The Voice / Serial Model / 2012

"The Voice" is a further development of our compact "The Sounder" model: evolved, larger, more powerful, build with highest quality components only for improved performance and sound quality. It comes with a integrated storage compartment. While "The Sounder" was designed as a compact, highly flexible, mobile and autonomous soundmachine for private use, "The Voice" was constructed to larger extent with corporate clients in mind: colours, for both bike and system, are fully customizable - sideboards and front area give ample space for logo application. "The Voice" is delivered firmly connected to a Bullitt cargobike. Its body is elegantly fit to the Bullitt cargo area, joining bike and system to an harmonious aesthetic and functional unity. Lightweight construction and a low-seated balance point support an easy and safe riding experience.
