BIGLUFU Motorcycle Lock Chain Locks Heavy Duty 120cm - Cut Resistant

In this review of the BIGLUFU Motorcycle Lock Chain Locks, the bottom line is straightforward: this is a heavy, no-nonsense security chain best suited for riders or property owners who want visible, hard-to-cut protection. The lock stands out for its cut resistant 10mm square chain made from manganese steel and a stout 16mm U lock, so the single biggest reason to buy is the combination of a thick, square-linked chain and a reinforced U shackle that together prioritize theft resistance over lightness or compactness.

Key Features

• 3T manganese steel chain: The 10mm square-linked chain is engineered to resist cutting and can withstand high tension and shear forces for stronger security.
• Water-resistant sleeve: A nylon cover protects the chain and prevents scratches to paint or bodywork while resisting wear and exposure.
• Sturdy U lock: The 16mm zinc alloy shackle with PVC coating increases leverage and cutting resistance for added protection.
• Four ergonomic keys: Four stainless steel keys are included so multiple users or backups are available without worrying about bending or twisting keys.
• Generous length: At 120cm (4ft) the chain is long enough to secure a motorcycle to a post or link two bikes together for flexible locking options.

Who It's For

This chain lock is ideal for motorcycle and scooter owners who want a visible deterrent and a robust physical barrier against opportunistic thieves. It also suits users who need to secure larger items such as generators, gates, or multiple bikes because the 120cm length lets you loop through frames and anchors.

Riders seeking an ultra-light or minimalist lock for frequent carry may want to look elsewhere, since the emphasis here is on strength and cut resistance rather than low weight or compact storage. Also, those who need an electronic or alarmed lock feature will need a different solution.

Pros & Cons

Pros

• Thick 10mm square-linked chain offers strong resistance to cutters and leverage attacks.
• Durable nylon sleeve protects surfaces and helps the chain withstand weather exposure.
• Stout 16mm U lock and four stainless keys make daily use flexible and secure.

Cons

• Heavier and bulkier than lightweight locks, which can be awkward for riders who prefer minimal carry.
• Some users report mixed experiences with the lock mechanism, so care inserting the key fully is required to avoid jamming.

Our Verdict

Frequently Asked Questions

Can this lock secure two motorcycles?
Yes, the 120cm length is generally long enough to link and secure two motorcycles together depending on how they are arranged.

Is the chain protected against scratching paint?
The chain is wrapped in a water-resistant nylon sleeve designed to be scratch-proof and help protect paint and surfaces.

What should I do if the key feels stuck?
Insert the key fully before turning; the lock uses an anti-theft cylinder and incomplete insertion can cause the key to stick or the lock to fail to open.
