Your husband and I are similar in size and I started out on a Fuji hybrid. (Absolute 4.0) It was a sturdy frame and solid wheels. I still use it for commuting, it's so tuff I think I could hit a Honda head on and keep going.
Soreness solved! I expected to be sore and have to adjust to biking, esp. the seat, and maybe need some bike shorts, but did not expect the the rubbed raw skin. After trying some adjustments, I gave in and bought a new seat. I rode 4 miles today with little pain. THIS level of pain is what I anticipated as I adjusted to biking. I don't mind some pain, but the other seat was just awful and not for me.
