Mountain Bike Pedal Removal: A Step-by-Step Guide

Last Updated on October 24, 2026 by Jaxon Mike

Removing mountain bike pedals might seem tricky, but it’s quite straightforward with the right tools and technique. You’ll need a pedal wrench or Allen key, and knowing which way to turn is key: righty-tighty, lefty-loosey doesn’t always apply here. For most pedals, you turn counter-clockwise to loosen.

Many riders find this a common maintenance task. It’s often done to swap pedals, perform deeper cleaning, or make it easier to transport your bike. Understanding which side is which and the correct direction for removal prevents frustration and potential damage to your crank arms. We found that a little preparation goes a long way.

• Pedals have specific left and right sides.
• Most pedals loosen by turning counter-clockwise.
• A pedal wrench or Allen key is typically required.
• Always check pedal threading if unsure.

Let’s walk through exactly how to get those pedals off your mountain bike, step by step.

Getting Your Bike Pedals Off Safely

Removing your mountain bike pedals is a common maintenance task. You might be looking to swap them out for a new set or just give your bike a thorough cleaning. Knowing how to remove pedals correctly will save you time and prevent damage to your bike’s cranks. Let’s make sure you’re equipped with the right knowledge and tools before you start.

Understanding Pedal Mechanics and Your Tools

Before you grab a wrench, it’s essential to understand how bike pedals are threaded. Most pedals screw in a specific direction. This can sometimes be confusing because it’s different from how you tighten other bolts.

Which Way Do Pedals Loosen?

This is the most common question, and the answer can surprise some people. For the vast majority of pedals, you’ll turn them counter-clockwise to loosen them. This is often called “lefty-loosey.” However, remember that this applies differently to each pedal.

Identifying Left and Right Pedals

It’s critical to know which pedal is which. Mountain bike pedals are designed specifically for the left and right sides of your bike. You’ll usually find markings on the pedals themselves. Look for an ‘L’ for the left pedal and an ‘R’ for the right pedal. Sometimes these are small and subtle, so check the spindle or the body of the pedal carefully.

The left pedal (non-drive side) has a reverse thread. This means you actually turn it clockwise to loosen it. Yes, you read that right! The right pedal (drive side, or the side with the crank arm that connects to the chain) has a standard thread. You’ll turn it counter-clockwise to loosen it. We found this distinction to be the most common point of confusion for beginners.

Tools You’ll Need

You generally have two main tool options for pedal removal. Having the right tool makes the job much easier and safer for your bike.

Pedal Wrench

A pedal wrench is specifically designed for this job. It’s usually thinner than a standard wrench, allowing it to fit between the pedal and the crank arm easily. They often have a 15mm opening, which is standard for many pedals. Many cyclists find this the easiest tool to use because of its leverage and slim profile.

Allen Key (Hex Wrench)

Some pedals, especially newer or high-end ones, don’t have a spot for a wrench on the outside. Instead, they have a hex socket on the inside of the pedal spindle, where it meets the crank arm. For these, you’ll need an Allen key, typically 6mm or 8mm. Make sure the Allen key fits snugly to avoid stripping the bolt head.

Step-by-Step Pedal Removal Guide

Now that you know your tools and the threading, let’s get those pedals off. Preparation is key to a smooth removal process. Have your tools and a rag ready.

Positioning Your Bike for Easy Access

For best results, you want to position your bike so you can apply firm, controlled pressure. Many mechanics suggest leaning the bike against a wall or using a bike stand if you have one. This keeps the bike stable while you work.

For the drive-side pedal (right side), the crank arm should be in the forward-most position. For the non-drive side pedal (left side), position the crank arm in the rear-most position. This setup utilizes your body weight effectively for loosening.

Removing the Drive-Side (Right) Pedal

This is the pedal on the side where your chainrings are located. Remember, this side has a standard thread. You want to loosen it by turning it counter-clockwise.

Place your pedal wrench or Allen key onto the pedal spindle. If using a pedal wrench, position it so you can push down with your foot or body weight. Aim to turn the wrench counter-clockwise. If using an Allen key, insert it into the back of the pedal spindle and turn counter-clockwise.

You might need to apply a good amount of force, especially if the pedals haven’t been removed in a while. Research and found that a consistent, firm pressure is better than sudden jerky movements, which can slip. Once it breaks free, it should unscrew relatively easily.

