Can you run a marathon with shoes full of holes? The same goes for riding a bike with a worn-out chain. You may try to keep going on, but it will cause you a lot of frustration and severe damage down the line.
The chain is an important part of your bike, and if you overlook it, damage can spread to other costly parts like the cassette or chainrings. That is why you should learn how to change a bicycle chain so that you can save time, money, and avoid frustration on the road.
In this guide, we will help you learn how to replace your e-bike or standard chain step by step, along with the tools you need. You will also learn how often to replace the chain and some expert tips to extend its lifespan.
Let’s dive in!
Common Signs Your Bike or E-Bike Chain Needs Replacing
Your bicycle chain can never fail overnight. Instead, it loses its efficiency gradually and shows you some warning signs. These early and visible signs include:
- Skipping Gears: On standard bicycles, your chain would slip when you pedal hard. On e-bikes, the motor or pedalling feels less responsive, or you feel like you're losing power. This often happens when the chain becomes loose or stretches over time.
- Unusual Noise: If you notice grinding or any clicking sounds, it usually means the chain is wearing unevenly. E-bikes will make a louder noise under motorised power if the chain is worn.
- Visible Wear: If you see visible rust or excessive stretch (the gap between links becomes noticeable), it's time to change the chain. On e-bikes, the extra power from the motor puts more strain on the chain, which can make it wear out faster—so it’s important to check it regularly.
Essential Tools for Changing a Bike or E-Bike Chain
Before you start replacing the chain, you should have the right tools on hand: These tools may include:
- Chain wear indicator – To check if your chain is stretched beyond the recommended limit.
- Chain breaker – To remove the old chain.
- Master link pliers (if applicable) – Helpful if your chain uses a quick link.
- Replacement chain – Choose one that matches your bike’s speed (e.g., 9-speed chain for a 9-speed bike, 11-speed for 11-speed, etc.). For e-bikes, choose a chain rated for higher torque, as they’re built stronger to handle motor power.
- Bike stand (optional) – This is optional to make the process easier, but it is not essential.
- Gloves and rag – To keep your hands clean and manage grease.
- Chain Lubricant - To keep the new chain running smoothly.
Step-by-Step Process to Replace a Bicycle Chain or E-Bike Chain
Now let’s walk through the process step by step and see exactly how to change the chain on an e-bike or a regular bicycle.
1. Get Your Bike Ready
First of all, put on gloves to keep your hands clean. Then place the bike on a stand or turn it upside down if you don’t have a stand. If you’re working on an e-bike, the power should be switched off, or you can remove the battery if possible.
2. Make the Chain Loose
Now shift into the smallest gear at the front and the smallest gear at the back. This reduces tension on the chain and makes it easier to remove.
3. Remove the Old Chain
If your bike has a quick link (a special link that looks slightly different from the rest), use master link pliers to open it. If not, use a chain tool to push one of the pins out. Once it’s open, gently pull the chain away from the gears and derailleur.
4. Measure the New Chain
Now lay the new chain next to the old one to match the length. If the old chain was excessively worn, use the “big-big method.” As per this method, wrap the chain around the largest chainring and largest cog, then add two extra links.
For e-bikes, always use a chain designed for e-bike use because the motor puts much more force on it than your legs alone.
5. Thread the New Chain
Next, start by placing the chain over the front chainring. Guide it carefully through the jockey wheels of the derailleur and finally over the cassette at the back. Take your time to ensure the chain follows the correct path, as a mistake here will affect the smooth shifting process.
6. Connect the Chain
If your chain has a quick link, connect both ends and position the link on the top part of the chain between the cassette and the chainring. Hold the rear brake and push the pedal forward until you hear it click into place.
If your chain uses a connecting pin, press it in with the chain tool and break off the guide tip. Always check that the link bends smoothly once connected.
7. Test the Chain
In the next step, turn the pedals slowly and shift through every gear to check that the chain runs smoothly. If you notice skipping or slipping, especially on an e-bike, it could mean your cassette or chainring is also worn and may need replacing.
8. Lubricate and Finish
After testing, apply bike chain lubricant along the full length of the chain while slowly pedalling. After a few seconds, wipe off any excess lubricant with a rag. The right amount of lube will protect the chain without attracting too much dirt.
If you are using an e-bike, lubricate and clean your chain more often, as the higher torque and speed attract dirt faster and increase wear.
How Often Should You Replace a Bike or E-Bike Chain?
Here is a quick guide for you to understand how often to replace a bike chain:
|
Bike Type |
Typical Chain Lifespan |
Things That Shorten Lifespan |
|
Standard Bike |
2,000 – 3,000 km |
Riding in mud, rain, poor lubrication, and skipping maintenance |
|
E-Bike |
1,000 – 1,500 km |
High motor assist, steep climbs, heavy loads, dirt buildup |
Pro Tip: Use a chain wear indicator tool to check every few hundred kilometres. If the chain shows too much stretch, replace it right away to prevent bigger repair costs.
