Assuming the belt holds up. A motorbike style o-ring chain would be better.Lost me at cvt lol. But I would have thought that one of the first things to go with a decent mid drive ebike would be the derailleur. Single pivots are the other thing that I would think match an ebike well. When you have more power, you don't really care for pedal bob. It also allows you to run a carbon belt making the back end much cleaner and ditching any sort of tensioning all together.
