120DB Bike Horn Alarm - USB Rechargeable Electronic Bicycle Bell for Cycling Safety and Loud Road Warning Alerts

A thumb-flick, and the car actually hears you

A ping from a chrome bell dies about four feet from your front wheel. Inside a car with the windows up and the radio on, it never arrives. That is the whole problem with the bell you have: it is polite, and a door about to open into the lane needs a warning that carries.

This is an electronic horn instead. It straps to the bar next to your grip, sits under your thumb, and sounds an electronic siren rather than a mechanical ding. You keep both hands on the bar to use it.

It is small, about the length of your thumb, and it recharges over USB, so there is no battery hatch to open and no coin cells to hunt for.

Cycling safety you can hear: a 120 dB road warning alert

The manufacturer rates this horn at 120 dB, an electronic siren tone that carries the way a car horn carries, with the loud, urgent character of a road warning alert instead of a bicycle bell's ping.

One tap tells the driver edging out of a side street that you are there. Another tap tells the walker stepping off the curb. Drivers and walkers hear you before you reach them, and that is the reason to buy it.

Aim it down the road and tap

Point the speaker face forward, down the road, and tap. A short burst is all it takes to be heard by the drivers and walkers ahead of you. Save the siren for traffic, and use your voice on a quiet towpath.

Your thumb stays on the button pad beside the grip, so the warning comes the instant you reach for it.

Fits in about a minute, with no tools

There are no bolts and no clamp band. A flexible silicone strap threads through a lug under the horn, stretches around your handlebar and hooks back onto the lug. It takes about a minute, and it comes off just as easily when you park somewhere you would like to take it with you.

Because the strap stretches, it suits a range of round handlebars and stems, so it goes onto a commuter bike, a mountain bike, a scooter or an e-bike with the same strap.

The second mode: an alert tone for a parked bike

The horn also has an alert setting you switch on with the button pad when you walk away from the bike. It is what the word “alarm” in the name refers to.

Switch it on, lock up as usual, and your parked bike carries a loud deterrent tone: one more reason for someone to pick a different bike, on top of your lock. When you would rather take the horn with you, it unstraps in seconds.

Why riders pick a siren over a bell

A bell is a polite ping. This is a siren you control with your thumb: louder, more urgent, and aimed straight down the road. It is thumb-sized, there is no battery hatch, it recharges over USB, and the strap comes off in seconds.

Every order is covered by the Gear Elevation 90-day money-back guarantee, so you can mount it on your own bike and hear the difference on your own commute.

Be heard before you reach them. Add the 120 dB bike horn to your cart and ride with a warning that carries.
