Review on Enhanced ABUS Ultra 410 Bike U-Lock: Boosted Security and Durability by Ken Ayo

So far so good! The Abus bike lock appears to be secure, but has not yet been "tested" against real bike thieves. I had a Kryptonite bike lock a while back and I definitely saw someone try to pick that lock (the rubber band on the end of the lock was cut but not the metal part of the lock). Abus Castle is intact today, so as far as I can tell there have been no attempted break-ins. I really like the size of this particular model as it also allows me to mount my rear wheel. No excess is left for the eventual use of a jack etc. No problems with the key as others may have suggested in their reviews. A little heavy, but I'm fine. I like this lock so far. The cable is of course for your peace of mind, it won't stop a bike thief with tools, but it will deter an enterprising person). They are 100% safe (at least in this price range). Anyway, I'm not willing to pay 100+ for a bike lock.
