When I was first putting together my motorized bike, I bought an $8 kit off ebay that contained turn-signals, a functioning brake light, and a horn. While I'm still satisfied with the former, the electronic horn was a bust. When I first put it on my bike, it sounded loud. That was before I started the engine. After a week of riding with it, somehow the vibration caused the speaker to rattle and now it doesn't work at all.
The Airzound bike horn, however, is the perfect solution. It's an air-powered horn, like an airhorn that you would use at a sports game. But why not just use the cheap air-horn that you'd bring to a sports game? Well, you could. But the Airzound doesn't require cartridges or batteries; It includes a pump to charge it up, and it lasts up to 30 blasts per charge! And it's 115 db loud! This is the best bike horn I've found, and it's certain to increase your presence on the road!
Here's a video of it in action!
