Belt Drives vs Chain for Electric Bikes: Pros & Cons
 The Short Answer is: |
Belt drives for electric bikes are generally quieter and require less maintenance, but they are more expensive and difficult to replace. They also have a longer lifespan than chains. Chains, on the other hand, are cheaper and more efficient at low power outputs, but they require more maintenance and wear out quicker. |
Belt drives and chain drives are two of the most common types of drives used in electric bikes. Both have their advantages and disadvantages and choosing between them can be a difficult decision for many e-bike enthusiasts.
In this article, we will explore the pros and cons of belt drives and chain drives for electric bikes, and help you make an informed decision on which one to choose. Whether you are a seasoned e-bike rider or a beginner, this article will provide you with valuable insights on the topic “Belt Drives vs Chain for Electric Bikes”.

Advantages of Belt Drives for Electric Bikes
When it comes to electric bikes, belt drives have several advantages over chains. Firstly, belt drives are incredibly low maintenance and don’t require frequent oiling and cleaning as chains do.
They are also generally quieter, making for a more pleasant riding experience. Additionally, belt drives are lightweight, tipping the scales at around 87 grams, while a standard bike chain will weigh approximately 300 grams.
Disadvantages of Belt Drives for Electric Bikes
While belt drives have their advantages for electric bikes, there are also some disadvantages to consider. One of the main drawbacks is the cost. Belt drives are generally more expensive than chain drives, both in terms of production and replacement costs.
Additionally, belt drives require specific gearboxes, which can add to the overall expense. Another disadvantage is that belt drives are not as efficient as chain drives, which can result in a loss of power and speed.
Finally, while belt drives are generally low maintenance, they can be more difficult to repair or replace if they do break. Overall, it’s important to weigh the pros and cons of both belt and chain drives when choosing the best option for your electric bike.
Advantages of Chains for Electric Bikes
When it comes to electric bikes, chains have some distinct advantages over belt drives. Firstly, chains are cheaper and easier to replace, making them a more cost-effective option.
Additionally, chains are more efficient at low power outputs, making them ideal for city riding and commuting. While chains do require more maintenance and wear out quicker, their affordability and efficiency make them a popular choice for many electric bike riders.
Disadvantages of Chains for Electric Bikes
While chains may be cheaper and more efficient at low power outputs, they come with several disadvantages for electric bikes. Chains require more maintenance than belt drives and are more prone to wear and tear.
Chains can also be messy and deposit particles if not frequently lubricated. Additionally, chains are less efficient at low-power inputs and can cause more stress on the bearings, leading to quicker wear and tear.
Finally, chains have fewer options for components compared to chain drivetrains, which have many options for types of chains, sprockets, cassettes, and chainrings.
Factors to Consider When Choosing Between Belt Drives and Chains
When choosing between belt drives and chains, there are several factors to consider. Belt drives are less efficient at low power inputs and cost more than chain drives.
However, they are quieter and require less maintenance than chains. Chain drives are more durable and provide a more authentic riding experience, but they require more maintenance and can be noisier than belt drives.
Additionally, chain drives are typically less expensive than belt drives. Ultimately, the choice between belt drives and chains depends on personal preference and the intended use of the drive system.
Maintenance Tips for Belt Drives and Chains
When it comes to electric bikes, belt drives, and chains are two popular options. While belt drives are cleaner and quieter, they require more maintenance than chains. Here are some tips to keep your belt drive or chain in top condition:
Proper mounting:
For belt drives, avoid prying or rolling the belt onto the sheave as this can damage the tensile cords and reduce belt life. Always check sheaves for wear or damage before mounting a belt. Nicks, worn sheaves, and sharp edges can damage belts.
Storage and handling:
For belt drives, proper storage, and handling are important to prevent damage to the belt. Store belts in a cool, dry place away from direct sunlight and chemicals. Avoid bending or twisting the belt during handling.
Cost:
Belt drives cost more than chain drives, so be prepared to spend more on maintenance. A new belt can cost $80-$100, and you’ll also need an internal gear hub, which can cost anywhere from a few hundred to well over $1000 for a high-end option like Rohloff.
Availability of replacement parts:
Belt-driven equipment uses readily available components, so replacement parts can be easily obtained from local distributors. Sheaves and pulleys are usually less expensive than chain drive sprockets and have little wear over long periods of operation.
Consistent administration:
Chain drives need consistent administration, including lubrication and cleaning, to keep them running smoothly. Neglecting chain maintenance can lead to premature wear and tear, which can be costly to repair
By following these tips, you can ensure that your belt drive or chain lasts longer and performs better, giving you a smoother and more enjoyable ride.
Frequently Asked Questions Related to Belt Drives and Chains for Electric Bikes:
Are belt drives more efficient than chains for electric bikes?
Belt drives are more efficient than chain drives at high power outputs and when going up inclines. However, at standard or low power outputs, which is most likely what you will be using if you are doing city riding, belt drives are less efficient than chain drives.
How long do belt drives last on electric bikes?
Belt drives on electric bikes can last between 15,000 km to 80,000 km, depending on the manufacturer and usage. They can last between 5 to 10 times longer than chains.
Can I switch my electric bike from a chain to a belt drive?
Yes, it is possible to switch an electric bike from a chain to a belt drive.
Conclusion: Belt Drives vs Chain for Electric Bikes
In conclusion, both belt drives and chain drives have their pros and cons when it comes to electric bikes. Belt drives are quieter, cleaner, and require less maintenance, but they are more expensive upfront and may cause the bottom bracket and rear hub to wear out faster.
Chain drives are more efficient at low power inputs, easier to repair on the road, and have a lower upfront cost, but they require more maintenance and are more prone to failure with mid-drive motors.
Ultimately, the choice between belt drives and chain drives will depend on your personal preferences and needs. If you prioritize a quiet and low-maintenance ride, a belt drive may be the way to go. If you prioritize efficiency and affordability, a chain drive may be the better option.
