Shimano Dynamo Hub

Shimano® 1.5W Dynamo Hub

Solar, wind, hydro...

This lightweight hub generates electricity to power your bike lights. Beyond creating your own green power, you'll be able to strike a few things from your to-do list because you'll never have to replace batteries on your lights or worry about recharging. Shimano's design ensures rotational smoothness and long life thanks to a clever internal sleeve that shuts out water, mud, and dirt.
