Like a car-charger for your bike, the Siva Cycle Atom uses your own momentum to charge your accessories. Attach it to your bike, and the battery begins to kick in as soon as you do. Once you've arrived at wherever you're heading, remove the battery, and plug your iThing into the USB port. Suddenly, all those miles are working for you in ways you could have never imagined. Now go Instagram that sunset. You've earned it.
