Imagine if you could have the simple control of a car/motorbike horn on your bike…
If only there was a way to honk at inconsiderate drivers who bully-and-run in rush hours!

The unique car-power Bike Horn 4.0 is not only the loudest bicycle horn but is your safest riding bet! It packs 90 dB CarWindow-penetrating of familiar horn-sound to people in the car and jaywalkers!

ROCKBROS Electric Cycling Bell 90 dB Horn Rainproof MTB Bicycle Handlebar Silica Gel Shell Ring Bike Bell Bicycle Accessories
This horn rings 3x louder & generates an actual road-car honk sound!

Is shouting really an option for you, riding in an Urban city? That’s just useless + icky!

Make your rides fun with 3 different sound options!

Raining? No problem! We’ve made this weather-resistant for you!

Taking feedback from cyclists for our previous Bicycle HORN, we decided to work hard at incorporating the perfect design, with a new minimalist style, and reduce the weight by more than half while maintaining the LOUD car-horn sound!

The new Bike Horn is not only loud, but its lightweight high-impact engineering thermoABS polycarbonate will never compromise on your efficiency and the 280 mAh battery will keep you charged for the road!

You can rely on its improvement to get you in time through all the rush hours.

It hangs downward, so the small 3.5 *3 cm size leaves plenty of empty space on your handle-bar!

It’s not a bell; it’s you on the road through rushing and honking cars.

Keep your minimalist style, no more stress at work, commute easier, reach on time and fresh, and honk those jay-walkers and car-bullies away!

Sound like a car. Ride safe.
