I own a Peloton bike, but yeah I don't watch TV, and I had to look this up, lol. Are you talking about this one? https://www.youtube.com/watch?v=MDVnBl2piuE
God, that singing is awful and I don't think it's a great commercial honestly.
These bikes and the accessories that go with them are eye-wateringly expensive, and so is the content subscription ($40/month), but wifey wanted one for Christmas, soooo...
Honestly though: Peloton gives you a great cardio workout, and the instructors are fantastic. Only been riding for about 3 weeks now (once in the evening, and up to 2-3 times a day on weekends). I've lost tons of weight already and feel great. We have never been great about incorporating visits to the gym into our busy lives, so home exercise equipment is a godsend to us.
Peloton is supremely faddish and kind of cultish, and the price is outrageous, but for my wife and I, it works.
If you really want this bike and don't have north of $2000 just lying around, there is a ~$60/month interest-free payment option which is what we did
