My friend has a Peloton and because the screen is built in, if you cancel the subscription I don't think the screen works anymore. You could put the bike in front of your TV and use a Youtube video I guess but then it really is just a very expensive bike.
We've just ordered an Apex Ride - quite a bit cheaper (but still pricey) no in-built screen, you just use your iPad or whatever so you don't have to have the subscription necessarily. It is worth it for us as we try to spin a lot but it's increasingly difficult to get on the classes now the gyms are opening, plus they offer a better range of length than the ones at my gym. So the gym has 45mins/one hour, sometimes I don't have time and the Apex has shorter classes like 20 mins which I can almost always fit in. Given we're facing another lockdown potentially I am glad we ordered it. With home spin bikes, I've tried a few cheaper ones and you get what you pay for tbh.
