How to Unscrew Bike Pedals: A Comprehensive Guide for Cyclists

Struggling to remove those stubborn bike pedals? You’re not alone! Unscrewing bike pedals can be a surprisingly tricky task, often requiring the right tools, techniques, and a bit of know-how. This comprehensive guide will walk you through the entire process, from understanding pedal threads and choosing the correct tools to mastering the best techniques for removing even the most seized-up pedals. We’ll cover common pitfalls and provide expert tips to ensure a smooth and successful pedal removal, saving you time, frustration, and potential damage to your bike. Our years of experience working on bicycles have taught us the importance of proper technique, and we’re here to share that knowledge with you.

Understanding Bike Pedal Threads and Direction

Before you even think about reaching for a wrench, it’s crucial to understand how bike pedal threads work. This is the single most common source of frustration and stripped threads. Bike pedals are threaded differently on each side of the bike. This is to prevent them from unscrewing themselves while you’re pedaling.

• Right Pedal (Drive Side): This pedal has a standard right-hand thread. This means you loosen it by turning it counter-clockwise when facing the pedal from the outside.
• Left Pedal (Non-Drive Side): This pedal has a left-hand thread (also known as a reverse thread). You loosen it by turning it clockwise when facing the pedal from the outside.

Remember the phrase “Righty Tighty, Lefty Loosey” only applies to the right pedal. For the left pedal, it’s the opposite. Many pedals are marked with an “L” or “R” to indicate which side they belong to. If you’re unsure, double-check before applying force. Trying to unscrew a pedal in the wrong direction is a surefire way to damage the threads.

Why Are Pedal Threads Different?

This seemingly counterintuitive design is a clever solution to a common problem. As you pedal, the force applied to the pedals can create a loosening effect. By using opposite threads, the pedals are effectively self-tightening. Without this design, pedals would constantly be working themselves loose, leading to a potentially dangerous situation.

Gathering the Right Tools for the Job

Having the right tools is essential for successfully unscrewing bike pedals without damaging them or yourself. Here’s a list of the tools you’ll need:

• Pedal Wrench: A pedal wrench is specifically designed for removing bike pedals. It’s usually 15mm and longer than a standard wrench, providing extra leverage.
• Allen Wrench (Hex Key): Some pedals have a hex key socket on the inside of the crank arm. Check your pedals to see if this is an option. Common sizes are 6mm or 8mm.
• Crank Arm Protection: Using a piece of cardboard or cloth can protect your crank arms from scratches during the removal process.
• Penetrating Oil (Optional): If your pedals are stuck, penetrating oil can help to loosen them. WD-40 Specialist Penetrant or similar products work well.
• Hammer (Optional): A rubber mallet can be used to gently tap the wrench to help break the pedals free.
• Work Gloves: Protect your hands from sharp edges and provide a better grip.

While a standard wrench can sometimes work, a pedal wrench is highly recommended. Its length provides the necessary leverage, and its thin profile allows it to fit easily between the pedal and the crank arm. Using the wrong tool can lead to damaged pedals, crank arms, or even injury.

Step-by-Step Guide: How to Unscrew Bike Pedals

Now that you understand the threads and have the right tools, let’s get to the actual process of unscrewing the bike pedals. Follow these steps carefully:

1. Prepare Your Bike: Secure your bike in a repair stand or lean it against a stable surface. Make sure the crank arms are horizontal. This position provides the best leverage.
2. Identify the Correct Direction: Remember, the right pedal loosens counter-clockwise, and the left pedal loosens clockwise (when facing the pedal from the outside).
3. Position the Wrench: Place the pedal wrench on the pedal axle, ensuring it’s fully engaged. If using an Allen wrench, insert it into the hex key socket.
4. Apply Pressure: Apply firm, steady pressure to the wrench. Avoid jerking or sudden movements, as this can strip the threads.
5. If Stuck, Use Penetrating Oil: If the pedal is stuck, spray penetrating oil around the pedal axle where it meets the crank arm. Let it sit for 10-15 minutes to allow the oil to work its way into the threads.
6. Tap the Wrench (Optional): If the penetrating oil doesn’t work, gently tap the end of the wrench with a rubber mallet. This can help to break the corrosion or gunk that’s holding the pedal in place.
7. Unscrew the Pedal: Once the pedal starts to move, continue unscrewing it until it’s completely removed.
8. Repeat on the Other Side: Repeat the process on the other pedal, remembering to reverse the direction.

Troubleshooting Stuck Pedals

Sometimes, even with the right tools and techniques, pedals can be incredibly stubborn. Here are some additional tips for dealing with stuck pedals:

• More Penetrating Oil: Don’t be afraid to apply more penetrating oil and let it sit for a longer period, even overnight.
• Heat: Applying heat to the crank arm (around the pedal axle) can help to expand the metal and loosen the threads. Use a heat gun or hair dryer, and be careful not to overheat the crank arm.
• Longer Wrench: If you’re still struggling, try using a longer wrench for even more leverage. You can sometimes slide a pipe over the end of your existing wrench to extend its length.
• Professional Help: If all else fails, take your bike to a professional bike mechanic. They have specialized tools and experience in dealing with stubborn pedals.

Preventing Pedal Seizure: Proper Installation and Maintenance

The best way to avoid struggling with stuck pedals is to prevent them from seizing up in the first place. Here’s how:

• Grease the Threads: Always apply a generous amount of grease to the pedal threads before installing them. This will prevent corrosion and make removal much easier in the future.
• Tighten Properly: Tighten the pedals securely, but don’t overtighten them. Use a torque wrench if you have one, and follow the manufacturer’s specifications.
• Regular Inspection: Periodically inspect your pedals to make sure they’re still tight and haven’t started to loosen.
• Clean and Lubricate: Clean your pedals regularly and apply a light lubricant to the moving parts.

By following these simple steps, you can significantly reduce the chances of your pedals becoming stuck and avoid the frustration of struggling to remove them.
