Do electric bikes have chains?
While many people are familiar with traditional bicycles having chains, you might wonder whether electric bikes use them too. In fact, electric bikes rely on chains just like conventional bikes, but with different demands due to the motor-driven power. Choosing the right chain is crucial for ensuring optimal performance and longevity of your e-bike. In this article, we’ll discuss the key factors to consider when selecting the best chain for your electric bike and how to make the right choice for your needs.
Differences Between eBike Chains and Traditional Bicycle Chains
An electric bike places significantly higher demands on the chain due to the electric drive compared to a regular bike. The chain must withstand higher torque and increased load, especially when starting, climbing, and accelerating.
Higher Torque and Greater Durability
The electric motor in an eBike puts greater strain on the chain. Traditional bicycle chains are not designed to handle these forces, which is why eBike chains are made from specially reinforced materials. They are more durable and can withstand higher tensile forces.
Wider Chains for Electric Bicycles
Compared to traditional chains, eBike chains are often wider to better transfer the higher power and minimize wear. Typical eBike chains range from 5.8 mm to 6.6 mm in width, depending on the model, and are designed to meet the specific demands of electric drives.
Important Factors When Choosing an E-Bike Chain
When selecting the right chain for your ebike, there are several key factors to consider:
Chain Material
The material influences the durability and longevity of your chain. Steel alloy chains offer high tensile strength, while nickel-plated chains provide additional protection against rust and corrosion. In Germany, where the weather can change frequently, rust-resistant chains are beneficial because they last longer and are less prone to weathering.
Chain Compatibility
The chain must be compatible with the number of gears and the shifting system of your eBike. Whether it's an 8-speed, 9-speed, or 11-speed bike, each chain is designed for a specific shifting system. Before purchasing, you should check whether the chain is compatible with your eBike’s shifting system to ensure smooth shifting performance.
Surface Coatings
The right coating ensures a longer lifespan and smoother operation of the chain. Nickel-plated or titanium-coated chains are particularly durable as they reduce wear due to lower friction. They also offer protection against external elements such as moisture and dirt, which is especially advantageous in Germany's climate.
Best Ebike Chain Brands in the Market
Shimano is one of the most well-known brands when it comes to eBike chains. Their chains are designed for maximum durability and excellent compatibility with Shimano shifting systems. They are particularly resistant to wear and are therefore the perfect choice for eBikes that are exposed to high loads.
In addition to Shimano, KMC offers a wide range of high-quality eBike chains. KMC is known for its robust construction and long lifespan. KMC chains are also compatible with various shifting systems and provide an excellent alternative to Shimano, especially for riders who value high durability.

Correctly Maintaining and Caring for Your E-bike Chain
Electric bike chains endure more strain and pressure compared to traditional bike chains, making proper maintenance essential for longevity and optimal performance. To help you maintain your e-bike chain, here are some in-depth tips and techniques:
1. How to Choose the Right Lubricant?
The choice of lubricant is crucial for chain maintenance. Different riding conditions require different types of lubricants:
-
Dry Lubricant: Ideal for dry and dusty environments. Dry lubricants usually keep the chain cleaner, preventing dirt buildup, but may not last as long in wet conditions.
-
Wet Lubricant: Suitable for rainy or muddy conditions, as it provides better water resistance, preventing rust. However, it may attract more dirt, so it’s best suited for wetter environments.
It’s important to switch between lubricants based on weather conditions and riding environment.
2. Regular Deep Cleaning of the Chain
While basic cleaning can be done daily, performing a deep clean of the chain can significantly improve its lifespan and performance. The proper steps include:
-
Use Chain Cleaner: Opt for a specialized chain cleaner and a brush to clean the chain. Apply the cleaner evenly, rotating the pedals to allow the cleaner to penetrate and remove dirt and grime from each part of the chain.
-
High-Efficiency Cleaning Tools: There are dedicated chain cleaning devices available that help remove more dirt from hard-to-reach areas.
-
Eco-Friendly Cleaners: Using eco-friendly cleaners helps not only clean the chain effectively but also protects the environment. Choose cleaners that are gentle on the chain material to avoid corrosion.
After cleaning, make sure the chain is thoroughly dried, and avoid leaving moisture that could affect lubrication.
3. Checking Chain Wear and Replacing When Necessary
Chain wear is one of the most common maintenance issues for electric bike chains. Over time, chains will naturally stretch and wear out due to usage and load. Here’s what you need to check:
-
Chain Wear Detection Tool: Use a chain wear tool to accurately check if the chain is over-worn. Generally, if the wear exceeds 1%, it’s time to replace the chain.
-
Tension Check: Ensure the chain is always properly tensioned to avoid slipping or skipping while riding. A loose chain can be dangerous and affect your riding experience.
-
Chain Elongation Check: Over time, chains will elongate due to metal fatigue. Regularly check the chain’s length and replace it when it exceeds the recommended limits.
4. Properly Adjusting the Gear System in Tandem with the Chain
The gear system in your e-bike has a significant impact on the chain’s performance. To prevent excessive wear or skipping, make sure the gear system is properly adjusted:
-
Gear Adjustments: Ensure the gear system is properly calibrated so that shifting is smooth and efficient. Incorrect gear alignment can cause the chain to slip or wear prematurely.
-
Chain and Gear Compatibility: Check the compatibility between the chain and gears. Poor chain-to-gear engagement can lead to excessive wear.
5. Regular Maintenance of the E-bike’s Drivetrain System
Aside from the chain itself, the other components of the e-bike drivetrain also need regular checks and maintenance:
-
Check the Gears and Freewheel: Proper engagement between the chain and gears is crucial. Check for excessive wear on the gears or freewheel, and replace them if necessary.
-
Check Chainwheels and Pulleys: Regularly inspect the chainwheels and pulleys, ensuring they are free of debris and properly lubricated. Worn pulleys or chainwheels can affect chain performance and lifespan.
6. Things to Consider When Replacing the Chain
If your chain needs replacement, make sure to choose a chain that matches your e-bike’s specifications and riding needs. Different brands and models of chains may have slight variations, so choosing the wrong chain could negatively impact performance and potentially damage the drivetrain.
