Ultimate Guide to Silencing Your Electric Bike's Noises

Many times, we find ourselves puzzled by squeaks or unexpected noises coming from our newly assembled or regularly used electric bicycles. These noises often stem from improper assembly or wear and tear of components over time, indicating potential issues. Addressing these problems early can prevent them from worsening in the future. If your electric bike starts making noises, it’s crucial to stop and check it before continuing your ride.

Why is my electric bike making strange noises?

Identifying the source of the squeaking is crucial. Here’s how you can diagnose and fix it, as there are many parts on a bike that can produce noise. Once you pinpoint the source, refer to the relevant component below.


The contact between the wheel and the brake pads often causes squeaks. First, check if your wheels are properly secured in the dropouts, where the wheel axles attach to the bike frame. Misalignment can cause the wheel to rub against the brake pads. Remove the wheel, tighten the quick-release skewer, and securely fix it in the dropouts.


A squeaky chain is likely dry and in need of thorough cleaning and lubrication.


If the crankset is the source of the noise, loose bolts might be the culprit. Grab the crank arms (the parts connecting the pedals to the bike) and twist them to see if they move side to side. If they do, tighten them using the appropriately sized hex wrench.


Dry pulleys can often cause the derailleur to squeak. Clean them thoroughly with a dry cloth, then apply a drop of lubricant to each pulley’s axle. Also, lubricate the derailleur’s pivots by turning the pedals.


A common question is why the bike makes noise when pedaling. The pedals themselves might be the issue. Check if they are tightened securely or if the pedal threads are damaged. If the threads are damaged and you can’t tighten the pedals, replace them promptly.


The rails connecting the saddle to the seat post can also be a source of squeaks. Tighten the bolts securing the saddle using an appropriately sized hex wrench. If the saddle tilts and squeaks, consider taking it to a nearby bike shop.

How to Fix Squeaky Bike Brakes?

Fixing noisy brakes on an electric bike is straightforward. Follow these steps to silence your brakes

Check the Brakes

It’s easy to determine if the front or rear brakes are at fault. During a ride, test the brakes individually. If the front brake is noisy, the sound will come from the left side. If the rear brake is noisy, the sound will come from the right side. If both brakes make noise, adjust both front and rear brakes.

Clean the Rotors

If possible, use rubbing alcohol to clean the disc brake rotors and wipe them with a clean cloth or towel. Clean the brake pads with a degreaser if they are still thick; if they are thin, replace them. After cleaning the brake pads, wait for them to dry completely before reassembling.

Replace Brake Pads

Replacing the brake pads follows the same steps for both the front and rear wheels. If your bike’s brakes are squealing when applied, the brake pads are likely worn out. Worn brake pads can’t grip properly and cause squealing, reducing braking efficiency.


These solutions will help you fix the squeaking noises on your electric bike, ensuring a smoother and more enjoyable ride. Regular maintenance and timely addressing of any noises can extend the life of your bike and make your rides more pleasant.
