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

I definitely take comfort in knowing I have the hardest lock to break on the rack. Highly recommenced if you can get it for the right price.

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.

Lock looks sturdy, I would have given a 5 star, but the key that has the light did not have the battery holder or battery. I would have to send the lock back, it wasn’t worth the time to send it back. I am happy with the lock.

This lock feels indestructible, but the key is now permanently stuck in the lock with my bike locked to a rack. ABUS will not replace the lock unless I return it to dealer where I bought it for inspection. That dealer was Amazon, and the return window is long gone. I can ship the lock to ABUS to have them inspect it and determine if a replacement is warranted, but its stuck on my bike/bike rack and even if I could get it off I would be without a lock for a few weeks. I recommend going with Kryptonite bike locks instead, as I have one of those that I purchased in 2005 that still works great 15 years later.

The best U-lock on the market, in my opinion. Its expensive, but when protecting an expensive bike, what price security?? The best thing about it is the German construction, and the DOUBLE end locks, requiring only one key and one key hole. Anyone who calls this lock heavy, obviously has never tested the other high security U-locks out there, thats for sure.

This product feels like a quality u lock. Though no lock is 100% guaranteed I feel confident that it will deter someone from attempting to break it if you leave your bike out for a while. It wouldve been nice if it came with some theft insurance the way kryptonite does.

I just simply love it. Great product, lovely seller

Long enough for my scooter and a nearby post or rack. Beautiful mechanical sound when operated, makes me think of a bank vault door closing. Rubberized covering seems quite tough. Not terribly heavy but would make a fine defensive weapon should you happen to need one.

Excellent lock very sturdy and easy to use. I love the light so you can see the key hole. I would recommend this product.

Great lock; my daughter has a girls bike and it didnt really have anywhere that we could mount the lock so she has to carry it in her backpack when shes riding. But it is very sturdy and we feel that it provides great protection for her bike (on a college campus). She uses this lock to secure the front wheel and frame to the post, but also uses a Kryptonite chain to lace through the rear tire (not as a secure, but faster than using 2 U-locks).
