- My first ride was on the Zwift Richmond course, really hammering away on the hill sections, and afterwards my wife complained to me that she could hear the trainer resonating downstairs. This was a real disappointment, as the main reason for buying the Neo was its lack of noise. However, when I was riding in normal trainer mode the next few times (0 gradient) at steady 200ish watts she told me she couldn’t hear a thing downstairs. So perhaps the tough hill sections (=high wattage) caused some additional structural vibration, who knows. I did, however, add extra rubber feet under the trainer after my first ride, so those might have made the difference. I still intend to do additional sound testing later.
I know it has only been a few days but wondering if you have any further insight…
I live on a second floor flat, and the quietness of the Neo is one of the things that is very attractive to me.

Unfortunately I’ve been really busy the last week, so haven’t been able to get int as many trainer workouts as I would have hoped. But I would have to say that my impression of the trainer seems to be getting more positive after each workout, and I can’t really see myself going back to a regular trainer anymore. While I do think the whole “5 db” and “completely silent” marketing speak is over the top, I honestly can’t imagine there being any trainer out there that is actually more silent than the Neo. So if excessive sound/vibration is a major concern, I don’t think there is really anything better out there.
While my wife was able to hear my sprints down stairs, I think it is important to note that she only heard the sprints, not the whole workout. This in itself is a great improvement over my previous trainer, which was heard downstairs at all intensities. And seeing as how I’ll be doing base workouts for the majority of the winter, I think the Neo has more or less resolved my noise issues.
