The BioLogic Joule HG On/Off dynamo hub is a bicycle dynamo hub that features a switch on the side that can be rotated “on” or “off”. In the “on” position, the Joule HG is one of the most efficient hubs on the market. In the “off” position, the magnets are pulled away from the core of the hub so that there’s practically zero extra drag when riding. Compatible with the BioLogic ReeCharge Dynamo Kit and BioLogic Power Pack and standard dynamo lighting options.
