This is actually nice to use on bike trails to let the walkers know you're coming with the funny friendly sounds it makes. This is the Hornit Mini, it is a battery operated electric horn for bicycles and scooters. It's loudness range is 75-80 decibels. It fits all bicycles and scooters. The two stretchy wings lock it securely in place no matter what size handlebars you have. I also show you how to replace the battery. It uses two AAA batteries.
