                | Joule Hub Dynamo |   
                |  |   
                | MSRP: US$75 There's nothing we like better than clean electricity. A hub 
                  dynamo is the most efficient way to generate electricity for 
                  your bike light. The hub is embedded with a series of small 
                  magnets that generate electricity when the hub is turned while 
                  you ride. So you can say goodbye to batteries. The Joule hub 
                  features a polished aluminum hub shell and is made to our 74mm 
                  compact width specifications. It is one of the lightest hub 
                  dynamos on the market and also one of the most efficient. Comes 
                  as an assembled front wheel with our Kinetix Comp rim and stainless 
                  steel spokes.
 
 
   *Suitable for all 20" bikes
