Biologic Joule Hub Dynamo 20H & Hella Micro FF Halogen Light Set

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. Come as a set with Hella FF Micro Halogen light. The smallest and most elegant halogen dynamo light we've found, the Micro FF perfectly matches the compact design of our bikes. The Micro FF emits a clean and bright light for riding at night. Hella is one of the world leaders in performance automotive lighting and the Micro FF is an example of their engineering and design excellence. With on/off switch. *Suitable for all 16", 20" and 26" bikes.
