CLASS SPECIFICATION
' ' data-title='e*thirteen Base, 35mm Ø, 800mm Width, 20mm Rise, 9°'>The New Fab.4 ELB—Now Powered by Bosch
In our latest e-bike models, we rely on the newest generation of the Bosch Performance Line and Performance Line CX motors. The drive system has been optimized to combine high power density with a completely natural riding feel.
An Overview of the CX Technical Specifications:
Power and Torque: With a maximum torque of 120 Nm and a peak output of 750 Watts, the motor delivers powerful assistance under heavy loads and on steep terrain.
Support Factor: The system amplifies your own pedaling power by up to 600%. The sensors regulate power delivery progressively, ensuring the assistance remains completely controllable at all times.
Weight Optimization: The total weight of the motor has been reduced to approximately 2.8 kg. This contributes to agile handling and a well-balanced overall center of gravity for the bike.
Flexible Battery Management: Up to 800 Wh Capacity
Various battery options are available to power the Bosch drive system, allowing you to perfectly match the range to your individual riding profile.
Standard Equipment (600 Wh): The base configuration provides a solid foundation for everyday riding and sporty day tours.
Optional Upgrade (Up to 800 Wh): The larger variant ensures maximum range when tackling demanding elevation profiles.
Fully Removable: Both batteries are integrated into the frame and can be removed in just a few simple steps. This allows for flexible charging—either on the bike or externally—as well as safe and secure storage.
Tailored Cockpit: Kiox 300 or Purion 400
Depending on the model and intended use, two different Bosch displays are available to keep your riding data and system controls perfectly in view.
Bosch Kiox 300: A high-resolution color display featuring comprehensive data metrics and integrated navigation. Centrally positioned, it is ideal for touring riders.
Bosch Purion 400: A compact, minimalist color display securely tucked behind the handlebars. Reduced to the essentials, it is optimized for sporty trail riding.
Digital Theft Protection: Bosch ConnectModule
For added security, the ConnectModule is installed invisibly within the e-bike, enabling digital theft protection and GPS tracking via the Bosch Smart System.
eBike Alarm: After switching off the e-bike, the theft protection activates automatically. In the event of suspicious movement, the system triggers an acoustic alarm and sends a push notification to your smartphone.
GPS Tracking: Should the bicycle be stolen, the e-bike's precise location can be tracked via GPS signal directly within the eBike Flow app.
