The Sinewave Reactor's USB port replaces the bike's stem cap
Power is provided by a third-party generator
The Sinewave Reactor's electronics are contained within its cylindrical body, which sits down inside the tube
While companies such as Dahon and Nokia already offer products that let you charge your phone with power generated while cycling, both systems do somewhat clutter up the handlebars and stem. Sinewave Cycles' new Reactor, however, is mostly integrated into the bike's existing steerer tube, keeping external hardware to a minimum.
