http://www.thinkbiologic.com There's nothing we like better than clean energy. The Joule II dynamo hub wheel set has a built-in generator that produces electricity when the hub rotates while riding. Designed to fit 74 mm forks, this wheel set features one of the smallest, lightest dynamo hubs on the market.
Correct me if I'm wrong, the faster you run the more energy you can produce which means the light can be brighter?
