Lead-Free Pewter #1 USA Gremlin Bell Comes with a story card, key ring, and zip tie to connect it to your bike. Measurements: 1-1/2" tall x 1" wide. The Legend: Think Evel Knievel! Legend has it that a small bell attached to your motorcycle, close to the ground, catches the Evil Road Spirits. The Little Gremlins live on your motorcycle causing all kinds of mechanical problems. The cavity of the bell attracts these Evil Spirits, but the constant ringing drives them insane and they lose their grip and fall to the ground. (Have you ever wondered where pot holes come from?)
