This is a great hunt! My father is a biker, everyday he will get on his bike and go somewhere as his way to exercise, so this will really help people like him.
Pros:

• one good feature of this lock is that it measures the distance between you and the bike, not just that, you can check where it is on the map, so if ever it got stolen, you will know where it is.
• it locks automatically. So you won't have to worry about forgetting to lock it

Cons:

• none so far
