This is an Ultegra 11s chain after 1000km of wear from a 1500W mid-drive. Used to ride a Tangent back in 2016. T'was shredding till it went *clunk*.

Is it me or the chain is just poorly maintained that it might actually be grinding out for about 600km or so? I doubt the motor is outputting 1500w all the time so it's likely the wear isn't from the overly powerful motor, but lack of lube. GCN released a video a week or so ago about degreasing chain, and yours look just like theirs lol.
That motor was outputting 1500W at every start from a dead stop and often for extended periods during cruising. That motor was actually 3KW but I had it limited due to the max battery current and the insufficient size of my balls. That said I'm pretty sure grinding was a major contributor too. :D
The very first time I rode this, I hadn't limited the power, I pressed the throttle and the bike escaped from under me by doing a violent wheelie.
