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

Very well-made. Locks on both sides to give added security. Very durable easy to transport.

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

This thing just rocks on so many levels. I feel confident using it at almost any location

Good lock, but living is a high thief area, I choose a different, what I feel was better for my purpose

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.

Watched a review of e-bikes on YouTube about making your bike less desirable to thieves. They recommended ABUS as having really good locks. They stated that all locks can be overcome, but stated that this brand takes a lot more effort than most others. Purchased two of these locks, one for each of our bikes. This is a very heavy duty lock. It definitely will be difficult for someone to cut through this twice, in order to steal our bikes. The fit and finish of the lock is impeccable. This was a bit of a budget buster, so hopefully in the near future we can afford to purchase the matching chain locks.

Significantly lighter than the equivalent Kryptonite product, and for me, that was enough to warrant purchasing it. Further, significantly more Kryptonite reviewers noted problems with their locks getting jammed up and the key not turning in the lock, this despite application of lock appropriate lube. This happened with Abus users, but it was a lot less. This lock was made in Germany, the Kryptonite lock is made in China. To me, that says a lot about why there is a difference. Ive had this lock for about two days, so we will see how it goes. Lock was shipped quickly, and weirdly, there was no packing material in the box. Not that the lock really needed any, but still.

Needed a strong and reliable lock to secure my bike around campus. This works. Pros: Thick, hardened steel shackle. Lightweight for its size and strength. Thin layer of rubberized material on the inside of the shackle to protect the paint on your bike. Key retention, so that the key can only be removed when in the locked position; never accidentally leave your bike unlocked! One key has a handy little LED light built in. Also comes with a smaller spare. Included card with personalized code to order new keys. Cons: None, absolutely worth the money.

Item appears to have been used. Seems sturdy enough, but for over $100, I kinda expect one that isn’t already all beat up.

I like the apparent sturdiness of the lock. Feels like it would take some time to grind thru it. Bolt cutter might not be a good tool to use on it. The tradeoff is that it is a bit heavy. Not an issue for me, but some might not like it.
