Kewig Motorcycle Helmet Lock Aluminium — Anti-Theft 3-Digit Combo with 500mm Cable

This compact lock is built from 6063 aluminum alloy with a hard-anodized finish to resist oxidation and corrosion while remaining lightweight. A zinc-alloy combination cylinder (default code 000) provides keyless convenience and double anti-theft protection, and the included PVC-coated 5mm steel cable adds reach and abrasion resistance without scratching helmets or paint.

How does this lock attach to different bikes and bars?

The Kewig helmet lock accommodates a wide range of round tubing thanks to removable TPU rubber ring inserts. Use the 22mm or 25mm insert for narrower bars, or remove inserts to fit up to 28.6mm (1.125") diameter tubing, making it compatible with motorcycles, scooters, bicycles, ATVs, and roll cages.

• Supports 0.87" (22mm), 1" (25mm), and 1.125" (28.6mm) bar diameters.
• Simple clamp mounting with included Allen wrench for secure fitting.
• Works on tubular handlebars, roll cages, and any round rail.

How secure is the combination cylinder and body against tampering?

The 3-digit combination cylinder is zinc alloy with an electroplated finish and is designed for straightforward code setup and use. The aluminum alloy body is CNC-machined and paired with a double anti-theft design to increase resistance to common attack methods.

• Default code set to "000" and fully customizable to your own number.
• Double anti-theft engineering resists cutting, drilling, prying, and bending attempts.
• Hard anodized surface improves corrosion resistance in harsh environments.

What does the cable add, and how durable is it?

The supplied 500mm steel cable combines multiple high-tensile steel strands with a PVC coating to prevent scratches and extend reach when locking a helmet to a frame. At 5mm diameter it balances flexibility with tensile strength for everyday security and abrasion resistance.

• 5mm diameter high-toughness steel core for load-bearing capacity.
• PVC-coating protects helmet finishes and vehicle paintwork.
• 500mm length gives enough slack for straps, seat loops, or quick attachment points.

Who is this for? Riders who want a slim, versatile helmet locking solution for motorcycles, e-bikes, scooters, and bicycles will find the Kewig Aluminum Alloy Anti-Theft Helmet Lock a practical choice. It’s aimed at daily commuters and recreational riders who prefer a keyless combination, corrosion-resistant materials for outdoor use, and an included cable for flexible attachment. The package includes the lock, two TPU rubber ring inserts (22mm and 25mm), an Allen wrench, the 5mm steel cable, and a concise instruction manual for quick setup.
