The Best Bike Locks: 4 Compared (and One to Skip)
We compared a U-lock, a folding lock, a wearable chain, and a lightweight band on security rating, weight, portability, and mounting.
The verdict in 30 seconds
What mattered most
- Lock type
- Independent security rating
- Approx. weight
- Portability / carry
- Mounting
- Locking flexibility
Bike locks force a trade-off between security and how much weight you are willing to carry, and no single design wins on both. We lined up four proven 2026 models spanning the main categories: a hardened U-lock, a folding lock, a wearable chain, and an ultralight band. Two earn a clear buy, one depends entirely on your bike and route, and one should stay reserved for the lowest-risk stops.
A 16mm hardened U-lock that shrugs off hand tools and remains the default choice for high-risk city parking.
Best for: Commuters parking in dense urban areas who want maximum hand-tool resistance in a compact form.
- Carries a top-tier independent security rating and a double-deadbolt shackle that resists bolt cutters and leverage attacks
- 16mm hardened steel intimidates opportunists before a tool is drawn
- Includes a frame-mount bracket and covered disc-style keyway with anti-theft protection registration
- Heavy for its compact locking area, at roughly four pounds
- Like nearly all consumer locks, it yields to a determined angle-grinder attack
The rare folding lock with genuine high-security credentials, folding flat to a pocketable block while wrapping awkward objects a U-lock cannot.
Best for: Riders who prize flexible locking geometry and easy carry but refuse to drop to cable-lock security.
- One of the very few folding locks to earn a top independent security rating, with 5.5mm hardened steel bars and a pick-resistant disc cylinder
- Folds into a compact block and reaches around fat posts, racks, and large frames that defeat a rigid U-lock
- Ships with a solid frame-mount holster for rattle-free carry
- Heavy for a folding lock and priced at the top of the category
- The many rivet joints are inherently more attack points than a single U-lock shackle
A Gold-rated 10mm chain you wear around your waist, trading serious heft for the freedom to leave the bike unmounted.
Best for: Owners of big or heavy bikes who would rather wear the lock than mount it, and who accept the weight.
- Carries a strong independent security rating from 10mm hardened chain links and a 12mm shackle padlock
- Patented belt clasp lets you wear the chain while riding instead of bolting a bracket to the frame
- Long locking span suits large frames, cargo bikes, and e-bikes
- Very heavy, at over five pounds, which owners feel on longer rides
- Owners report the mechanism is fiddly and slow to engage, needing precise key alignment
A featherweight banded lock that coils into a jersey pocket, but hand snips defeat it in seconds, so it is a deterrent, not real security.
Best for: Cyclists and cafe-stop riders who need a lightweight deterrent for brief, low-risk, in-sight stops.
- Extraordinarily light and packable, coiling to roughly a three-inch diameter
- Multiple stainless steel bands resist casual cutting and quick grab-and-go theft
- Combination dial means no keys to lose
- Independent testing and owner reports show it can be severed by hand tools such as tin snips in seconds
- The maker itself positions it only as a supplement to a real lock, not a standalone one

How we judged the field
We do not run our own destructive lab. Instead we synthesize independent security testing, established third-party rating schemes, and aggregated owner reports, then weigh them against how a lock actually fits into daily riding. Four things mattered most:
- Security rating: independent, published resistance to hand tools and picking, not marketing numbers alone.
- Weight and carry: the honest daily cost of protection, since a lock left at home protects nothing.
- Portability and mounting: whether the lock rides cleanly on the frame, on your body, or in a bag.
- Locking flexibility: how easily the lock reaches a solid anchor around real frames and wheels.
One truth frames everything below: reviewers and independent testing agree that no lock in this class survives a cordless angle grinder. The realistic job is to resist hand tools long enough that a thief moves on, so we judged these locks as deterrents matched to a risk level, not as guarantees.
Kryptonite New York Standard Heavy Duty U-Lock — buy
This is the lock that defined serious city security, and it still earns its place. Its 16mm hardened shackle and double-deadbolt design mean a thief must defeat two locking points, and independent testing reports it as effectively immune to hand tools, cordless drills, and leverage attacks. It carries a top-tier independent rating, ships with a frame bracket and a covered keyway, and backs itself with an anti-theft registration program. The honest cons are weight, roughly four pounds for a fairly small locking window, and the same angle-grinder vulnerability every lock here shares. For riders in high-theft areas who want the most proven hand-tool resistance per dollar, it is the safe default.
Abus Bordo Granit XPlus 6500 Folding Lock — it depends… buy
Folding locks usually trade away security for convenience; this one mostly refuses to. It is among the very few folding locks to earn a top independent rating, built from 5.5mm hardened steel bars riveted together and secured by a pick-resistant disc cylinder. Folded, it collapses into a compact block that drops into a frame holster; unfolded, it wraps around thick posts, racks, and large frames that a rigid U-lock cannot reach. The trade-offs are real: it is heavy for a folding lock and sits at the top of the category on price, and its many joints are inherently more attack points than a single shackle. For riders who value flexible locking geometry and easy carry without dropping to cable-lock security, it is a genuine buy.
