How do thiefs typically steal a bike? Do they how wire it or just lift the bike into a truck or something and drive it off? Where I'm going with this is do things like disc locks really work? Also, if people do usually hot wire the bike would it be easy to put a switch on the power wire to the ECU and just shut it off to secure the bike. Seems that would take a thief too long to find (assuming you were descrete with it). Seems that would be cheaper than some of the complex alarms and maybe more effective as people know those alarms and how to disarm them.
