Exciting news! Even though Ride1UP and Eggrider could not confirm compatibility with the Roadster, and I got conflicting information, I took a risk and ordered and EggRider Lishui version LCD replacement from https://eggrider.com/
It took a lot of trial and error, and messing around, but I think I got it working! LCD display seems brighter and readable with my polarized sunglasses, and the display has more data and is customizable via Bluetooth with an Eggrider app (in my case, the Android app). Need to do a bit more testing to validate accuracy, but for me it's worth it if just for a more visible display.
Notes:
I have a mid-2021 Roadster v2.
I ordered from Eggrider the Lishui variant
Had to do a wire transfer, and get it shipped from the UK
Took a couple of weeks to arrive
After receiving, set up via Android app, as a Bafang controller, changed default 9 PAS levels to 5 PAS levels
Verified or set up EggRider Display and Bafang settings, 36 v, nominal current 7a, limit current 15a, undervoltage 31 volts, battery range 41.8 v to 33.8 v (?), max speed assist 39 km/h
No guarantee if it'll work for you, but I'm happy to have gotten it pending final testing!
