Sportneer Bike Lock: 5 Digit Combination High Security Anti Theft Bike Chain Lock - 3.2/3.6/4ft Heavy Duty Keyless Bicycle Lock for Bike, Motorcycle, Scooter, Door & Gate - 4/6mm Thick, Easy to Use
At $11.39, the Sportneer 5-Digit Combination Bike Chain Lock provides accessible secondary deterrence using 6mm manganese steel links and a keyless zinc alloy tumbler. While practical for daytime errands and low-risk environments, its lighter link profile is not engineered to safeguard high-value bicycles or e-bikes left unattended for prolonged periods.

Best for Low-risk secondary locking and quick errand stops
At roughly eleven dollars, this chain lock functions purely as a low-level opportunistic deterrent. The thin chain links offer negligible resistance against manual bolt cutters and pry attacks. It should never serve as primary security for an e-bike or valuable commuter.
What we like
+Keyless resettable five-digit combination
+Sleeve covers chain to prevent paint scuffs
+Extremely low financial investment
What to weigh up
−Thin links yield quickly to cutting tools
−Combination dials can jam in wet, grimy conditions

The full review
Design and Build Quality
The Sportneer chain lock is constructed around 0.236-inch (6mm) manganese steel links paired with a zinc alloy locking core. Manganese steel provides basic tensile resistance against manual sawing and light shearing, while the zinc alloy core houses a five-digit resettable combination mechanism that yields 100,000 possible codes. To safeguard frame paint from direct metal contact, Sportneer wraps the chain in a continuous polypropylene fabric sleeve, which also shields hands during cold or wet weather handling. A plastic dust cover is integrated to block road grit and water ingress into the tumbler assembly. However, buyers should note the lock head carries a substantial 1.3-inch outer diameter. This thickness demands sufficient clearance between wheel spokes and frame stays if the head must pass through narrow apertures. The construction is functional and straightforward, though the lack of an independent security testing certification from bodies like Sold Secure reflects its positioning as a utility-grade rather than high-security barrier.
Real-World Performance and Usability
Operationally, the keyless interface functions reliably for daily utility stops. Eliminating physical keys removes the risk of lost hardware, and setting the code involves a standard 90-degree internal dial rotation from the factory default of 00000. The five separate number wheels rotate with distinct indexing, though the plastic construction of the dials requires deliberate alignment to engage cleanly. At lengths ranging from 3.2 to 4 feet depending on the purchased variant, the chain provides enough reach to capture a standard frame and rear wheel against an anchored signpost or bike rack. However, threading the 1.3-inch locking head through tight spoke patterns on compact wheels or disc brake rotors can prove difficult. When clearances are too narrow, the chain must be routed entirely around frame tubes rather than through wheel rims. The textile sleeve effectively mitigates paint scratching during transit, but it can absorb road grime and moisture in heavy rain, requiring periodic drying.
Value for Money
Listed at $11.39, the Sportneer lock represents a very low financial barrier to entry, supported by an aggregate score of 4.5 stars across more than 12,800 consumer reviews. At this price, the inclusion of a 6mm manganese steel chain, an integrated resettable combination barrel, and a full-length protective sleeve offers unquestionable utility per dollar spent. Premium locks featuring 10mm hardened steel links, disc-detainer key cylinders, and independent theft guarantees command prices four to eight times higher. The trade-off here is strictly security grading: you are purchasing basic physical deterrence and opportunistic theft prevention rather than verified attack resistance. For secondary duties—such as securing a front wheel to an already anchored frame, tethering a helmet, or locking a low-cost commuter outside a busy coffee shop for five minutes—the return on investment is sound. Buyers seeking guaranteed loss protection or manufacturer-backed insurance schemes will not find them at this price tier.
Who Should Skip It
Riders locking premium electric bicycles, high-end road machines, or cargo rigs should pass on this product as their primary defense. Modern e-bikes represent considerable financial investments, and a 6mm chain profile can be breached in seconds by medium-to-large manual bolt cutters or portable battery-powered angle grinders. If you routinely leave a bicycle unattended for extended hours on university campuses, urban transit stations, or overnight city streets, this chain will not provide adequate physical resistance. Furthermore, owners of bikes with densely laced wheels, deep aero rims, or tight disc caliper clearances may find the bulky 1.3-inch locking head impossible to route through critical components. Commuters operating in high-theft corridors should invest in a heavy-gauge Sold Secure Gold or Diamond rated U-lock or a hardened 10mm-plus chain instead, retaining lightweight combination cables and 6mm chains strictly for ancillary gear securing.

