QUARTZ

QUARTZ is an innovative drive unit for e-bikes and e-cargo bikes. It is the native integration of a planetary gearbox and an electric assistance motor in a single mid-drive unit. It adds full-time gear shifting, ease of use, reliability and low maintenance to e-bikes. By uniting gearing and motor in the same compact mid-drive unit, we allow the whole bike to have better dynamics, simpler rear wheel transmission, possibly with the benefits of a belt. And since QUARTZ is very light and compact, it integrates very well in the design of any bike. With QUARTZ, we hope to contribute to the emergence of a new generation of e-bikes which shall be the cornerstone of modern personal urban mobility.

Jury Statement

Vor allem für die Nutzung in E-Cargobikes fanden die Juroren die Antriebseinheit mit integriertem Sechsgang-Getriebe sehr überzeugend. Das robuste und wartungsarme System ist für City- und vor allem Leihbikes wie geschaffen.
