I've had one for a bit over a year now and I really love it. You're exactly right about the hook for this product. Before using the bike I've just stuck with the same training I did in high school football because I've always needed structure and a way to track progress. The bike classes are kind of addicting since the instructors keep the tempo up (depending on the class) and you have leader board showing with a live ranking. Even if you aren't at the top it's still fun because you'll get used to seeing the same names around your rank (if you're doing the live classes) and it'll push you to compete with them. It's a lot like having a running group except you'll always have someone that is around your skill level to compete with.
