I bought my wife a Bianchi Milano for Christmas. It is beautiful, and rides really comfortably, and she is really happy. Unfortunately, we started going for longer (20 miles) rides together and found a fatal flaw for us. It really has no gear for climbing more than a really moderate slope. I live in Marin (SF Bay Area) and there are hills everywhere.
I don't want to get rid of the bike, and I am considering either replacing the rear wheel with a cluster that has a climbing gear and hanging a traditional rear derailler, or replacing the crank with a double and installing a front derailler.
Both of these may be terrible ideas, and I count on you very smart people to let me know.
It currently has a Nexus Alfine 8 sp rear hub and a 44T front sprocket.
