You really don't need, nor should you want full suspension if you are going to be riding primarily in the city. Suspension has no real use on paved roads and mild trails. All it really does is add weight, adds expense and something to be maintained and/or repaired, and makes you pedal harder for reduced output. When you are riding a full suspension bike, each time that you go through the power stroke of your pedalling motion, you are slightly compressing the suspension which uses some of the force that you would normally be transmitting to the drive wheel. In addition, the suspension cylinders have to be recharged with oil or air, and all of the linkages have to be cleaned and lubricated several times a year. Plus all of the extra components can add up to ten extra pounds of weight. Unless you plan upon riding some really rugged trails, you should stay away from full suspension. A lot of people get a suspension fork when they get a comfort bike and they are a little more acceptable, at least they aren't reducing your pedalling force but they still add weight and expense. I have always thought that a good suspended seatpost is the best suspension for city riding. It is light and simple and protects you from the minor bumps that you will encounter in town as well as a more extensive suspension will.
