Our Picks at a Glance
How To Choose The Best Motorcycle Chain Lock
The right motorcycle chain lock is a balance of three things: how hard it is to cut, how easy it is to carry, and how well it fits your specific bike and typical parking spots. Once you know what to look for in each area, the decision gets much simpler.
Chain Thickness and Material
The thickness of the chain links, measured in millimeters, is your first line of defense. A 10mm chain is a solid starting point for most city parking, while a 12mm chain moves into serious deterrent territory. The material matters just as much—3T manganese steel and hardened alloy steel are dramatically harder to cut through than standard steel. A thick, hardened chain forces a thief to use noisy power tools, which is the best visual and audible deterrent you can buy.
Length and Weight
Longer chains give you more flexibility—you can wrap them around a thick lamppost, thread them through both wheels and the frame, or even secure two bikes together. But that extra length comes in pounds. A 3-foot chain is light enough to toss in a backpack or wrap around the frame. A 6-foot chain might be what you need for a truck bed or a parking lot, but you will feel the heft in your bag every day. Pick the shortest chain that still covers your typical locking scenarios, to keep the carry weight manageable.
Lock Cylinder and Key Design
A strong chain is useless if the lock itself is weak. The best locks use a disc-style cylinder (a round, reinforced core) that resists picking, drilling, and prying. Look for a dust cover over the keyhole too—it keeps dirt, rain, and grime out of the cylinder, which prevents the lock from jamming over time. Keys made from brass or stainless steel are more durable than standard pot-metal keys, and having three or four spares means you can always keep one in your jacket.

In‑Depth Reviews
1. INTEKIN Heavy Duty Bike Lock (8mm / 3 FT)
Our pick — over 4.5★ from 950+ verified ratings; the strongest balance of quality and price.
The ideal everyday lockdown that balances deterrent strength with a carry-friendly weight.
This is the motorcycle chain lock that gets the basics exactly right. The 8mm square links are cut from alloy steel and the lock core uses a precision-coded blade cylinder (the same kind you find in high-security door locks), not an easy-to-pick pin tumbler. That matters because it means the weak link is not the lock itself. The sliding dust cover over the keyhole keeps dirt and rain out, which owners say helps the lock stay smooth through all seasons.
At 2.87 lbs and 3 feet long, this is a lock you can actually carry without groaning. The fabric sleeve prevents scratches on your bike frame, and the crowd across 900+ reviews—who reward it a 4.7 average—praise its durability and sturdy feel. “Nice and heavy for the price” is a recurring sentiment. The honest trade-off is that an 8mm chain stops opportunists with bolt cutters but is not the ultimate choice against a determined thief with an angle grinder. That is the sacrifice for keeping the weight down.
What wins people over is the quality for the money. The reliability question is the one thing to check—a few owners mention the key can occasionally stick, so treat the lock gently and it should serve well. This is the pick for the daily commuter who wants solid security without carrying a boat anchor.
The Commuter Check
- Light enough to wrap on your frame or toss in a backpack at 2.87 lbs
- Fabric sleeve protects your bike paint from scratches
- 3-foot length is perfect for securing one wheel and the frame to a post
The Trade-Off
- 8mm chain is a strong deterrent but not the most extreme cut resistance available
- A small number of buyers report the key mechanism can need gentle handling
Best daily driver: Great for quick stops, office parking, and anyone who needs to carry the lock with them.
Think twice if: You park overnight in a very high-theft area and want the absolute thickest chain you can find.
2. NDakter Motorcycle Chain + U-Lock (10mm / 4 FT)
A versatile two-piece kit that lets you lock your wheel and frame separately.
The NDakter pair gives you a 10mm high-strength chain and a separate U-lock with an 18mm hardened steel shackle. That combo means you can loop the chain through your rear wheel and a post, then use the U-lock on the front wheel or through the frame. The 4-foot chain is made of 3T manganese steel, which owners confirm feels “very intimidating with the bar size” and acts as a strong visual deterrent. The nylon sleeve on the chain and the silicone protector on the U-lock keep everything scratch-free on your bike.
Compared to the lighter INTEKIN above, the NDakter weighs more in total but gives you the flexibility of two separate locking points. The U-lock itself is fairly compact—the internal space is 2.6 x 5.9 inches—so it fits most bike frames but may be tight around a thick motorcycle fork. Buyers give it high marks for quality and ease of use, calling it “very sturdy for the price.” The main recurring note is that the U-lock diameter feels small to some owners, so check your frame size before relying on it as your primary anchor.
