Yes - DH uses it every day so it's worth it for us to keep it. In your case if you're debating it and indicated that you prefer to exercise outdoors and would only use your Peloton occasionally then consider selling it. Perhaps disable your $40 membership before you sell to see if you miss the content in the Peloton library, or not.
