I should really let this go but you are massively misstating the difference 10 or 20 pounds of ebike equipment. Weight really only matters when accelerating or going up hill. Cruising at a constant speed it doesn't matter. The heavier bikes ride fine, I typically get half way through my rides before I feel the need to turn on the assist. touring bikes can go as high as 80# with gear people ride those through flipping mountain ranges all the time.

Half of you guys are saying the same thing I am: only way to reduce weight is to reduce capacity. My point to the OP is you may THINK you want to prioritize weight over everything else, but my contribution to you is you may rethink that once you gain some experience on an ebike. The lighter weight bike really isn't going to ride that much better, but make too many compromises on battery size and you are going to be left with a bike that doesn't do anything well.
