Learning how to change bicycle pedals is a great skill for any rider. Whether you’re swapping in a new set, upgrading for performance, or just doing general maintenance, understanding the correct technique gives you more control over your bike’s condition and performance.

In this guide, you’ll find step-by-step instructions, from identifying pedal threading to knowing how to remove bike pedals and fit replacements correctly. We’ll also cover the tools you’ll need, how to avoid common mistakes, and when it’s time to make the change. Once you’ve done it a couple of times, changing pedals becomes a quick, hassle-free part of your regular maintenance routine.

Tools You’ll Need for Changing Bicycle Pedals

Before getting started, it’s important to gather the right tools. Having the correct equipment not only makes the job easier but also helps prevent damage to your pedals or crank arms.

The most commonly used tools include:

• Bike pedal wrench – A thin-profile spanner designed to fit between the pedal and crank arm. Most pedals require a 15mm wrench, but it's worth checking the size beforehand.
  
• Bike pedal spanner – Similar to a pedal wrench but sometimes with a different handle shape for extra leverage. Either option will do the job well, depending on what feels more comfortable in your hand.
  
• Allen key (hex key) – Some pedals, particularly modern or clipless models, are fitted or removed using a hex key from the inside of the crank arm rather than with a spanner.
  
• Grease or anti-seize compound – Applying a small amount to the pedal threads before installation helps prevent them from seizing over time, making future removal much easier.
  
• Torque wrench (optional) – Useful for those who want to tighten pedals to the manufacturer’s recommended torque, especially on carbon or high-end bikes.

It’s also helpful to have a clean cloth nearby to wipe down the threads and remove any dirt or grit before fitting the new pedals. Working on a stable surface or using a bike stand can also make the process smoother and more comfortable.

Left vs Right Pedals: Threading and Identification

Not all pedals are the same, and understanding the difference between the left and right sides is key to removing and fitting them correctly. Mixing them up can lead to damaged threads, frustration, and a trip to the repair shop.

Each pedal is designed with specific threading:

• The right pedal (on the chain side) uses a standard thread — it tightens clockwise and loosens anticlockwise.
  
• The left pedal (non-chain side) has a reverse thread — it tightens anticlockwise and loosens clockwise.

This opposite threading isn’t a manufacturing quirk — it’s intentional. It prevents the pedals from loosening as you ride, which adds to overall safety and durability.

You’ll usually find markings stamped on the pedal axle or end cap:

• “R” for right
• “L” for left

If there are no markings, look closely at the thread direction or compare them side by side — the threading on the left pedal will angle in the opposite direction. Taking a moment to check this before removal or installation can save you a lot of trouble.

How to Remove Bike Pedals Safely and Efficiently

Once you’ve identified which pedal goes where, it’s time to take them off. While it may seem like a simple task, removing pedals the right way protects your crank arms and saves you hassle during reinstallation.

Start by making sure your bike is stable. A work stand offers the most convenience, but resting the bike upside down or against a solid wall will also work. Rotate the cranks so they’re horizontal — this gives you better leverage and keeps your hands clear.

Now it’s time to grab your tools. Insert the tool firmly into the appropriate slot or bolt, and remember:

• The right-hand pedal (chain side) loosens anticlockwise
• The left-hand pedal loosens clockwise due to its reverse thread

This is where many riders get stuck — the reverse thread on the left-hand side is a common source of confusion. If you're unsure how to unscrew a bike pedal, always remember that both pedals loosen towards the back of the bike.

If the pedals are stuck and won’t move, spray a little penetrating oil onto the threads, give it a few minutes, and then try again. Use steady, controlled pressure to avoid rounding off the flats or damaging the crank. This is especially helpful if you’re attempting cycle pedal removal after a long period of use.

Once the pedals come free, check for washers. If present, keep them safe as you may need them when refitting. If you’ve been wondering how to take off pedals on a bike with minimal fuss — this is the method trusted by most bike mechanics.

A Step-by-Step Guide: How to Change Bicycle Pedals and Fit Them Correctly

Getting new pedals fitted correctly is all about attention to detail. Once the old ones are off, take your time with the installation — it only takes a few steps, but doing it right makes all the difference.