Two-point lockdown: Use the chain for wide loops and the U-lock for tight frame security—flexible enough for an e-bike, scooter, or moped.
Fit check: The U-lock’s small internal space is the one thing to measure against your bike’s tubing before buying.
Reach for it if: You want the flexibility of a chain plus a U-lock in one package for different locking scenarios.
Look elsewhere if: You need to lock around very thick posts or your bike’s frame is unusually wide at the fork.
3. INTEKIN 10mm Chain + Disc Lock (3.1 FT)
A heavy, serious combination that feels like it could stop a truck.
This is the beefier sibling of the first INTEKIN pick, and the difference is all in the numbers. The chain jumps from 8mm to 10mm thickness, and the total weight climbs to 7.5 lbs—at 7.5 lbs versus the 2.87 lbs of the lighter model. The 10mm high manganese steel links are heat-treated and hardened, and the included disc lock adds a 16mm shackle with a PVC cover for corrosion resistance. Owners describe it as “insane” and “indestructible,” which is exactly the confidence you want when locking up a motorcycle overnight.
The 3.1-foot length is short enough to keep the weight manageable but long enough to wrap around a standard post and through your frame. “Great lock, I use it on my motorcycle on road trips” is a typical verdict. The honest caveat: a few owners mention the lock cylinder stopping working after a few months of heavy outdoor use, so keeping the dust cover closed and occasionally lubricating the keyway is smart maintenance. As one buyer summed it up, “the chain is great—pair it with a premium lock if you want the absolute best.”
Hard-hitting security: The 10mm chain and 16mm disc lock together create a pair that makes most thieves move on immediately.
Maintenance note: Treat the lock cylinder gently and keep it covered when not in use to avoid long-term sticking issues.
Perfect for: Road trips, overnight parking, and anyone who wants maximum cut resistance from a single kit.
Not your lock if: You need to carry it in a backpack daily—7.5 lbs gets old fast on a walk to the train.
4. WARLION Heavy Duty Security Chain (5 FT / No Lock)
A chain-only design built for people who already own a favorite padlock or U-lock.
The WARLION addresses that directly. It is a 5-foot, 3/8-inch thick hardened alloy steel chain that weighs 6.4 lbs, and it comes with a cinch ring (an O-ring design that lets you effectively extend the locking length by looping the chain back on itself). The zinc coating and detachable nylon sleeve resist rain and rust, and the chain integrates with padlocks, U-locks, or folding locks depending on your preference.
This is a heavier option than the INTEKIN 8mm chain above, but it gives you 5 feet of reach—enough to lasso a bike frame, rear e-hub wheel, and a hitch rack all at once. Owners praise its build quality, with one noting it “works amazing, great quality.” The cinch ring gets special mention for making it easy to wrap the chain tight around irregular objects. The catch is that you need to supply your own lock, which adds to the total cost and steps. If you already have a solid padlock, this is a very smart buy.
Mix-and-match security: Pair with your existing U-lock or padlock for a custom, high-strength combination.
Own lock required: No lock is included, so factor that into your total budget (and your daily carry weight).
Ideal if: You already have a trusted lock and just need a long, tough chain to complete your setup.
skip it if: You want one packaged kit with everything ready to go from the start.
5. REETOMETAL 6ft Security Chain (3/8 in / 7.7 lbs)
A 6-foot hardened steel chain that does double duty for two bikes or a bike and a trailer.
This is the longest chain in the mid-range tier, and that extra foot of reach compared to the WARLION makes a real difference. At 3/8 inch thick and made from triple heat-treated hardened steel, the REETOMETAL chain has a tensile strength (the force it resists before snapping) of 65 KN and a cutting resistance of 15 KN—numbers that translate to serious bolt-cutter resistance. The square-link design makes it harder for cutting tools to get a grip, and the protective nylon sleeve keeps your bike scratch-free.
