This pink bicycle horn is called "pink burst" because it has a unique burst shape cutout on the front of the horn where the sound emits! It measures approximately 5.5 inches long and 2.75 inches wide at the front end of the horn, and bears the "Makai" logo on the front end. If you're looking for a pink bike horn with a little attitude, this horn has got it. The sound that comes from this horn is a little squeaky and a litter higher pitch, and definitely gets loud especially when you squeeze hard. The horn itself is made from steel with a rubber squeeze ball on the rear-end. The adjustable mount is made from bendable steel and this horn can be adjusted to fit most common size bicycle handlebars.
