There’s a unique kind of dread that grips you when you walk back to where you left your bike, only to find an empty space and perhaps the sad, snipped remains of a cable lock. I’ve felt it, and it’s a feeling I wouldn’t wish on any fellow rider. For many of us, our bikes, e-bikes, or motorcycles aren’t just modes of transport; they are significant investments, extensions of our freedom, and sources of joy. In today’s world, especially in bustling urban environments, a casual deterrent is simply not enough. Professional thieves come equipped with powerful tools, and a standard lock can be defeated in seconds. This is why we embarked on a search for a security solution that doesn’t just discourage, but actively defies theft. We needed something that sends a clear, unambiguous message to any would-be thief: “Move on. This isn’t worth your time.” This search led us directly to the legendary, almost mythical, beast of bike security: the Kryptonite New York Legend 1515 Bike Chain Lock 5 Feet.

What to Demand from a High-Security Bike Chain Lock
A Bike Chain Lock is more than just an item; it’s a key solution for securing your peace of mind. In a category saturated with options, a maximum-security lock like this one stands apart. It’s not merely a physical barrier; it’s an investment in the continued ownership of your property. The primary benefit is its ability to withstand a prolonged and determined attack from tools like bolt cutters, saws, and even some angle grinders, buying precious time and creating a significant deterrent that forces thieves to seek out easier targets. It allows you to park your valuable ride in high-risk areas—downtown cores, university campuses, overnight street parking—with a level of confidence that lesser locks simply cannot provide.
The ideal customer for this type of product is someone facing a high-risk security situation. This includes the owner of a premium e-bike or motorcycle, an urban commuter who leaves their bicycle unattended for an entire workday, or anyone needing to secure their ride overnight in a shared or public space. This is a serious piece of hardware for a serious need. Conversely, it might not be suitable for those who prioritize portability above all else. A competitive road cyclist counting every gram, or a casual rider who only needs a lock for a quick coffee stop in a safe neighborhood, would likely find the sheer weight and bulk of this system to be overkill and impractical for their needs. For them, a lighter U-lock or a more portable folding lock might be a better fit.
Before investing, consider these crucial points in detail:
- Weight & Portability: This is the single most important practical consideration. A maximum-security chain is, by its nature, incredibly heavy. You must have a realistic plan for how you will transport it or if it will be used as a stationary lock at a primary location, like your home or office. A lock you can’t carry is a lock you won’t use.
- Security Rating & Performance: Look for independent security ratings like those from Sold Secure or ART, and pay close attention to the manufacturer’s own rating system. For a lock like this, we’re looking at the absolute top of the scale (10/10). Key performance metrics include the chain link diameter (15mm is formidable) and the type of steel used (hardened steel is non-negotiable). The lock mechanism itself, such as a double deadbolt design, is also critical for resisting twisting and leverage attacks.
- Materials & Durability: The core material should be a specially hardened steel alloy, like Kryptonite’s 3T manganese steel, which is designed to be brittle enough to shatter bolt cutter jaws but strong enough to resist other attacks. A durable, weather-resistant nylon sleeve is also essential. It not only protects the chain from the elements but, more importantly, protects your bike’s paint finish from scratches and chips.
- Length & Usability: The length of the chain dictates your locking options. A shorter chain might be lighter, but a longer one, like the 5-foot length of the Kryptonite New York Legend 1515 Bike Chain Lock 5 Feet, provides the versatility to secure your frame and wheel(s) to a wider variety of immovable objects, such as thick poles, bike racks, and railings. Also, consider the lock’s key mechanism; it should operate smoothly and feature a dust cover to prevent grime from seizing the cylinder over time.
Understanding these factors is key to choosing a lock that not only provides maximum security but also fits your specific use case and lifestyle.
