STAC Zero Wheel On Trainer
Truly "the world's quietest bike trainer" because nothing touches your tire! The Zero was smart (detecting power), but not interactive (responding to gradient changes, ERG mode). It was replaced by the Halcyon.

Easy to use and keep in a small space, very silent and light.
Light weight and most silent trainer from Edu Abreu September 9, 2020Â
++ VERY Quiet Good Starter Smart Trainer from crepen September 8, 2020Â
++ Affordable
+ Stores Easily
+ Easy setup and connectivity
-- Difficult to install bike (wheel weights)
++ EXCELLENTsupport from Stac in Kitchener. Have not dealt with them since sale to 4iiii.
Once this trainer was dialed in it worked fine, and it was nice that it was low tech. I had no real concerns with the numbers it spit out or the performance. But between the wheel weights and everything else it took far too long to get it to a point where it was working well. Fancier trainers are basically just plug and play, and that definitely wasn't the case here.
