Removing bicycle pedals requires the correct tools, understanding pedal threading, and applying proper technique to avoid damage.
Understanding Bicycle Pedal Mechanics
Removing pedals from a bicycle might seem straightforward, but it involves nuances that can trip up even seasoned cyclists. Every pedal is threaded differently on each side to prevent them from loosening during rides. The right pedal features a standard right-hand thread (tightens clockwise, loosens counterclockwise), while the left pedal has a reverse or left-hand thread (tightens counterclockwise, loosens clockwise). This design ensures pedals stay firmly attached under pressure.
Knowing this is crucial because attempting to unscrew pedals without this knowledge can lead to stripped threads or damaged cranks. Most modern bicycles use either 9/16-inch or 1/2-inch pedal spindles, dictating the size of the wrench or tool needed. Older or specialized bikes might have different sizes, so identifying your pedal type beforehand saves time and frustration.
Right vs. Left Pedal Threading
The right pedal screws in clockwise and unscrews counterclockwise. Conversely, the left pedal screws in counterclockwise and unscrews clockwise. This counterintuitive setup is designed to prevent pedals from loosening due to the rider’s pedaling motion.
If you try to remove the left pedal by turning it counterclockwise (as you would for bolts), you’ll only tighten it further. This is a common mistake and often causes stripped threads or broken tools. Always remember:
- Right pedal: loosen by turning left (counterclockwise)
- Left pedal: loosen by turning right (clockwise)
Essential Tools for Removing Bicycle Pedals
Before diving into how to remove the pedals from a bicycle, gather the right tools. The job is much easier with proper equipment:
- Pedal wrench: A thin, long-handled wrench designed specifically for pedals; usually 15mm.
- Adjustable wrench: Useful if you don’t have a pedal wrench but less ideal due to thickness.
- Hex key (Allen wrench): Many modern pedals require an 8mm or 6mm hex key inserted into the back of the crank arm.
- Lubricant or penetrating oil: WD-40 or similar helps loosen stubborn or rusted pedals.
Pedal wrenches are preferred because they fit snugly on flat surfaces of pedal spindles and provide excellent leverage without damaging components. Hex keys work well on many newer bikes but require access behind the crank arm.
Choosing Between Pedal Wrench and Hex Key
If your bike’s pedals have flat surfaces on the spindle near where they attach to cranks, a pedal wrench is your go-to tool. It offers more torque and reduces slippage risk.
For pedals with hex key sockets inside the crank arm hole, using an Allen wrench is cleaner and sometimes easier in tight spaces. However, applying enough force with a hex key can be tricky without stripping bolts if not careful.
The Step-by-Step Process: How To Remove The Pedals From A Bicycle
Step 1: Position Your Bike Securely
Place your bike on a stable surface such as a repair stand or lean it securely against a wall. If you don’t have a stand, flip the bike upside down resting on handlebars and seat for better access.
Make sure there’s enough room around you to work safely without bumping into objects.
Step 2: Identify Left and Right Pedals
Look closely at each crank arm near the pedal attachment point; most manufacturers mark “L” for left and “R” for right somewhere visible.
Remember:
- The right pedal loosens by turning counterclockwise.
- The left pedal loosens by turning clockwise.
This step alone prevents costly mistakes.
Step 3: Apply Penetrating Oil If Needed
If pedals haven’t been removed in years or feel stuck, spray some penetrating oil at the junction between spindle and crank arm threads. Let it sit for about five minutes to seep in.
This softens rust and grime buildup that could otherwise make removal difficult.
Step 4: Position Your Wrench Correctly
Place your pedal wrench flat against the narrow flats on the spindle closest to where it meets the crank arm. For hex keys, insert into the back of each crank arm’s hole until fully seated.
Make sure your tool is firmly engaged before applying force; slipping can damage parts or cause injury.
Step 5: Apply Steady Force in Correct Direction
For each side:
| Pedal Side | Tightening Direction | Loosening Direction (Removal) |
|---|---|---|
| Right Pedal (Drive Side) | Clockwise (right) | Counterclockwise (left) |
| Left Pedal (Non-Drive Side) | Counterclockwise (left) | Clockwise (right) |
Push or pull your wrench steadily rather than jerking motions; sudden force risks stripping threads.
If stuck tight, try rocking gently back-and-forth while applying penetrating oil again if necessary.
Troubleshooting Stubborn Pedals
Sometimes pedals refuse to budge despite all efforts. Here are some tips:
- Add leverage: Use a longer wrench handle or attach a pipe over your wrench handle for extra torque—but be cautious not to damage your tools.
