Here we have yet another environmental friendly gadget that runs without any batteries whatsoever. This time it’s something to use for your bicycle.
The splash-proof Bike Dynamo Flashlight 3-LED ($10) is the type of product where you have to wind it up to generate power for the LEDs (yet again no info on how much cranking you need to do to get some light).
It’s 6.5cm long and can be removed from the holder and function as a handy flashlight. There are three different modes to choose from: 1-LED, 3-LED and Flashing 3-LED.
