I'm going to have to find my way to that trail looks very nice!That's amazing how you knew it was that trail just from a few close-up bike pictures! And you live in Arizona too. That is a beautiful paved trail as you know, 21 miles of almost isolation, at the end, in Vernonia Oregon there is a downtown with more than a handful of cafes to sit down for lunch.
With the pedal assist, we commented that we didn't even notice the long grades or switchbacks until we were going downhill and almost inadvertently notice that we don't have to pedal anymore.
I think there are a lot of racks that will fit the Como, just deciding on getting the bike seems like a big enough decision for the time being. The first rack that I bought was a dumb purchase, It was heavy, expensive and obstructed the red light under the seat. I've since shelved it. The top half of that rack is in my avatar picture, it's mounted on the Roll rack.
Please keep us posted on what sounds like your impending purchase!
