I commute through sketchy areas sometimes; having a loud deterrent on the bike reduces my anxiety and actually changed how often people approach my ride.

I tested it in a parking lot and the sound stopped someone fiddling with my lock; the remote is small and works from a good distance.

Common Questions About Your eBike Horn and Alarm

Clear answers to help you install, use, and trust the product with confidence.

How loud is the horn and will it startle people?

At 125dB the horn is very loud to ensure safety in traffic and crowded areas. Use short bursts to warn others without prolonged alarm. The intensity helps prevent accidents and deter threats.

How long does the battery last between charges?

The 1600mAh battery supports about 2,000 horn beeps or up to 150 hours in alarm mode. Typical commuting use can go days between USB charges, reducing maintenance worry.

Is the unit weatherproof for all-season riding?

The alloy housing is water splash proof when mounted. It holds up to rain and road spray, giving reliable protection through wet commutes and unpredictable weather.

Can I install it myself on different bikes?

Yes. The included mount fits 24-40mm tubes and installs quickly with basic tools. The compact design works on handlebars or frames for flexible placement.

What do the two remotes control and are they easy to use?

Two remotes control horn and alarm modes independently. They pair quickly and let you trigger warnings or a full alarm from your handlebars or pocket for instant response.
