What spot on bikes will end up being “standard” for e-bikes? I watched reviews and some reviews and some have it in the bottom bracket of the frame, while others have it in the rear hub. There are some fairly obvious advantages and disadvantaged to both placements. I am curious, are there any e-bikes with the motor in the front hub? That could make sense for ease of replacement or repair.

Also, is it likely e-bikes will get lighter over time? So many I see on the roads here are really heavy.
