The Sonder Juice dynamo hub can power your lights and keep your electronic devices charged when you are far from civilisation, when batteries and plug sockets are a distant memory. All you have to do is keep pedalling!

The Juice is a highly efficient, low drag device with a 6V / 3W output. Suitable for road, gravel and mountain bikes, it's tested down to -20°C so you can rely on pedal power even in extremes conditions.

We do not recommend charging your expensive electronic gadgetry directly from the hub dynamo. It provides an unregulated AC output that you will need to convert via a USB charger to provide a reliable DC current.

The Juice Boost uses Boost standard spacing and is compatible with both the Sonder Nova and Sonder Alpha wheels.
