ABUSAnti-Theft Key Lock Black Bike Lock, 108mm Diameter, 13mm Thick, 230mm High

I love how hefty this lock is compared to my old one. The best feature for me is how long the U-lock is. There aren't many bike racks in my city and I have a cargo style bike, so locking up my bike with a short u-lock is very difficult. I thought I would need a chain lock but this has worked great. I can lock it up anywhere.From reviews I saw, this is one of the toughest locks to brake. The lockpickinglawyer had trouble picking the lock to. Anyone who tries to break this lock will give up and move to another lock.

The lock is large and heavy, but a pain to bike around with, dangling from your handlebars of tucked in your clothes. People at Abus are smart. I'm surprised they have not thought of a better locking system.

Abus makes 2 different brackets for this lock, the USH540 and the Eazy KF. This listing includes the USH540, as listed in the model name. I installed it on my seat tube and it holds the lock securely while I ride. Good secure lock.

The Abus Granit X-Plus 540 is very good, but not the best...The 540 offers a good measure of protection, this is unless thieves equipped with an angle grinder. With an angle grinder the lock can be defeated with two cuts in less than 3 minutes.I like that this lock comes with hardware that can mount the lock neatly on most bikes. The 540 weighs in at about 3.25 lbs. and it can be bought for around $100For greater protection, I also had purchased the Hiplock DX1000. In comparison the DX1000 is at about 5.5 lbs. and cost $350, but it will resist lock attacks for about 15 minutes or more. If you have an expensive e-bike, this is a good investment in protection.In lower risk areas the 540 seams fine. If I know that I will be leaving my bike a long time or in questionable areas, I'll bring both.

Ive been watching the various listings on Amazon for the 230MM and 300MM X-Plus locks. Most listings are now going between $90-$150 but the 230MM model on this page has been dipping down to $52-$55 for short periods of time. Jump on it like I did if you see it at that price.The photo on this listing is for the silver/black 5.5" "Granit-X Plus 54 mini" lock, NOT the grey/black "Granit-X Plus 230MM lock.The lock comes with a card containing your lock's keycode if you need to replace the keys. You can also use the code to get a keyed-alike lock (only other Granit-X plus models are compatible).The 230MM lock (sold/shipped by Amazon) comes with the "ABUS USH 540 Bracket/18576 Mount" bracket/mountIve noticed that bracket's installation instructions have caused some people confusion. The photo directs you to put 2 screws thru the mount and it looks like doing so will interfere with sliding the lock/bracket into the mount, which is true, but that is because you are supposed to first slide the bracket into the mount then drive the two screws thru both the bracket and mount to secure them to your bike frame. The bracket isnt designed to be removed from the mount. Both parts are designed to stay mounted to the bike and you just unlock the lock to remove it.im not a huge fan of the mount/bracket as its pretty limited and there are some weak points built into the design. Its secured to the bike like a clamshell with the mouth held closed by 2 screws. The diameter of the mouth of the clamshell shape is too small in diameter to put it most places on my bike and I had to put it on the chainstay triangle bar. The part of the clamshell that joins together is way too thin, and the more you tighten the 2 screws, the more likely it is to stress that thin part of plastic. Seems like the like the first failure point for this mount.I bought the Kryponite Flexmount U Bracket vr2 to have a more flexible mount for my bicycle. Some complain that bracket is also fragile but Ive had one for 4 years with no issues. If you cut off the sleeving on the shackle of the u-lock, the larger metal spline will fit over it. Youd have to do the same thing to use Abus's other widely available "ABUS EaZy KF Bracket". Abus has another newer "universal" mount "Bracket SH B" but I havent tried it.Im probably going to buy a chean waterproof seat cover or something like a showercap to put over the lock to keep water ingress to a minimum. I dont think these locks were designed for really cold and wet conditions.PS: Dont judge the condition of my drivetrain... I let it get Vvery bad. I have all new parts waiting I just wanted to run these parts into the ground before doing a full overhaul. lol

The bike lock mounting hardware not fit Rad Mini Step thru E Bike frame. Other wise it looks and feels like a super heavy duty bike lock.

