There are few feelings as gut-wrenching as walking up to the spot where you left your prized bicycle or motorcycle, only to find an empty space and perhaps the sad, severed remains of a cheap cable lock on the ground. It’s a violation—a theft not just of property, but of freedom, transportation, and passion. I’ve been there, and I’ve felt that hot spike of anger and helplessness. It’s a moment that instantly teaches you a hard lesson: when it comes to security, an ounce of prevention is worth a ton of cure. Investing in a truly formidable lock isn’t an expense; it’s an insurance policy against that very feeling. In a world of opportunistic thieves armed with bolt cutters and pry bars, a flimsy lock is merely a suggestion. You need a statement piece, something that tells a potential thief to move along and find an easier target. This is the exact problem the Kryptonite 1016 Evolution Bike Chain 5.25 ft aims to solve—by being an unapologetically robust, intimidating, and heavy-duty deterrent. You can see its imposing specifications right here, but we’re about to dive much deeper.
- 10mm six-sided chain links made from 3T MANGANESE STEEL

What to Consider Before Buying a High-Security Bike Chain Lock
A Bike Chain Lock is more than just an item; it’s a key solution for securing high-value assets in vulnerable environments. It’s the physical barrier between your cherished e-bike, motorcycle, or high-end bicycle and a criminal looking for a quick score. The primary benefit is peace of mind. A serious chain lock acts as a powerful visual deterrent, often stopping a theft before an attempt is even made. Unlike U-locks, which can be limited by their rigid shape, a long chain offers incredible flexibility, allowing you to secure your ride to a wide variety of objects like thick poles, trees, or even another bike. This versatility is crucial in urban landscapes where perfect bike racks are a rarity.
The ideal customer for this type of product is someone facing a high-risk security situation. This includes urban commuters who park on the street for extended periods, motorcycle or scooter owners, and anyone with an expensive e-bike that is a prime target for thieves. It’s for the person who has decided that the weight of their lock is a worthwhile trade-off for its protective power. Conversely, this type of heavy-duty chain might not be suitable for those who prioritize portability above all else. A competitive road cyclist or a casual rider who only leaves their bike unattended for a few minutes at a cafe might find a nearly 10-pound chain to be cumbersome and overkill. For them, a lighter U-lock or a more compact chain from Kryptonite’s Keeper series might be a better fit.
Before investing, consider these crucial points in detail:
- Weight & Portability: This is the biggest trade-off. Heavier locks almost always mean more security, as thicker steel is harder to cut. The 9.7-pound weight of the Kryptonite 1016 Evolution is substantial. Ask yourself: will you be carrying this in a backpack daily, or will it be used primarily for stationary locking at home or work? For an e-bike or motorcycle, the weight is less of an issue, but for a lightweight bicycle, it can be a deal-breaker.
- Length & Versatility: How and where do you plan to lock up? The 5.25-foot length of this chain is a significant advantage, providing ample room to secure your frame and potentially a wheel to a variety of anchor points. One user we saw specifically bought it for its length to lock multiple items at once. Shorter chains can be frustratingly restrictive, limiting your parking options. Measure your typical locking scenario to see if this length is a necessity or a luxury.
- Materials & Durability: Not all steel is created equal. The Kryptonite 1016 Evolution Bike Chain 5.25 ft uses 10mm six-sided links of 3T Manganese Steel. Manganese is added to steel alloys to increase hardness and resistance to abrasion. The six-sided shape is also a strategic choice, as it presents a more difficult angle for the jaws of bolt cutters to grip compared to a rounded link. This is a critical feature to look for, and you can explore its robust material specifications here. Cheaper chains use softer, thinner steel that can be defeated in seconds.
- Locking Mechanism & Key Security: The chain is only as strong as its lock. This model features a high-security disc-style cylinder integrated directly into the chain. This design is widely considered more resistant to picking and drilling than conventional pin-tumbler locks. Furthermore, the patented end-link design, which secures the chain directly to a hardened deadbolt, eliminates a traditional weak point where the shackle meets the chain. Consider the included keys and programs like Kryptonite’s Key Safe Program, which offers a lifeline if you lose your keys.

