Description

The Kryptonite Kryptolok Standard U-Lock features a 12.7 mm hardened performance steel shackle with a double deadbolt anti-rotation design that resists bolt cutters and twisting leverage attacks. The lock’s disc-style cylinder with center keyway is protected by a vinyl coating and is pick and drill resistant. The keyway also features a sliding dust cover to protect the cylinder from dirt and debris when not in use. It includes two stainless steel keys with an ergonomic design to reduce torque and keep them from bending or breaking. Rated at a 6 / 10 on our security scale, the Kryptolok Standard is good for quick stops in a metropolitan area, a couple hours in the suburbs, or all day & overnight in rural areas. It also includes our patented FlexFrame-U Bracket providing convenient multi-location U-Lock transport. This lock is also bundled with a KryptoFlex 410 (4' 10mm) double looped braided steel cable for securing front wheel or accessoires. The combination of these great features and our support programs including Key Safe, Anti-Theft Protection, and Lifetime Warranty make Kryptonite Bicycle Locks the best choice for protecting what you value.

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. ... show more

    • Great lock! Use WD40 and teflon chain lube if it gets stuck/hard to turn key
Size: 4" x 9" 12.7mm & 10mm x 122cm Style: Standard_w_Cable
Review Image by Brett Brett
This lock is so good. I'm coming from the Evolution model which I loved and secured my bike, but someone stole the entire rack it was locked to and the price went up so I went with this model lock instead. The mounting adapter that goes onto your bike is great! I keep the lock clipped to it as I ride around, the key goes on my key ring and it fits well and keeps my bike secure. I did have some trouble using the key or undoing the lock, so I sprayed some WD40 on the part that comes apart and in the keyhole. Then I used teflon dry bike chain lube on the same parts and in the keyhole, put the key in there and turned it a bunch. Now it works perfectly and is easy to lock or unlock! If you need a solid U-Lock with a bike frame mount - THIS IS THE ONE! ... show more

    • Appears durable, maybe not best size for Lectric XP 3.0 though
Size: 4" x 9" 12.7mm & 10mm x 122cm Style: Standard_w_Cable
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. ... show more

    • Very sturdy lock that is easy to use and it comes with an extra cable which is very handy.
Size: 4" x 9" 12.7mm & 10mm x 122cm Style: Standard_w_Cable
I would have given this item 5 stars but it came without the bracket to attach to the bike frame. I have used Kryptonite brand locks in the past and am very happy with their quality.

    • Bike Lock that Secures Your Mind
Size: 4" x 9" 12.7mm & 10mm x 122cm Style: Standard_w_Cable
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. ... show more

Lock is great and tough, I just wish my town invested in racks with larger loops so I could actually use the cable to attach my bike to the secure stands.
