Just about as hard as it would be for the thief to take it off.

Even if you installed a tracer inside the seat tube where a thief would be unlikely to look for it, you still have the issue of power. Auto/motorcycle LoJack devices are powered off the vehicle's battery. Add a battery onto a bicycle, and it could weigh more than the U-Lock, plus you have to find a place to put it where the thieves still won't see it.

Pink, I'm sorry that happened to you. Thieves DO s*ck.
