The Bike Horn Amplifier for iPhone 4 can be strapped to your bicycle so you can listen to music on the move. It requires no electricity or batteries to power and it's handsfree. This incredibly simple product works just like a gramophone or trumpet by automatically amplifying the iPhone 4's sound by 13 decibels.

The Bicycle Horn Amplifier provides a washable, dirt, scratch and splash-proof protective cover for your iPhone 4. The sturdy velcro strap fits most bike handlebars and holds the mobile in place allowing you to listen to music or have hands-free conversations whilst cycling.

You could also use the iPhone 4 GPS function to verbally navigate you through the streets! The strap holds your iPhone 4 vertically or horizontally in place like a bracket and the Horn casing has an opening for your charger to plug in.

Even though listening to earphones whilst cycling has yet to be outlawed. Statistics show that accidents and deaths are caused as a result of earphones cancelling out the sound of oncoming traffic.
