Engineers have created several ways for you to convert bicycle energy into power. But often, the options involve an expensive (and heavy) wheel buildout onto your bike. The Siva Cycle Atom is a generator that easily snaps onto your bike to charge electronic things like a phone, lights, and battery pack as you ride along. The website says, “We started Siva Cycle to transform the energy and passion of cycling into usable electricity for everyday.” They launched a successful Kickstarter campaign earlier this year to put the charger into production; the first round of chargers should reach people this month. The device not only represents a renewable energy solution for electronic devices, but also promotes a healthy lifestyle and helps reduce carbon emissions. Next time you need to recharge, consider grabbing your bike.
