There are bicycle horns and then there are serious bicycle horns! DYIer Chad Thoren – known to his friends (and apparently foes alike) as The Chadster – outfitted his bicycle with a dual trumpet horn from the locomotive! He connected the born to a tank filled with compressed air, which he says produces much louder results that you get by just honking up the horn to an air compressor.
No doubt this had some serious weight to his cruiser bicycle, but is the video shows we doubt anyone won’t know The Chadster is coming!
