More complicated, but better:

Scorpion Alarm (i500, i600, i900) or equivalent. These alarms have three dimensional movement sensors and optionally perimeter alarms, plus remote notification to a pager-like device. The instant someone starts to screw with the bike, your pager goes off. Expect to pay $250 (used) to $500 (new, top-of-the-line) for this kind of solution with remote notification.
