How to identify Bosch motor?

[danfoto]

I have a new 2023-model ebike which has a Bosch Performance Line motor rated at 75Nm torque. Seeing as how the maker's bumph doesn't tell me and there seems to be no label on the motor, how can I tell if it's a BDU450CX or a BDU490P?

the smart motors use a different shape speed sensor on the new motors.

Indeed they do. But as you may see from my post above, what I need to know is the type number of my motor.

i have the ebike connect app but when i click on my motor the part number says unknown as i have the old gen 2 cx motor.

a dealer should be able to tell you what it is if they have the bosch software.

Maybe the e bike flow app thingy will tell me. I'll install it and have a go - if I can get my head round it ...

just make sure Bluetooth is turned on and download the app you can also link it to kommoot stravia ect.
