Best Overall: Master Lock 16 mm Bike Lock

Buy on Amazon

The Integrated disc key locking mechanism offers maximum pick resistance. It features a hardened steel body and double locking shackle for superior cutting and prying resistance. The key can only be removed when the locking bar is in the "locked" position. It helps to add a bit of security theater for you and a potential thief.

The lock comes with 2 keys, made for that specific lock. The cable allows you to lock the front tire to the main lock which is great for bikes with a quick release tire. The lock mechanism is fairly sloppy, and best results are achieved by fully inserting the key prior to unlocking, and ensuring the key is fully inserted while locking. The plastic carrier bracket is a nice addition to assist in easy transport.