- Tapping method: Lightly tap around spindle-crank interface with a rubber mallet after oiling; vibrations can help loosen corrosion.
- Heat application: Carefully heating aluminum crank arms near threading area with a heat gun can expand metal slightly—avoid overheating plastic parts.
- Screwdriver assistance:If using hex keys inside crank arms, ensure bolts aren’t stripped; replace if damaged before retrying removal.
Avoid forcing too hard without progress because this could ruin threads permanently requiring costly repairs.
Caring for Your Cranks After Pedal Removal
Once pedals come off cleanly:
- Inspect threads:If threads show signs of wear or damage like cross-threading or corrosion, clean them thoroughly with a wire brush.
- Add grease:Smoothly coat spindle threads with high-quality bike grease before reinstalling new pedals—this prevents seizing in future removals.
- Tighten properly:Tighten new pedals firmly but don’t overtighten; use manufacturer torque specs if available.
- Clean components:A quick wipe-down removes dirt buildup that could affect performance later on.
Good maintenance habits extend component life significantly.
The Role of Pedal Types in Removal Techniques
Not all pedals are created equal—some designs influence how easy they are to remove:
- Cage-style pedals: Traditional platform pedals with cages usually have standard threaded spindles accessible by wrenches easily.
- Bearing cartridge pedals: Higher-end models often sealed bearing units requiring specific tools but generally follow same threading rules.
- BMX-style pins:BMX flat pedals sometimes use different sizes like smaller spindles needing smaller wrenches or Allen keys.
- Lace-up clipless systems:The actual clipless mechanism doesn’t affect removal since you only deal with spindle threads—but extra care needed not to damage cleats when handling cranks.
Knowing your specific setup helps choose correct tools upfront saving hassle mid-job.
A Handy Comparison Table of Common Pedal Sizes & Tools Needed
| Bicycle Type | Pedal Spindle Size | Main Tool Required |
|---|---|---|
| Mature Road Bikes / Mountain Bikes | 9/16 inch (14 mm) | 15 mm Pedal Wrench / 8 mm Hex Key |
| Kiddie / Older Bikes / BMX Entry Level Models | 1/2 inch (12.7 mm) | 14 mm Wrench / Adjustable Wrench / Hex Key Depending on Model |
| Cruisers / Vintage Bikes | Might vary – check markings | Crescent Wrench / Adjustable Wrench + Penetrating Oil Recommended |
| Synthetic Composite Spindles / Specialized Models | N/A – Check Manufacturer Specs | User Manual Recommended / Specialized Tools Possible |
This quick guide helps identify what fits best before starting removal work.
Avoiding Common Mistakes When Removing Bicycle Pedals
Several pitfalls can complicate how to remove the pedals from a bicycle:
- Avoid trying to loosen both sides using same rotation direction—remember reversed threading on left side!
- DON’T use pliers unless absolutely necessary; they often slip causing scratches and damage.
- Avoid forcing excessive torque without lubrication—it leads to permanent thread damage requiring professional repair.
- DON’T neglect cleaning old grease/dirt before re-greasing new installations—this reduces efficiency long-term.
- Avoid removing pedals without stabilizing bike properly; unstable setups increase injury risk during force application.
Being mindful prevents unnecessary headaches during what should be routine maintenance.

Frequently Asked Questions
How to Remove the Right Pedal from a Bicycle?
The right pedal has a standard right-hand thread, meaning it tightens clockwise and loosens counterclockwise. To remove it, turn the pedal spindle to the left (counterclockwise) using a pedal wrench or hex key. Applying lubricant can help loosen stubborn pedals.
How to Remove the Left Pedal from a Bicycle?
The left pedal uses a reverse thread, tightening counterclockwise and loosening clockwise. To remove it, turn the spindle to the right (clockwise). This is opposite to most bolts, so be careful not to tighten it accidentally while trying to remove it.
What Tools Are Needed to Remove Bicycle Pedals?
A pedal wrench (usually 15mm) is ideal for removing pedals due to its thin profile and leverage. Alternatively, an adjustable wrench or an 8mm or 6mm hex key may be used depending on your bike’s pedal type. Lubricant can assist with stuck pedals.
How Does Pedal Threading Affect Removing Bicycle Pedals?
Pedal threading prevents pedals from loosening during rides by having opposite threads on each side. The right pedal tightens clockwise; the left tightens counterclockwise. Knowing this prevents damage like stripped threads when removing pedals.
What Should I Do If My Bicycle Pedals Are Stuck?
If pedals are difficult to remove, apply penetrating oil or lubricant and let it sit for several minutes. Using a proper pedal wrench with steady force helps avoid damage. Avoid excessive force that could strip threads or break tools.
