1) My bike has stirrups (aka clips) and I really like them. They aren't as complicated as clipless pedals but they do help give you a little more leverage and they actually make me feel more secure when I am riding.

2) For the hills, anticipate them. Shift into an easier gear before you get there (my buddy is constantly reminding me of this as sometimes I end up riding my bike like it is a one speed). This way you won't have to get out of the saddle. Just take it slow and steady. I haven't encountered any huge hills, but I haven't had to stand up yet. Try asking your hubby to help you find some very flat routes until your legs are a little stronger.

3) My butt was my biggest problem (see "SORE BUTT" post). Do you have padded shorts? That helped a lot.

Good luck
