KryptoniteKryptolok 12.7mm U-Lock with FlexFrame-U Bracket

Good item. Works well. Recommended. Supplied bracket won’t fit electric bikes with odd shaped down tubes

Heavy but solid. Should keep thieves at bay. Makes them move on somewhere else. Usefully long u shape.

The lock stop working just after using it three times. The lock stuck in open mode would no longer work after very short use.

I’ve had this lock for years. So, I bought the same for my wife’s new bike. Solid build and easy to install. It’s a great deterrent to thieves…not a fan of chains…too cumbersome. This lock tucks in and out of the way 👍

after a hoodrat tried desperately to steal my bike, he found he couldnt and began to destroy my brakes and dent the parts to my bike. I was appalled but I took it in stride. I had just walked into amazon fresh in pasadena to get some items, not realizing someone was ruining my bike outside. I came out and tried to unlock it and it was jammed! The criminal sat on a bus bench and didnt even leave!! altho, he covered his face w/ his hands! I had to go back into amazon fresh and ask for assistant. A guy in the back got BOLT CUTTERS. He just happened to have them, because he said "when employees leave they lock the storages". He broke through my severely damaged ulock offbrand that I bought here on amazon. I then realized the creep had hurt my front wheel so badly i had to drag it all the way home! I literally had to walk my bike home. I went back in and asked him to help me to make my front tire move!Thanks to the guy at the Amazon Fresh in Pasadena who was very helpful. You should tho have a bike area to lock your bike CLEARLY IN FRONT OF THE STORE and not off way to the side. This probably would have NEVER HAPPENED if you knew where to places to lock your bike.Which brings me to this lock. It took 100.00 to repair my bike and get this lock, and its nice and long, easy to turn once you figure it out and very sturdy.I will never lock my bike by far from a store. I will never lock my bike by a bus bench. I will never be out after 10 and LEAVE my bike locked where criminal element surely can exist.

Dès le début, une seule clé fonctionne et pas super bien encore. C'est mon 1er achat de cette marque est bien je suis ultra déçu. Je déconseille

El mejor que he tenido .Súper seguro .

Montato in 10 minuti il supporto,qualche regolazione e via. Sembra essere di buona fattura e ben resistente. Certo io lo utilizzo su di una bici da meno di 200 euro quindi va benissimo,si integra perfettamente sul telaio senza dare troppi problemi,un po' pesante,ma significa anche che è robusto,lo consiglio chi come me deve usare la bici in città per andare a fare la spesa o andare a lavoro.
