DUAL-OPEN SECURITY & CONVENIENCE: Features a versatile hybrid lock head that supports both 5-digit combination (100,000 possible codes for high security) and key unlocking. Never worry about forgetting your password or losing your key; the dual-mode design ensures you always have access to your bike while providing robust anti-theft protection
HEAVY-DUTY ANTI-CUT MATERIALS: Constructed with a 6mm thick manganese steel chain and a 12mm thickened steel cable wrapped in durable PVC. The manganese steel offers excellent torsion resistance and anti-cutting performance, while the PVC coating protects your bike's paint from scratches and resists weather elements
VERSATILE HYBRID LOCK MODES: This 4-in-1 lock system allows you to switch between Combination Chain Lock, Keyed Chain Lock, Combination Cable Lock, and Keyed Cable Lock. Suitable for securing bicycles, motorcycles, electric bikes, scooters, gates, and fences. The flexible design adapts to various locking scenarios
EASY TO SET & USE: Setting your own custom 5-digit combination is simple and tool-free. Just align the dials, rotate the knob 90 degrees, set your desired code, and return to the initial position. The smooth-turning dials and ergonomic key slot ensure quick and hassle-free operation every time
PORTABLE & WEATHERPROOF DESIGN: With a total length of 95cm (3.12ft) for the chain and 115cm (3.77ft) for the cable, this lock is long enough to secure multiple bikes or large frames yet compact enough to carry in a backpack. The waterproof and rust-resistant materials make it suitable for outdoor use in all weather conditions
COMPACT LOCK HEAD DESIGN: Features a 1.3-inch diameter lock head that fits most bike wheel gaps and frame configurations. The reinforced zinc alloy construction provides extra defense against tampering and wear during daily use or long-term outdoor exposure
