Ancheer controller brand

[texas dave]

I have a 2019 ancheer 350 watt bike and want to replace the loop speed display with one that is more comprehensive. Does anybody know who builds the controller for ancheer so I can match with the proper display....or will any aftermarket with matching plug work
Thanks, dave

Mine current display is a led....I am trying to figure out the speed controller brand so I can match up a lcd display.
