until you’re left with just the frame. Remove both wheels, the left and right cranks, the bottom bracket, the front and rear derailleurs, the chain, the brakes, the handlebars, the seat, and the front forks. If you have any attachments on your bike, like a water bottle holder, take the screws off from those too. Put the screws and tiny parts from the bike in labeled plastic baggies so it’s easier to reassemble it later. You might have a hard time taking them off if they’re old and really stuck on there. If they won’t peel off, use a blow dryer or heat gun to warm them up. The adhesive on the labels will loosen when it’s warmed, making it easier to remove the labels from the frame. If you’re having trouble peeling a label off with your fingers, use a putty knife to lift the edges of the label up off the frame. If there’s any glue residue left over from the decals, spray a product like WD-40 on the frame and wipe off the residue with a cloth. If the frame has a thick or glossy paint on it, use a low-grit (rough) sandpaper to remove a lot of the old paint. If the frame has a matte paint on it or it’s completely bare, use a high-grit (fine) sandpaper. Use a cloth with soapy water. There are a few parts of the frame that should be left paint-free:  The posts for the brakes. Any bearing surfaces. Any threads on the bike where something will need to be screwed in when you reassemble it.

How would you rephrase that briefly using Indonesian?
