I have a Raleigh c500 and that is a great bike for both trail and road for begining...I bought it this spring and now need a better road bike but since I do both every week I will have a specific trail and a roadie. Also for going around town I like it..
I dont know about your height as I am 5'10" but I know there are 3 or 4 sizes and I have the tallest. It really is a great duel bike for the begining and the tires are halfway- not big but not the thinnest so you get use to the preasurized tires...
