Compatibility, Size and Fit
This horn is described for road bicycles, mountain bikes, and scooters, and the handlebar fit is stated as 22.2 to 31.8 mm in diameter. That makes the handlebar size the main check before buying.
The mounting method uses double-sided tape and a silicone ring. If you are choosing for a different bar shape, a heavily crowded handlebar, or a nonstandard setup, confirm that you have a clear place to mount the unit before selecting an offer.
What Else You May Need
The horn charges by USB and comes with a USB cable. If you plan to use it regularly, you will need a suitable USB power source for charging.
Before You Decide
Confirm the 22.2 to 31.8 mm handlebar fit, the 2 sound modes, and the alarm function before choosing an offer. If weather protection and USB charging matter to your setup, compare those details against how you plan to use the horn.
