The product you are showing is a Kryptonite brand U-lock, most likely a Kryptolok model, which includes an extra cable and a carrying bracket.Kryptonite Kryptolok U-Lock with Cable ReviewThe Kryptonite Kryptolok is one of the most recognized bike locks due to its combination of security, durability, and ease of use. Here is a detailed review:Design and ConstructionThe Kryptolok U-Lock is designed to be tough and reliable. The main body of the U-lock is made of hardened steel, making it difficult to cut with hand tools such as bolt cutters. Its size is suitable for locking both the bike frame and a wheel, providing excellent protection in urban or high-risk areas.Extra CableThe package includes a flexible steel cable that can be used to secure the front wheel or any additional accessories, adding an extra layer of security. While the cable isn't as robust as the U-lock, it's a useful addition to protect various bike components.Locking MechanismThe lock features a double locking system that secures both ends of the U-bar, increasing its resistance to twisting attacks. It also comes with two keys, which is handy in case you lose one.Carrying BracketThe included bracket allows the lock to be carried on the bike frame without any problems, which is ideal for cyclists who prefer not to carry the lock in a backpack or bag. It's easy to install and keeps the lock secure during the ride.Pros:• High resistance to cutting and theft attempts.• Includes an additional cable for added versatility.• Easy to transport thanks to the bracket.• Good balance between price and security.Cons:• The weight can be a bit high, although this is normal for locks of this type.• The cable is not as secure as the U-lock for protecting more expensive components.Final VerdictThe Kryptonite Kryptolok is a solid choice for those looking for a high-quality, high-security lock for their bike, especially in combination with the additional cable. It is ideal for urban areas where the risk of theft is higher.

We mounted these to our Lectric XP 3.0. Because of the awkwardness of the ebike frame, we should have went with a wider and/or longer lock. It isn't long enough to really lock a wheel real good, and isn't wide enough to secure the step through mid frame. This would be a good secondary lock for the XP 3.0, but not the primary. The supplied mount works great and keeps the lock in place when we travel.

expensive but great lock. requested replacement keys in aug-sept 2024, they arrive dec 2024

Originally I had bought a simple master lock for my Ebike security. But after watching some bicycle.aecurity videos, I quickly realized that I needed a better lock. This lock fits the bill. i am happy and really trust that a bicycle.qould either go for easier prey/lower hanging fruit, or have to put in a good hard couple of hours worth of work to have my bike. A worthwhile investment, i would recommended .

I use this lock for my Trek FX3 Disc. It can fit the frame and rear wheel at an angle but it would be nice if Kryptonite created wider shackles. I loop the cable around my front wheel for extra protection. So far my bicycle has been untouched.

Bought used, arrived like new! Seems like a sturdy lock and cable, also comes with key/cobo registration in case you lose or forget you key/combo, you can replace them. Another bonus, not available with all locks from kryptonite, register you bike separately than the keys and they will replace if stolen while using their lock systems. I will definitely update in a few months!

THIS IS THE BEST LOCK AND CABLE IN THE MARKET. SOMEONE MADE AN ATTEMPT TO CUT THE CABLE BUT WAS UNSUCCESSFUL IN DOING SO, ONLY MAKING A SLIT DENT ON THE CABLE. THIS IN MY OPINION IS THE BEST THERE IS.
