Make some noise for the bicycle air horn

Inattentive motorists can kill cyclists. The Air Zound bike horn emits a 115 decibel blast that will let even the most distracted driver know you're there. The handlebar-mounted air horn draws from a air reservoir attached to your water bottle cage or other convenient location using the velcro provided. After around 50 blasts of the horn the reservoir needs refilling using a standard bike pump.

If the 115db volume is too much, it can be moderated with the turn of a switch.

World's loudest bike horn

City cyclists who battle to get themselves noticed on the roads can resort to the ultimate deterrent against inattentive truck drivers; a bicycle equipped with a horn that is louder than Concorde.

The Hornster bicycle was developed by us at the ETA to highlight the dangers that cyclists face on city roads. Trucks are involved in over half of cyclist fatalities that occur in London.

The triple air horn fitted to the bicycle is an Airchime KH3A from an American locomotive, which has been adapted to run off a scuba diving cylinder.

The Hornster is so powerful that at a distance of 100ft it is far louder than a standard truck horn and more than noisy enough for a cyclist to make themselves heard above the din of the urban jungle. A spokesperson for the ETA said: “The same quietness that makes bicycles such a civilised way of getting around makes them vulnerable to inattentive motorists – the Hornster is a wake-up call for drivers who don’t pay attention to bikes.”
