The thing with buying exercise gear for someone is that one should be sure it's something they actually want and not something being thrust upon them, and I think the issue people have with the commercial itself is that this bit of fitness equipment appears to not have been requested and there's apprehension on the part of the woman beginning. And the whole approval seeking thing was just off-putting. Of course the whole seemingly already fit looking person doing a fitness activity for a year makes it a challenge to portray what the benefits are, since a lot of the benefits are in the form of better cardiovascular health and not necessarily outward changes.
As for the bike itself, if it's what people need to get motivated to follow a plan, great. I think it's grossly overpriced for what it is, when one could get a nice entry level road bike and a nice direct drive trainer and a trainerroad subscription (new generation Hammers are under 800, plus a 800 bike and you're still coming out less than a Peloton, plus you can ride outdoors). But frankly that's pretty overwhelming for someone with no background and the plug and play aspect of Peloton is definitely appealing to lots of folks.
