromagnetic resistance system running – and accurate – long after your legs have weakened.

Precise training: power accuracy of +/- 2%. Controlled and consistent: electromagnetic resistance provides a measured workout every time. Direct-drive design: compatibility with the widest range of bikes and eliminates wheel slippage.

No external sensors required: measures speed, cadence, and power. Seamless integration: connects to indoor cycling apps with both ANT+ FE-C and Bluetooth FTMS standards. Noise level: 59 decibels at 20 mph.
