Generate your own power for a front or rear light with the PD-8 Dynamo Front Hub.
With a dynamo hub, such as the PD-8 from Shutter Precision, and an appropriate light, batteries and plug in charging are a thing of the past. The PD-8 uses a high grade NdFeB permanent magnet to generate power as your front wheel spins. Its particular design achieves 72% efficiency at 15km/hr (more efficient than any comparable dynamo hub) from a package that is both very lightweight (410 grams claimed) and good looking. With an output of 6V3W the PD-8 meets the internationally recognized StVZO German requirements (approval number K845) and is compatible with 6-bolt disc brake rotors.
A wheel built up around a dynamo front hub is the perfect addition for a self-sufficient cyclist. Whether for extended tours, trips to lonely forest roads, or urban commuting, worrying about your light failing at the least opportune moment is a thing of the past, because as long as you're moving you generate all the power you need.
The Shutter Precision PD-8 Dynamo Front Hub is available in Black, Silver, and Red. 32 hole. 6-bolt disc brake. 410 grams.
