Is "needy" exercise equipment a thing? That could be a cool product. Or, instead of the bike needing attention, how about the bike feeds/walks/plays with a cute dog. If you don't use it you have an app of your dog begging you to exercise.
We'll put a social aspect in there too. If you sign up with a friend, your pet will start asking for food from your friend if you don't exercise enough (to your embarrassment).
