The perfect "hidden" USB charger for bikepacking, cycle touring or the daily commute.
The Sinewave Reactor takes the performance of our Revolution bicycle dynamo powered USB charger and shrinks it into a package that fits above the star-fangled nut in a threadless steerer tube, with a pass through for the 6mm bolt. The only visible part is a custom CNC-milled stem cap holding the USB connector. The cap is only 9.8mm tall and available in silver, black and red. The Reactor is compatible with 1" and 1 1/8" threadless systems.
The Reactor is made in the USA.
