Sinewave Cycles Reactor Dynamo Charger


Product Overview

The Sinewave reactor converts the power from a bicycle dynamo hub for use in charging electronic devices such as phones, GPS units or separate cache batteries. Designed to replace the top cap of a 1" or 1 1/8" threadless (aheadset style) stem. If you have a quill stem the reactor  will not work; get the Revolution instead. The only thing that will be visible is the 9.8mm tall cap which houses the USB port.

Our very own Ryan King did a detailed review and installation guide on his The Flying Arrow blog.
