conceived by german designer dennis siegel, the ‘RFID bikealarm’ is a motion sensitive electronic alarm system that is attached to the rails of a bike saddle. the device features omnidirectional movement sensors that detect tiny fluctuations an acceleration, emitting a 120db siren that scares away potential thieves. the internal micro controller is able to distinguish between theft and harmless vibrations, for instance a passing tram or regular pedestrian traffic. to mobilize the alarm system, the interaction is quite simple; users hold the unique radio-frequency identification tag close to the security enclosure to activate or dis-activate the ‘RFID bikealarm’.
the system complements mechanical bicycle locks by extending the range of protection with only a few components
the low-cost, durable and easy to use accessory features an internal battery that can be charged by USB
