ABUS U-Lock Granit XPlus 540, Bike Lock with XPlus Cylinder, High Protection Against Theft, ABUS Security Level 15, Black/Grey

This provides the same or better serious battle toughness as the other beast locks, but in a lighter package. Superb German manufacturing quality. Worth every cent.

Heavy and doesnt come with a holder to secure it to the frame while riding, so its kinda pointless. Its a sturdy, quality lock, but not easy to transport around with you. Really needs to come with a mounting bracket.

This lock is a bit heavy, but you do not want a light, cheap lock for your bike. This lock is strong and easy to use. It comes with two keys, one with a led light on it. I love this lock and feel very secure with it on my bike.

I researched the security level of many different locks. An expert who teaches lock picking and bypass mentioned Abus as one of the best brands to defeat such efforts. The only way to get into this lock is through brute Force. Im sure that is possible, but as long as I have a better lock than the guy next to me, most criminals will move on to an easier lock.

A bit heavy and expensive, and the bracket was pricey, but when someone tried to cut through it with a hacksaw, they broke through the rubber exterior, scratched the steel core, and then gave up. About 5 tries around the lock with a saw, and no luck for the robbers. They blemished an otherwise very pretty lock, but thats all. Very pleased with the performance. Honestly, Im surprised they tried at all. To pick this thing up, it reeks of quality and high-end design. Doubles as a weapon. Im sure the right tool exists to cut it, but the sound it would make and the time it would take would make using such a tool challenging if not extremely difficult in any outdoor setting. This has now paid for itself.

Nice and wide enough to lock the frame and the rear tire. Very happy with the purchase.

Suddenly the key stopped working Luckily the bike wasn’t locked But lock components don’t move when key is turned

great product

Good lock, saved me a long trip to the bike shop to buy.
