Hey guys I bought a used XR last year and I have done absolutely nothing to it other than charge it. I really don't have much knowledge about the device other than how to ride it and at this point I'm almost afraid to ask... Do I need to be doing maintenance on this?

My XR, Smitty Warbenjagermanjensen, is an absolute beast, some would call him #1 and I want to make sure he's gonna last. He's definitely seen better days, he got ran over by a van months ago but still functions fine, it's never randomly shut off on me like I see so many people complaining about.

But what general maintenance should I be doing? I'm gonna need to replace my wheel pretty soon so might as well do some other stuff if it needs it.