I bought this because this keeps coming up as one of the best. I'll be honest though -- I'm returning it because I would never use something this big. So, if practicality isn't there it's just useless. How am I supposed to ride with something this big? It may in fact be less heavy than the rest of the market, and just as strong, but if it's too big, too heavy, and just too much of a pain to use, I ain't using it! So 5/5 for quality and 1/5 for practicality.Now, the good things -- it's strong, I feel safe with it, it could** be carried if I installed the bracket (I am whining a bit...), and I wouldn't try stealing the bike with this lock on it, and it definitely fits around both** the frame and wheel.One thing that concerns me is that it leaves A LOT of room for a leverage attack, although I highly doubt it could be broken easily that way either, but who knows...For that reason, I chose the 5.5" mini rather than this.In fact, here's what initially happened:1) first i ordered the mini version of this2) then I got it and was like "wtf, this won't fit anything!"3) then i ordered the bigger version to try4) then i got the bigger version and said "this is way too big"5) I stuck with the mini version, and I'll just see what happensThe mini works -- just barely, and perhaps maybe even just the frame most times, but I'd much rather have that than this. Now, I will say this -- this is good if you plan on leaving or locking your bike outside for a while. I don't plan to do that, so this isn't practical for me. I want a strong lock for lock and go situations like stopping at stores, going grocery shopping, etc.

Lo use para dejar mi bicicleta en el centro de la ciudad y por tiempos largos. Es eficas

Based on the ratings I read (on Amazon and numerous review sites), this product will stand up to the crooks better than most. The downside is it is a bit of a heavy beast (or else it wouldn't be effective). It's as easy to use as any U-Lock. I like that the whole lock mechanism slides off of the U making it easy to place around the bike frame and whatever it's attached to.

Abus is the go-to brand for anti-theft devices, and this model is a prime example of their quality. Its high security level meets the standards required by nearly all insurance companies, which adds extra peace of mind. I’ve been using this lock for almost a year alongside two other Abus devices, and I couldn’t be more satisfied!

Es un cierre muy seguro. Aunque lo tuve que devolver porque era muy n poco grande para una reja. Una pena

The media could not be loaded. J’ai acheté cet antivol ABUS Granit 540 pour sécuriser mon VTT Nakamura Summit Ltd. Il m’a coûté 80 euros. L’antivol est livré avec un support de fixation USH et différents adaptateurs, qui permettent de le fixer à différentes épaisseurs de cadres. J’ai opté pour un U de 23cm pour réduire l’encombrement et le poids sur le vélo ; je ne regrette pas d’avoir fait ce choix. Par ailleurs, j’ai privilégié le support USH au EaZy KF car je ne voulais pas prendre le risque de me faire voler le cadenas et son support dans un moment d’inattention.Ce cadenas est de très bonne qualité ; il est livré avec une clé avec bouton pour éclairer la serrure. La seconde clé en est dépourvue. Une carte de propriété permet de faire faire des clés supplémentaires si besoin. Le cadenas est classé au niveau de sécurité maximal par ABUS, c’est-à-dire à 15/15. Techniquement, cela permet de protéger des vélos onéreux et cela convient bien aux zones à risques.Après un petit temps d’adaptation, je verrouille le vélo en quelques secondes et met le même temps pour assembler le U sur sa serrure lorsque je reprends la route. Je suis content d’avoir choisi ce modèle (plutôt que le Granit 460 par exemple), néanmoins je pense qu’un individu équipé d’une meuleuse sans fil et d’un disque à tronçonner le métal doit réussir à couper le U. A mon sens, il s’agit d’un antivol dissuasif et de haute qualité, mais pas indestructible pour qui peut agir tranquillement à l’abri des regards.En conclusion, je ne regrette pas mon achat, que ce soit pour le support de fixation USH comme pour la longueur du U (23cm). Je conseille cet antivol ABUS Granit 540 en raison de sa robustesse et pour sa finition de qualité. Cet accessoire dissuasif est un complément indispensable aux vélos onéreux.Climaxe
