MARQUE Bike Lock With Key
The MARQUE Lock with Key is a 3/8″ (approximately 9.5 mm) cable lock offered in multiple lengths, including 4, 7, 15, and 25 feet. It uses vinyl coating to prevent scratching on bikes and other secured items. The design emphasizes versatility: the cable’s male end fits through narrow spaces, making it practical for securing kayaks, paddle boards, scooters, gates, and similar items. The lock comes with two keys for replacement convenience, ensuring quick access when needed.
MARQUE Combination Bike Lock Cable
The MARQUE combination lock uses a 3/8″ cable with multiple length options (5, 10, 15, and 25 feet) and a resettable code. Its vinyl-coated cable helps prevent surface scratching on secured items. Designed for multi-use security, the lock’s flexible design supports securing bicycles, kayaks, paddle boards, gates, and other equipment. The absence of keys adds convenience for those who prefer a code-based system with quick recall.
Master Lock Cable Lock
The Master Lock Cable Lock features a 6-foot braided steel cable with a combination mechanism. Its four-digit code offers quick access without needing a key. The lock is designed for general outdoor use and can secure bikes and other outdoor gear. A protective vinyl coating helps guard against scratches, while the braided steel provides flexibility for routing the lock around irregular shapes and anchoring points.
NDakte Bike Lock
NDakte offers an extra-long straight cable lock ranging from 6 to 27 feet with a resettable combination. The male end is designed to be unique and narrow, aiding access through tighter gaps. The 8 mm cable diameter is paired with a vinyl coating for weather resistance and to minimize scratching. This lock is pitched for a variety of outdoor uses, including bicycles, scooters, gates, and boards, with the added capability to secure multiple bikes in one position when needed.
Kryptonite Keeper 712 Bike Chain Lock
The Kryptonite Keeper 712 is a four-sided-link, 7 mm hardened steel chain lock designed for high resistance to cutting and leverage attempts. It uses a patented locking system with a disc-style cylinder that resists picking and drilling. The chain is protected by a durable rubber coating and an outer weather-resistant nylon sleeve to prevent scratching and weather wear, making it suitable for bikes, motorcycles, scooters, and more when security is a priority.
Buying Guide: Key Considerations For Long Bike Chain Locks
Choosing the right long bike chain lock involves balancing length, material strength, and ease of use. Here are important factors and how they impact security and practicality.
- Lock type and security level: Keyed locks offer quick access with spare keys, while combination locks forego keys but require memorizing a code. For urban environments with frequent lock/unlock cycles, consider a high-visibility, vibration-resistant mechanism.
- Material and construction: Hardened steel chains with protective sleeves reduce scratching and resist cutting attempts. Cable locks are more flexible and easier to thread through tight spaces but may offer lower cut resistance than chain locks.
- Diameter and length: A longer length increases anchoring options but can reduce stiffness. For most everyday security needs, 3/8″ (about 9–10 mm) to 7 mm chains are common, with longer lengths offering more mounting flexibility for bikes, gates, and equipment.
- Surface protection: Vinyl or plastic coatings prevent surface scratches on bikes and accessories. Ensure coatings cover high-contact areas to extend the life of secured gear.
- Weather resistance: PVC coatings and protective sleeves guard against rain, humidity, and salt exposure, preserving lock function and preventing rust or corrosion.
- Ease of use: Resettable combinations reduce key management, but tracking codes across multiple locks can be challenging. Keys are simpler for some users who prefer quick, predictable access.
- Maintenance: Regularly clean locks exposed to saltwater or humid environments. Lubrication can extend life and prevent sticking in combination or keyed mechanisms.
- Versatility: If you secure multiple items (bikes, kayaks, gates), prioritize locks with longer lengths and narrow ends suitable for spaces through which you must thread the cable.
Overall, long bike chain locks are best evaluated by intended use-case, environment, and the balance between convenience and tamper resistance. For high-theft areas or securing valuable equipment, a heavier chain with a robust locking mechanism paired with a secondary, secondary deterrent (and secure anchoring points) may provide enhanced protection.