Owners consistently call this a “badass chain” and recommend it for securing multiple e-bikes at once. The 6-foot length is enough to wrap around a thick parking sign and two bike frames. The downsides: at 7.7 lbs, it is heavy, and the cut resistance is rated as mixed by a small number of owners who question how long it would hold against an angle grinder. “This is a badass chain. Lock my ebike with it” sums up the bulk of the feedback. It is a strong choice for anyone who needs to lock more than one bike to a single anchor.
Multi-bike power: Long enough to secure two e-bikes to a single post, making it ideal for families or group rides.
Carry weight: The 7.7 lbs and 6-foot length are best suited for locking at a fixed location, not for daily backpack carry.
Best for: Home garage, shed, or workplace parking where the chain stays put and you need maximum reach.
Think twice if: You want a portable lock for quick trips where weight matters.
6. TEOOTD 10mm Chain Lock (5.3 FT / 8.6 lbs)
A long, heavy chain with a bright lock that screams “move along” to potential thieves.
The TEOOTD stands out visually—the U-lock is a bright copper color that is highly visible from a distance. That is not just aesthetics; a bright, obvious lock makes a thief think twice because they know they will be seen working on it. The chain itself is 10mm thick 3T manganese steel, and the U-lock has a very narrow 25mm inner diameter, which means a hydraulic shear tool cannot fit inside to pry it open. The chain resists 10KN of tension and 20KN of shear force, which is serious spec territory.
At 5.3 feet long and 8.6 lbs, this is a substantial piece of gear. Owners have used it for years on mopeds and to secure generators to containers, praising the heavy-duty build. “The bottom closes so weather conditions don’t mess up the lock—very heavy duty,” one buyer notes after years of use. The honest trade-off: some owners find the U-lock a bit tedious to thread onto the chain links and lock, and the sheer weight makes it a fixed-location lock rather than a portable one. The four keys are a nice backup feature.
See me, skip me: The bright copper lock is a visual deterrent that works alongside the physical strength of the chain.
Not for daily carrying: The 8.6 lbs and 5.3-foot length make this a “stay put” lock for a garage or a regular parking spot.
Great for: The rider who parks in the same spot every day and wants both heft and visibility as deterrents.
Not ideal for: Anyone who needs to toss their lock in a backpack for different locations.
7. OKG Hexagonal Cinch Chain (12mm / 3.3 FT / 9 lbs)
A 12mm hexagonal chain that packs extreme cut resistance into a relatively short length.
The OKG steps up to a 12mm hexagonal chain made from triple heat-treated boron manganese steel—that is a full 2mm thicker than most of the competition here and the same material grade used in the much more expensive Kryptonite New York chain. The hexagonal shape (six-sided links) makes it even harder for a bolt cutter to find a flat surface to grip. The included U-lock features a 16mm max-performance steel shackle with a double deadbolt mechanism and a stainless steel disc cylinder that resists drilling and picking.
Owners confirm the OKG is “sturdy” and “heavy duty,” with the noose-link (cinch ring) design making it easy to create a tight loop around a post and your bike frame. The nylon sleeve with a hook-and-loop fastener keeps the chain coiled neatly. At 9 lbs and 3.3 feet, this is a dense, heavy lock that is best used as a semi-permanent fixture rather than something you carry in a backpack. The honest consideration: some owners find the U-lock shackle too small for a trailer hitch, so measure your anchor point before buying. “The lock froze up after 3 years outdoors” is a rare but notable complaint about long-term weather exposure.
Maximum density: The 12mm hexagonal boron steel is as tough as chain locks get before you enter the premium tier.
Weather longevity: Keep the lock cylinder lubricated and covered if you park outdoors year-round to avoid freeze-ups.
Perfect for: The rider who prioritizes cut resistance over portability and parks at the same spot daily.
Check first: Measure the thickness of the post or hitch you will be locking to—the U-lock shackle is compact.
8. Kryptonite Evolution 1012 (10mm / 4 FT / 6.8 lbs)
The reliable mid-tier chain from the brand that practically invented the category.
Kryptonite is the name everyone knows in bike locks, and the Evolution 1012 lives up to that reputation with a solid, no-surprises design. The chain is 10mm hardened steel in a patented six-sided link shape, and the lock head uses a reinforced oval crossbar with a disc-style cylinder resistant to picking and drilling. The rubberized coating and weather-resistant nylon sleeve protect your bike frame. At 6.8 lbs and 47.25 inches of length, this is in the balance for e-bike owners who need a sturdy lock for daytime parking.
