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.

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.

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.
