My mother is looking for a new bike (to replace a really old one) She is barely 100lbs and something like 5'2" Definately a petite, my 11 year old sister is almost as tall as her. She has basic female preportions, long legs and a shorter torso, but I do not know her actual measurements to really get into sizing just yet.

Being an averaged sized male rider, I'm sort of in the dark as what to look for in a bike for a woman. Who makes a good one? Looking for something comfortable all day, but definitely wants to be able to keep up.

Was looking at things like the Trek 2000, are these "WSD" bikes any good? or should we think something more along the lines of Terry?

any help is appreciated, thanks
