How do you clean and lubricate the chain on your electric bike?
A clean, well-lubricated chain is essential to guarantee the best performance and extend the life of your electric bike's transmission.
It's a simple maintenance task that you can carry out at home, keeping your e-bike running like new.
Why do I need to clean and lubricate my chain regularly?
A dirty chain:
- Accelerates wear on your transmission
- Reduces your bike's performance
- Gives your bike a neglected look
Perhaps you've been a little slow on the uptake? Don't worry, you're not alone. Fortunately, cleaning and lubricating the chain on your electric bike is easier than it looks.
Pro tip: Do you have an electric bike with a belt drive instead of a chain? No need to lubricate! These belts are long-lasting, low-maintenance and rust-proof.
How often should you clean your chain?
This depends on several factors:
- Number of kilometers traveled
- Weather conditions and type of terrain (mud, dust, rain)
- Motor type(central motor or hub motor)
In general: clean the chain every 1 to 4 weeks. Do you hear noises? See dirt? → It's time to act.
Materials required
- Special bike degreaser
- Chain lubricant (dry or wet, depending on weather conditions)
- Toothbrush or bike cleaning brush
- Clean, dry cloth
- Bucket of soapy water
Steps: cleaning and lubricating an electric bicycle chain
Follow these simple steps, whether your bike is new or refurbished :
1. Degrease chain
- Spray bike degreaser on chain, cassette and chainrings

2. Brush
- Use a toothbrush or a special chain brush
- Clean: cassette, derailleur pulleys, sprockets and each link
3. Rinse with soapy water
