Dahon has released their latest bicycle accessory, the BioLogic FreeCharge that charges up your USB-connected devices each time you take your bicycle out for a spin. This tiny, silicone-encased box will be connected to your bicycle’s generator hub, where it is built around a battery that has generic circuitry to smooth out spikes and dips in the FreeCharge’s output to make sure your device gets consistent juice without getting fried. A full charge will take around 3 hours of cycling, and we guess this is good enough for those who would love to take long cycling trips and make sure that their iPod remains juiced up to provide more inspirational tunes to the rider. The BioLogic FreeCharge is tipped to be released in March next year for approximately $100.
