the 25" 7200 is a little big at 6'2 but i like it the best for the riding you say you will be doing. If you can get him to come down $50 that is the one i would do. You can always switch out the stem for $15-$20 to make it fit better if need be. You are headed in the right direction, stay away from the wally world bikes. All will work, but you will ride which ever you think looks the best. Make sure you will be proud of it and then ride the crap out of it.