Step 1: Identify Left and Right Pedals

Check the markings on your pedals — they’re usually stamped with an “L” for left and “R” for right near the thread or end cap. The right pedal tightens clockwise, and the left pedal tightens anticlockwise.

Step 2: Prepare the Crank Arms

Wipe the crank threads clean with a cloth to remove any old grease or dirt. Apply a small amount of bike grease or anti-seize compound to the new pedal threads. This helps prevent seizing and makes removing bike pedals easier later on.

Step 3: Thread Each Pedal In by Hand

Start with the right-hand pedal. Turn it clockwise into the driveside crank. Then move to the left-hand pedal, which threads anticlockwise into the non-driveside crank. Always thread them in by hand first — if it resists or feels misaligned, stop and start again. Cross-threading is easy to do and hard to fix.

Step 4: Tighten with the Proper Tool

Once both pedals are seated correctly, use the correct tool (depending on the pedal type) to tighten each one firmly. Most pedals don’t require excessive force — just a snug fit is enough. For those who prefer precision, a torque wrench can be used to match the manufacturer’s recommended setting.

Step 5: Double-Check and Test

Spin the cranks to ensure everything feels smooth and secure. If anything feels loose or uneven, stop and inspect the thread. This simple test can save you trouble on your next ride.

When to Change or Take Off Your Bike Pedals

Pedals are often overlooked when it comes to regular maintenance, but knowing when to replace or remove them can help improve ride quality and prevent unnecessary wear on your bike.

Here are a few common reasons to remove or change your pedals:

Wear and Tear

Pedals don’t last forever. If they feel loose, creak during rides, or if the grip surface is worn smooth, it’s time for a replacement. Worn pedals can lead to foot slippage and poor power transfer — not ideal for long rides or commutes.

Upgrading for Comfort or Performance

Switching to clipless pedals, flat pedals with better grip, or lighter materials can dramatically change your riding experience. Riders often want to change bicycle pedals to suit different riding styles — from commuting to trail riding.

Travel and Storage

If you’re packing your bike for travel, removing the pedals makes it easier to fit in a box or bag. Knowing how to take off pedals on a bike quickly and cleanly is a real time-saver.

Maintenance and Cleaning

Pedals can collect grime, road salt, and moisture, especially in wet weather. Removing bike pedals occasionally for a proper clean and re-grease helps preserve both the pedals and the crank arm threads.

Fitting Pedals to a New Bike

If you’ve just bought a new frame or upgraded to an e-bike, transferring your favourite pedals is simple — once you know how to remove bike pedals and fit them correctly.

Common Mistakes and How to Avoid Them

Changing pedals is a straightforward job, but a few easy-to-make errors can cause damage or lead to frustrating setbacks. Knowing what to watch out for can help you avoid unnecessary repairs and keep your bike running smoothly.

1. Mixing Up Left and Right Pedals

It might seem obvious, but this is one of the most common mistakes. The left pedal has a reverse thread, meaning it tightens anticlockwise. Installing it on the wrong side — or trying to turn it the wrong way — can quickly strip your crank threads.

Always double-check the markings: “L” for left, “R” for right, and remember that both pedals tighten towards the front of the bike.

2. Cross-Threading

Cross-threading happens when a pedal goes in at the wrong angle. It may feel like it’s going in smoothly at first, but it can damage the crank arm permanently. To avoid this, always thread the pedals in by hand first, then tighten them with a tool once they’re properly aligned.

3. Overtightening

You want your pedals secure, but cranking down too hard can strip threads or make future cycle pedal removal very difficult. Snug is enough. If you have a torque wrench, refer to the pedal manufacturer's guidelines — typically around 35–40Nm.

4. Forgetting to Use Grease

Skipping grease might not cause immediate problems, but over time, the pedals can seize inside the crank arm. This makes future pedal removal a real challenge, especially in damp or humid conditions. A dab of grease helps protect both threads and tools.

5. Using the Wrong Tool

Not all pedals are the same — some require an Allen key, others a bike pedal wrench or spanner. Forcing the wrong tool into place can damage the fitting. Before starting, check the correct tool size and type for your specific pedals.

By avoiding these issues, you'll save yourself time, frustration, and potential repair costs. Learning how to change bicycle pedals properly means fewer mistakes and more time on the road.
