Bike alarm scares away thieves

Motion detecting bike alarm sounds off when bike lock gives way

Bike thieves suck, and German designer Dennis Siegel has created a way to stop them in the act when they’re jacking your ride.

Referred to as the RFID Bikealarm (catchy, I know), this tiny little sensor gets attached to the bike seat and sounds off when the bike lock gives way.

Specifically, the alarm will trigger a loud-as-fu#k 120db siren that will draw an instant sea of eyeballs to the thief trying to steal your bike.

There’s an internal micro controller in the device to keep it from going off at random, or any time it detects a minor, harmless vibration. In terms of activating or deactivating the alarm, users need only position the radio-frequency identification tag as close the Bikealarm’s security enclosure as possible.

In terms of how long it’ll last, the device is powered by a rechargeable battery, which gets plugged in using a standard USB wire.
