It’s small, sleek and enables you to alert distracted drivers and pedestrians to your presence. Featuring improved internal components and a brand-new style mount developed, your dB140 is better than ever: rock solid on the bars, easy to remove and interchangeable with other compatible devices. THE WORLD'S LOUDEST CYCLE HORN: 140 decibels is the equivalent sound of a jet engine and is 4 times louder than the nearest competitor. You can alert drivers of cars, buses, lorries & pedestrians to your presence. It has two sounds - a piercing 'road' mode (140dB) and a lower pitched car horn sound (121dB) for cycle paths. The remote trigger means it is safe and easy to use when braking, while being easy to install and remove thanks to the detachable style mount, the dB140 fits all bikes. Completely weatherproof (although not submersible), the dB140 is a potentially life-saving accessory when riding in towns and cities. TWO UPDATED STYLE MOUNTS INCLUDED: To ensure a perfect fit with all handlebar sizes two mounts are included - one mount for bars with a diameter of 22-26mm with 4 differently sized spacers and a second dedicated 31.8mm diameter bars (road bikes). You can use your spare mount on a different bike so you can easily swap the dB140 from one bike to another. IMPRESSIVE PERFORMANCE: Featuring two horn modes; 140dB and 121dB respectively, the dB140 requires uses 2 x AAA batteries which last for up to 12 months of normal use (6x 1 second blasts per day). The dB140 makes riding in town safer and less stressful: no need to shout, no need to swerve, no more emergency braking. Ride safely. According to ROSPA, 57% of cycle accidents occur because the "driver failed to look properly". To put this another way, if cyclists used horns to alert drivers to their presence it would prevent more than half of all serious cycle accidents. Be heard. Choosing to ride a bicycle shouldn’t mean sacrificing your safety. All other road vehicles must have a horn by law. That’s where the dB140 comes in. Equipping cyclists with a horn that can be heard by all road users, the dB140 ensures you’re always heard. Always ready. A critical part of the design, the remote trigger ensures you can operate the horn and brake simultaneously. Simply fit the remote trigger where your thumb rests on the bars. Enjoy the ride. The dB140 gives you the ability to let other road users know you’re coming and that alone makes cycling much less stressful. No more shouting, fewer emergency stops and more time spent enjoying the ride.

I'm worried it will be stolen off his bike though... is this easily removed and stolen?** A: Yes, you have to remove it a half turn to pull it off to install batteries unplug the button rotated, 180° and stick it in your pocket unless that person gets mugged it won’t get stolen **Q: Is it possible to get a longer cord? I want to mount it on my seat post facing backwards so I can alert cars coming up behind me.** A: No idea why Maurice Pinder would take the time to provide you with false information. “DB140 EXTRA LONG TRIGGER 150CM (5FT)” Hornit most certainly makes a longer trigger. You can easily purchase the item. **Q: Is it easy to replace the batteries while the horn is mounted or does the horn need to be removed to get to battery compartment ?** A: Yes it is easy to replace the batteries. To change the batteries, unplug the thumb button wire, then turn the horn body 90 degrees (quick release) and lift off the handlebar bracket. Replace batteries, then reverse the above procedure. Re-Plug the thumb button wire. The horn works very well and load enough for people to hear you coming. **Q: Unit works fine, but it sounds like there's a loose piece of plastic inside that rattles around when I shake the unit? Is that normal?** A: No! It should not sound like a rattle. If you are very concerned ask if you can return it for a replacement. Even if you are passed the return deadline, a reasonable company will allow for a replacement. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Es un salva vida *by K***N on 27 May 2023* Un espectáculo te salva la vida se escucha muy fuerte los coches paran y dan paso en las rotondas aun que sean con ventanas subidas.
