LD-314 Alloy Steel PVC Chain Lock Bicycle Motorcycle Security | Wholesale Supplier

The LD-314 alloy steel PVC chain lock is engineered to deliver reliable anti-theft protection for bicycles, motorcycles, electric bikes, and scooters in everyday urban and suburban parking environments. The chain is forged from hardened alloy steel links heat-treated to a high hardness level that resists bolt cutters, hacksaws, and leverage attacks far more effectively than standard mild steel chains or braided cable locks. With link diameters available from 6mm up to 10mm and chain lengths ranging from 0.6m to 1.2m, this lock accommodates everything from lightweight commuter bicycles to heavier motorcycles that require securing around thick posts, railings, and parking racks. The hardened steel core provides the true cut resistance that deters opportunistic theft, forcing would-be attackers to resort to noisy power tools that draw attention in public spaces.

A seamless PVC or nylon protective sleeve fully encases the chain, preventing direct metal-to-metal contact that could scratch bicycle frames, motorcycle paint, and powder-coated finishes. The sleeve is offered in blue, black, green, and red, allowing brand color matching and easy fleet identification for rental and sharing operators. The integrated keyed lock head houses a precision brass cylinder paired with nickel silver keys, delivering smooth operation and dependable corrosion resistance through years of outdoor exposure. The lock head is ergonomically shaped for comfortable handling, and the keyed mechanism supports keyed-different, keyed-alike, and master key configurations to simplify management for households with multiple bikes or commercial fleets with dozens of vehicles. Each lock ships with two to three nickel silver keys for convenient backup access.

For wholesale buyers, importers, and distributors, the LD-314 offers extensive OEM and ODM flexibility. Custom logos can be embossed on the lock head and printed on the PVC sleeve, while chain diameter, length, and color can be tailored to specific market requirements. The lock meets CE and ISO 9001 quality standards and is supplied in individual PE bags or color boxes with foam-divided cartons for safe international shipping. With a minimum order quantity of 200 pieces and a production lead time of 15 to 25 days, this chain lock is an ideal addition to any security hardware catalog targeting cycling, motorcycle, and outdoor recreation retail channels.