What the maker claims
—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 possible combinations, making it virtually impossible to crack. This bike chain lock is the perfect choice for those who value safety and convenience above all else.
—Rock-solid & Built to Last : The Sportneer bicycle lock is as tough as nails. Crafted from ultra-thick 0.236"/6mm manganese steel, it boasts unparalleled resistance against cutting and sawing. The lock core, made from sturdy zinc alloy, adds an extra layer of protection, thwarting any attempts at malicious cutting and ensuring long-lasting durability.
—Scratch-Resistant Cover & Dustproof Cap: The flexible high-quality polypropylene fabric cover protects your hands against heat or cold, and prevents chain from rust, and keeps the bike paint from scratches, ensuring the lock lasts for years to come. Plus, the dustproof cap is an added bonus, keeping rainwater and sand out of the lock hole.
—Convenient & Easy to Reset: Setting up and resetting your personalized combination password is a breeze. The initial password is 00000, and when it's time to set a new password, simply keep the number wheels in the correct unlock password state and rotate the reset dial 90° to set the new password. No more worry about forgetting your password or struggling to reset it again.
—Versatile Applications: With options available in lengths of 3.2ft, you can easily lock two bikes together. Better yet, this bike lock is also suitable for a wide range of applications, including bicycles, electric bikes, ladders, lawnmowers, gates, fences, toolboxes, sports equipment, and more.
—Note: The bicycle lock head diameter is 1.3 inches. Before making a purchase, ensure that the gap between the tires or the hole you need to pass through is compatible. Otherwise, you can still lock your bike by wrapping the chain around it, rather than threading it through the wheel's gap.

Sportneer Bike Lock: 5 Digit Combination High Security Anti (this one)
A dash means the value was not recorded, not that a feature is absent. Prices and ratings are captured snapshots; editorial scores are research assessments rather than measured performance.
Common questions
Can this lock resist bolt cutters or angle grinders?
No. While the 6mm manganese steel links withstand basic hand saws and small manual cutters, they lack the mass to resist medium or large bolt cutters. Additionally, no standard 6mm chain will survive a cordless angle grinder attack, which cuts through this gauge in a matter of seconds.
How do you reset the 5-digit combination?
To reset the combination, first align the dials to the default code of 00000 and unlock the chain. Rotate the built-in reset knob 90 degrees clockwise, dial in your chosen five-digit sequence, and rotate the reset knob back to its starting position to lock in the new code.
Will the 1.3-inch locking head fit through all bicycle wheels?
Not always. Wheels with closely spaced spokes, small diameters, or integrated hub hardware often have openings smaller than 1.3 inches. If the lock head cannot slide between spokes, you must secure the bicycle by wrapping the chain around the frame tubes and external anchor points instead.
Is this lock sufficient for securing a high-value e-bike?
This lock is insufficient as primary security for high-value electric bikes. E-bikes present high-value targets for thieves equipped with serious leverage or cutting tools. A 6mm chain functions best as a secondary deterrent for wheels or accessories, while a certified heavy U-lock should anchor the main frame.
How we judge e-bikes & cycling accessories
Rule 01
Torque, not top speed, is what you feel on a loaded hill start.
Rule 02
Verify exact-model UL 2849 certification for the e-bike electrical system; UL 2271 applies to battery packs. A listed component alone does not certify the whole bike.
Rule 03
Check brake type, rotor size and maintenance requirements against total load, terrain and intended speed; bike weight alone does not establish stopping performance.
