Changing Bike Pedals at Home


Changing bike pedals may seem like a daunting task, but with the right tools and a little know-how, it can be a straightforward process. In this comprehensive guide, we will walk you through the step-by-step instructions on how to fit and remove pedals from your bicycle. Whether you’re a seasoned cyclist or a beginner, this guide will provide you with the knowledge you need to confidently tackle this task.

Tools Required to Fit and Remove Pedals:

Before diving into the process, let’s familiarize ourselves with the tools necessary for fitting and removing bike pedals. In most cases, you will need either a 15mm spanner or an 8mm Allen (hex) key. These tools are readily available at most bike shops or can be purchased online. Having the right tools on hand ensures a smooth and hassle-free pedal replacement experience.

How to Tell Left from Right Pedals:

One of the first things to consider when changing bike pedals is distinguishing between the left and right pedals. To avoid confusion, take note that pedals are typically labeled “L” for the left pedal and “R” for the right pedal. In case the labeling is unclear or absent, you can determine the side by examining the threading. The left pedal has reverse (left-hand) threading, while the right pedal has standard (right-hand) threading.

How to Remove Pedals from a Bike:

Removing pedals from your bicycle requires careful attention to prevent any damage or unnecessary strain. Here’s a step-by-step process to guide you:

Prepare your bike: Find a suitable workspace and position your bike securely. You may need to use a bike stand or have a friend hold the bike steady.

Choose the correct tool: Determine whether you need a 15mm spanner or an 8mm Allen key based on the type of pedals you have.

Position the tool: Place the tool onto the pedal axle and ensure a firm grip.

Rotate counterclockwise: Remember the reverse threading on the left pedal? To remove it, turn the wrench or Allen key counterclockwise. Apply steady pressure, but avoid using excessive force to prevent damage.

Repeat for the right pedal: The right pedal follows standard threading, so rotate the tool clockwise to loosen and remove it.

How to Fit Pedals to a Bike:

Once you have successfully removed the old pedals, it’s time to fit the new ones. Follow these steps for a proper installation:

Examine the pedal threads: Before attaching the new pedals, inspect the threads on the crank arms. 

Identify the left and right pedals: Refer to the labeling or threading to determine which pedal goes on which side.


Apply grease: To prevent the pedals from seizing and to facilitate future removal, apply a thin layer of grease to the pedal threads.

Position the pedal: Align the pedal with the appropriate side, ensuring the threads engage smoothly.

Hand-tighten: Begin by turning the pedal spindle clockwise by hand. Once it’s snugly fitted, use the 15mm spanner or Allen key to fully tighten it. Be careful not to overtighten, as this may cause damage.

Repeat for the other pedal: Follow the same process for the opposite side, taking care to fit it securely without over-tightening
