Electrolyte Straßenfeger - Pedelec with a Revolutionary New Drive
System
The Straßenfeger is one of three e-bike models, which are equipped with
the new Electrolyte drive system. Motor, battery and controller are fully
integrated in an innovative single-sided swingarm, which drives the front
wheel. Because of the encapsulated design, the individual components are
better protected against dirt and moisture and require little maintenance.
