The idea behind my concept is to have a device with a speaker and locking system that will prevent the bike pedals from turning. The device will attach to the bikes down tube and the other half will then be attached to one of the pedals. (This is illustrated by the green box on the bike) The cable will act as a relay conecting the two parts. As the cable is connected to the pedal part it will act as a lock in preventing the pedals from turning but also sound an alarm if a thief is to cut the link between the down tube part and the pedal part.
The device will come with a key chain receiver to turn on and turn off the device. That way one can remove the cable from the pedal.
The main goal was to keep it as simple as possible and yet make it loud enough to deter thiefs.
