    Once a thief is riding your bike, no-one can tell it’s stolen. To passers-by they are just another cyclist. But not with the SR600. A 120dB siren in the face of the rider makes sure the thief and anyone nearby knows this bike is (trying to be) stolen! So if you were a thief what would you rather tackle: a dual layer lock + alarm or a single lock?


    Our patented alarm system has been developed specifically for cycling. By using a built in motion sensor the SR600 can recognise the difference between a real theft and an accidental bump or knock. You can rest assured that the SR600 will keep your bike safe, and you won’t get false triggers. 



    The SR600 torch has a built-in high capacity rechargeable battery bursting to 600 lumens, with 5 lighting modes delivering over 10 hours running time. Every torch has a unique serial number, meaning only a torch paired with the alarm can unlock it (see how to pair here).  The electronic connection between the torch and alarm make the SR600 completely safe from cyber attacks.


    If someone tries to steal your bike in person the SR600 can protect you. Pull the torch from the alarm and give your bike a small shake – the alarm trigger and wherever your bike goes the siren will follow it. Real time protection from your trusted companion.

    The alarm attaches to the front handlebar by a steel clamp. The jaws of the metal clamp create a formidable grip that ensures the SR600 will not come off in the event of a theft. 



    The alarm uses its own battery which is automatically recharged when the torch is connected. So once the alarm is set up you never need to think about it again. Arming, disarming and charging… all automatically done by the torch – easy!
