Litos, those are both good, simple, albeit heavy and a bit ponderous rides. The cruiser is great if you're only going a short distance and don't have any/many hills.
Something with a few gears might be an easier starting point and could get ridden more often. Something like this, but there are a million choices at or a little below this price point.
