The LD-331 steel PVC keyed cable bicycle lock is designed for cyclists and vehicle owners who prefer the reliability and familiarity of a key-operated locking system. At the core of this lock is a braided steel cable that delivers excellent cut resistance, ensuring that bicycles, e-bikes, scooters, and motorcycles remain secure against theft. The steel cable is fully encased in a PVC/vinyl coating that protects the cable from rust and corrosion while preventing scratches to bicycle frames, motorcycle fairings, and other secured surfaces. Available in cable diameters of 8mm, 10mm, and 12mm, and lengths ranging from 600mm to 1200mm, the LD-331 provides the flexibility to handle everything from quick-stop errand locking to securing multiple bikes together at a rack or transit hub.

The key feature of the LD-331 is its 5-pin brass pin tumbler cylinder, housed within a durable zinc alloy lock head. Brass is the industry-standard material for lock cylinders because it offers superior wear resistance, corrosion resistance, and smooth key operation over thousands of locking cycles. Each lock comes with two precision-cut brass keys that provide reliable, consistent performance. The zinc alloy lock head is engineered to withstand impact, tampering, and harsh weather conditions, making the LD-331 suitable for outdoor use in any climate. Unlike combination locks, keyed locks eliminate the risk of forgetting a code, and the brass cylinder ensures that the key turns smoothly even after extended exposure to dust, moisture, and temperature fluctuations.

For wholesale buyers, cycling retailers, and promotional distributors, the LD-331 offers extensive customization options that make it a versatile product across diverse market segments. Custom cable lengths, diameters, PVC colors, key blank profiles, and logo printing on the lock head can all be specified to align with seasonal collections, corporate branding, or regional preferences. The lock is available in 8 color options including black, red, blue, green, pink, yellow, orange, and brown, appealing to a wide range of consumer tastes. Buyers can also choose between keyed-different systems, where each lock has a unique key, or keyed-alike systems, where multiple locks share the same key for fleet and multi-vehicle management. The minimum order quantity is 500 pieces, with mixed orders across sizes and colors fully supported and a production lead time of 15 to 25 days.

Each lock is individually packaged with a header card or blister pack featuring a plastic hook for retail-ready display, with 50 to 100 pieces per carton for efficient logistics. Comprehensive quality assurance is backed by CE, ISO 9001, and RoHS certifications, ensuring that every LD-331 lock meets international standards for safety, reliability, and environmental compliance. Whether you are a bicycle distributor seeking a dependable keyed cable lock, a motorcycle accessory retailer building a security product line, or an importer sourcing high-volume bike locks for promotional campaigns, the LD-331 keyed cable bicycle lock with brass cylinder delivers the security, durability, and customization flexibility that wholesale buyers demand.
