E-Bike Commuters: If you've invested in an electric bike for daily commuting, this lock provides the level of security that matches your investment. The frame mount keeps the lock accessible and doesn't require you to carry extra weight in a bag, making it ideal for those who ride to work or school regularly and need quick, reliable protection at transit stops and parking areas.
Urban Cyclists: City riders who frequently lock their bikes in public spaces like cafés, shops, bike racks, need a visible deterrent that discourages opportunistic theft. This lock's substantial build and secure mounting system allow you to confidently leave your bike unattended during errands without constantly worrying about its safety.
High-Value Bike Owners: When your bicycle represents a significant financial investment, a basic cable lock simply won't do. This Sold Secure Gold-rated lock is designed for owners of premium road bikes, mountain bikes, and electric bikes who recognize that adequate protection is essential and worth the weight trade-off.
Multi-Bike Households: Families or couples with multiple bikes benefit from the ability to link two locks together for extended reach or to secure bikes to each other. The matching key system across multiple units simplifies logistics, so there’s no fumbling with different keys when you're trying to lock up and get moving.
Frequent Short-Stop Riders: If your riding style involves lots of quick stops, such as running into stores, picking up takeout, dropping off packages, you need a lock that deploys and stores easily without adding hassle. The folding design and frame-mounted case let you secure your bike in seconds and get back on the road without awkward carrying or storage.
Security-Conscious Cyclists: Riders who live in or frequently travel to higher-crime areas understand that visible, heavy-duty protection acts as both a physical barrier and a psychological deterrent. This lock's construction signals to potential thieves that your bike isn't an easy target, encouraging them to move on to less secure options.
Scooter Owners: Electric scooter users need portable security that doesn't compromise on strength. The folding format and included mounting system make this lock practical for scooters where space is limited, while the hardened steel construction provides peace of mind during brief stops or longer parking sessions.
Cable Lock Vulnerability: Standard cable locks can be cut through with basic bolt cutters in seconds, leaving your bike defenseless against casual thieves. This lock uses 0.25-inch hardened steel plates that resist bolt cutters and saws, requiring industrial tools and significant time to defeat, time most thieves don't want to spend in public view.
Inconvenient Lock Storage: Carrying a heavy chain in a backpack or U-lock on your frame can be awkward and uncomfortable during rides. The included frame-mountable case keeps this lock securely attached to your bike without rattling or shifting, so you always have it when you need it without the burden of manual carrying.
Limited Reach Frustration: U-locks often can't wrap around wider objects like thick poles, benches, or multiple bikes at once. With its 35.4-inch circumference when fully extended, this folding lock offers flexibility to secure your bike to various anchor points or even link two bikes together when needed.
Key Picking Concerns: Simple tumbler locks can be picked by experienced thieves relatively quickly and quietly. This lock uses an automotive-grade key system with a more complex mechanism that's significantly harder to pick, adding another layer of time and skill requirement that deters most would-be thieves.
Rivet Drilling Attacks: Many folding locks have exposed rivets that can be drilled out to separate the segments. This lock features patented anti-tamper rivets with reinforced guards against side attacks, making it extremely difficult to compromise the connection points without specialized equipment and considerable effort.
Weather Degradation: Locks that rust, freeze, or jam in harsh weather become unreliable exactly when you need them most. The waterproof and weatherproof construction with reinforced polymer coating protects the mechanism and materials from rain, snow, and temperature extremes, ensuring reliable operation year-round.
Noisy Transport Rattle: Carrying a lock that constantly clangs and rattles against your frame is annoying and can distract from your ride. The secure mounting bracket holds the folded lock firmly in place, eliminating noise and vibration even on rough roads or trails, keeping your ride peaceful.
Inadequate Visual Deterrent: Thin locks signal to thieves that a bike is poorly protected and worth targeting. This lock's substantial, professional appearance immediately communicates serious security, often causing thieves to simply move on to easier targets rather than risk the time and attention required to attempt a breach.
Key Loss Anxiety: Losing your only bike lock key can leave you stranded or force you to damage your own lock. This system includes three automotive-standard keys plus a key duplication card, giving you backups and the ability to easily create additional copies at a locksmith if needed.
