Here it is. The idea came from wondering how to make a low tech car alarm for a bike.

This is the personal panic alarm I bought off Amazon for about $14. It works by pulling the cord which pulls a key out of the unit activating the alarm. It can't be shut off unless you plug the key back in. To it I glued some velcro for securing around my bike and another strip to secure the cord to my tire.




For the pic I have it secured to the seat tube but on tour I fasten it under the saddle bag out of sight (there's a strap loop on the bag). When I lock the bike I just undo and refasten the velcro around the tire with no slack. If someone moves the bike it pulls the key. My bike is black and the cord blends in so it would take a bit of time to figure out where the noise was coming from or how to silence it. I also remove the chain from the chain ring so someone can't just ride away quickly.
