Thanks for all the quick replies. Part of our delima has been solved. My wife rode a Terra Trike Rover today and told me this is the one I want. She sat on a couple others and even without riding them, she said the Terra Trike was the one. She did ride the Rover around the lot and decided with the bike shop making the adjustments for the fit, she is happy and we brought it home. Even with the 20" wheels and the 330 rear hub , which was explained as a CVT for a bike, it makes things less complicated for her and we will see how much rides.
I am still out to lunch, so to speak. I don't want to give up my Speicalized Roubaix for a trike just yet. Gonna wait and see what happens and how hard it is for us to ride sort of together. A trike is in the future, I am sure. Just need to make up my mind which one.
