Looking to try/buy some bikes at the Seattle Bike Expo this weekend. I am 54, female, pretty fit, but w/some neck and wrist problems (hills have always been hard for me too); so reading the thread on Townies was helpful. Any info/advice for a new bike would be great. Have even considered electric assists, but I guess I am not that wimpy yet. Have been an occasional rider for several yrs. on bike paths in the area and our many RV trips.
