Review: It’s great - 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 Review The 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 Construction The 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 Cable The 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 Mechanism The 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 Bracket The 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 Verdict The 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.

### ⭐⭐⭐⭐⭐ Smooth lock
*by D***E on August 11, 2026*

Great lock..Very smooth lock

### ⭐⭐⭐⭐⭐ Bike Lock that Secures Your Mind
*by M***X on August 10, 2025*

One of the most user friendly locks I've seen that leaves you without worrying if your bike would be stolen. Even though the width of the bar is thin it seems very dense which might help in case an unexperienced thief tries to break it. Unlocking this bike with the key that is given is easy and doesn't require that much of a struggle. All in all, its an affordable lock that gives you more than what you pay for.
