HyMini Personal Wind Turbine

Comes with a bike mounting bracket and connectors for iPods and most mobile phones. If you are lucky enough to live in a country that’s windy even when you’re not moving, it can charge your goods all the time, so it’s ideal for camping and almost an incentive for cycling into the wind.

iH85BX Bike to Beach Speaker System for iPod

Unless you’ve got a taste for hospital food, headphones on a bike are a daft idea. This speaker enclosure for iPods means you can listen to ghetto blasting floor shakers, or that eight-CD language course, while on two wheels. It attaches to the frame and includes a handlebar-mounted remote control.

Air Zound 2 Air Horn

If the polite ding-ding of the traditional bike bell just isn’t getting the message across, this 120 dB air horn should ensure people know you are coming. It’s powered by compressed air, so can be recharged using a bike pump and comes with a volume control, but if you’re the sort of person who puts an air horn on their bike, we’re not sure why.
