They are all good brands, although Schwinn is at the bottom of the list. The Giant Cypress bikes can be had in your price range, and are suitable for street and trail riding, but not anything real real rough. They are referred to as "comfort bikes." They aren't high performance, but they are comfortable and easy to ride. Spending a little more can get you on a flat bar road bike, or "hybrid" which will boost your performance, and are what is usually suggested more for fitness riding. That's about a $500 price point.
