Kryptonite to thieves.

Bike thieves should beware of the Kryptonite Evolution Series 4 1090 Chain Lock. With 10-millimeter, 6-sided chain links made from 3T Manganese steel, it's anything but easy to break. This burly lock can secure your pride and joy with confidence, and it won't scratch your frame in the process thanks to its durable, weather resistant nylon sleeve. The Evolution Series 4 1090 features an End Link Design that secures the chain to a hardened deadbolt to eliminate critical vulnerability at the end of its links, and uses a pick-and-drill-resistant high security disc-style cylinder.

Kryptonite is so confident in the Evolution Series 4 1090 chain lock that it gives it a whopping 8 out of 10 on their security scale, and stands behind it with their Anti-Theft Protection to help you recover if anything happens to your trusty steed while it's locked up.

When registering my lock, where do I locate the serial number of my Evolution Series 4 1090 for the application?

Also, on your question re: bicycle info, I'm not sure how to answer the about SIZE. It's a full size bike for men.

The registration number you need is on the key. I'm not seeing a spot on the registration form where it's asking about the size of the bike, however.
