There are few feelings as gut-wrenching as walking out to the spot where you left your motorcycle, your pride and joy, only to find an empty patch of pavement. Your heart plummets, a cold sweat breaks out, and your mind races. It’s a scenario we riders and cyclists dread, a violation that’s more than just the loss of property; it’s the theft of freedom, of passion, of countless hours of care and investment. In that moment, you’d give anything for a second chance to have secured it better. This is the very real fear that drives us to seek out security solutions that don’t just lock our bikes, but that scream “don’t even think about it” to any would-be thief. The search for peace of mind leads us to heavy-duty hardware, and the BIGLUFU Heavy Duty Motorcycle Chain Lock 150cm is a product that, by its sheer presence, promises to be that formidable guardian. We decided to put that promise to the test.

What to Look for Before Entrusting Your Bike to a Chain Lock
A bike chain lock is more than just an item; it’s a key solution for asset protection and a powerful deterrent against theft. It’s the physical barrier between your valuable motorcycle, e-bike, or generator and a criminal looking for an easy score. The primary benefit is straightforward: to make the act of stealing your property so difficult, time-consuming, and noisy that a thief will simply give up and move on to an easier target. It offers a level of physical resistance that cable locks simply cannot match and a flexibility in application that rigid U-locks sometimes lack, allowing you to secure your asset to a wide variety of anchor points like posts, railings, and trees.
The ideal customer for this type of product is someone who parks their motorcycle or high-value bicycle in a semi-public or vulnerable location for extended periods. This includes commuters, apartment dwellers without access to a private garage, and anyone storing equipment like generators or grills outdoors. It’s for the owner who understands that security is about creating layers of difficulty. Conversely, this type of heavy-duty chain lock might not be suitable for those who prioritize portability above all else, like a road cyclist who needs to minimize every ounce of weight. For them, a lighter, more compact U-lock or folding lock might be a better compromise. However, for stationary security or when transporting the lock via a vehicle, the heft of a heavy-duty chain is a feature, not a bug.
Before investing, consider these crucial points in detail:
- Chain Link Thickness & Shape: This is arguably the most important factor. Look for chains with links at least 10mm thick, made from hardened steel. The BIGLUFU Heavy Duty Motorcycle Chain Lock 150cm boasts 12mm square-linked steel, which is significantly more difficult for bolt cutters to bite into compared to round links. The thicker the link, the more resistant it is to cutting attacks.
- Length and Versatility: The length of the chain determines what you can lock your bike *to*. A shorter chain might only go around your wheel and frame, while a longer one, like this 150cm (5ft) model, provides the flexibility to anchor your bike to thick lamp posts, trees, or even to another motorcycle. Consider your typical parking scenarios to decide on the optimal length.
- Materials & Durability: The material is paramount. Look for specific callouts like Manganese Steel or Boron alloys, which are hardened to resist attacks. The lock itself should also be made of hardened steel. Pay attention to protective coatings; a good nylon or fabric sleeve prevents the heavy chain from scratching your bike’s paint and finish.
- Lock Mechanism & Key Security: The chain is only as strong as the lock that secures it. A high-quality disc detainer or dual-locking shackle U-lock offers superior resistance to picking, pulling, and leverage attacks. Also, consider the number of keys provided; having spares is essential. The BIGLUFU includes four keys, which is a generous and practical touch.
Understanding these elements will empower you to choose a security system that not only fits your needs but gives you genuine confidence when you walk away from your ride.
While the BIGLUFU Heavy Duty Motorcycle Chain Lock 150cm 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:
- HEAVY-DUTY CHAIN: Made from 7mm manganese steel with four-sided links, this bike lock provides maximum resistance against cutting and leverage attacks
- High Security & Keyless Design: Say goodbye to the hassle of carrying keys and hello to keyless convenience. The advanced 5-digit combination lock offers unparalleled protection, with up to 100,000...

