Need extra cable length between your hub motor and controller?

Bafang uses different connectors across different motor and wiring systems.
Before purchasing, please compare your existing connector with the product photos.

90 cm or 150 cm—Which Length Should You Choose?

steering or other moving parts where applicable.
Installation Tips
Turn off the e-bike and disconnect the battery before installation.
Check the alignment mark on the connector, align both sides carefully and push
the connectors together straight.
Do not force or twist the connector if the pins do not line up.
A connector that looks similar may still use a different keying or pin arrangement.
After connection, secure the cable along the bike frame and keep it away from
the chain, brake rotor, tire and other moving components.
Which 9-Pin Motor Cable Do You Need?

Frequently Asked Questions
Is this cable compatible with every Bafang motor?
No. Bafang products use different wiring systems and connector types.
Please confirm that your existing hub-motor connection has the same 9-pin
connector shape and pin arrangement shown in our product photos.
Can I use this cable with a Bafang BBS01, BBS02 or BBSHD system?
Do not order this cable based only on the Bafang brand name.
This product is intended as a hub-motor extension cable.
If you use a Bafang mid-drive system, please compare your actual connector
or contact us with photos before ordering.
What is the difference between the 90 cm and 150 cm versions?
The connector type is the same; the difference is cable length.
Choose the version that best matches the routing distance on your e-bike.
What should I do if I am not sure whether my connector matches?
Please send us a clear close-up photo of the motor connector and controller connector.
We recommend confirming compatibility before placing the order rather than relying
only on the number of pins.
