Could I Use RFID to Prevent Bicycle Theft?

I am sick of having my bike stolen each year at Burning Man. Is there a chip that consumers can buy that offers a four-mile range or something close to that? Thank you.

Unfortunately, no, there is nothing that has that kind of range that could be used for a consumer application. There are Bluetooth beacons that can alert you if something is moved further than about 50 feet away, but it would not work at a large event where your bicycle would be locked up far from where you were watching or participating.