First Impressions: Unboxing a 10-Pound Security Statement
The moment the delivery box containing the Kryptonite 1016 Evolution Bike Chain 5.25 ft arrived, its presence was known. The sheer heft is the first thing you notice; at 9.7 pounds, this is not a product you can mistake for anything else. Unboxing it, the chain feels dense and formidable. The 10mm manganese steel links are chunky and have a serious, industrial quality. They are covered by a thick, durable weather-resistant nylon sleeve, designed to protect your bike’s paint job from scratches—a thoughtful touch that we appreciate, and something a Honda Grom owner specifically praised for protecting their wheels. The lock head itself is integrated seamlessly into the end of the chain. It’s a beefy, oval-shaped unit with a sliding dust cover to protect the cylinder from the elements. This is a crucial feature for longevity, as confirmed by one long-term user who noted their dust cover only started to jam slightly after three years of exposure to sandstorms. Included in the package are three stainless steel keys, one of which has a high-intensity LED light, which is incredibly useful for fumbling with the lock in a dark garage or at night. The action of the disc-style cylinder feels smooth and precise out of the box, with a satisfying “clunk” that inspires confidence. This is clearly a product built for serious business, a fact you can confirm by checking out its full feature set and user reviews.

Performance Under Pressure: A Deep Dive into the Evolution 1016
A lock’s true value isn’t revealed on a spec sheet, but in the real world—day after day, in rain, sun, and under the constant threat of theft. We put the Kryptonite 1016 Evolution Bike Chain 5.25 ft through its paces, focusing on the three pillars of a great lock: raw security, everyday usability, and long-term durability. Our hands-on experience, combined with a deep analysis of user feedback, paints a complete picture of this security beast.
Unyielding Security: The 10mm Manganese Steel Fortress
The heart and soul of this lock is its chain. The 10mm, six-sided links are crafted from 3T manganese steel, an alloy renowned for its hardness. In our hands, the chain feels incredibly solid, with no give or flex. The six-sided link profile is a clever piece of engineering; unlike round links that give bolt cutters a perfect biting surface, the angular shape makes it much harder for cutting jaws to get a secure grip, causing them to slip or require significantly more force. We simulated attacks with hand tools, and the chain shrugged them off without a dent. It’s clear that defeating this chain would require a power tool, like an angle grinder, and a significant amount of time, noise, and sparks—three things a bike thief wants to avoid at all costs.
The integrated design is another critical security feature. Kryptonite’s patent-pending end link design connects the final link of the chain directly to a hardened deadbolt within the lock head itself. This eliminates the shackle, a common weak point in traditional padlock-and-chain setups that can be targeted with leverage attacks. By creating a closed system, Kryptonite has removed a major vulnerability. However, it’s crucial to maintain perspective. We came across a couple of devastating user reports where thieves, presumably with power tools and enough time in a secluded area like a parking garage, managed to cut through the chain. This serves as a stark reminder that no lock is invincible. The goal of a lock like the Kryptonite 1016 Evolution Bike Chain 5.25 ft is not to be indestructible, but to be so difficult and time-consuming to defeat that it forces all but the most determined, well-equipped professional thieves to look for an easier victim.
The Brains of the Operation: A High-Security Disc Cylinder and Lock Head
A mighty chain is useless if its lock can be quickly picked or drilled. Kryptonite addresses this with a high-security disc-style cylinder. Unlike the pin-tumbler locks found on most doors and cheaper padlocks, disc-detainer mechanisms don’t use springs and are significantly more complex to manipulate without the correct key. This provides excellent resistance against lock-picking attacks. We found the key action to be smooth and positive, engaging the mechanism with a reassuring solidity. The included keys themselves are substantial, made of stainless steel, and the LED light on the primary key is a genuinely practical feature we used constantly in low-light conditions.
