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

SOURCE: My son purchased a mongoose 24

Any good bicycle repair shop should stock a variety of wheels. Ask the staff and tell them what kind of riding your son does or better yet, take him along with you. A fun project if you can afford it is to build your own. Here is links to sites with good info:http://www.parktool.com/repair/byregion.asp?catid=56 and http://sheldonbrown.com/wheelbuild.html Hope this helps.

SOURCE: I want to raise the handle bars on my Mongoose

Be careful, the stem must be inserted at least 3" or to the safety line, or it will snap off. You have to have a metric allen wrench. Like I say, and I cannot stress it more, do not raise beyond the safety line on stem, buy a longer stem, if you want it higher than that. If, the bike is too small, buy a bike that fits you from a shop who specializes in sizing.

SOURCE: freewheel spins both ways cant peddle no were how

The freewheel has a ratchet pawl (an internal, spring loaded lever) that would normally engage gear teeth in one direction and click over them in the other direction. This is just like the action of a ratchet wrench. You might have a broken spring or broken pawl - in which case you will have to replace the freewheel---- Or it might just be dirty. Spray some WD 40 inside it (spray through the small gap between the round part that moves and the round part that doesn't. If that doesn't work, you'll have to replace it.
