There are several questions already about what's the best bike lock. I'm just looking for information on lock rating systems. I've found a couple rating systems in countries like UK (Sold Secure) and the Netherlands (ART).
Is there a similar rating system in the US? Do they have a decent website that you can search on?
I've found that Sold Secure has a searchable site, but it does not have all of the US brands and models in its database.
