| I expect i will get shot down for this, i dont believe in alarms if your honest with your self how often have you heard an alarm going off and actualy gone and looked to see if some piky was stealing a bike/car/breaking into a house ? A bike can be thrown in a van and off in less time than it takes to read this.
A good chain around a solid object or another bike when your out and about in town is a far better deterent, and when at home locked in the garage with added ground anchor etc.
i use bike-trac if the bike gets moved i get a text so do others on my list, you can see the bikes location on line so a good chance of getting it back.
Just my preference i expect others have different views. |
