What kind of Bicycle Tools do you need? The most important tools are:
Cone Wrench
A cone wrench is used to access flats on axles where very little of the axle is exposed, similar to an open-ended wrench but much thinner, about 2 mm thick, compared to approximately 15 mm for a standard open-ended wrench.
Tire Levers
Tire levers are used to remove a tyre from the rim. This has to be done when you change the inner tube. If you use a plastic lever it might break and a metal lever might damage the tube.So keep this in mind when you use them.
Pry the edge of a tyre away from the rim of the wheel. Use one iron to pry a portion of the tyre from its wheel and hold it in position. Then use the second iron further along the tyre to pry more of it away from the wheel. Separate the tyreand remove the first iron and use it again on the far side of the other iron. Work your way around the tyre to fully remove it from the wheel then you can reach the tube that sits inside.
If you don't have these tools then you can use other tools like screwdrivers etc. to achieve the same purpose.