Insufficient Insurance Coverage: Many bike insurance policies require Sold Secure Gold-rated locks for coverage to be valid. This lock meets that certification standard, ensuring your insurance claim won't be denied due to inadequate security measures if theft does occur.
Patented Rivet Protection: While many folding locks have vulnerable connection points, this lock features a patented anti-tamper rivet system with reinforced guards specifically designed to resist drilling and side attacks. The rounded, polished construction makes it nearly impossible to grip or compromise the joints without specialized industrial equipment.
Sold Secure Gold: This lock has achieved the 18/18 security rating and Sold Secure Gold certification, the highest independent security standard for bicycle locks. Most folding locks fall into lower categories, but this one has been independently tested to withstand professional attack methods for extended periods, meeting insurance requirements and providing verified protection.
Automotive-Grade Key System: Rather than using simple cylinder locks common in bike security, this lock employs an automotive-standard key mechanism that's significantly more resistant to picking. The higher-quality key system requires specialized skills to defeat, putting it beyond the capability of most bike thieves who rely on speed and basic tools.
Frame-Locking Mount System: The included mounting case doesn't just hold the lock. It actually locks the folded lock in place, preventing the lock itself from being stolen while mounted on your bike. This integrated security feature isn't standard on most folding locks, where the carrier is simply a holder with no locking mechanism.
Exceptional Plate Thickness: At 0.25 inches, the hardened steel plates are measurably thicker than most competing folding locks which typically use 5.5mm or thinner plates. This additional material thickness significantly increases resistance to cutting and grinding attacks, adding crucial minutes to any theft attempt.
Silent Carry System: The mounting bracket is specifically engineered to eliminate rattling during transport, even on rough terrain. While many frame-mounted locks create constant noise and vibration, this system keeps everything quiet and stable, preserving ride quality without compromising accessibility.
Dual Material Engineering: The combination of hardened steel core with Nylon 6 and glass fiber reinforced polymer coating provides both extreme cut resistance and protection against scratching your bike's finish. This dual-material approach balances security with surface protection better than bare metal or rubber-coated alternatives.
Three-Year Manufacturing Warranty: The included three-year warranty against product defects demonstrates manufacturer confidence in long-term durability. Most bike locks offer minimal or one-year coverage, but this extended protection period reflects the quality of materials and construction that allow reliable daily use over multiple years.
Daily Urban Commuting
An office worker rides their e-bike to work each morning, arriving at a busy downtown bike rack. They pull the lock from its frame mount in seconds, wrap it through the front wheel and frame around the rack, and lock it with a quick turn of the automotive key. The visible, heavy-duty appearance gives them confidence to focus on their workday rather than worry about their bike. At day's end, they unlock it just as quickly and fold it back into the mounted case for the ride home.
Quick Errand Stops
A parent needs to run into a grocery store for a few items while out on their afternoon bike ride. Rather than walking the bike through the store or leaving it completely unsecured, they use the folding lock to secure the bike to a pole near the entrance in under 30 seconds. The lock's substantial construction and Gold-level security rating provide peace of mind for short stops, knowing that casual opportunists will be deterred by the visible protection.
Weekend City Adventures
A couple takes their two e-bikes into the city for a day of exploring cafés and shops. At each stop, they link their two matching locks together, creating enough length to secure both bikes to a single post or bike rack. The matching keys mean either person can lock or unlock both bikes without fumbling through different keys, making transitions smooth and eliminating the frustration of coordinating security between two bikes.
Extended Outdoor Parking
An apartment dweller without indoor bike storage needs to secure their expensive electric bike overnight in a shared outdoor area. They wrap the lock through both wheels and the frame, then around a solid metal railing, taking advantage of the 35.4-inch reach to create a comprehensive security setup. The weatherproof construction means they don't worry about rain or temperature changes compromising the lock's function, and the three-year warranty provides long-term confidence in reliability.
Will this lock fit on the frame of my e-bike or scooter?
The mounting case is designed to attach to standard water bottle boss mounting holes found on most bike frames. The mounting holes use the same spacing as typical water bottle cages. If your bike or scooter doesn't have these mounting points, you can use the included mounting straps to secure the case to your frame, though this method may allow slight movement compared to the bolt-on installation.
