Immediate theft deterrence, with a 110 dB vibration-triggered alarm
A sensitive motion sensor detects vibration or movement, arming after a three-second delay following the push-on lock and sounding at 110 dB when triggered. The alarm is designed as an audible alert rather than a tracking or immobilisation system.
High-volume alarm interrupts theft attempts and draws attention quickly, useful when leaving a bike on the street, in communal parking or at events.
Reliable locking action, with an aluminium alloy cylinder and copper key
A self-developed aluminium alloy cylinder works with a smooth copper key for positive engagement, and the lock body is sealed to resist ingress from rain and impacts. The design aims to reduce binding and key jamming under frequent use.
Smoother key action means fewer sticking incidents and a more dependable daily routine for riders who lock and unlock frequently.
Practical rider reminders, with a reminder cable and spare batteries included
A reminder rope attaches between the lock and handlebar to warn before setting off, while an extra set of batteries is supplied for quick replacement. The unit signals low battery with a repeated "Ge Ge Ge" sound.
Reminder cable reduces the chance of riding away with the lock fitted, and included spare batteries help maintain protection without immediate trips to a shop.
