PowerMore cable, cable routing towards the battery holder
Original Bosch PowerMore connection cable for connecting the PowerMore 250 Wh battery to electric bikes with Bosch Smart System. The cable routing towards the battery holder ensures correct and clean installation according to the frame geometry.
The PowerMore cable, cable routing towards the battery holder (catalogue designation BCH3923) is the original Bosch connection cable for the Bosch Smart System.
Main functions and applications
- Used to connect the Bosch PowerMore 250 Wh additional battery (Range Extender) to the charging/end connector in the frame of the electric bike.
- The cable is designed so that the cable routing is directed towards the battery holder (towards the frame / battery holder). This direction is important for proper installation according to the specific frame type and PowerMore mount location.
- There is also a reverse option(BCH3925 - cable routing away from the battery holder).
Available lengths
- 50 mm
- 100 mm
- 150 mm
- 200 mm
- 250 mm
- 300 mm

When ordering, it is necessary to choose the correct length according to the frame geometry so that the cable fits nicely, does not drag and is not too loose.
Compatibility
- Bosch PowerMore 250 Wh (additional battery)
- Bosch Smart System (PowerTube 625 / 750 / 800 Wh and later generation Bosch motors)
- Compatible with electric bikes that have a PowerMore mounting bracket (usually for bottle grips)
Key Features
- High quality Bosch connectors for reliable and safe power transfer
- Durable design suitable for outdoor use
- Easy installation (plug & play)
- Important addition when installing a PowerMore battery attachment - wrong direction or cable length can cause problems with fit or installation aesthetics
Note: When selecting a cable, it is always best to check with your specific bike model (or service center) to see which direction and length is recommended by the manufacturer. Some frames require a cable "to the bottom bracket", others "from the bottom bracket".
