Amazon Customer: Long enough shank so you don’t have to worry about finding something to lock on to. Light enough no issue to carry along

Ellen P: I used many types of bike locks before. I must say, this one is definitely worth your investment! Sturdy and good quality. Plus it comes with a lock holder (just make sure your bike has space to accommodate it because I sadly didn't).

Rodons: I bought this bike lock after reading a recommendation from a friend, and I'm so glad I did. This lock is sturdy, easy to use, and very secure. I've been using it for a few weeks now and I have no complaints. It fits my bike perfectly and it doesn't scratch or damage it. It also comes with two keys, which is very convenient. I feel much safer leaving my bike outside with this lock on. I highly recommend this product to anyone looking for a reliable bike lock. It's worth every penny!

Teri : reputable brand deters thief. Fits secure on provided attachment point. No room for accidental removal while riding.

twistedcedar: I commute to my college campus on an expensive-looking cannonade road bike. Despite there being basically zero bike theft in this town, I'm still nervous. That is, until I bought this lock. I put one drop of chain lube down the key hole, as I have heard of these binding up, and have had no problem in the last few months. My only wish is that the U secured into the lock part with a bit more rigidity, as it can rattle around.

Jay Deegan: The lock is just a high quality U-lock, no problems, act's as advertised. But the attachment that allows you to attach the lock to your bike is kind of wack. Instead of the high-quality metal that the rest of the lock is, it's this cheap plastic. The lock attachment is advertised to fit inside your frame, but for my size Large bike, with a water bottle holder it just didn't work out. Maybe on comfort bikes it would work, but defiantly not on a front-suspension, hybrid bike. So instead I kind of had to put it on the outside of the bike, somewhat by my gears, it was just a weird attachment process overall. I wish that there was a way instead of doing a 1/2 decent rope thing/rubber to attach, it would come with a option of just drilling, or a just a better attachment system overall. It's just annoying how nice the actual lock is, but then the attachment is so cheaply made. Again, no problems with the lock in itself, if you are just buying it to lock, and not to attach to the bike 5/5 recommend.

Client d'Amazon: 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

Súper seguro .

FlavioFlavio: 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.