Hiplok Gold Wearable Chain Lock — it depends
The Hiplok Gold solves a specific problem elegantly: how to carry a real chain without bolting hardware to your frame. Its 10mm hardened links and 12mm shackle padlock earn a strong independent rating, and a patented belt clasp lets you wear the chain around your waist while riding. The long span suits big frames, cargo bikes, and e-bikes that defeat compact locks. But it is very heavy, over five pounds, which owners feel on longer rides, and owner reports consistently describe the mechanism as fiddly and slow, needing precise key alignment to engage. Whether it is right for you depends almost entirely on your bike and tolerance for weight, which is why it lands at “depends” rather than a blanket buy.
Ottolock Hexband Cinch Lock — skip
The Hexband is a delight to carry and a liability to trust. It weighs only a few ounces, coils to roughly a three-inch disc, and uses layered stainless steel bands plus a combination dial, which is enough to deter a casual grab-and-go. The problem is decisive: independent testing and owner reports show it can be severed with hand snips in seconds, and the maker itself positions it only as a supplement to a real lock. As the sole security for anything you value, it should be skipped. It has a narrow, legitimate role as a lightweight deterrent for brief, in-sight stops, but that is a supporting part, not a lead.
Kryptonite New York Standard vs Abus Bordo 6500: which should you buy?
Both carry top independent security ratings and weigh about the same, so the decision is about shape and use, not raw strength. The Kryptonite is a rigid U-lock: fewer attack points, the most reassuring single-shackle security, and a compact profile, at the cost of a small locking window that can be awkward around fat frames. The Abus folds flat and unfolds long, so it reaches anchors and frame shapes the Kryptonite simply cannot, and many riders find the folded block easier to stash. Choose the Kryptonite if you lock to standard racks in a high-theft city and want the simplest, hardest target. Choose the Abus if your parking spots are varied or your frame is large, and you will pay a little more for the flexibility.
What to look for
- A published independent security rating, not just a brand’s own scale, and ideally a gold or diamond equivalent for city use.
- Weight you will actually carry every day; the strongest lock is worthless if it stays home.
- A locking span that fits your bike and anchor, especially for fat frames, wheels, and e-bikes.
- A carry method that suits you, whether a frame bracket, a folding holster, or a wearable belt.
- Realistic expectations: assume any lock can be angle-ground, and prioritize busy, lit, well-anchored parking.
Our final take
Security and convenience pull in opposite directions, and these four locks map that tension cleanly. The Kryptonite New York Standard is the default answer for most city riders: top-tier hand-tool resistance in a compact, well-mounted package. The Abus Bordo 6500 is the smarter buy when locking geometry or carry matters more than a single-shackle design, and it is the rare folding lock that keeps the security. The Hiplok Gold rewards owners of big or heavy bikes who would rather wear their lock than mount it, provided they accept real weight. The Ottolock Hexband is best understood as a pocketable deterrent, never the only thing between a thief and your bike. Pick the lock that matches your risk, then park like the grinder is always a possibility.
Questions, answered
Which bike lock type is most secure: U-lock, folding, or chain?
A hardened U-lock generally gives the most security for its weight because a single thick shackle offers fewer attack points than the joints of a folding lock or the links of a chain. High-end folding and chain locks like the Abus Bordo 6500 and Hiplok Gold can reach comparable independent ratings, but they do so by adding weight. The lightweight band category, such as the Ottolock Hexband, sits well below all of them and should be treated as a deterrent only.
Can any of these locks stop an angle grinder?
No. None of the four locks here is designed to defeat a cordless angle grinder, and independent testing shows determined thieves can cut through standard hardened steel with one. Angle-grinder-specific locks exist and are heavier and more expensive. For these models, the realistic goal is to resist hand tools long enough to deter theft, so combine a strong lock with well-lit, busy, camera-covered parking.
How much lock weight do I actually need?
Match the weight to your risk, not the maximum available. For high-theft cities, the roughly four-pound Kryptonite or Abus is a reasonable carry for the protection gained. For low-risk short stops where you keep the bike in sight, the sub-half-pound Ottolock is far more pleasant to carry, accepting that it is only a deterrent. The five-pound-plus Hiplok Gold makes most sense when it is worn rather than mounted.
What is the best lock for an e-bike or a large-framed bike?
Larger frames and e-bikes need a long enough locking span to reach a solid anchor around a thick frame and wheel. The Hiplok Gold's long chain and the Abus Bordo's reach handle this better than a compact U-lock, whose small window can be hard to fit around fat tubes. Because e-bikes are high-value targets, favor a high independent security rating and, where practical, use two different lock types together.
Do these locks come with a mounting bracket?
The Kryptonite New York Standard and the Abus Bordo 6500 both include a frame mount, a bracket and a folding-lock holster respectively, for rattle-free transport. The Hiplok Gold has no frame mount by design; it is worn around the waist using its belt clasp. The Ottolock has no mount and simply coils into a pocket, bag, or saddlebag.
