This mini black-on-black bicycle bell is perfect for the bike rider that wants a small, convenient, yet stylish bell! This little bell weighs an ultra-light 0.6 oz and the metal black portion of the bell measures only approximately 1.3 inches wide, and less than 1 inch tall (not including mount). The bell is operated by pushing down on the small lever with your thumb and then releasing. The little plastic hammer hits the bell and makes a distinctive "ding" sound. This bell is a great way to get noticed without causing too much of a disturbance on the bicycle path. The adjustable black plastic mounting bracket will fit most standard size bicycle handlebars.
