Make some noise with this awesome retro bike horn! If your regular bike bell just isn't cutting it, this air hooter delivers a seriously loud, distinctive honk that definitely gets people's attention. Made from durable metal and silicone materials, it's built to last through all kinds of weather and riding conditions. The total length is about 8.3 inches with a 2.2 inch diameter, and it fits handlebars up to 0.9 inches thick. Installation is super simple - just use a hex key or screwdriver to tighten the included metal mount onto your handlebar. You get to choose from several colors: Black, Red, Blue, Pink, or Green to match your bike's style. The sound has this classic, elegant tone that's much more effective than weak little bells, especially in busy traffic or on shared paths. It works by squeezing the rubber bulb, which means you can control how long and loud the honk is. Perfect for bicycles, mountain bikes, beach cruisers, and even some recreational vehicles. This isn't just a safety device - it's a stylish accessory that makes your bike stand out from the crowd while ensuring you can alert pedestrians and other cyclists effectively.
