The safe alarm system for your bicycle
A lock is good; a lock with an alarm system is even better. With 100 decibels, the 440A padlock will send every thief running.
We protect our most valuable possessions with an alarm system. So why not our bike? Our padlock 440 Alarm is equipped with the proven 3D Position Detection System, which registers even the smallest movement. If a thief tampers with your bicycle, the lock sounds the alarm immediately. And at a volume that discourages: 100 decibels is as loud as a circular saw and can be heard from afar. An alarm like that will scare off any bike thief.
