Stun gun bike

nice

a pager in place of the cell phone would be better cost per month

It's a pay as you go, so there's no monthly fees.

Hopefully, the lesson won't be how to sue someone for booby trapping, which is illegal in many states (maybe all, for all I know). REALLY hopefully the guy won't have a cardiac event due to the shock.

What I would do instead is take one of those dye packs that they hand bank robbers, and integrate it into the seat. Fix it so that it fires some number of seconds after someone sits down on the seat. Add in a proximity switch of some sort (kind of like the immobilizer keyfob for a car), so that if you have your little keyfob with you, then you will be able to ride the bike without the thing firing off.

The only issue I see is a wrong number, or a solisisation call, that give a whole new meaning to wrong number.

That and the contact points on a bike are where, hands, feet, and taint (OUCH)

Simplicity has it's merits.
