gear and chain wear from motor strain on 1500w Prime

Love the bike so far, now that I got a mechanic to bleed the rear brakes.

How are the gears and chain holding up for veteran riders?

I'm curious to know what kind of life I should expect out of those components since there is superhuman stress loaded onto those components.

Or if there is any advice, from the forum or Nireeka on how to preserve the longevity of those components.
