If you don't know the BLE communication protocol of your bike's battery BMS, there's no point in trying to improvise!
I have experience in discovering BLE communication protocols.
My suggestion:
If there is an app (Android) to access the Battery BMS, there is a process to capture this protocol.
Bluetooth hci snoop log - capture BLE communication:

With the captured log files, you can analyze and study the entire BLE protocol with Wireshark.

Interesting BLE tool:

nRF Connect for Mobile:

BLE Scanner

You will also need to study the BMS protocol. Probably smbus.

If you have any questions, ask me. Good luck.
