Cheaper and quieter than its predecessor, Saris claim the H3 puts out 59db at 20mph. That’s very quiet and better than some of its more expensive rivals. This was backed up road.cc’s review. They also commented on the realistic ride feel, excellent stability and the power accuracy.
The H3 only recently hit the market, so there are few user reviews out there. But the review from Bike Radar backs up the points made by road.cc. Stability is helped by the 9kg flywheel and overall performance is comparable to more expensive models from Tacx and Wahoo. Setup is easy and all frame types are accommodated. The only clear downside is the need to buy your own cassette.
Saris have produced a nice (if expensive) add-on : its MP1 motion platform. With a bike and unit mounted on, this offers side-to-side and forwards and backwards motion.
