One of the biggest challenges of cycle-commuting is making your presence felt above the din of traffic. The Air Zound bike horn emits a 120 decibel blast that will let even the most inattentive driver know you're out there.
The horn is handlebar mounted, and the air reservoir is attached to your water bottle cage. Easily fill it up using a bike pump or a compressed air cylinder. Each refill lasts for approximately fifty blasts.
