+1. You can get a digital membership and stream through the app, on your computer, or on various streaming hardware (Roku, FireTV, Apple TV, Chromecast, etc) -- I believe it's $13.99/month. Actually in some respects a better value, especially if you already have your own spin bike or treadmill (or even elliptical -- I sometimes do the running classes on my elliptical to save my knees but still have the class) and can just stream the classes to a TV or tablet. You just don't get a spot on the leaderboard if you are using the app -- which is a YMMV depending on how competitive you are and how much you care about the leaderboard.
If you don't have a Peloton (and have no interest in buying one), it would still be worth snagging the Digital Membership since you basically get a few months free. Worst case you set a reminder on your calendar to cancel it and get rid of it when you've used up your credit.
