Hey Kelda,
I'd check out the Yuba Spicy Curry. They've upgraded to a Bosch motor this year and we've been loving it. They allow for some extra carrying room in the back as well in comparison to the Juiced Models. They other bike (trike, technically) you might want to consider is an IZIP E3 Go...
We've been loving the Wave frame models from Bulls. Check out the Bulls Cross Lite E and the Bulls Lacuba Evo E8. Super easy to mount and dismount and very much in the upright position. Go for the Lacuba if you're looking for the longest battery life. Brose batteries go forever.
