Thanks that seems pretty good for an ebike chain. I snappedmine in less mileageI use a Wipperman chain, I have better experience with it than KMC. But I don't use e-bike specific chains, just the entry level 7-8 speed chain which so far has worked just fine. At >3600 km and two or three shots of chain lube during that time it doesn't like extreme chain angles any more and has dropped down to the small chainwheel a couple of times recently.
