Start with the Right Tools and a Clean Workspace
Taking a bicycle apart is straightforward if you have the correct tools and a place to work. You will need an adjustable wrench or a set of wrenches that fit your bike's bolts, a Phillips and flathead screwdriver, a hex key set (also called Allen wrenches), and a bike-specific tool called a crank puller if you plan to remove the pedals and crankset. A workbench, sturdy table, or even a clean floor works fine—just make sure you have room to lay out parts as you remove them.
Before you start, take a photo of your bike from the side with your phone. This reference image will help you remember how everything fits back together, especially cable routing and brake alignment. Lay out a clean cloth or newspaper to keep small bolts and screws organized by section—one pile for the drivetrain, one for the frame, one for the wheels. Losing a bolt means a trip back to the bike shop.
Key Takeaways
- Remove both wheels first by loosening the quick-release levers or axle nuts, then lift the chain off the rear sprocket before pulling the wheel free.
- Take off the pedals using a wrench or hex key, turning counterclockwise on the right pedal and clockwise on the left pedal because the threads are reversed.
- Disconnect the handlebars by unbolting the stem from the fork and the brake and gear cables from their anchor points on the frame.
- Separate the crankset and bottom bracket from the frame using a crank puller tool, which requires turning a handle to push the crank arm off the axle.
- Take photos before disconnecting cables and keep bolts organized by location so reassembly follows the reverse order.
Remove the Wheels in the Correct Order
Start by flipping the bike upside down so it rests on the handlebars and seat, or use a bike stand if you have one. This keeps the frame stable and gives you clear access to both wheels. For the front wheel, locate the quick-release lever on the left side of the hub (the center of the wheel). Open the lever by flipping it outward, then unscrew the bolt on the opposite side by hand or with a wrench until the wheel lifts free. If your bike has solid axle nuts instead of a quick-release, use a wrench to turn both nuts counterclockwise.
The rear wheel is slightly more involved because the chain sits on the smallest sprocket. Shift the chain to the smallest gear using the right shifter before you start. Open the quick-release lever or loosen the axle nuts the same way as the front, then pull the derailleur (the mechanism that moves the chain) backward with your hand to create slack. Lift the chain off the smallest sprocket and pull the wheel away from the frame. Keep the wheel upright as you set it down so the chain does not fall into the spokes.
Disconnect the Pedals and Crankset
The pedals come off with a wrench or hex key, but the threading is reversed on each side to prevent them from unscrewing while you ride. The right pedal (the one on the chain side) unscrews counterclockwise like a normal bolt. The left pedal unscrews clockwise—the opposite direction. Use a 15 mm wrench or a hex key that fits the pedal axle, and turn firmly; pedals are often tight. Once both pedals are off, set them aside in a safe place.
Removing the crankset (the two large chainrings and their arms) requires a crank puller tool, which you can rent from a bike shop if you do not own one. Insert the tool into the threaded hole on the back of the crank arm, then turn the handle clockwise. The tool pushes the crank arm off the axle. Repeat on the other side. Once both crank arms are free, the bottom bracket axle (the spindle that runs through the center) can be unbolted from the frame using the appropriate wrench or hex key, depending on your bike's model.
Disconnect Cables and Remove the Handlebars
Before you remove the handlebars, you must disconnect the brake and gear cables. Take a photo of how each cable runs along the frame so you can route them correctly later. Locate where each cable enters its housing (the plastic or metal tube it runs through). Loosen the bolt that clamps the cable to the brake or derailleur using a hex key or wrench, then pull the cable free. If the cable is crimped or frayed at the end, note that it will need to be replaced during reassembly.
With the cables disconnected, unbolt the stem (the part that connects the handlebars to the fork) by removing the bolts on the front and sides using a hex key. The front bolt holds the handlebars in place; the side bolts find the stem to the fork. Once these are loose, lift the handlebars and stem away as one unit. If your bike has a headset (the bearing assembly where the fork meets the frame), you may need to loosen the top cap bolt slightly, but do not remove it completely unless you are replacing the headset.
Separate the Fork and Frame
The fork (the two tubes that hold the front wheel) connects to the frame at the head tube using the headset bearing system. To remove the fork, you must first loosen the headset. Locate the large bolt on top of the head tube and turn it counterclockwise with a wrench until it is finger-tight—do not remove it completely. This releases pressure on the bearings. Next, unbolt the brake caliper (the part that squeezes the wheel rim) from the frame using a hex key, and set it aside carefully so the brake fluid does not leak.
Once the headset is loose and the brake is off, pull the fork straight up and away from the frame. The fork should slide out smoothly. If it sticks, wiggle it gently side to side rather than forcing it. Set the fork in a safe location where it will not get bent. At this point, you have separated the main frame from most of the major components, and the frame itself is ready for cleaning, storage, or transport.
Keep Track of Small Parts and Hardware
As you remove each section, place all bolts, screws, and small parts into labeled containers or bags. Write the location on each bag with a permanent marker—"headset bolts," "stem bolts," "brake caliper bolts." This prevents confusion during reassembly and ensures you do not lose critical hardware. Bolts of different lengths look similar but are not interchangeable; using the wrong bolt in the wrong hole can damage threads or cause parts to come loose while riding.
For cables and housings, coil them loosely and find them with a rubber band or zip tie so they do not tangle. If you are storing the bike for more than a few weeks, explore a light coat of oil to any exposed metal parts to prevent rust. Keep all your labeled bags and containers together in one box so nothing gets misplaced before you reassemble the bike.
Reassemble in Reverse Order
When you are ready to put the bike back together, work in the opposite sequence: fork and headset first, then handlebars and cables, then crankset and pedals, and finally the wheels. Tighten bolts firmly but do not over-tighten, which can strip threads or crack plastic components. Use your reference photo to confirm cable routing and brake alignment before you test-ride the bike. Spin each wheel by hand to make sure it does not rub against the brake pads or frame.
After reassembly, take the bike for a short, slow ride in a safe area before riding normally. Check that the brakes respond smoothly, the gears shift without grinding, and the wheels spin straight. If anything feels wrong, stop and double-check that all bolts are tight and cables are properly seated in their anchor points.
Frequently Asked Questions
Do I need special tools to take my bike apart?
A basic set of wrenches, hex keys, and screwdrivers will handle most of the work. A crank puller is necessary only if you are removing the crankset; you can rent one from a bike shop for a few dollars. Everything else uses standard tools you may already own.
What if I lose a bolt during disassembly?
Take a photo of the bolt or bring it to a bike shop to match the size and thread type. Most shops sell individual bolts cheaply. Do not reassemble without replacing it—a missing bolt can cause parts to shift or fall off while riding.
How do I remember which cables go where?
Take a photo of the bike before you disconnect anything, and label each cable with tape as you remove it. Write "front brake" or "rear derailleur" on the tape so you know exactly where each cable belongs during reassembly.
Can I take the bike apart without a workbench?
Yes. A clean floor, table, or even a blanket spread in your yard works fine. The key is having enough space to lay out parts and keep small bolts from rolling away. A bike stand makes the work easier but is not required.
How tight should I make the bolts when I put it back together?
Tighten bolts until they are snug and do not move, but stop before you feel strong resistance. Over-tightening can crack plastic parts or strip metal threads. If a bolt feels very tight before the part is fully seated, back off and check that the bolt is aligned correctly.
