I bought a "leftover in the warehouse" wheel with an unbranded 26" rim and a Shimano DH-3D30 hub (6v, 3W).
What's the recommended mid-range option for lights and USB? I've got plenty of Magicshine MJ808 clones so something that would allow me to run those would be ideal.
Does anyone know of a graph of wheel speed (rpm?) vs power output (watts) for this hub?
Never owned a dynamo, I have no idea what I'm doing.
