AirZound 3 Rechargeable Air Horn:
The worlds loudest bike horn, but dont take our word for it; see what a passionate user said about it:
""A big problem on the bike (especially when commuting or cycling in rush hour) is being cut up, being pulled out on or overtaken too closely. The AirZound is a fantastic and immensely loud bicycle horn. Bin that pathetic bell now and get one of these 115 decibel, rechargeable air horns.""
Requiring no batteries,no cartridges and refilling with a simple bike pump, the AirZound will definitely make sure you are seen and heard on your city commute.
