For the cycling type of robbers, you can put something in the velocity meter (yep, a $1100 bycicle must have it, eh?) and count 2 or 3 turns. If the alarm is activated, and it sees 2 or 3 turns in more than a second (the man must be running - children or someone who is bothered by the position of your bike will not run with it - will only change it's place slowly), it fires the alarm. But how would it hurt and sound like hell? If you put a power tweeter, surely it will be kicked off before you ever hears it. Of course it could trigger a remote alarm, but people wouldn't see. A GPS antenna below the seat with a simple transmitter, would transmit it's position to your "remote module" or call police with a voice synthesizer (ISD chips anyone?) transmitting via voice the latitude and longitude of your belowed bike.
