Hornster bicycle has a horn louder than Concorde

275x250.jpg Many city cyclists struggle to get themselves noticed as they do battle with cars, buses and lorries. But not any more, meet the Hornster ... a bicycle equipped with a horn that is louder than Concorde.

At close quarters the Hornster bicycle emits 178 decibels; a level of sound so powerful that if used in anger it could deafen any motorist who veered too close.
 
The Hornster bicycle was developed by the Environmental Transport Association (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. 
275x250.jpg It 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.
 
The Hornster is the brainchild of Yannick Read, who 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.”
 
The Hornster is sale for £4,995.
