The Epoch Times ran this photo of community power generation with a tandem bike after Sandy and many bike commuters are likely wondering how they can power their own devices with a bike. You do so while riding with a dynamo hub or a stationary trainer like this one from Field Studies that was seen on the Climate Ride.

At Bike Hugger we travel with Biologic’s Reecharge system. The hub charges a battery that powers your phone, as described in this video.

We’ve ridden on tour and vacation with the Reecharge system and will do so again this Winter, in Maui. Would also lend our legs to a community charge station and share our off-the-grid, pedal power.

Find dynamos online or at your local bike shop. Expect to spend a couple hundred dollars on the hub and converter.
