This is a good cassette, but it's not strong enough for ebikes. The smallest cogs will wear out in less than a couple hundred miles with an ebike. I recommend the M8100 which is a little bit stronger, but will still wear out prematurely. Shimano is releasing an ebike specific drive train soon, whenever their manufacturing plant reopens after the "pandemic". But for that you'll have to buy an all new shifter, derailleur, cassette AND drive hub since it doesn't use a micro spline freehub. Money. That's all Shimano really cares about. Your money.
