Mongoose is the run of the mill brand on the utilitarian side. They are a perfect step for a kid or an adult getting into biking. All aluminum is great because it is so light weight but that is pretty much the normal material for bikes these days. If you become a serious biker you will find out what you do and do not need by riding a Mongoose.

It should say on the side of the tire "Inflate to -- psi" I would say in the 35-50 psi range.

do u know the brand of the bike?

The master link has an elongated clip on one side of the link. You have to look carefully at every link until you find it. The clip will only be on one side of the chain, so you may have to look at both sides. Put a dot of white paint on one side of the chain so you know when you have looked at the entire length of chain before looking on the other side. If you're lucky, you should find it rather quickly.

replace the cable.

replace the hub with a new one. It requires a special tool that can be obtained by purchasing one online and is cheaper than having a bike shop replace it.

tools needed adjustable wrench, 10mm wrench or 6mm allen wrench. Loosen the fastener on the back of the brake pad. remove it then replace with a new one. Making sure that as you tighten the fastener back you are holding the working surface of the brake pad on the side of the wheel. Pay close attention that the brake pad doesn't touch the tire when the lever is pulled.

change the shifter to the smallest gear, pedal while you shift. Once you get it there check the tightness of the cable that is going to it. If it is loose get a 9 mm combination wrench, loosen the clamp located on the front derailleur at the end of the cable. Pull the cable through the clamp and make the cable tight then tighten down the clamp with your wrench. This should make it go up to the biggest gear now. If it doesn't play with the screws, they are travel limiters.
