A great lock, but a little short. That makes it hard to lock your bike to a railing or post if you can't get right up against it. Other than that a very good lock, much better than a chain and it really does seem to be indestructible.

The lock is sturdy enough. It comes with a bracket that attaches to your bike. The problem is, the slightest bump breaks the bracket, making it impossible to secure it to your bike for transportation purposes. It is unfathomable to me that I paid over $100 for this lock, only to have the bracket broken and now can no longer secure it to my bike.

I went with this ABUS lock, after reading about key operation / locking cylinder problems with another brand. This one operates very smoothly (after 1 month of operation). I love it!! I also chose this one, due to the high ART and Sold Secure GOLD ratings. Yes, it is heavy ... but a 13 mm chain for the same application is heavier ... and this is just as secure. I'm also using the USH mounting bracket, attached to the seat post tube (Trek Verve 3 Disc). It fits perfectly. The U-shape portion runs parallel to the top tube. I added a velcro strap to provide added support, wrapping it around the bike top tube and the u-shaped portion at the far end. So far, with about 200 miles, the mounting bracket + velcro strap have worked great! (The miles have been over mostly sidewalk riding, with some pretty bumpy cracks/joints.) Very, very happy with this product. Highly recommend it!

I'm new (again after a 10 year hiatus that is) to biking. I bought a new bike which set me back $1600 (a bargain these days apparently).I researched locks, fully expecting to get a Kryptonite. At this price point though I decided to go with what other reviewers said about this one. It seems like a good choice.I like the long U shape of the lock. It makes it easy to secure the bike to things. As others have noted the key system is great, works easily every time.I had to look on Youtube to figure out how to install the mounting bracket but it was easy. One thing to note is I was going to install a bottle holder on my frame also but this lock is so big I don't think I can do that now. That's ok, not a big deal. Would still rather have a quality lock like this.Not much else to say about this, it's just a bike lock but seems to be well made (comes from Germany after all), has a killer lighted key that comes with it and all around an excellent lock.

Quality of craftsmanship shows. Other locks just cant compare, no matter how brand loyal you might be this one will win you over for life! When you insert the shackle into the lock it really has an impressive, solid, secure feel to it.... almost like closing a door on a German made high quality sedan. The 12 inch shackle inside height along with the 4.25 inside width makes it great for my fat tire e-bike, I can get it around the rear tire and my seat tube and use another to secure it to a rack, or the rear tire and lower frame to a rack. The weight obviously isn't an issue for me but I find it very easy and manageable to use. I keep it secured to my rack and tube for transport as I feel the included mount in my application and riding habits may not stand up... I don't want it dropping off an 30+ MPH. Don't think about it, just do it, 2 of them equaled the recommended 10% of the value of the bike for me.

When I bought this, I thought it was one of the best rated U-Locks on the market. Turns out that's a slightly different Abus that doesn't seem to show up on Amazon. Oh well. Still WAAAAY better than a cable lock.So far, no theft, so I can't personally attest to the security of the lock. But I can tell you about the ergonomics: this thing is BIG. Which makes it useful for locking your bike up to non-ideal structures (the extra reach of the U is helpful). But it makes mounting trickier. If trying to mount it in the center triangle, it totally eliminates even being able to fit a bottle cage. There are a few ways to mount it to the side of the seat post, parallel to the bike, but those interfered with my rear-mounted kids seat. I ended up mounting it on the rear seat-stay, and it seems to be working nicely there.That being said, the mount that comes with the lock is MUCH better than the mount that came with a different U-Lock i purchased. It gives you a lot of flexibility in mounting options.Yes, this thing is heavy. But I don't notice it, and you probably wont either unless you're a pro racer.

El candado parece muy robusto, la llave es de buena calidad y gira bien. En general los materiales son buenos y la goma que lo recubre es buena tambien, espero que resista con el tiempo, pero a los golpes es resistente y agradable al tacto.El soporte que trae también es muy bueno y con un diseño bastante acertado que hace que no se mueva nada cuando vas en la moto con el guardado y es fácil de poner y quitar el candado en él, que para mi era algo crucial.Muy satisfecho con la compra.Como pega diré que el cierre del candado, la base por decirlo así , es muy ancha y en mi moto no entra bajo el asiento

I had a heavy chain to lock up my trek. I thought that was more than enough. Come to find out it could be defeated in less then 30 seconds. Not this sucker. It is HEAVY DUTY. Very substantial with a great frame mount included. I actually mounted it on the rear tire triangle on the outside of the bike. It doesn’t interfere at all and helps make it easy to unlock and lock again. This is the best lock out there in my humble opinion. If someone wants to steal my bike, it will take them at least more than a few minutes to get it! Read some of the independent insurance reviews from the UK to see how your current lock stacks up and you’ll be back to buy this in an instant.

Pour mon vélo j’attache la roue arrière avec cet antivol niveau 15 abus et l’antivol à boucles abus pour la selle à l’arceau, il est très solide et facile à manier j’ai monté le support sur le cadre vertical pour le transporter, très pratique, facile à installer. Le grand modèle est plus pratique pour moi à attacher lorsque l’arceau est épais. Je double avec un antivol pliant niveau 15 abus pour la roue avant attachée avec le cadre et l’arceau. Solide également.
