Back in the days of antiquity of my youth we had bike sirens that were about the size of a baseball and mounted to the fork of bikes. They had a knurled wheel like a bike generator which when pulled against the moving tire with the attached chain made a pretty audible siren sound. We kids thought they were great shakes, however the St.Pete police didn't agree and soon they were illegal. I would like to make one of these but have been unable to find any information. Hoping that someone on this forum might be able to shed some like on this.
