📋How we compared
We did not test or try to break these locks. Resistance to cutting or theft cannot be judged from a product page, and no lock guarantees that a bike will stay put. This comparison is based on the product titles and feature lists on the Amazon US listings, retrieved through the Amazon Creators API on November 3, 2026, and on general knowledge of bike locks. Dimensions, ratings and security claims are statements by the sellers or the rating bodies, not ours. Prices change often, so check them at the store.
💰 Lowest price: Per the listing, the Master Lock 8320D is a U-lock with a hardened steel body, a vinyl coating and a disc keyed cylinder. It lists a 7-1/4 inch width, a mounting bracket and two keys.