While the Kryptonite New York Legend 1515 Bike Chain Lock 5 Feet is an excellent choice, it’s always wise to see how it stacks up against the competition. For a broader look at all the top models, we highly recommend checking out our complete, in-depth guide:

Unboxing the Beast: First Impressions of the Kryptonite New York Legend 1515
The first thing you notice upon receiving the Kryptonite New York Legend 1515 Bike Chain Lock 5 Feet isn’t its color or its packaging—it’s the sheer, unapologetic mass. Lifting the box for the first time is a revelatory experience. At 14.7 pounds, it feels less like a bike accessory and more like a piece of industrial anchoring equipment. Unboxing it, the chain spills out with a heavy, satisfying clank. The nylon cover is thick and robust, neatly stitched and held in place with hook-and-loop fasteners, immediately giving the impression of quality craftsmanship designed to protect your bike’s finish. The chain links themselves are colossal. At 15mm in diameter, they dwarf the links on most other consumer-grade locks, looking more suited to a naval shipyard than a bicycle rack.
The included New York Disc Lock is a formidable unit in its own right. It feels dense and solid in the hand, with a 15mm hardened steel shackle that mirrors the chain’s brawn. The sliding dust cover over the keyway is a thoughtful touch for long-term durability. We were pleased to find three stainless steel keys included, one of which has a handy LED light. Registering for Kryptonite’s KeySafe program was our first step, ensuring we could get a replacement if needed. From the first moment, the entire system exudes an aura of invincibility that provides immediate psychological comfort.
Key Benefits

Potential Drawbacks

In the Field: A Deep Dive into the Legend 1515’s Performance
A lock’s true worth is proven not on a spec sheet, but out on the unforgiving city streets. We integrated the Kryptonite New York Legend 1515 Bike Chain Lock 5 Feet into our daily routine, securing high-value e-bikes and motorcycles in various scenarios to understand its real-world performance. It’s one thing to read about 14.7 pounds of steel; it’s another to live with it. This is where the Legend transitions from a product into a comprehensive security strategy.
The Heart of the Fortress: 15mm of 3T Hardened Steel
The core of this lock’s promise lies in its chain. The links are a monstrous 15mm in diameter, constructed from Kryptonite’s proprietary 3T hardened manganese steel. In our experience, this is the single greatest deterrent to a potential thief. Most bike thieves are opportunists relying on speed and stealth. They come equipped with bolt cutters that can snip through cable locks and smaller chains in seconds. The Legend’s 15mm links render even the largest 42″ bolt cutters completely useless. An attacker would have to escalate their toolkit to a noisy, attention-grabbing angle grinder.
Even then, the battle is far from over. The specialized hardening process of the steel is designed to be exceptionally difficult to cut. It wears down grinder discs rapidly and, most importantly, takes time. As one user aptly noted, “it would take a lot of time to cut through this.” In the world of bike theft, time is the ultimate enemy. The minutes required to grind through even one link of this chain would generate an enormous amount of noise and sparks, creating a spectacle that no thief wants. This isn’t just a lock; it’s a statement of defiance. We found that the mere sight of the Kryptonite New York Legend 1515 Bike Chain Lock 5 Feet was enough to make our secured bike the least appealing target on the rack. This psychological warfare is a benefit that cannot be overstated.
More Than a Padlock: The New York Disc Lock System
A chain is only as strong as its lock, and Kryptonite has paired the Legend chain with an equally impressive partner: the New York Disc Lock. This isn’t just a generic padlock; it’s a purpose-built security device. The 15mm max-performance steel shackle perfectly matches the chain’s brawn. Critically, it engages on both sides with a double deadbolt locking mechanism. This is a vital feature that we always look for, as it means the shackle must be cut twice to be defeated, effectively doubling the time and effort required for a grinder attack. It also provides immense resistance against prying and twisting leverage attacks.
