i bought a couple of cheaper bikes that i returned as they were terrible. Found these and they seemed reasonably priced. In use, they are very good. Plenty of resistance if you want it. Super quiet and smooth operation. Nice and solid.My only negative comments are, one, that the handlebars on both units are not exactly perpendicular to the bike frame. I will come up with a way to fasten them in a way that fixes that (probably insert a small shim) when I get around to it. And secondly, the display is not backlit, so depending on the brightness of the room it can be a little hard to see.Id buy again though.
