I have a Trek hybrid (a 7200 - a little higher than your preferred price range) that I am very happy with.
i have a Trek 3700 and it's a hair over 400.00.i painted my sons bedroom for it and i do have to admit, it is a nice bike and i would recommend it to you for her.some advice to you too.she will probably like the riding thing,so you may want to get a slightly "nicer" bike for her.that way,later down the line you wont have to!! ride onHey everyone, I'm trying to get my girlfriend into biking. What's a good starter bike for her? We are trying to keep it under 300$.