The lock body itself features a patented hardened oval crossbar, which is inherently stronger than the typical round tube designs found on lesser locks. Inside, the high-security disc-style cylinder is resistant to both picking and drilling. During our testing, the key insertion and turning were smooth and decisive. However, we must address the feedback from some users who received locks with sticky mechanisms or heavy wear. This seems to be a fulfillment issue from certain sellers rather than a widespread manufacturing defect. Our new unit performed flawlessly. We strongly advise buyers to check the lock and keys immediately upon receipt and ensure the mechanism is smooth. The integrated sliding dust cover is another standout feature, protecting the cylinder from the dirt and grime of daily use, which is crucial for maintaining that smooth operation for years to come.
Living with the Legend: Practicality, Portability, and Daily Use
Let’s be unequivocally clear: the Kryptonite New York Legend 1515 Bike Chain Lock 5 Feet is a heavyweight champion, and it has the weight to prove it. At 14.7 pounds, this is not a lock you casually toss in a backpack for a ride across town. We found it is best utilized as a “destination lock.” It’s the perfect solution to leave at your office, in your home garage, or at any primary location where you regularly park your bike for extended periods. For motorcycle and scooter users with storage compartments, carrying it is more feasible, but for the average cyclist, portability is its greatest challenge.
However, where it sacrifices portability, it delivers unparalleled versatility. The 5-foot length is a game-changer. Throughout our testing, we never encountered a situation where we couldn’t find a secure locking point. We were able to easily loop it through the bike frame, the rear wheel, and around thick signposts, parking meters, and awkwardly shaped bike racks that stymied shorter U-locks. This length gives you the power to secure your bike properly—to an unquestionably immovable object—every single time. The thick, durable nylon cover proved its worth repeatedly. It made handling the heavy chain much more comfortable and, critically, it completely protected our bike’s expensive paint job from getting scratched or chipped during the locking process. It’s a small detail that demonstrates a deep understanding of a rider’s needs.
What Other Users Are Saying
Our positive experience with the sheer security of the Kryptonite New York Legend 1515 Bike Chain Lock 5 Feet is strongly echoed in user feedback. The prevailing sentiment is one of ultimate confidence. Buyers frequently use words like “massive,” “heavy,” and “beast” to describe it, noting that its imposing presence is well worth the price for the peace of mind it provides. One user captured this perfectly, stating, “I don’t think I’ll have an issue with theft,” and praised the well-made construction and easy-to-handle cloth cover.
However, a recurring and important point of caution emerges regarding the condition of the product upon arrival. A couple of users reported paying for a new lock but receiving a unit that was clearly used, with heavy wear on the lock body and keys that did not insert or turn easily. This feedback is invaluable, as it highlights a potential issue with fulfillment from some online sellers. It serves as a crucial reminder for any prospective buyer to thoroughly inspect their lock immediately upon delivery and to test the key mechanism to ensure it operates as smoothly as our test unit did. Any issues should be addressed immediately with the seller for a return or exchange.
How Does the Legend 1515 Stack Up? A Competitive Showdown
No product exists in a vacuum. To truly understand the value and positioning of the Kryptonite New York Legend 1515 Bike Chain Lock 5 Feet, it’s essential to compare it against notable alternatives that cater to different needs and priorities.
1. Kryptonite Keeper 712 4 Feet Bike Chain Lock
- HEAVY-DUTY CHAIN: Made from 7mm hardened steel with four-sided links, this bike lock provides maximum resistance against cutting and leverage attacks
- PATENTED LOCKING SYSTEM: Features a high-security disc-style cylinder, resistant to picking and drilling, and a patented end link design that securely connects the chain to a hardened deadbolt,...
- PROTECTIVE FEATURES: Durable rubber coating around helps prevent scratching and wear and tear on your bike. Durable WEATHER-RESISTANT nylon sleeve prevents scratches
The Kryptonite Keeper 712 is best viewed as the Legend’s lighter, more approachable sibling. Its primary advantage is portability; it’s significantly lighter and easier to carry than the Legend 1515. However, this comes at the direct cost of security. The Keeper uses 7mm four-sided chain links, which offer solid protection against hand tools in low-to-moderate risk areas but are no match for the 15mm links of the Legend when faced with a determined, well-equipped thief. The Keeper 712 is an excellent choice for a secondary lock, for securing a less expensive bike, or for use in safer suburban environments. For anyone securing a high-value e-bike or motorcycle overnight in a city, the Legend 1515 is in a completely different league of protection.