First Impressions: Unboxing a Nearly 10-Pound Beast of a Deterrent
The first thing you notice upon receiving the BIGLUFU Heavy Duty Motorcycle Chain Lock 150cm is the weight. At 9.9 pounds, this is not a lock you casually toss in a backpack. The heft is substantial and immediately communicates a sense of seriousness. Unboxing it, the chain coils with a satisfyingly heavy “clank.” The 12mm square-linked manganese steel chain feels incredibly robust in your hands, far more intimidating than the typical hardware store chain. It’s wrapped in a thick, tightly woven nylon sleeve, which we found effectively protects the bike’s frame and wheels from scratches during use—a crucial detail for any rider who cares about their paint job.
The accompanying U-lock is similarly hefty, with a 14mm shackle coated in a thick PVC layer. It feels solid, though as some users noted, the body of the lock has some plastic components that feel less premium than the chain itself. The locking mechanism is key-operated, and the inclusion of four keys is a very welcome feature, saving the immediate worry of loss or the need for costly replacements. Compared to some integrated chain locks from premium brands, the two-piece design (separate chain and U-lock) offers a bit more versatility in how you apply it, though it can be slightly more cumbersome to handle. Our initial impression is one of brute force; this lock is designed to be a powerful visual and physical deterrent, and its imposing presence alone is a key feature.
Key Benefits
- Extremely thick 12mm square-linked manganese steel chain offers high resistance to bolt cutters.
- Generous 150cm (5ft) length allows for securing to a wide variety of fixed objects.
- Substantial weight and appearance act as a strong visual deterrent to opportunistic thieves.
- Protective nylon sleeve prevents scratches on the motorcycle or bike frame.
Limitations
- The included U-lock is the weakest component and is vulnerable to angle grinders.
- Very heavy (9.9 lbs), making it impractical for daily carry unless transported in a vehicle.
Performance Under Pressure: A Deep Dive into the BIGLUFU Lock’s Real-World Security
A lock’s true worth is only revealed when it’s put to the test, both in daily use and under the threat of attack. We spent weeks using the BIGLUFU Heavy Duty Motorcycle Chain Lock 150cm in various scenarios, from securing a motorcycle overnight in an apartment complex parking lot to locking down a high-end e-bike outside a coffee shop. Our analysis focuses on the three core components of the experience: the chain’s integrity, the lock’s functionality, and the overall practicality of this heavyweight system.
The Heart of the System: Analyzing the 12mm Manganese Steel Chain
Let’s be unequivocally clear: the star of this show is the chain. The 12mm (0.47-inch) thick, square-linked 3T manganese steel is formidable. Holding it, you understand why it’s rated to withstand 8KN of tension and 17KN of shear force. The square profile of the links is a critical design choice. Unlike round links, which give the jaws of a bolt cutter a convenient place to bite, square links force the jaws to slip or apply pressure at an awkward angle, dramatically increasing the force required to make a cut. During our testing, we found it impossible to defeat with standard-sized bolt cutters.
This finding is directly corroborated by user experiences. One user reported that a thief attempted to cut the chain and failed, leaving behind only superficial marks. This is the exact scenario this chain is built for: to defeat the common, opportunistic thief. The psychological impact is just as important. The sound of this chain being draped around a bike’s frame and a solid anchor point is a statement. It’s a heavy, authoritative sound that signals this is not an easy target. As one user aptly put it, it’s a “Big ole deterrent.” Another shared a story where thieves started to remove tie-down straps from his mini-bike on a car trunk, noticed the BIGLUFU chain, and abandoned their efforts. This is a testament to the power of visual deterrence, and this lock’s ability to intimidate is one of its greatest assets. The chain is, without a doubt, the high point of this security package and worth the price of admission on its own.
Practicality in Practice: The 150cm Length and Daily Use
Security is useless if it’s too inconvenient to use. Here, the BIGLUFU Heavy Duty Motorcycle Chain Lock 150cm presents a duality. Its greatest strength in versatility—the 5-foot length—is directly tied to its greatest weakness in portability—the 9.9-pound weight. The length is fantastic. We had no trouble finding secure anchor points, easily looping the chain through the motorcycle frame, the rear wheel, and around thick concrete pillars in a parking garage. It’s long enough to secure two bicycles together or to lock a generator to a fence post with room to spare. The protective nylon sleeve did its job perfectly, preventing any nicks or scratches on our bike’s swingarm and wheels, and it held up well to being dragged on concrete and asphalt.
