As long as you can lift a bike and stick it in the back of a pickup truck or load it into a van, bikes are going to be much easier to steal regardless of physical locking mechanism. But one interesting idea is some kind of electronic kill switch and GPS tracker, particularly on the electric bikes that have juice. I think that would be the direction I'd like to take anti-theft defences for bikes. But as you start adding more valuable components to bikes like batteries and motors, you will start getting bike chop shops like you have with cars.
