Siva Cycle Atom
Never let your smartphone, tablet, GPS, or other electronic gadgets run out of juice on a ride with Siva’s Atom. Strap this small, lightweight generator to your bike’s rear fork to generate power as you pedal, adding negligible resistance to your ride, then pull out the removable battery pack with an embedded USB port to charge your gear. Otherwise, it’s weatherproof to IP-4 standards, packs an under-seat UBS plug for use on the road, a LiPo battery, and enough power to bring a dead flat iPhone back to 70%.
