COOLWHEEL Bike Bell Electronic - Mini Bicycle Horn 130 db Loud USB Rechargeable Handlebar Cycling Alarm Alert Ring for Mountain Bike/Road Bike/BMX/MTB

This bike horn is loud, easy to charge, easy to mount and has a 3 level volume control which is nice if you don’t want maximum volume all the time. The only thing that could be better is that the horn sound is just a single constant tone instead of a tone with alternating high and low pitch tones. I believe that a tone that alternates would be better to get someone’s attention but this horn works and it’s not worth subtracting a star.

Horn is A Blast. Happy Holidays!!

I am very pleased with this USB charged bicycle horn, however - it must be made in China: as a mechanic I know sometimes things don't fit perfectly produced there. On the one I purchased, I was forced to use a lady's fingernail file (emery board) to go around the male USB charging plug a number of times before it would fit into the connector port. After that, it charged up in about 5 mins going from the tiny (red) indicator light - to the (green) fully charged light. The horn is compact but approx 350 DBS loud! IT IS A GREAT HORN - if you know how to get the connections to mesh together, so it only gets a four-star rating.

But it is a touch harsh.

Thought it had a selection of different tones
