I too prefer the Brammo style...which is why I haven't really planned on buying a Zero...still I do like the improvements they are making. And two person riding is a nice addition. Even though I rarely ride 2 up, it is something I will miss with the Enertia Plus.
But I will wait a bit longer as I like the Enertia more than the Zero bikes....
That said, once you go electric for commuting it is hard to go back. I'll keep my gasser for my long trips (which are only a few times a year), but I don't use it at all anymore as my daily rider.
Still, God forbid, if something goes south with Brammo I will be looking a lot harder at those Zero bikes.
At this point I NEED** an electric bike...

**I don't really NEED one, but I won't buy another gas bike...which is tough as there is a beautiful Kawasaki "Bonneville" clone up on Craigslist....and I still think the Bonneville is the most beautiful bike ever made...
