Want a foolproof lock for your bike that reminds both thieves and yourself that the lock is engaged and means business? Since 1924, Abus has been building locks, so the company knows a thing or two about security, and the Granit 8077 Detecto lock has all 80-plus years of knowledge packed in it. Tired of cheap private-label Chinese locks that freeze up or fall apart? Well, the Granit Detecto is made in Germany, so consider it the Maybach of bike locks. Abus constructs the beefy 13mm bolt, lock body, and locking mechanism of propriety hardened steel that actually gets harder when heat in any form is applied to it. Good luck, thieves!
Adding to the substantial steel security is a 100-decibel alarm that has a 3-D detection sensor similar to what makes most smartphones distinguish motion, making every move of the bike or lock an alarming offense. Yes, this mega loudness wards off thieves, but it also will keep you from trying to ride off with the lock still on your bike and looking idiotic in front of your pals (don’t ask me how I know about this).
After using this lock for quite some time I found it to be one of the burliest and easiest to use. The locking action is buttery smooth, there is an LED display that informs of battery levels and activation status, and it even comes with a lighted key for night use. Also, the design of this lock makes installing and removing it a single-handed operation, so the days of fumbling and forcing locks onto your bike’s rotor is a thing of the past. Yes, this lock is a 2-pound hunk of greatness, and the only downside I could ever see is losing the key(s) and having to cut the brake rotor off your bike while donning some serious ear protection. Because that’s the only way this thing is ever coming off the bike without the key. See more abused gear in Products.
