This lock is super beefy and easy to use. It’s about as lightweight of a lock as I’d use to secure our expensive E-Bikes. Make sure to register for the warranty program to further protect your bike.

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 👍

Strong and dependable lock. I bought this for my daughter to prevent her bike from “disappearing” on her college campus. Much better than the standard cable lock.

the included storage attachment is very stiff and hard to get the lock in and out of.

I purchased this as a replacement for a 5 year old version which sadly was going belly up. My first purchase of this type of lock was through a different store other than Amazon and I paid approximately $20 plus tax. Inflation has obviously taken it's toll as the new one was almost 3 times the cost of the original. It appears to be the same quality though. Should it last as long or longer then it's worth the cost. Actually, it's worth the price in protection against bicycle theft. I don't live in a city like Los Angeles or New York. I live in a city of approximately 100K. Bike theft here is real. I've known people with cable locks have their bicycles stolen. My recommendation for a bicycle lock is a U-lock. Preferably a Kryptonite like this one or one of their higher quality ones meant for larger cities. It may be heavy to carry around without the provided carrier, but it's better safe and sound then seeing a high end bike be stolen with lesser locks. I personally have ridden bike exclusively for over 24 years now. My recommendations for locks are U-lock, cable lock, then chain link if nothing else.U-lock being the toughest and chain link being the weakest.

This works quite well as no one has stolen my bicycle so far. The only negative is the holder will shake loose so i put the lock in my pack to transport it.

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.

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!

My experience with this lock has been nothing short of a nightmare. Here are the reasons why I cannot recommend this product:Gets Stuck Every Time: The most infuriating issue with the Kryptonite Kryptolok is its infuriating habit of getting stuck when I try to unlock it. It's supposed to be a quick and convenient way to secure my bike, but more often than not, I find myself wrestling with it for far too long. This not only wastes my time but also leaves me worried that I'll be stuck somewhere, unable to unlock my bike when I need it the most.Scratches Bike Frame: I don't use the included bike mount. However, the aluminum buckle is not removable and consistently scratches my bike while riding.Lock Scuffs Easily: To make matters worse, the Kryptolok itself is prone to unsightly scuffs and blemishes. It looks like it's been through a war zone after just a few weeks of use.In summary, the Kryptonite Kryptolok bike lock has been a massive disappointment. Its tendency to get stuck, scratch my bike frame, and scuff easily has left me frustrated and regretful of my purchase. I would strongly advise anyone in need of a reliable bike lock to look elsewhere and invest in a product that will actually keep your bike safe without causing more problems than it solves.

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.

Ich bin ganz zufrieden mit diesem Schloss. Ich habe auch schon den Vorgänger über 10Jahre im Einsatz. Die Wertigkeit zum alten Modell ist gestiegen. Es gibt auch einen Schieber mit dem man das Schlüsselloch verdecken kann. Die Halterung ist auch deutlich besser als beim alten Modell. Schade finde ich, dass man jetzt das Schloss gerade aufschieben muss. Beim Vorgänger hatte der Bügel auf einer Seite einen Haken. Ich fand das im Handling deutlich angenehmer. Das war auch ein Grund warum ich kein anderes Schloss gekauft hatte.