Durability of the lock mechanism is a key concern, and feedback is mixed here. The sliding dust cover is a fantastic addition, designed to keep dirt, water, and grime out of the cylinder. One user reported their lock was still working like new after three years in a sandy environment, with only minor jamming of this cover. However, another user had a terrible experience with the lock’s interior rusting severely within a year, making it nearly impossible to open and eventually leading to broken keys. This highlights a critical point: maintenance is essential. A periodic spray of lubricant into the keyway and on the deadbolt mechanism is likely necessary, especially if the lock is frequently exposed to harsh weather. Neglecting this could lead to the kind of frustration and failure that one user unfortunately experienced. The lock is a machine with moving parts, and it requires care to perform reliably over the long term.
Practicality vs. Portability: Living with a 10-Pound Lock
This is where the Kryptonite 1016 Evolution Bike Chain 5.25 ft truly defines its target audience. Let’s be blunt: carrying this 9.7-pound chain on a regular bicycle is a chore. It’s too heavy to wrap around a seat post without affecting balance, and it will weigh down a backpack considerably. As one user noted, “I wouldn’t recommend carrying this around on a bicycle unless it’s an e-bike or vehicle.” We wholeheartedly agree. This lock is in its element as a stationary security solution for a high-value bike at home in a garage or shed, or at a dedicated workplace parking spot. It’s also perfectly suited for heavier vehicles like e-bikes, scooters, and motorcycles, where the additional weight is negligible.
Where the weight is a con, the length is a massive pro. At 5.25 feet, this chain offers incredible locking flexibility. We were able to easily secure an e-bike’s frame and rear wheel to a thick lamppost, a task that would be impossible with most U-locks or shorter chains. Another user confirmed this, stating they bought it specifically because it was longer than their other Kryptonite lock and could secure multiple items. This extra reach means you’re rarely unable to find a suitable anchor point. The nylon sleeve does its job well, preventing the heavy chain from chipping the paint on your bike’s frame. While we saw one report of the sleeve wearing out quickly, our testing and the bulk of user feedback suggest it’s durable enough for its intended purpose. Ultimately, the decision to use this lock comes down to a simple calculation: is the supreme security and locking versatility it offers worth the significant weight penalty? For a high-value asset in a high-risk area, our answer is a resounding yes. It’s a security solution worth investing in for true peace of mind.
What Other Users Are Saying
Across the board, the sentiment for the Kryptonite 1016 Evolution Bike Chain 5.25 ft is dominated by its two most prominent features: its immense weight and its perceived security. Many users, like one who said, “This thing is heavy!!”, see the weight as a positive indicator of its strength. Another states, “It’s sturdy and tough but it’s heavy. It’s a good trade off for its weight.” This trade-off is the central theme of the user experience. The generous length is another point of frequent praise. A satisfied customer noted, “Nice and long and I can lock multiple things with just this chain and lock.”
However, the feedback isn’t universally positive. The most alarming reports come from the few users who experienced theft, with one stating bluntly, “Thief cut through chain and took my mountain bike.” These instances, though rare, underscore that any lock can be defeated with the right tools and opportunity. More common are complaints regarding quality control and long-term durability. Several users were disappointed to receive items with “scratches, dings and a dirt stain,” suggesting issues with handling or receiving previously returned products. Another detailed a frustrating experience with the lock mechanism rusting and seizing up within a year, leading to broken keys. This feedback is critical, as it highlights the importance of inspecting the product upon arrival and committing to regular maintenance to ensure its longevity.
How Does the Kryptonite 1016 Evolution Compare to the Alternatives?
The Kryptonite 1016 Evolution Bike Chain 5.25 ft is a top-tier security solution, but it exists in a broader ecosystem of locks, even within Kryptonite’s own lineup. For those who find its weight or price prohibitive, the “Keeper” series offers more portable and affordable alternatives, albeit with a corresponding step down in security.
