Tired of people not hearing you when you're cycling? This DAWAY A14 electric bike horn is seriously loud - we're talking 110dB, which is enough to get anyone's attention! It has 5 different sound modes, so you can switch between them depending on the situation. Maybe use a gentler sound in quiet neighborhoods and the really loud one in busy traffic. The separate control switch is super convenient because you can mount it right where your thumb can easily reach it without taking your hands off the handlebars. Installation is pretty straightforward - it comes with a free screwdriver and fits most bicycle handlebars as long as they're within 25mm diameter. So whether you have a road bike, mountain bike, or anything in between, this should work. It's powered by 2 AAA batteries (just a heads up - batteries aren't included), and they say the batteries can last up to 6 months with normal use. The whole unit is pretty compact at about 90mm long x 45mm wide x 35mm high, and it weighs only 96g, so it won't add much weight to your bike. It's also got IP4 waterproof rating, so a little rain won't hurt it. DAWAY focuses on outdoor products and they offer 6 months warranty, so if you have any issues, they've got your back. This is one of those accessories that really makes cycling in traffic feel safer for both kids and adults.
