Has anyone ever considered engineering a disable feature into bikes? What if there was, for example, a lock for the crank that would require too much work to defeat/break. The thief wouldn't steal the bike because his costs/time/difficulty would go up. Car stereo manufacturer's had this same issue a couple of decades ago. One brilliant solution was a removable faceplate for the the stereo. The owner just pulled that out (about the size of an iPhone 5) and took it with him/her when leaving the car. Another solution was to put a matching chip in the speakers...if the stereo was stolen and connected to an unmatched set of speakers, it wouldn't work. Let's get creative and end bike theft!
