Removing and fitting bike pedals may seem like a small task, but doing it correctly is crucial to avoid damaging your bike or injuring yourself. This guide will walk you through the process step-by-step using tips and best practices.

Tools You’ll Need
- A pedal spanner (or 15 mm wrench)
- Optional: Grease for pedal threads
Understanding Pedal Threads
Pedals have different threading for each side of the bike. We will use 'left' and 'right' designations in reference to someone facing forwards on the bike. The pedal threads are as follows:
- The right pedal has standard right-hand threads and tightens clockwise.
- The left pedal has left-hand threads and tightens counterclockwise.
Tip: An easy way to remember this is that both pedals tighten when rotated towards the front of the bike, as if the pedals are mimicking wheels turning forward.
Part 1: Removing Bike Pedals
Position Your Bike:
- Place the bike upright or rest it securely on a bike stand.
- You can also lay the bike on its side if necessary.
Loosen the Pedals:
- Place the pedal spanner on the flat part of the pedal axle.
- Turn the right pedal counterclockwise to loosen.
- Turn the left pedal clockwise to loosen.
- If the pedals are difficult to loosen, apply steady pressure and ensure the wrench is firmly seated to prevent slipping.
Remove the Pedals:
- Once loose, continue rotating by hand until the pedal comes off completely.
Part 2: Fitting Bike Pedals
Apply Grease (Optional):
- Apply a thin layer of grease to the pedal threads to prevent seizing and make future removal easier.
Align the Pedals:
- Often pedals will be marked with an "R" for right, and "L" for left. If so, position the pedal marked "R" to the right crank arm and the pedal marked "L" to the left crank arm. If your pedals are not marked, remember that the right pedal uses standard right-hand threads (tightens clockwise), and the left pedal uses left-hand threads (tightens counterclockwise).
- Gently thread each pedal by hand to avoid cross-threading.
Tighten the Pedals:
- Tighten the right pedal clockwise.
- Tighten the left pedal counterclockwise.
- Use the pedal spanner to fully secure each pedal to the recommended torque (typically 39-44 Nm). If you don't have a torque wrench, consider this very firm hand pressure using the wrench or pedal spanner.
- Remember the tip: rotate both pedals towards the front of the bike to tighten.
Test the Pedals:
- Spin each pedal to ensure smooth rotation.
- Verify that the pedals are securely fastened and do not wobble.
Common Issues and Tips
- Cross-threading: If the pedal feels stuck after a few turns, stop and realign it. Forcing it may damage the threads.
- Stubborn Pedals: If a pedal is stuck, use penetrating oil and give it a few minutes to work before trying again.
- Check Orientation: Remember that the left pedal's reversed threading can cause confusion. Double-check markings to ensure proper installation.
Conclusion
By following these steps, you can safely remove and fit pedals without damaging your bike or struggling with stubborn components. Properly maintained pedals improve your cycling experience and ensure safe rides.
