The Saris H3 is a direct drive smart trainer that removes the rear wheel and runs your chain straight to a 20 lb flywheel. It measures speed, cadence and power itself, holds power accuracy to about +/- 2%, and simulates grades up to 20%. Owners consistently call it quiet and solid, and it works with Zwift and other apps over ANT+ FE-C and Bluetooth FTMS. It is a strong alternative to pricier flagship trainers, though you supply your own cassette and the unit is heavy to move.

The Saris H3 is a direct drive smart trainer. It measures speed, cadence and power without external sensors, with power accuracy of +/- 2%. It connects over dual ANT+ FE-C and Bluetooth FTMS and is Zwift certified.
The trainer produces 59 dB of noise at 20 mph, which is five times quieter than previous generations. It reaches a maximum power output of 2000 watts at 20 mph and simulates a climbing grade of up to 20%. A 20 lb precision-balanced flywheel and internal cooling keep data accurate during hard workouts.
The body is made of cast and machined aluminum. The legs fold for stability and storage, and the trainer has an integrated carrying handle and a built-in front wheel block.
