Its kind of like saying "Quake is cool, but I don't know why I would ever want to play multiplayer..."
If you have the motivation to keep yourself on a bike with just some headphones or a video on a tablet, more power to you, but there are many of us who can't do that. Add in that this has replaced my wife's multiple times a week soul cycle habit, with each class being $40, and Peloton is actually a significant cost savings in my home.
+1 for the IC4, it seems like a much better piece of kit than it had a right to be at the (pre/early pandemic) price point - like $800 IIRC.
And I definitely wouldn't say I'm a member of the "culture", I get on, do a class, get off, that's it. The price is worth it for two people in the house I think.
