Why is My Ebike Squeaking – And Other Ebike Noise Questions Answered

Well, issues occur. One day you might come to find that your ebike is making strange noises. What do these sounds mean? Why do you heat squeaking noises from your electric bike, and is this normal?

Let’s take a look at some of the most common ebike noise issues and what they might mean.

Where Can the Noise Come From?

Actually, no one can say it for sure until you have checked it out. The noise your ebike makes can be coming from anywhere, including the motor, controller, brakes, spokes or even the frame itself.

However, let’s discuss the most common scenarios.


If you hear a squeaking sound when braking, this is likely caused by the brake pads. Over time, the brake pads will become worn and need to be replaced. If the noise continues even after replacing the brake pads, then it’s possible your brake rotor may also be damaged or warped and require replacement.

Brakes can also make rattling noises if the brake pads move within the caliper or are not properly adjusted. Also, check for any objects or stones that may have become trapped inside your brakes and scrape against them as you ride.

If you find an issue in the brake, it’s best to visit a certified ebike technician who can assess the problem and replace the necessary parts.


The chainring is the cog on the crank arms and it can make a squeaking noise if it gets wet or dirty. To prevent this, regularly clean and lubricate your chainset to reduce wear and tear. A worn chain will also cause a noise as it slips over the teeth of the sprocket, so it’s best to replace it when necessary.

Many chainring issues can also come from chain tension. If the chain is too loose, it will slip and make noise as it passes over the sprocket. On the other hand, if the chain is too tight, it can cause a rattling sound when pedaling due to increased friction between the links of the chain.


Here is another reason why your ebike may be making noise. The derailleur is part of the bike that moves the chain when you shift gears, and it can make a squeaking or rattling sound if it’s not properly adjusted or lubricated. To fix this issue, first, check to make sure all bolts are properly tightened and then apply some lubricant to the derailleur.

Another problem that can arise is when the chain drops off the sprocket. This can happen if you shift too quickly or have a worn chain. If this happens, you will need to move the derailleur until the chain is back on and then adjust it so that it doesn’t happen again.


Why not? The issue here is usually caused by the bearings being worn out. In order to fix this, you’ll need to remove your pedals and replace the bearings.

Pedals oftentimes make a creaking noise if they are not tightened properly. Check the bolts of your pedals and make sure they are properly tightened. If the noise is from the pedal, this can indicate a worn-out bearing or a lack of lubrication.

Regular maintenance is key to keeping your ebike running smoothly and preventing any noise issues. It’s better to get your ebike checked out by a professional to determine the root of the noise and address it accordingly.


The saddle of your ebike can also make noise if it’s not properly adjusted or if the seatpost is too loose. Make sure to check the bolts and tighten them as needed, or better yet, replace the seatpost with a new one.

Saddles often make creaking sounds if they are not properly lubricated. You can apply lube or grease to the saddle rails to help reduce the noise and give it a smoother ride.

The saddle can also make rattling sounds if it gets loose and moves. If the screws are not secured properly or the clamp is worn out, then you will likely need to replace them with a new one.

Thru Axle

The thru-axle on an ebike is the part that connects the wheel to the frame, and it can make a rattling sound when loose. Make sure to check the bolts on your thru axle and tighten them as needed. If they are worn out or broken, you will need to replace them with new ones.

Thru-axle, however, is the less likely reason for any noise coming from your ebike. If you hear a rattling sound when pedaling, it’s usually due to an issue with the chain or derailleur, as previously mentioned.

Should You Check Your Electric Bikes for Adults Manually?

Yes, it’s important to check your ebike for any potential issues before you go out for a ride. This includes checking the brakes, chainring, derailleur, pedals and thru-axle to make sure they are all properly adjusted. Additionally, you should also check to make sure that everything is securely tightened and lubricated as needed. If you find any issues, it’s best to address them sooner rather than later to avoid any damage or noise coming from your ebike.

However, always doing everything on your own has a risk of making an error and harming your bike. That’s why it is recommended that you take your ebike to a professional for regular maintenance, so they can properly assess and address any issues before they become worse.

To Sum Up

We highly recommend you check your electric bike on addmotor.com before you use it and take it to a professional for regular maintenance. Even if there are no strange noises coming from your ebike, it’s still important to check the brakes, chainring, derailleur, pedals and thru-axle.

Be careful and happy riding!
