Bafang replacement Display for Carrera Vulcan (in frame battery)

[CueBall]

Hi,

My first post here, so be gentle lol.

I am trying to replace the display on my sons 2024 Carrera Vulcan E (water ingress and wont turn on now). It is a newer model with the Bafang battery integrated into the frame.

Battery is fine, I get 42v on the pins at the battery and the again on two of the pins at the display connector, it just won't turn on when pressing the button on the display now, assume given the water ingress.

It has a Bafang G020, 250w rear hub motor and the display has a semi-triangular connector. The display has DP C221 CAN 1.0 written on the back - Which I assume means it's on a CAN protocol.

The trouble is all the displays I see online seem to relate to mid-drive motors, not hub motors and I don't think the two are compatible.

Any assistance would be appreciated.

You've told us everything except which display it is.

Thanks for the reply. As per original post, the display has DP C221 CAN 1.0 written on the back (and Bafang logo on the front).

The advertisers may just be listing those motors it's more commonly used with rather than showing everything it's compatible with. Bafang themselves don't seem to limit this display only to their mid-drive motors. You could email them and ask. But the first thing to do would be to fully dry out the one you already have and try it again.

If you take a look at the pics in this link... They specifically place a cross through the hub motor and tick the mid-motor. Which is what is concerning me...

If you look at the reviews, the first one is from UK and says, "Works with my Bafang rear motor".

Ah-ha... Would be useful if I had checked that... Thank you... Will give that one a go, as least I can return Amazon items easily.
