I would only add to buy the best, most intimidating lock you can afford. I had an Orbea Orca stolen years ago. I had an expensive bike with a crummy lock. Totally my fault. If your lock is going to be a lot of work to cut through, thief may just move on to the next opportunity. People seem to like Abus locks. I use a Sigtuna. It is large and heavy and I do believe it is a disincentive to bad guys.
