Painting a bicycle is a great way to save money and give your bike a brand-new look. You can choose to paint your bike without taking it apart or disassemble it for a more thorough paint job. If you decide to take your bike apart, you will need basic hand tools such as wrenches and screwdrivers. You will also need to remove the seat, shifters, cables, wheels, cranks, bottom bracket, derailleurs, chain, brakes, handlebars, and front forks. It is important to keep the screws and small parts in labelled bags to make reassembly easier. Once disassembled, you can begin the painting process by lightly sanding the parts you want to paint and applying primer. After the primer has dried, you can start painting with your chosen colour, using thin and even coats for the best results.

What You'll Learn
Removing the wheels, cranks, bottom bracket, derailleurs, chain, and brakes
To begin taking apart your bike, you'll need some basic hand tools, such as wrenches and screwdrivers, to disassemble the various components. You'll also want to have some ziplock bags to store screws and intricate parts, and take photos of the bike before disassembly for reference when putting everything back together.
Removing the wheels
To remove the wheels, first release your brakes. If your bike has rim brakes or cantilever brakes, release the cable tension to remove the front wheel. For rim brakes, there should be a lever near the caliper that will release some cable tension, allowing the brake pads to move away from the rim. Next, open the quick-release or remove the axle. If your bike has a quick-release, flip the lever into the open position and, if tight, use a tire lever to pry it open. For thru axles, open the lever and turn it counter-clockwise to unthread the axle and remove it from the hub. Now, lift the wheel up and out of the fork, being careful not to dislodge the calipers if you have rim brakes or damage rotors if you have disc brakes.
Removing the cranks and bottom bracket
To remove the cranks, start by removing both left and right crank arms. Then, inspect the threaded cups for tool fittings and insert the appropriate tool. For the non-drive (left) side, turn the tool counter-clockwise while holding it firmly to the cup, and then remove the drive (right) side cup by turning it clockwise. Finally, remove any internal sleeves and spacers, taking note of their positions for reassembly.
Removing the derailleurs, chain, and brakes
While not mentioned explicitly, it is likely that you will need to remove the derailleurs, chain, and brakes in order to fully disassemble the bike for painting. This may involve releasing cable tension, removing bolts, and carefully detaching components. Refer to your specific bike model's documentation or seek online resources for detailed instructions on removing these parts.

Taking off the handlebars and seat
To start taking your bike apart to paint it, you'll need some basic tools like wrenches and screwdrivers. You'll also need a clean and well-ventilated workspace. It's a good idea to take photos of the bike before you begin so you can refer to them when reassembling everything.
First, remove the bar tape from the handlebars. Next, loosen the brake mounting screws and slide the brakes off the bars. Now, undo the four fasteners on the faceplate of the stem, and the handlebars will come off. If the bolts are rusted, try using penetrating oil or oxalic acid to help loosen them. If the bolts are particularly stubborn, you may need to use an impact driver or carefully grind away the head of the bolt and knock the remaining stem with a punch.
To remove the seat, you'll need to loosen the bolts on either side of the saddle with a wrench. Depending on the type of bolts you have, you may need an opposing wrench on the other side. Loosen each side by half a turn, and you should be able to slide the seat off the post.
Once the handlebars and seat are removed, you can continue disassembling the rest of the bike, including the wheels, cranks, bottom bracket, derailleurs, chain, brakes, and front forks. Don't forget to remove any accessories like a water bottle holder, and place all screws and small parts in labelled bags so they're easy to find when it's time to reassemble your bike.

Dismantling the frame
To start, remove the seat, shifters, cables, and other parts that will not be painted. You can use basic hand tools such as wrenches and screwdrivers for this step. It is a good idea to put small screws and parts in labelled ziplock bags so that they don't get lost and to take photos of intricate parts for reference when reassembling.
Next, remove the handlebars, front fork, and seat post. You can then take off any old decals, badges, or decorations using a razor blade. Warming them up with a blow dryer or heat gun first will help to loosen the adhesive.
Once the frame is bare, you can prepare it for painting by lightly sanding the areas to be painted to remove any rust or old paint. Wipe down the sanded areas with a wet cloth to remove any dust or paint fragments and let it dry.

Sanding and priming the parts to be painted
Before you begin sanding, it is important to disassemble your bike until you are 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. You should also remove any labels or decals from the bike frame. If they are old and stuck on, use a blow dryer or heat gun to warm them up and loosen the adhesive.
Once your bike is in pieces, lightly sand the parts you want to paint. If your bike has a lot of rust, you will need to use a power sander or rust remover before painting. You can use sandpaper with grits ranging from 400 to 800. Sanding gives the surface grip so that your fresh coat of paint sticks better and lasts longer. After sanding, use a wet cloth to wipe down each piece to remove dust and paint fragments, and then let the parts dry.
Next, you will need to apply a primer. Make sure to follow the manufacturer's instructions and allow sufficient time for the primer to dry. For instance, one source recommends applying three thin coats of primer spray paint, allowing 10 minutes of dry time between each coat, and then letting it dry overnight.
Once the primer is dry, you can start applying the colour. If you are going for a two-tone paint job, decide which colour will go on first; light colours should be applied first. After applying the first colour, let it dry, and then mask off for the second colour. Once the colour coats have dried, you can clear coat the bicycle if you like. As before, read the directions on the can and apply 2 to 3 coats of clear.

Painting and clear coating
Painting a bicycle is a great way to give it a brand-new, glossy look. You can paint your bike without taking it apart, but for a full paint job, it is recommended to disassemble it. If you do decide to take it apart, you will need basic hand tools such as wrenches and screwdrivers.
Once you have disassembled the bike, lightly sand the parts you want to paint. If there is rust, you will need to use a power sander or rust remover. Then, wipe down each piece with a wet cloth to remove dust and paint fragments and let it dry. Next, apply a few thin coats of primer spray paint, allowing sufficient drying time between each coat and letting it dry overnight to set.
After the primer is dry, you can start applying the colour. If you are going for a two-tone paint job, start with the lighter colour first. Once the first colour is dry, mask off for the second colour and spray. After the colour coats have dried, you can apply the clear coat. Read the directions on the can and apply 2 to 3 coats of clear.
If you would prefer not to disassemble your bike, you can still paint it by following a careful, step-by-step process. First, clean every inch of the bike, using a degreaser such as WD-40 or a citrus-based option. Then, sand the frame lightly with sandpaper to give the paint better grip. Next, mask off the parts you don't want to paint, such as brakes, gears, and tires, using painter's tape and plastic bags. Then, spray on the primer, let it dry, and then use smooth, even strokes with your chosen colour. Once dry, peel off the tape.

The bike should be disassembled until only the frame remains. This includes removing the wheels, cranks, bottom bracket, derailleurs, chain, brakes, handlebars, seat, and front forks. Any accessories or attachments, such as water bottle holders, should also be removed.
Use sandpaper to lightly sand the parts of the bike you want to paint. This will help remove rust and scuff up the old paint. A razor blade can be useful for removing old decals and decorations. After sanding, wipe down the parts with a wet cloth to remove any dust or paint fragments before applying primer.
