Why Is My Bike Making a Rattling Noise? (Reasons + Fix)

You just bought a brand new bike, and now it’s making that rattling noise. Your fear of the sound has been amplified by your experience with other bikes.

If you want to know what might be wrong and how to fix it, keep reading. When you hear your bicycle making a rattling noise, you may think it’s something wrong with the chain or chainrings. But what if it’s not?

Why Is My Bike Making a Rattling Noise?

There are a number of reasons why your bike might be making a rattling noise. Some common causes include loose headset bolts, worn gears, and dirty bearings.

To fix these issues, you’ll need to take some basic steps, such as tightening bolts and adjusting gears.

Additionally, keep your bike clean and lubricated to avoid noise issues in the future.

6 Reasons Why your New /Old Bicycle is making a rattling sound

1. Loose Presta Valve Nuts or Bolts

If you’re noticing a rattling sound from your bicycle when you pedal, there’s a good chance that loose Presta valve nuts or bolts are to blame. To check for this, remove the front and back wheel and inspect both valves for any missing or loose nuts or bolts.

If you find any of these, replace them as soon as possible to prevent water from entering the rim and causing a rattling sound.

If you don’t have a wrench that fits your particular type of valve nut, try tightening both pedals with it. If that doesn’t work, you may need to take your bike in for repairs.

Another issue that can cause a rattling sound is a loose fit between the pedal and cleat. To adjust this, you’ll need to remove the crank arms and loosen the cups or bearings. Then, reposition the pump so there’s more clearance.

2. Poor Fork Lubrication

If you’re experiencing a rattling sound from your bicycle, it may be due to poor fork lubrication. Fork lubrication keeps the fork blades from making noise as they move up and down. If this lubrication is not present, the metal-against-metal contact will cause a rattling noise.

To prevent this problem, make sure to regularly apply drip or spray lube to the forks, the rollers, and the Chain Wheel Cylinder (if applicable).

Keep the bike clean and free from excessive rust and oxidation, which can also contribute to noise.

Lastly, lubricate the threads on the back of the crankarm to reduce the risk of stripping them.

3. Your bicycle headset could be loose

If you’re noticing a rattling sound from your bicycle headset, there is a good chance that it is due to a loose connection. To test the connection, you can tighten the screws on the headset.

If this does not solve the problem, your bottom bracket may be too tight. You can loosen the bolts and slide the bracket off of the head tube. If this still doesn’t fix the issue, your pump might be rubbing against the crank arm on each pedal stroke and causing a clunking noise.

4. Worn Out Bike Chain

Bike chains can cause rattling noises for a few reasons. Worn-out bike chains can be caused by a number of things, such as:

The chain is too tight when the cranks can’t be turned more. The chain is too loose when the cranks are tight.

The wheel should start moving inward, and that is when you need to tighten the axle nut.

Improvising with your thumb to get the wheel into the right place. If the bike chain is too tight or too loose, it can cause rattling noises.

5. Faulty Bike Hub

One common problem with bicycles is that the hub may be faulty. This can cause the bike to make a rattling sound. If the hub is not fixed, it can eventually wear out and cause the bike to make a rattling sound.

The hub may have been damaged in an accident and needs to be replaced. The hub may have become loose over time and needs to be tightened or replaced. The bearings in the hub may need to be lubricated and replaced if they are making a rattling sound.

6. Your Bike Pedal is Bad

A rattling sound can be caused by a loose pedal or bearings that need to be tightened. If you have an old bicycle, the pedals may just need to be greased up with some bike grease.

How can I fix the rattling noise coming from your bicycle?

Here are some things you can try:

Ensure you tighten your bike headset

If you’re experiencing rattling noises coming from your bicycle’s headset, it may be due to the headset being loose. To tighten it up, follow these steps:

First, get the center bolt as tight as possible by turning it with a torque wrench. Then, tighten the side bolts in a similar manner.

Be careful not to overdo it; you don’t want to damage your bike. If the rattling still persists, take your bike to the shop for further inspection.

Check for Loose Bolts in your back

Loose bolts can cause all sorts of problems, and rattling is one of them. If you have loosed the bolt in your back wheel or on a chainring because it came loose, then you should tighten it right away.

An easy way to check for loose bolts is to give the bike a shake, and if there are any rattles coming from your back wheel or chainring, then you should tighten them right away.

If the bolt is loose on your back wheel or chainring, then you will need to bring it into a bike shop and have someone tighten it for you.

Replace worn-out Bike chains

Chains make a lot of noise and can be replaced regularly. If you notice a rattling noise coming from your bike, it is likely that there is a tight link on the chain and it can be fixed without removing the chain.

Bike chains should be kept clean and lubricated to prevent them from making noise.

Proper Lubrication for your Bike forks

If you’re experiencing a rattling noise coming from your bicycle’s forks, you may want to lubricate them. This will reduce the noise they produce and help keep your bike running smoothly.

To lubricate your bike’s forks, you’ll need to remove the caps and dispense lubricant into the fork tubes. You can also tighten the bolts on your chainring to the correct torque spec.

Finally, apply the thread locker compound to the chainring bolts to prevent them from turning.

Consult a Professional

If you are experiencing rattling noise coming from your bicycle, it is important to consult a professional. A bicycle mechanic can diagnose the issue and provide a solution. If the rattling noise is severe, it may be necessary to replace the bicycle’s frame.

What are the preventative measures for a rattling noise on your bike?

Preventative measures include re-tightening the bolts of your bicycle. The nuts and bolts that hold your bike together can loosen up over time, causing rattling noises when you ride. It is important to check these bolts and tighten them when needed.

If you are experiencing a rattling noise, it is best to consult with a professional bicycle mechanic.

What are the Other Bicycle Noises you should be aware of?

There are a few different types of noises that your bike can make, and it’s important to be aware of them so you can identify the issue and fix it. Some common bicycle noises are:

Dry chain: This noise comes from the drive train when the chain is dry. It will often sound like a squeaking noise.

Brake pads: If your brake pads are worn, they may start to squeak when you apply pressure to them. This noise usually comes from the front or rear brakes.

Worn bottom bracket: A worn bottom bracket can cause a clunk noise or click sound from the front of the drive train.


When you’re riding, it’s important to be aware of the noises your bike makes. It can help you identify issues with your bike before they become serious problems that cost a lot of money to fix.

Bike noise can sometimes be due to a worn-out part. If you’re not sure what’s causing the noise, degreasing/cleaning and applying lubrication can help keep your bike’s drivetrain running smoothly.


How do I know if my bike needs servicing?

The answer to this question is not as straightforward and simple as it may seem. The frequency of the rider’s rides, their weight and the type of terrain they’re riding on can all have an effect.

If you’re a novice rider, chances are your bike will need servicing more often than someone who rides it regularly for exercise. A bike that’s not serviced regularly will need a service before the rattle becomes too much of an annoyance.

If you’re riding on dirt tracks, there’s a better chance your bike will rattle than if you’re riding on a smooth road. Dirt roads can be bumpy and the vibrations from these bumps can cause the bike to rattle.

Why does my bike creak when I pedal hard?

A creaking sound might be a sign of your bicycle’s brake pads rubbing against the rims. If you’re not sure, check to see if there is any dirt between them or on the rims. If the brake pads are too high, you may need to adjust them or replace them as they could be rubbing against your bicycle’s rim and causing a creaking sound when you pedal.

How do you fix a rattling bike chain?

If you have a rattling bike chain, there are a few possible solutions. You can lubricate the chain with a greasy substance, such as WD-40. If that doesn’t fix the issue, you can replace the chain.
