How To Replace A Bike Pedal (Easiest Method)

by Wheels Surfer

Bike pedals are one of those parts in your ride that can easily be replaced with some simple tools. Although the process is simple enough it is recommended that you proceed with cautions since this is the part where your bike takes loads from your feet and may harm your cycling if not attached properly.

Bike Pedal Parts

Bike pedals are attached with a metal rod called the spindle. The spindle is threaded with another metal arm called the crank arm. There is a small visible, metal portion of the spindle between the pedal and the crank arm where one can place wrench jaws. However, there are other types of pedals where this portion is not for wrench usage and has an Allen-key socket at the end of the spindle.

When Do You Need To Replace A Pedal?

Typically pedals do not require much servicing like the chains or brakes. But however, after rough usages over time they might need replacements due to the fact that they bear loads from your feet. There could be three possible reasons.

  • If they are stuck or clunking while you try to turn them, probably you need to replace them.
  • If they are broken, you definitely need to replace them
  • If you need to upgrade them for better performance then you might consider replacing them.

Necessary Tools

1. Wrenches

A wrench is a common tool for repairing or assembling bike parts. For this job, you’ll require one of these three wrenches. a) Allen-key wrench. You’ll need a 6 mm one. b) Pedal spanner of 14 mm size for adult bikes. c) Pedal spanner 15 mm for kids’ bikes. Tip: Check the axel (the metal rod that is attached with your pedal and screwed with your bike’s crank arm) for the kind of wrench you’ll need. Check the end of the axel if it has any socket for Allen keys. If it doesn’t have any socket then you’ll need a pedal spanner.

2. Waterproof Grease 

Waterproof grease is used for coating metal surfaces for both clear friction generation and coating. Here we will use this to make coating inside crank-arm holes and threads.

3. Piece Of Clothing 

Any piece of old clothes will do the job. This is for wiping any dirt and cleaning the surface portions of the parts while working.

Step By Step Guide

1. Keep The Bike Standing.

Place the bike using the kickstand on any flat surface. If it doesn’t have any kickstand, support it up against a wall, a pillar, or even a table to keep it standing.

2. Wipe The Surface.

Since the pedal is used with the foot it collects lots of dust and dirt easily. Find out the portion of the axel where the wrench fits in. Clean it with a piece of clothing. 

3. Place The Wrench.

If you’re using an Allen wrench, fit the hexagonal end of the wrench into the Allen-key socket on the end of your pedal axle. In the case of pedal spanner or wrench, fit the spanner jaws around the flats between the pedal and the crank arm.

4. Hold Onto The Opposite Pedal.

This step is to give you leverage for rotating the wrench.

5. Rotate The Wrench.

Rotate it clockwise to loosen the left pedal. When using a pedal wrench, lift the wrench off the flats after a half rotation and place it again to give another half rotation. Repeat the process until the axel is fully loosened. In the case of an Allen-key, the socket will be inside of the pedal spindle. So, rotate the Allen wrench counterclockwise.

For the right padel do the exact opposite of your left pedal and rotate counterclockwise for the pedal wrench and clockwise for Allen-wrench.

6. Take Off The Pedals Carefully.

If you think the pedals are in good conditions then store them securely for future usage.

7. Wipe Inside The Axle Hole.

Use a piece of clothing with your finger and carefully clean inside the crank arm’s hole for the pedal.

8. Thinly Coat The Threads Using Waterproof Grease.

This coating will help you get your pedals off easily in the future and will also help to screw the threads nicely.

9. Place The Threaded End Of The New Pedal Into The Pedal Hole.

The right pedal usually has a small “R” on it and the left pedal has a small “L”.

10. Do A Few Turns By Hand.

This is to secure the alignment of the new pedals with the threads.

11. Place The Wrench.

When using Allen-key, put the hexagonal end through the pedal hole, into the Allen-key socket. In the case of a pedal wrench, place the jaws of the spanner around the wrench flats on the new pedal.

12. Rotate The Wrench Correctly.

Rotate it clockwise for the right pedal and counterclockwise for the left pedal. Repeat rotating the wrench until it’s properly tightened. When using a pedal wrench, lift the wrench off the flats after a half rotation and place it again to give another half rotation.


  • While installing or removing carefully rotate the wrench depending on the pedal and the type of wrench you are using.
  • Don’t tighten too much while fitting the new pedal. This might damage the thread or the hole.
  • Check your pedals by turning the bearings. Typically they take some time to move freely.
  • To check the attachments try to shake them a bit and notice if they’re loose or not. Tighten up accordingly.


Whether you are a professional rider or just someone who’s just started riding your pedals require proper balance. Keeping that in mind you should regularly check them to find out any anomalies that might be a result of a damaged pedal. Otherwise, you might lose balance while pedaling your ride. Have a safe and happy ride!
