Don't let your smartphone, GPS, or MP3 player run out of juice while biking out on the trail. The Human Creations Bicycle Dynamo USB Charger Kit uses good, old-fashioned pedal power to generate enough energy to keep your devices fully charged up. Just install the dynamo on your bike's wheel, plug in your device to the USB port, and enjoy the ride. You're going to be pedaling, so you may as well convert that lost energy back into something useful. It's a great solution, but why isn't this technology just built right into newer bikes already?
