Die elektronische Schaltansteuerung Rohloff „E-14 2.0“ kann mit der Neuen APP E-14 2.0 bei eBikes mit dem Bosch Smart System zum Einsatz kommen. Beim Bosch Smart kann nun erstmalig eShift zusammen mit ABS-System kombiniert werden. Antrieb und Schaltung kommunizieren miteinander und synchronisieren den Schaltvorgang. Das Ergebnis: ein leichtes, sehr schnelles und effizientes Schalten mit zusätzlichen Komfortfunktionen wie Auto-Downshift und Multishift. Als Ergänzung zu allen E-Bikes mit leistungsstarken Mittelmotoren ist die Rohloff SPEEDHUB als einziger dauerhaltbarer Fahrradantrieb ideal. Mit der neuen Rohloff APP E-14 2.0 für iOS, können individuelle Einstellungen vorgenommen und Servicefunktionen genutzt werden: • Auto-Downshift (Gang 4 bis 9) einstellbar, • Schaltung invertieren / Schaltrichtung (+/-) kann geändert werden, • Multishift deaktivierbar, • Servicefunktionen sind direkt online verknüpft (Feineinstellung/Kalibrierung der E14, Fehlerdiagnose, Softwareupdate, Handbuch).