2. ABUS 2′ Hardened Steel Security Chain

- Anti Theft Design: This chain features square shaped links, much more effective against attacks with tools; The chains also feature a nylon sleeve to prevent scratches and damage to paint work and...
- Padlocks for Any Application: Discover the variety of our padlocks, from heavy duty Granit padlocks and disc locks to brass, steel and aluminum models, to resettable combination, rekeyable and keyed...
The ABUS 10KS Security Chain represents a different approach. It is sold as a chain only, requiring you to supply your own high-security padlock. This offers flexibility but also adds an extra purchasing step. At 10mm, its square links are tougher than the Keeper’s but still fall short of the Legend’s 15mm round links. Its most significant limitation is its very short 2-foot length, which severely restricts what you can lock your bike to. This ABUS chain is better suited for specific industrial applications or for securing items in a tight space, like a generator to a truck bed. For the versatility needed to secure a bicycle or motorcycle to various urban fixtures, the Legend’s generous 5-foot length is far superior.
3. Seatylock FoldyLock Elite Folding Bike Lock High Security
- 3 YEAR PEACE OF MIND SUPER STRONG BIKE LOCK WITH KEY - Portable & Solid Bike Lock. No Codes Cable or Chain. For Outdoor & Urban Cycling. Best Bike Lock. Bolt Cutter & Saw Proof to Stop Thieves
- LONGEST & STRONGEST 18/18 SECURITY LEVEL SOLD SECURE GOLD - 6.5mm Hardened Steel Plates for Maximum Bike Protection. AntiTheft Security for Safe Cycles Outside. Top Rated Pro Safety Tool Electric Bike...
- WORLD'S ONLY ART 3 STARS CERTIFIED FOLDING BIKE LOCKS HEAVY DUTY ANTI THEFT - Anti Tamper Rivets with Strong Guard System for Side Attacks. Unbreakable Waterproof Weatherproof Bicycle Protector
The FoldyLock Elite is a brilliant piece of engineering that directly addresses the Legend’s primary weakness: portability. It provides an impressive Sold Secure Gold security rating in a compact, foldable package that can be easily mounted to the bike’s frame. It’s an innovative solution for the security-conscious rider who cannot or will not carry a 15-pound chain. The trade-off is in its form factor. While strong, the rigid links of a folding lock offer less flexibility than a chain for wrapping around bulky or awkwardly shaped objects. The FoldyLock Elite is the perfect choice for the rider who needs high security on the go, while the Legend 1515 remains the undisputed king for stationary, maximum-security applications where weight is not a factor.
The Final Word: Is the Kryptonite New York Legend 1515 the Right Lock for You?
After extensive hands-on testing, we can say with confidence that the Kryptonite New York Legend 1515 Bike Chain Lock 5 Feet is not just a lock; it’s a security anchor. It is one of the most formidable, intimidating, and robust consumer-grade security chains on the market today. Its massive 15mm hardened steel links and high-performance disc lock create a defensive system that will defeat all but the most audacious and prepared thieves. The generous 5-foot length provides the flexibility to secure your ride almost anywhere.
However, its greatest strength is intrinsically linked to its greatest weakness: its extreme weight. This is not a lock for everyone. It is purpose-built for those who cannot compromise on security. We wholeheartedly recommend it for owners of expensive e-bikes, motorcycles, and premium bicycles who need to leave their prized possessions unattended for long hours or overnight in high-risk urban areas. Think of it as the ultimate “at home” or “at work” lock, a permanent fixture that guarantees your ride is waiting for you when you return. If your security needs are absolute and portability is a secondary concern, there is simply no substitute for the peace of mind this legend provides.
