I bought a budget stationary bike and have an ant+ cadence and heart rate sensor and use Golden Cheetah to see the data live on my computer. I don't care much for power generated as long as I feel like I am exercising but it can be estimated. More accuracy would require an extra sensor. It's the same data Peleton shows and if I wanted I could use Peleton for just the monthly subscription price. I paid USD 600(bike) + 20(cadence sensor) + 90(hr chest strap sensor, polar h10) + 20(ant+ usb dongle). I can log my heart rate and cadence on my phone as well, I can move the sensors to my mountain bike. I have an android and use Jepster and upload to Strava.

I love that I am not tied in to Peleton. I chose not to buy clip-on shoes although that's an option and would just require buying the pedals and shoes.

My university had les mills classes and I enjoyed them and so I got their subscription for on demand classes. They have this class called The Trip where they have generated a virtual biking track that is in sync to music. I can't imagine a more immersive at home workout. Les Mills also has full body workouts as well as yoga. There are certain historical workouts that they took down because they don't have the rights to the songs anymore but they release new workouts regularly.

I am looking into Zwift but I can't justify paying the subscription price. If anyone knows any good free virtual biking roads software that interfaces with ant+ sensors please let me know. I don't care as much about the social biking part of zwift.

One day I want to see what VR and exercise can bring but I don't imagine sweating in a VR headset is pleasant. I have only heard good things about beat saber though.
