【Toughest Heavy-Duty Lock】

Upgraded thickened U lock shackle (21mm hardened alloy steel, 1.24kg/2.73lb) over thin lightweight generic locks. Resists bolt cutter cutting, prying and leverage damage. Inner dimension: 135mm × 145mm (5.31" × 5.71"). Note: Lock mounting bracket NOT included.

【Dual Double Bolt Lock Mechanism】

Dual-end locking design requires thieves to break both sides simultaneously, greatly boosting anti-theft performance. Effectively blocks pulling, jacking and forced prying attacks, far safer than single-bolt cheap locks.

【Full Silicone Protective Cover】

All-round thick silicone wrapping prevents scratches on bike frames. Waterproof & rustproof coating ensures stable performance in rainy weather, extending lock lifespan. Fits bicycles, e-bikes, scooters and motorcycles.

【3 Anti-Rust Laser Serpentine Keys】

Comes with 3 durable serpentine groove keys for spare backup, anti-corrosion for all weather. Tip: Fully push the lock bolt closed after locking to avoid key twisting damage.

【Spacious Inner Space & Lifetime Support】

Large inner space (5.31"W × 5.71"H) locks frames, wheels and poles flexibly. We provide lifetime after-sales warranty; contact us anytime for any product issues.
