Based on everything I've read thus far, I am pretty sure RPB uses rebranded off-the-shelf electrical products. I know the display is a Kingmeter SW-LCD-U, but for the life of me I can NOT find any info on what the OEM motor controller is. Does anyone know? Thanks in advance!

PS Just going to throw this here since I get this response to every question: I am not looking to upgrade anything. I know you can swap out the controller for aftermarket components. That's not what I'm after 

Dead Display on city ST3

I'm unable to use my bike's electrical system because I cannot boot the display (it got waterlogged and I believe something shorted/corroded).

Rad's website has the LCD upgrade for the runner and mission, but those only have 4 PAS levels. I think I would be fine with losing a level if that's what that means, but I'm not really sure how compatible those are with other models.

I also found this display:

which is clearly modeled after the rad display, but it doesn't explicitly claim to be compatible and has no written reviews.

Has anyone else gone through this process of getting a replacement display? Has anyone tried either of the displays I've mentioned on a 5-PAS-level model?
