More than a horn.
A front light, an alarm and a rechargeable battery—all part of the same compact setup.
Can I use my own sounds?
Yes. Disarm the horn, connect it to a computer with a USB data cable, and copy WAV or MP3 files to the removable drive. Safely eject before unplugging, then select your sound using the horn’s controls or remote. The horn is inactive while connected to the computer.
Will it fit my handlebars?
The supplied mount is specified for round handlebars 22–32 mm in diameter. Use the rubber ring for bars 22–25 mm. Measure the mounting area and check there is room for the horn and controls. For a different bar shape or an uncertain fit, contact us before ordering.
Is the wireless remote included?
Yes. Each set includes one wireless remote. The two-pack contains two horns and two remotes.
What batteries does it use?
The horn has a rechargeable 1200 mAh battery. Each remote contains a CR2032 coin cell. Keep coin cells and the remote away from small children.
Does the alarm replace a bike lock?
No. Use a physical bike lock. The alarm is an additional feature, not a guarantee against theft.
Does the demo show how loud it is?
Playback depends on your device and volume settings. The demo is not a measured decibel level.
How much does delivery cost?
Available delivery options and charges are shown at checkout before you pay.
