My bike bites back. See:

http://thorncyclesforum.co.uk/index.php?topic=3930.msg21571#msg21571 Still in a humorous vein: one of my hobbies is UHT (ultra high tension) thermionic tube audiophile amps with up to 2000V on them, and electrostatic loudspeakers with 5500V on them; even my electrostatic headphones have 600V between my ears -- they sound particularly good on Gregorian chant: nearer my God to Thee!
https://www.audio-talk.co.uk/fiultra/JUTE%20ON%20AMPS.htm I build my own UHT amps and rebuild the QUAD electrostatics as required.
So I am, albeit always warily, at home with electrics that can and will kill the careless and the uninvited. Sometimes I wonder if one could get away with giving a bike thief an electric shock, nothing lethal, just a very low current electrostatic sting six inches before he even touches the bike; a ring of security. (When I market it, it will of course be as
The Ring of Fear!) Most tourers' bikes have a hub dynamo and when it isn't required for some other purpose like the lamp, it can charge up the capacitor that will power the security device. What I have in mind is that the would-be thief dismisses the first sting of electrostatic shock as a natural event familiar to us all, but that the capacitor will recover fast enough to give him a second hit, and a third and a fourth, until even the dumbest drug addict grasps that the shocks are aimed at him, that they will get very personal, even intimate, if he tries to ride the bicycle, and that he should move away right smartly.
It's a pity the police are so humourlessly woke these days.
Still, the n'lock is proof that not all good security devices need be boat anchors.
