Portable Everyday Security – with armoured Steel-O-Flex construction

A flexible steel cable is wrapped in hardened steel sleeves to create a double layer of protection while maintaining pliability. The Steel-O-Flex design resists common cutting attempts better than an unarmoured cable.

Easy to coil and carry while still offering a credible deterrent for short stops. Perfect for quick errands, school runs or commuter parking where heavy-duty locks are impractical.

Versatile Locking Options – thanks to an 85 cm, 15 mm cable

The cable length of 85 cm and 15 mm thickness allow it to loop around frames and fixed objects without excessive bulk. The dimensions balance reach with manageable weight for daily use.

Allows locking to a variety of stands and rails without stretching, making it suitable for mixed urban and suburban routes. Compact enough to store on a rack or in a small bag when not in use.

Simple Access Control – with a 4-digit adjustable code and dark key function

A 4-digit numerical code can be individually set, and a dark key function simplifies operation in low light. Packaging also includes two keys, giving an alternative access method.

Quick to unlock for the rider while avoiding the need to carry a single vulnerable key. The combination option is handy for shared use between family members or short-term lending.
