Designed by Bosch eBike Systems, this genuine cable offers proven durability and extensive compatibility with the Active Line, Performance Line, and Performance Line CX motor ranges (BDU2XX, BDU3XX, BDU4XX).

Technical Overview

This connection cable with a length of 310 mm is specifically developed for PowerTube 500 Wh and 625 Wh frame-mounted batteries. It ensures the transfer of energy and CAN data between the battery and the eBike system, enabling the display to manage assistance and communicate with all electronic components. Its robust design withstands the mechanical stresses and vibrations encountered on demanding terrain.

Technical Highlights

• Precise 310 mm length: Optimized for PowerTube downtube installations, it enables discreet and efficient cable routing within the frame.
