The folding bike specialists at Dahon have come up with an energy efficient way to charge your iPod, iPhone, MP3 player or handheld device – bike power. The FreeCharge transfers power from a bike’s generator hub to a high-capacity battery, which in turn supplies steady current to your USB powered small device.  The FreeCharge unit secures to the bike’s frame in a silicon case.  Duhon is including the charger on a couple of its bike models in the near future and as a stand-alone accessory sometime around March 2010 for an estimated $99.

Nice concept.   via: bikehugger