Removing the Non-Drive-Side (Left) Pedal

This is the pedal on the side opposite your chainrings. This side has the reverse thread. To loosen it, you need to turn it clockwise.

Again, position your wrench or Allen key. If using a pedal wrench, you’ll be pushing up or pulling towards you to loosen. If using an Allen key, insert it into the spindle and turn it clockwise. It might feel counter-intuitive, but trust the process!

Apply firm, steady pressure. Just like the other side, it might be tight. We found that applying pressure smoothly helps to avoid damaging the crank arm threads. Once you feel it loosen, continue unscrewing it until it comes off completely.

Dealing with Stubborn Pedals

Sometimes, pedals can be incredibly stubborn. Years of grime, rust, or overtightening can make them difficult to remove. If you’re struggling, here are a few tips we found helpful:

• Penetrating Oil: Spray a good quality penetrating oil onto the threads where the pedal meets the crank arm. Let it sit for at least 15-30 minutes, or even overnight if possible. This helps break down rust and corrosion.
• Gentle Tapping: After applying oil, you can try gently tapping the end of your wrench with a rubber mallet. This vibration can help the oil seep in and loosen things up.
• Heat (Use with Caution): Some professionals suggest applying a little heat with a heat gun to the crank arm around the pedal spindle. The idea is to expand the metal slightly. However, this carries a risk of damaging crank arm coatings or bearings, so it’s best left as a last resort and done very carefully.
• Ensure Correct Tool Fit: Double-check that your wrench or Allen key is fully seated in the pedal. A loose fit is the quickest way to strip the bolt head.

Quick Checklist for Pedal Removal

To ensure you’re ready and have a smooth experience, use this quick checklist:

• Identify L/R Pedals: Make sure you know which pedal is which.
• Gather Tools: Have your pedal wrench or correct-sized Allen key ready.
• Position Bike: Stable bike means easier work.
• Correct Direction: Remember: Right pedal = counter-clockwise. Left pedal = clockwise.
• Apply Firm Pressure: Steady force is your friend.
• Clean Threads Afterward: Once removed, clean the threads on the crank arm.

By following these steps, you should be able to remove your mountain bike pedals with confidence. It’s a skill that every cyclist can learn and will serve you well for future maintenance!

Conclusion

You’ve now got the knowledge to confidently remove your mountain bike pedals. Remember that the key is identifying left from right and understanding those threads – the right pedal loosens counter-clockwise, while the left pedal tightens counter-clockwise (meaning it loosens clockwise). Having the right tools, like a pedal wrench or the correct Allen key, makes all the difference. Don’t get discouraged if they’re tight; a little penetrating oil or steady pressure usually does the trick. Now you’re ready for maintenance, upgrades, or just getting your bike packed up!

Frequently Asked Questions

What if my pedals are really stuck?

If your pedals are stubborn, first try applying a good penetrating oil to the threads and let it soak in for at least 30 minutes. Gentle tapping with a rubber mallet on the wrench might also help break them loose. Always ensure your tool has a secure fit to avoid stripping the pedal spindle.

Can I use a regular wrench instead of a pedal wrench?

While a regular wrench might work in a pinch, a dedicated pedal wrench is usually thinner and offers better leverage. This makes it easier to fit into tight spaces and apply the necessary force without slipping. Using the correct tool prevents damage to your crank arms and pedals.

How do I know if I have reverse-threaded pedals?

Most pedals are threaded consistently: right pedals loosen counter-clockwise, and left pedals loosen clockwise. You’ll typically find an ‘L’ or ‘R’ marking on the pedal spindle. If you’re unsure, consult your pedal manufacturer’s documentation or look for external wrench flats on the pedal body.

Do I need to grease the pedal threads when I reinstall them?

Yes, absolutely! Always apply a light coat of grease to the pedal threads before reinstalling them. This prevents them from seizing up in the future, making them much easier to remove next time you need to. It also helps them thread in smoothly.

What happens if I try to remove the pedals in the wrong direction?

Attempting to remove pedals in the wrong direction can damage the threads on both the pedal spindle and your crank arms. If you turn the right pedal clockwise or the left pedal counter-clockwise, you’ll likely just be tightening them further, making them harder to remove and potentially causing costly damage.
