Am I being Self Indulgent?

Is it self indulgent to get a new bike when mine still works? Peloton is my mental health and physical fitness staple. Got the bike about 4 years ago. Much loved, much used. I am at around 2200 rides. I sweat a lot, and I’m not the best at keeping the bike immaculate, though I wipe it down and use a ride hide. My calibration is getting suspiciously easy, but otherwise it works well. Still, I want a bike plus with auto-resistance. Worth it? It’s not going to break the bank, but I don’t want to be frivolous.
