Detachable pedal-powered generator

    A pedal-powered generator with a removable battery will be designed to power smartphones or other USB devices.
    The generator will be lightweight, low-profile and easy to install on most standard bicycle frames. Its magnetic rotors will harness the kinetic energy of the moving bike, sending the charge either directly to a USB device or storing it in the detachable battery pack. The 500mA charge rate generated by the generator will be the same as the USB 2.0 output from a computer, enabling it to charge a device as quickly as a computer connection does.
