DAWAY A14 110dB Electric Bike Horn – 5 Sound Modes, Loud Bicycle Handlebar Alarm Bell with Free Screwdriver, Ideal Gift for Kids & Adults – Safe & Easy Cycling Alert

I recently bought another recumbent bike and didn’t want to put an AirZound air horn on it because I didn’t want the bulk of the AirZound’s reservoir on this sleek “speed” bike. The AirZound is otherwise the best bike horn I’ve ever used because it is light, requires no batteries, is very loud, and its sound is not so high-pitched that car drivers ignore it.This electric horn uses two AAA batteries (not included). To install batteries, use the included screwdriver to open the battery compartment door on the bottom – that’s right, they include a screwdriver but not batteries. The bracket goes around whatever horizontal tube you have handy (hopefully not too close to where your head will be when you’re riding) and snugs up very tightly with the twist-ring. The horn itself slides onto the bracket. The trigger is easily wrapped around a spot reachable with a finger or thumb but be careful because the coiled cable between the horn and the trigger looks pretty flimsy; I wouldn’t put them at much distance from each other, don’t stretch it out too far. The red button on the top of the unit allows you to choose from among 5 different tones and patterns of sound.All the tones are pretty high-pitched but are all VERY LOUD. At a distance or through barriers (like car windows) where the volume won’t be perceived as very piercing, one or two of them probably sound like bird calls so I wouldn’t recommend using those. A small speaker just can’t produce a sound that is both low-pitched and loud and this is why these small electric horns always produce these high-pitched sounds instead of something like the tone of the AirZound or a car horn. The tone I have selected sounds like a warning buzzer, with a little similarity to the alarm sound of a large truck backing up.I don’t expect to get the attention of cars with this Hornit knockoff as easily or as well as I do with the AirZound: It’s just as loud but not as low-pitched so it won’t be mistaken for a car horn. But this electric horn doesn’t take up the kind of space on my bike required by the AirZound’s air reservoir plus the trigger can be mounted a little way from the horn instead of being permanently attached directly to the horn as is the AirZound’s. I don’t mind charging up the AirZound’s reservoir regularly (I don’t use it much but boy I’m glad I have it when I do need to use it) but for those for whom pumping air into a bottle is an annoyance or who run out of air during a single ride (I feel sorry for you, your traffic conditions must be truly horrible), then this battery-powered horn is a good alternative. Unless you’re leaning on the trigger all the time, the battery should last for months, maybe a year.Be a good citizen and get yourself a little bell or squeeze-bulb horn to supplement this LOUD electric horn. Using something like this electric horn on nearby pedestrians, joggers without headphones, or other cyclists is just obnoxious and startling. Save it for dangerous situations involving motor vehicles or dummies who can’t enjoy the outdoors without buds blasting noise into both ears.edit: I bought one of these a year or so ago and while this newer one is identical in every way in terms of its appearance and operation, the tone patterns are a little different. Not worse or better, just different.
