The LD-329 hardened steel folding articulated bicycle lock combines the cut resistance of solid steel with the portability of a compact folding design. Built from hardened steel plates connected by riveted articulated joints, the lock extends to 600mm, 800mm, or 1000mm to wrap through a bicycle frame and wheel or around a fixed rack, then folds down to a compact 100-150mm length that mounts neatly on the bike frame. With 5 to 6 folding sections and steel plate thickness of 4 to 5mm, the LD-329 delivers a strong balance of security and everyday carry convenience for commuters, students, and recreational cyclists who need more protection than a cable lock without the bulk of a rigid U-lock.

Security is anchored by a zinc alloy lock cylinder featuring a 5-pin tumbler mechanism that resists picking and bumping, operated by nickel silver keys for smooth, corrosion-resistant performance. The hardened steel plates are specifically chosen to resist bolt-cutter and saw attacks, while the rubber or plastic coating applied to the plates protects the bicycle frame from scratches and paint damage during use. The articulated riveted joints allow the lock to flex around irregularly shaped objects and posts that a rigid lock cannot accommodate, and the coating is available in black with a red accent, solid black, red, or blue to suit personal style and brand identity. The lock fits tubes up to 30mm in diameter, covering most standard bicycle frames and common parking fixtures.

For wholesale buyers, cycling retailers, and promotional distributors, the LD-329 folding articulated lock is a premium, high-appeal product that performs well in both retail and OEM channels. Custom extended lengths, folding section counts, and coating colors can be specified to align with seasonal collections or corporate branding, and keyed-alike options simplify fleet management for bike-share operators and corporate cycling programs. The foldable design keeps logistics compact compared with chains of equivalent security, with efficient carton packing that reduces shipping cost per unit. Custom packaging options support retail-ready presentation, and OEM logo printing on the lock body reinforces brand visibility.

Backed by a minimum order quantity of 200 pieces and a production lead time of 20 to 30 days, the LD-329 offers importers a versatile, security-focused bicycle lock that meets the demands of urban commuters and recreational riders at competitive wholesale pricing. Mixed orders across lengths and colors are supported, giving distributors the flexibility to assemble balanced assortments from a single SKU family while maintaining consistent quality and lead times.
