Its remote trigger allows safe, one-handed operation, making it an essential, weatherproof safety accessory for urban cyclists seeking to reduce accidents and ride stress-free. ## Description Product Description THE WORLD'S LOUDEST CYCLE HORN The patented Hornit dB140 is the loudest cycle horn on the market and puts the cyclist in control of their own safety. It’s small, sleek and enables cyclists to alert distracted drivers and pedestrians to their presence. Why the Hornit dB140? 140 decibels is the equivalent sound of a jet engine and 4 times louder than the nearest competitor. You can alert cars, buses, lorry drivers & 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 Garmin 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. No more shouting, fewer emergency stops and more time spent enjoying the ride. 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! 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. Two Garmin 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 for 31.8mm diameter bars. You can use your spare mount on a different bike so you can easily swap the dB140 from one bike to another.

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 ### ⭐⭐⭐⭐⭐ hornet bike horn *by M***L on 22 June 2026* good bicycle horn ,loud enough to be heard on the low setting, east to Mount on bike . ### ⭐⭐⭐⭐⭐ THAT IS LOUD! Loved it *by V***N on 2 June 2025* THAT IS LOUD! If you're a commuter, it could save lives! Batter lasts long, easy to install on the bike and it fits a big variety of handlebars, the button works fine, it really alerts people and cars, very loud, the loudest I ever had considering the battery and size. Really recommend it. ### ⭐⭐⭐⭐ It is very LOCAL loud and hurts your ears!. Great otherwise. *by Y***! on 9 May 2026* This is a review of the Hornit dB140 Bike Horn V3. I bought this cycle horn because I wanted something that could warn drivers if they had not seen me and help prevent accidents. At around £30, the product is expensive, but I do value my safety. I already have a regular bell, but motorists cannot hear it. The regular bell is fine and gentle for riding in parks or quieter areas, but largely useless in busy road traffic. Pros and Cons Pros: It comes with two handlebar mounts. Cons: Battery compartment: The battery compartment requires a very small screwdriver, which is a major flaw if you need to change the battery on the go. It uses one of those tiny watch-style screws. I managed to open it with a regular narrow regular screwdriver head, thankfully, but in my opinion it is a poor design choice. Uses 2 AAA batteries. Storage box: The supplied box is too tight. If you need to remove the horn, it can be difficult to put it back in again. Danger to hearing: This thing is loud. However, I think it is more of a “local loud” rather than sounding like a full car horn. I could see it hurting my eardrums, so it is best used sparingly Settings: It is hard to tell which sound setting is currently selected. You will still need a regular cycle bell. I use the bell for pedestrians and the Hornit for road traffic. ## Frequently Bought Together - Hornit dB140 Bike Horn, Upgraded V3 Model, World's Loudest Bicycle Horn for Increased Rider Safety, Remote Trigger and Upgraded Mounting System Included - Lamicall Bike Phone Holder, Motorcycle Mount - Motorcycle Phone Holder, Handlebar Cell Phone Clamp, Scooter Phone Clip for iPhone 16 Pro Max/Plus, 15 Pro Max, S10, S20, More 4.7" to 6.8" Smartphones - BriskMore Handlebar Bike Mirror, Scratch Resistant Glass Lens, Ajustable and Rotatable Safe Rearview Bicycle Mirror --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/502508382-hornit-db140-bike-horn-140-db-two-sound-modes-ip44](https://www.desertcart.sn/products/502508382-hornit-db140-bike-horn-140-db-two-sound-modes-ip44) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-08-15*