However, this is not a lock you carry with you on a ride unless you have panniers, a top case, or are simply transporting it in a car. It’s far too heavy and bulky to wear or carry in a standard backpack. For this reason, we see it as an ideal “destination lock.” It’s perfect for securing your bike at home, at your workplace, or in any situation where you can leave the lock behind. One user, a travel nurse who hauls her bike everywhere, found it perfect for securing her bike overnight where she was parked, confirming its suitability for stationary, high-risk situations. If you need a lock for quick stops or one to carry on your person, this isn’t it. But for overnight security or locking up for a full workday, its heft and length provide unmatched flexibility and peace of mind.
The Achilles’ Heel? A Critical Look at the U-Lock Mechanism
While the chain is a fortress, the security system is only as strong as its weakest link, and in this case, that appears to be the U-lock itself. While its 14mm shackle is thick, several user reports, and our own observations, raise concerns about its overall construction and resilience against more sophisticated attacks. Several users noted that the lock’s body feels plasticky and fragile. We encountered some initial stickiness with the key mechanism, confirming one user’s report that they had to “play around with the key to get it to lock again.” While it functioned, it didn’t inspire the same level of confidence as the chain.
More alarmingly, multiple users reported catastrophic failures of the lock. In one harrowing account, a thief failed to cut the chain but successfully cut through the U-lock with a grinder or saw, stealing the bike. Another user’s bike was stolen within a week, with the lock appearing to have been defeated quickly. This highlights a critical vulnerability: angle grinders. While the chain may hold up for a decent amount of time against a grinder, a determined thief will often attack the lock body itself, which can be a faster point of failure. The consensus among many who have used this product long-term is clear: the chain is excellent, but the lock is merely adequate. For low-to-medium risk areas, the included lock is a sufficient deterrent. However, if you park in a high-theft area like downtown Denver, as one user did, we strongly recommend purchasing the BIGLUFU Heavy Duty Motorcycle Chain Lock 150cm for its superb chain and pairing it with a higher-security, name-brand U-lock or disc lock for ultimate protection.
What Other Users Are Saying
Synthesizing feedback from numerous buyers reveals a distinct pattern. On the positive side, users are consistently impressed by the sheer physicality of the chain. Phrases like “worth every penny,” “very strong, and very Heavy,” and “you won’t be disappointed” are common. Many purchase it specifically as a visual deterrent, and it succeeds admirably in that role. One user was ecstatic, stating, “This 60$ chain saved my bike,” after would-be thieves were spooked by its presence. This confirms our assessment that its primary function as an intimidating object is highly effective against casual criminals.
However, the negative feedback is just as consistent and centers almost exclusively on the lock. Reports of the “lock look very plastic and fragile” and keys jamming or spinning freely are frequent. The most damning reviews come from those who had their property stolen, with a clear theme emerging: the thieves bypassed the formidable chain and attacked the lock. “Thief attempted to cut the chain and failed. However they moved to the lock and was able to cut through it,” one user lamented. Another stated bluntly, “The chain seems very sturdy, but that’s no good if the locking mechanism can be cut.” This creates a balanced, if cautionary, picture: you are buying a top-tier chain bundled with a mid-tier lock.
How Does the BIGLUFU Stack Up Against the Competition?
No product exists in a vacuum. To truly understand the value proposition of the BIGLUFU Heavy Duty Motorcycle Chain Lock 150cm, it’s essential to compare it to other popular options on the market. We’ve selected three key alternatives that cater to different needs and budgets.
1. AMZLOCK Heavy Duty Chain Lock for Scooter
- DURABLE ALLOY STEEL CHAIN: Features a solid 5/16" thick high-strength alloy chain for reliable security. With a total weight of 4 lbs, its heavy-duty construction acts as a strong visual and physical...
- SURFACE-SAFE DESIGN: The lock head is covered in soft rubber and the chain is fully encased in a protective fabric sleeve. This thoughtful design helps prevent scratches and paint damage to your...
