Your taking the responses the wrong way.. 1st . Its not like someone is going to load your car into a minivan and drive off 2.nd If someone is going to steel your bike, most likely it will be more then one person loading it up and say your pager does go off and you go out there.. like what has already been said. (they either throw your bike to the ground and you pay your $500 deductable to fix $400 in damages., or they beat your ass and steel your bike anyway. or if your really unlucky, they kill you so you cant report anything to the police.) The point of the situation is, IF SOMEONE WANTS YOUR BIKE, THEY WILL TAKE IT.. my life is not worth coming out to fight a bunch of d-bags trying to take my bike. try and think about the type of people your dealing with. You have insurance for just that reason.. so based on what your saying,, fuck buy the alarm and cancel your insurance. 9 times out of 10, you will make out better with the insurance company then what you would if you tried to sell the bike.. so with the money you get, you could go and buy a brand new one.
