Seen at Eurobike: Biologic Joule 3

Joule 3

Joule III is a shiny, power-generating hub

This new Biologic Joule 3 arrived at Hugga HQ a few weeks ago and Tern is demoing it today at Eurobike. Eurobike is like the CES of the European bike industry and next month is Interbike for the North American market. As you can see in that photo, the Joule is significantly improved and much shinier than the version I rode with in Maui last year. The Joule II worked well powering the Reecharge case and the iPhone in it while I rode, but was a bit bulky and creaked on the road when engaged in power mode. As Tern’s PR told me

The BioLogic Joule 3 is the most up-to-date Dynamo hub on offer as it’s smaller, lighter, more efficient and powerful than any other available right now.

After lacing this dynamo hub to another wheel, I’ll ride it in Maui again. The full product details haven’t been released, but expect pricing at $150.00.


The Joule 3 just won a EuroBike award in the Design category.