- PRACTICAL & CONVENIENT LENGTH: Measuring 29.5 inches, this chain offers a great balance between reach and portability. It provides ample length to secure your vehicle to various anchor points like...
The AMZLOCK is positioned for a different user entirely. With a much shorter length (29.5 inches) and a thinner 8mm (5/16″) chain, it’s significantly lighter and more portable than the BIGLUFU. This makes it a suitable choice for securing electric scooters or bicycles in lower-risk environments or for quick stops where convenience is key. However, its 8mm chain does not offer the same level of resistance against serious bolt cutters as BIGLUFU’s 12mm beast. Someone might prefer the AMZLOCK if their primary need is a simple, lightweight deterrent for a less valuable asset, and they prioritize portability over maximum security.
2. Kryptonite 1016 Evolution Integrated Bike Chain 5.25 ft
- 10mm six-sided chain links made from 3T MANGANESE STEEL
- Patent-pending END LINK DESIGN secures chain to hardened deadbolt eliminating critical vulnerability
- HIGH SECURITY DISC-STYLE CYLINDER is pick and drill resistant
Kryptonite is a titan in the security industry, and the 1016 Evolution is a direct competitor. It features a slightly thinner 10mm chain but benefits from Kryptonite’s legendary lock engineering, with the locking mechanism integrated directly into the final link. This design eliminates the shackle as a point of attack. While the BIGLUFU’s chain is technically thicker (12mm vs 10mm), many users would trade that 2mm for the peace of mind that comes with a Kryptonite lock cylinder. A rider who values a proven, balanced system from a top-tier brand and is wary of the potential weakness in the BIGLUFU’s separate U-lock would likely prefer the Kryptonite Evolution.
3. Kryptonite New York 1210 Bike Chain Lock
- HEAVY-DUTY CHAIN: Made from maximum strength 12mm 3T Hardened Manganese Steel Chain, the six-sided chain links provide ultimate cut resistance. Paired with a durable nylon cover and hook-and-loop...
- EVOLUTION SERIES 4 DISC LOCK INCLUDED: Features a 14mm max-performance steel shackle and patented oval hardened steel crossbar for ultimate anti-theft protection
- DOUBLE DEADBOLT & HIGH-SECURITY CYLINDER: Hardened double deadbolt locking mechanism and disc-style cylinder offer strong resistance against pulling, drilling an picking
This is the nuclear option in portable security. The Kryptonite New York 1210 features a 12mm chain, matching the BIGLUFU’s thickness, but pairs it with an Evolution series disc lock that carries a Sold Secure Gold rating—an independent certification of high security. This system is designed to withstand the most determined attacks in the highest-risk urban environments. It is, however, significantly more expensive and shorter (3.25 ft). A user should choose the New York 1210 if their bike is parked in a known high-theft area, insurance requires a certified lock, and budget is secondary to achieving the absolute highest level of tested and proven security.
Final Verdict: A Formidable Chain That Deserves a Better Partner
After extensive testing and analysis, our verdict on the BIGLUFU Heavy Duty Motorcycle Chain Lock 150cm is nuanced. This product is, first and foremost, an exceptional value for the chain alone. The 12mm, 5-foot-long manganese steel chain is an absolute beast that will defeat opportunistic thieves with bolt cutters and will serve as a powerful visual deterrent that can’t be overstated. For many users in low-to-medium risk areas, the entire system as-is will provide more than enough security and peace of mind.
However, we cannot ignore the consistent and credible reports of the included U-lock being the system’s critical weak point. It simply does not match the formidable security of the chain it’s meant to anchor. Therefore, we recommend this product with a condition: if you are securing a high-value motorcycle or e-bike in an area where determined, tool-equipped thieves are a concern, you should view this purchase as buying a fantastic chain and plan to replace the included U-lock with a higher-grade model from a reputable brand. For the price, you are getting a chain that competes with those from far more expensive packages, making it a smart buy for the discerning consumer who understands its limitations. If you’re looking for a heavy-duty chain that offers incredible deterrence and resistance to cutting, the BIGLUFU Heavy Duty Motorcycle Chain Lock 150cm is an outstanding foundation for a truly robust security setup.
