When I've looked at the power and energy requirements of vehicles it seems to follow some sort of log(size) law when it comes to speed and energy per mass distance. But not for acceleration which is linear.

What that means is a small vehicle like a motorcycle needs more energy and hp per lb than a car to have the same range.

So could see higher performance batteries being very useful for motorcycles. Have heard noises that electric motorcycles and bicycles are heavy feeling. So lighter probably would be considered better.
