Stops theft quickly – with a 113dB super loud siren
A 113dB siren produces a piercing audible alert, while seven adjustable sensitivity levels allow the trigger threshold to be matched to vibration or movement. Sensitivity can be set to avoid false alarms from light knocks or to react strongly to aggressive tampering.
Immediate attention from passers-by reduces the chance of theft, and sensitivity settings let owners adapt responses for busy streets or quiet storage.
Built for outdoor use – with IP55 PC shell waterproofing
IP55 rating provides protection against dust and water jets, and the PC plastic casing shields internal electronics from exposure. The waterproof design supports routine outdoor mounting on frames or stems.
Suitable for regular outdoor use on bikes and scooters, surviving light rain and typical weather without needing frequent removal.
Quick to fit and control – with remote and two mounting options
A handheld remote enables arming, disarming and a one-key find function from up to 20 metres, while the unit mounts either with double-sided sticker or with ties. Extra remotes are available separately for family members.
Fit the alarm in minutes without tools, give a spare remote to a partner, and use the find-vehicle feature to locate a parked bike in crowded areas.
