The Pedalite. A battery-less pedal light incorporating flashing LEDs which operate automatically using the motion of the pedals as the power source. Yes guys, excellent idea and clever tech indeed. Go to the front of the class immediately. $86.48/£59.99 a pair.
Pedalite multiplies the spindle rotation using a gearbox and generator to convert rotational energy to electrical energy. Sufficient energy is available to energise the LEDs immediately and charge a storage capacitor. The capacitor provides residual energy enabling the pedal to flash when the cyclist freewheels or stops.