How secure is this lock against angle grinders?
No lock is completely angle-grinder proof, as these power tools can eventually cut through any material. However, the 0.25-inch hardened steel plates require significantly more time and multiple cutting blades to penetrate compared to thinner locks, typically 1-4 minutes depending on the grinder and blade quality. This extended attack time, combined with the noise and sparks generated, makes this lock a strong deterrent in most real-world situations where thieves prefer quick, quiet theft.
Can I lock two bikes together with one lock?
Depending on frame size and thickness, you may be able to lock two bikes together with the 35.4-inch circumference, though this can be tight with larger frames or fat tire bikes. A better solution is purchasing two locks, which can be physically linked together to create extended reach. This also allows you to order matching keys across both locks for convenience, and you can separate them when locking bikes in different locations.
Is the lock weatherproof for year-round outdoor use?
Yes, the lock is designed to be waterproof and weatherproof with materials that resist rust, corrosion, and freezing. The hardened steel is protected by a Nylon 6 and glass fiber reinforced polymer coating, and the mechanism is sealed against moisture. Customers report reliable operation after years of outdoor storage and use in various weather conditions including rain, snow, and extreme temperatures.
What should I do if I lose all my keys?
The lock comes with three keys plus a key duplication card that contains the key code. If you lose all keys, you can take this card to a qualified locksmith who can cut new keys based on the code. We recommend storing the duplication card in a safe place separate from your keys, and consider having spare keys made and stored at home or work before you actually need them.
Does this lock work with insurance requirements?
Yes, this lock carries the Sold Secure Gold certification, which is the highest independent security rating for bicycle locks and is recognized by most insurance companies. Many bike insurance policies specifically require Sold Secure Gold-rated locks for coverage to be valid, so this lock meets that threshold. However, you should always verify your specific policy requirements with your insurance provider.
How heavy is the lock and will I notice it while riding?
The lock weighs 3.88 pounds, which is heavier than cable locks and U-locks but typical for high-security folding locks of this grade. When properly mounted in the included frame case, most riders report they don't notice the weight during normal riding, though some road cyclists sensitive to bike weight may prefer removing it for long recreational rides. The security trade-off is generally considered worthwhile for commuters and those with high-value bikes.
Will the lock rattle or make noise when mounted on my bike?
When properly installed and tightened, the mounting system is designed to hold the lock securely without rattling. Multiple customer reviews specifically praise the silent carry system. However, it's recommended to periodically check that the mounting case remains tight, especially after riding over rough terrain or potholes, as vibration over time can gradually loosen the mounting bolts.
Can bolt cutters cut through this lock?
Standard household or even professional-grade bolt cutters cannot cut through the 0.25-inch hardened steel plates. Only industrial bolt cutters (48+ inches, weighing 20+ pounds) would have a chance, and these are not tools that bike thieves typically carry due to their size and weight. The lock is specifically designed to resist bolt cutter attacks, which are the most common method used in bike theft.
What's covered under the 3-year warranty?
The warranty covers manufacturing defects in materials and workmanship for three years from purchase date. This includes issues with the locking mechanism, structural integrity of the steel plates, rivet construction, and key operation. Normal wear and tear, cosmetic scratches, damage from attempted theft, or misuse are not covered. If you experience a defect, contact the manufacturer with proof of purchase for warranty service.
Is 35.4 inches long enough to lock my bike to most objects?
The 35.4-inch circumference is sufficient for locking most bikes to standard bike racks, poles, and parking meters. It's long enough to secure the frame and one wheel to an object, though securing both wheels may require careful positioning. For larger frames, fat tire bikes, or situations where you need extended reach, consider purchasing two locks that can be linked together to effectively double your locking circumference.
How does this compare to a heavy chain lock in terms of security?
While the thickest chain locks may offer marginally better resistance to angle grinders, this folding lock provides comparable security to high-quality chains with significant practical advantages. It's more compact when folded, eliminates the noise and awkwardness of carrying a heavy chain, mounts cleanly to your bike frame, and offers more flexibility in wrapping around objects of varying sizes. For most urban and commuter applications, the security difference is negligible while the usability improvement is substantial.
