and the brake levers need to be disc compatible too, so they and the grips will need to be swapped out... and the freewheel on your bike will not work with the rear FREEHUB... i've never seen a disc type, freewheel type, hub...
save up and buy a better bike.... with real suspension instead of glorified pogo sticks.
did your bike come with the stamped steel or aluminum brake arms? if aluminum, upgrading to Koolstop pads will substantially improve the brakes... Better cable housings and levers will help too...