Owners call it “heavy, secure, and worth the haul,” noting that it works smoothly and opens every time. The unified design—where the chain is permanently attached to the lock head—means there is no separate padlock to fumble with. The Kryptonite Anti-Theft Protection Offer (ATPO) and KeySafe key replacement service add confidence. The straightforward trade-off is the weight at 6.8 lbs. “Maybe one of the better bike locks, but it weighs a lot” is a common note. It does not have the extreme cut resistance of the New York series below, but at this price point, it is the most refined all-rounder from a trusted brand.
Refined all-rounder: The permanently attached lock head makes setup fast and eliminates a separate padlock to lose.
Weight factor: At 6.8 lbs, it is heavy for daily backpack carry but manageable when wrapped on a bike frame.
Grab this if: You want the reassurance of a top-tier brand with a good balance of security, length, and weight.
Consider the New York if: You need maximum security and are willing to carry significantly more weight for it.
9. Kryptonite New York FAHGETTABOUDIT 1217 (12mm / 5.5 FT / 13.15 lbs)
The undisputed king of chain locks—massive, heavy, and designed to make thieves give up instantly.
This is the endgame. The New York FAHGETTABOUDIT 1217 is a 12mm chain made from maximum-strength 3T hardened manganese steel, with six-sided links for the ultimate cut resistance. The included Evolution Series 4 disc lock has a 14mm max-performance steel shackle and a hardened double deadbolt that resists pulling, drilling, and picking. Kryptonite rates this a 9 out of 10 on its own security scale, and the 5.5-foot length (170cm circumference) gives you enough reach to lock through both wheels, the frame, and around almost any fixed object. The sliding dust cover protects the cylinder from dirt and rain.
There is no sugar-coating the weight: at 13.15 lbs, this chain is a serious burden to carry. “HEAVY HEAVY HEAVY” is literally how one owner describes it. But for that weight, you get absolute confidence. The chain is long enough to wrap around a brake pedal and steering wheel of a car, and owners say it gives “zero worry about theft” even from expensive bike racks. “Serious lock for serious bikes” is the perfect summary. The practical downside is that it is not portable for daily biking—this is the lock you use when you park at a fixed location overnight or at a job site where theft risk is high.
Maximum security: The 12mm manganese steel and double deadbolt create a combination that forces a thief to use a loud angle grinder for several minutes.
The weight penalty: 13.15 lbs is not something you want in a backpack—this is a “stay-at-home-base” lock, not a commute companion.
Get this for: Overnight parking, high-crime areas, or securing a high-value bike to a fixed anchor at home or work.
Pick something lighter if: You need a lock you can carry with you every day on your bike or in a bag.
Understanding the Specs
Chain Thickness (mm)
This is the single most important spec for stopping a thief with bolt cutters. Every millimeter of extra thickness makes the chain exponentially harder to cut through. An 8mm chain is a solid deterrent for basic bolt cutters, a 10mm chain stops most handheld cutters, and a 12mm chain requires industrial power tools. The trade-off is weight: every extra millimeter adds noticeable heft that you will carry around.
Steel Type
Standard steel is easy to cut. Hardened steel is much tougher. Manganese steel—especially 3T (triple heat-treated) manganese steel—is the gold standard. It is the same material used in high-security prison locks and bank vaults. When you see “hardened manganese steel” in the specs, you know the chain has been heat-treated to resist drilling, sawing, and cutting. This matters much more than the chain’s color or coating.
Lock Cylinder Type
The cylinder is the engine of the lock. Disc-style cylinders (also called wafer cylinders) are much harder to pick than basic pin-tumbler cylinders. A good disc cylinder has anti-drill and anti-pull protection built in. A dust cover over the keyhole is essential for outdoor use—it keeps rain, dirt, and grime out of the mechanism so the lock does not seize up over time. Stainless steel keys last longer than brass or pot-metal ones.
Cinch Ring vs. Standard Chain
A cinch ring (also called a noose link or O-ring) is a loop built into the chain that lets you thread the other end through it, effectively creating a lasso. This lets you secure the chain tightly around an irregular object like a tree or a thick post without needing extra length. Standard chains require you to wrap the whole chain around the object and then lock the two ends together, which uses up more of the chain’s length. A cinch ring gives you more effective locking reach from the same nominal length.