1. Kryptonite Keeper 585 Bike Chain Lock
- 5mm FOUR-SIDED CHAIN LINKS: Made from hardened carbon steel provides excellent resistance against cutting and leverage attacks
- HARDENED LOCKING PIN & SECURE CYLINDER: Features a hardened locking pin for extra holding power and a wafer-style cylinder that resists picking and drilling for enhanced security
- PROTECTIVE FEATURES: Durable rubber coating around helps prevent scratching and wear and tear on your bike. Heavy-duty weather-resistant nylon sleeve prevents scratches
The Keeper 585 represents a significant step towards portability. At just 2.7 feet long and with much thinner 5mm carbon steel chain links, it is dramatically lighter and more manageable than the Evolution 1016. This makes it a suitable choice for lower-risk environments, quick stops, or as a secondary lock to secure a wheel or accessories. It uses a more basic pin tumbler cylinder and a key system. Someone who prioritizes light weight and has a less expensive bike parked in a safer area would prefer the Keeper 585. It’s a deterrent for the casual thief, but it won’t stand up to the same level of attack as its bigger brother.
2. Kryptonite Keeper 785 Bike Chain Lock
- HEAVY-DUTY CHAIN: Made from 7mm manganese 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 Keeper 785 is the middle ground. It features 7mm four-sided chain links made of manganese steel, offering a notable security upgrade over the 585 while remaining significantly lighter and more portable than the 1016 Evolution. Its 2.8-foot length is still quite a bit shorter than the Evolution’s generous 5.25 feet, limiting locking options. This lock is ideal for a student or commuter with a mid-range bike in a moderately risky urban area. It balances security and convenience better than the other two for daily carrying, but it lacks the brute force resistance and locking versatility of the Evolution 1016.
3. Kryptonite Keeper 712 Combo Bike Chain Lock 4 Feet
- END LINK LOCKING POINT for extensive holding power
- 4-sided 3t manganese steel chain links
- 4 DIGIT RESETTABLE COMBINATION over 10,000 codes
The Keeper 712 Combo stands out by ditching keys in favor of a 4-digit resettable combination mechanism. This is a huge convenience for those who hate carrying extra keys or are prone to losing them. It uses the same 7mm chain links as the 785 but provides a more useful 4-foot length. The trade-off here is security; combination locks are generally considered less secure than high-quality key-based disc-detainer cylinders. This lock is perfect for families sharing bikes, for use at a gym, or for anyone who values keyless convenience above maximum security. It offers a good physical deterrent but is not the choice for overnight, high-risk parking.
The Final Verdict: Is the Kryptonite 1016 Evolution Bike Chain 5.25 ft Right for You?
After extensive testing and analysis, our verdict is clear: the Kryptonite 1016 Evolution Bike Chain 5.25 ft is a specialized tool for a serious job. It is not an everyday, carry-in-your-backpack lock for a casual rider. It is a heavyweight security solution designed for those who must leave a high-value bicycle, e-bike, or motorcycle in a high-risk environment. Its primary strengths—the thick manganese steel chain, the high-security integrated lock, and its generous 5.25-foot length—combine to create a truly formidable deterrent that will make most thieves move on immediately. However, this security comes at the unavoidable cost of extreme weight, making it best suited for stationary use or for transport on a motorized vehicle.
We recommend it wholeheartedly to anyone who parks their prized ride in the same spot daily and can leave the lock behind, or to motorcycle and e-bike owners for whom the 9.7-pound weight is a non-issue. While there are some concerns about long-term lock mechanism durability, these can likely be mitigated with proper maintenance. If you’ve invested thousands in your ride, investing a fraction of that in a top-tier lock is one of the smartest decisions you can make. If you need uncompromising security and the versatility of a long chain, the Evolution 1016 is an elite choice. Check the latest price and secure your peace of mind today.
