SOURCE: how to adjust front and rear shifting gear
You have to screw the cable adjuster all the way in for starters. Then you pull the derauiler all the out to the largest sprocket nearest the spokes and tighten the cable down here. Now there are 2 adjusting screws that limit the travel and adjust these ever so slighty as a little goes a long ways. Shift therough the gears with the bike inverted is the best method while doing all of this. You will be able to make the adjustment so the derauiler goes from the largest to smallest sprocket by these 2 screws if done properly. you may eventually have to tighten the cable adjuster also in some cases for proper travel.
Better off if you let a shop do this if you go tofar you can throw the derauiler into the spokes and mess everythign up BIGTIME for the few $$'s it amy cost ya. GOOD LUCK

im certain that model has a 3 piece crank set up. the inner crank bearing jam nut has loosened up or the bearings themselves have gone bad.first check to see if its tight, if it is then it will require a replacement set of bearing that are a pretty standard size to all bikes and can be purchased at nearly every bike shop.

If you bought it last night then you should be able to take it back. Take the receipt with you. Do NOT attempt to fix it yourself since you just bought it less than 30 days ago. Just exchange it or return it for refund.
