Electric assist bicycles

This is pretty cool - self contained hub motor/battery/controller and a wireless accelerator lever:

This might be awesome on velomobile, as well.

That's a great idea. Plug and play. I'm not seeing much room for a battery pack though. They say 25 miles but I wonder what the rating is.

I'm really not into hub motors b/c they don't allow you to shift (the motor). With my setup it has the advantage of allowing you to shift the gear ratio the motor sees. A hub motor cannot do this. This severely limits at least one aspect of all electric riding (either takeoff acceleration, hill climbing or top speed). I know hub motors look nicer and provide good assist but I guess that's just my personal preference.
