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*.

KMC e9 chains hold up really well on an ebike with a 190Nm/1700W motor, in my experience of trying a few.
What's the motor?
I've used KMC X11e/e11 ever since this disaster. No broken chains and they last very long on non-ebikes too.
