If you ride a bike regularly, you know that bike maintenance is vital to ensure the longevity and smooth performance of your bike. One of the most common, yet essential, maintenance tasks is removing and replacing a bike chain.
Whether you want to replace a worn chain, upgrade your bike, give your chain a thorough cleaning, or simply need your chain adjusted for a better fit, learning how to properly remove a bike chain can save you time, money, and frustration.
In this article, we’ll walk you through everything you need to know to easily remove a bike chain, focusing on the tools needed, step-by-step instructions, and common tips from Canadian bike owners.
Why should you remove an e-bike chain?
The reasons for removing a bicycle chain are not only because the chain is broken or needs repair, but also because you need to maintain or upgrade your ebike, which we usually categorize as follows:
- Cleaning and maintenance: The chain is part of the bicycle transmission system and is prone to accumulating dirt, grease, and other debris after frequent use. Removing the chain can clean it more thoroughly and extend the life of the chain and other transmission parts.
- Replacing the chain: The chain will wear with use, affecting the smoothness and efficiency of riding. If the chain is excessively worn, it may cause chain skipping or damage to the flywheel. Regular inspection and removal of the chain can help to detect problems and replace them in time.
- Adjustment and repair: If the chain breaks or skips, removing the chain can help repair or replace it. Removing the chain also helps adjust the precision of the speed change system.
- Storage: If the e-bike is not used for a long time, removing the chain can prevent the chain from rusting or damaging, especially when stored in a humid environment.
- Upgrades and modifications: If you plan to upgrade the transmission system of your e-bike, removing the chain is the first step to installing a new chain or other accessories.
When removing an e-bike chain, you need to use appropriate tools, such as a chain remover, to ensure that the operation is safe and does not damage other components.
Tools You’ll Need to Disassemble a Bike Chain
To get started, you'll need the right tools for the job. Here are the essentials:
- Chain Tool: The chain tool (or chain breaker) is the primary tool used to remove a bike chain. It allows you to push out the pins holding the chain together.
- Flathead Screwdriver (Optional): A small flathead screwdriver can sometimes help if your chain has a quick link or if you need to pry out stubborn parts.
- Master Link Pliers (Optional): If your bike chain uses a master link (a link that can be easily disconnected without tools), master link pliers are very useful.
- Lubricant or Oil: For maintaining your chain post-disassembly, having a chain lubricant or oil handy is a good idea.
- Rags or Cloths: To wipe off any grease or dirt from the chain during the process.
How to Disassemble a Bike Chain: Step-by-Step Guide
Now that you have your tools ready, let's walk through the process of disassembling your bike chain. The process might slightly vary depending on whether your chain has a master link or not, so we’ll cover both scenarios.
1. Identify Your Chain Type (Quick-Link or Regular)
Before proceeding, determine whether your chain has a quick link or is a regular chain:
- Quick-Link Chain: Many modern bike chains come with a quick link that allows you to easily disconnect and reassemble the chain without tools.
- Regular Chain: Older or standard chains require a chain tool to remove or install the chain.
2. Remove the Chain (For Quick-Link Chains)
If your chain has a quick link, follow these steps:
- Locate the Quick-Link: Quick links are usually a little different from the rest of the chain links. They often have a different shape or are marked with a logo.
- Use Master Link Pliers: Master link pliers are designed to pull the quick link apart easily. Apply the pliers and gently pull the quick link apart.
- Remove the Chain: Once the quick link is undone, you can simply pull the chain off the bike.
3. Remove the Chain (For Regular Chains)
If your chain doesn’t have a quick link, you’ll need to use a chain tool:
- Position the Chain on the Chain Tool: Place the chain on the chain tool. Make sure the chain is aligned properly so the pin can be pushed out.
- Align the Pin: Adjust the chain tool so that the pin is directly aligned with the chain tool's pin-pushing mechanism.
- Push the Pin Out: Turn the chain tool's handle to push the pin out of the chain. This will disconnect the chain. It’s important to push the pin out without damaging it. Be careful not to lose the pin.
- Remove the Chain: Once the pin is removed, the chain should come apart.
4. Clean and Inspect the Chain
Once the chain is disassembled, it’s a good time to clean and inspect it:
- Clean the Chain: Use a rag or cloth to wipe off excess grease and dirt from the chain. You can also soak the chain in a degreaser or use a chain-cleaning tool for deeper cleaning.
- Inspect for Wear: Check for any damaged or worn-out links. If the chain is significantly worn, it might be time to replace it.
5. Reassemble the Chain (If Needed)
If you are reassembling the same chain, follow these steps:
- Align the Links: Place the two ends of the chain together, aligning the links properly.
- Push the Pin Back In: Use the chain tool to insert the pin back into the chain.
- Check the Chain: Ensure the chain moves smoothly and does not have any stiff links.

Tips and Common Troubleshooting
- Pin Damage: If the pin is too damaged to be reused, you’ll need a new pin or master link for the replacement chain.
- Correct Chain Length: Ensure that the chain length is suitable for your bike’s gears before reassembling. A chain that’s too long or too short can cause issues with shifting.
- Avoid Over-Tightening: When reassembling the chain, avoid overtightening. This can lead to stiff links, which can make shifting gears difficult.
- Chain Lube: After reassembly, apply a light layer of lubricant to the chain to ensure smooth performance.
When Should You Replace Your Bike Chain?
Sometimes, disassembling the chain might reveal that it’s beyond repair. Here are some signs that indicate it’s time to replace the chain:
- Visible Stretch: If the chain is visibly stretched or has a lot of slack, it’s likely time for a new one.
- Skipping Gears: If the chain skips over gears when you shift, it could be a sign that it’s too worn.
- Rust and Corrosion: Rusted chains are not only inefficient, but they can also break more easily. If your chain has significant rust, it’s time for a replacement.
Final Thoughts
Disassembling your bike chain might seem like a daunting task at first, but with the right tools and a little patience, it’s a manageable process. Whether you’re cleaning, inspecting, or replacing a damaged chain, knowing how to properly disassemble it can save you time and money in the long run. Make sure to use a quality chain tool, inspect the chain for wear, and always reassemble it correctly to keep your bike running smoothly.
For Canadian cyclists, keeping your bike chain in top condition is especially important with varying weather conditions—from snowy winters to rainy spring days. Regular maintenance will ensure your chain lasts longer and performs at its best year-round.
