How much is this mountain bike going to cost me? That depends on how you answered the questions in Part 2 of "Your First Bike". If you decided on a non suspension bike then you'll be lighting your wallet by $350 to $650. If you have your eye on a front suspension bike with nice equipment package you will have to part with $600 to $1000. Tell the truth you really want a full suspension bike. In that case its time to reach deep into your riding shorts because you'll being putting out $900 to $4000. Keep in mind that prices I mention here are the start to about middle range of the price scale. You can spend a lot more if you like. Don't run out to the Bicycle Shop yet. Some of your friends may advise you that you can save a few dollar on a front suspension bike by buying a higher grade non suspension bike and upgrading by replacing the front fork and head set with suspension components. Don't try this unless you speak to the frame manufacturer. Every frame is designed to have its own geometry. The frames geometry determines the handling characteristics of the bike. Change the front fork ride height and you've changed the handling characteristics that were engineered design in by the manufacturer. There is better way to save a few dollars with mountain or road bikes. Opt for the higher quality frame with the lesser component package. Yes the bike will weigh a little more but you can always upgrade the components as they wear out or get damaged. FYI, Road bikes can range from $450 to as much as you'll pay.
A word about frame sizing.
A road frame should be sized at about 10" less than your inseam. Mountain bike frames require about 13" less than your inseam. I.e., A 33" inseam equals a frame no greater then 20", a slightly smaller frame won't hurt in mountain biking.
