Siva Cycle Atom charges your phone by pedal power as you ride

Want to arrive at work in the mornings with a fully charged smartphone? You will be able to soon if you cycle to work, as Siva Cycle has reached the funding goal on Kickstarter for its Atom bicycle generator with 22 days left of the funding phase still to go.

It's essentially a simple piece of kit. There's the generator part that powers a 1,300mAh rechargeable lithium battery using the revolutions of the rear wheel on a bicycle, and there is a USB port into which you can plug a smartphone or other powered device. And what's more, the battery pack is detachable so you can continue to charge your device away from the bike.

"As you ride, it harnesses the kinetic energy you generate, either directly charging your device or storing the energy in the detachable battery pack, giving you on-demand power whenever and wherever you need it," says Siva Cycle on its Kickstarter page.

The generator part weighs only 300 grammes, so you won't even know that it's there. It's also easy to fit on any bike with rim-brakes, although it does require a minimum of 20mm of space between the rear dropout and hub flange (where the spokes mount), with the latter needing to be 3-inches in diameter. A future model for bicycles with disc brakes is in the pipeline.

Currently being shown at TechCrunch Disrupt NY 2013, the Siva Cycle Atom will cost $105 when released. It's currently available for $95 on the Kickstarter project page to backers, and is expected to ship in November.
