Which cable to use with your bike?

The Bosch PowerMore cables, models BCH3923 and BCH3925, are designed to connect the PowerMore 250 battery to your e-bike, differing primarily in their cable routing direction and length options to accommodate various bike configurations.
Key Differences:
- Cable Routing Direction:

Selecting the Appropriate Cable:
- Assess Your Bike’s Layout:
- Identify the position of your e-bike’s charging socket relative to the battery holder.
- Choose BCH3923 if the socket is near the battery holder, requiring the cable to route towards it.
- Opt for BCH3925 if the socket is positioned away from the battery holder, necessitating the cable to route away.
- Determine the Required Length:
- Measure the distance between the PowerMore 250 battery and the charging socket to select a cable length that ensures a secure and tidy connection.
Selecting the correct cable model and length is crucial for optimal performance and a clean installation of your Bosch PowerMore 250 battery system.
