The motor assistance feature looks interesting. Aren't bikes supposed to be light? I would guess that the benefit of having a motor and batteries that can provide worthwhile assistance would be counteracted by the fact that there's that much more weight to move around all the time.
Bikes don't need to be light, the bike + rider combo needs to be light. If you are 200 pounds, the difference between a 20 pound and 30 pound bike is a rounding error.
Anecdote: I don't notice much change in bike handling even when I have 40 pounds of groceries on the back. I do notice the difference between my 22-pound utility bike and 18-pound racing bike, though. Not because of the weight, but because of the very different geometry. (I think this is why people think light bikes are fast - racing bikes do feel faster. But it's not their weight, it's the very tight geometry that would be unsuitable for a touring bike.)
