9 Ways To Fix Bike Pedal Won’t Screw In  

Say goodbye to frustrations resulting from a bike pedal that won’t screw.

These tips will help you fix it :

1. Place Your Bike on A Flat Surface 

To prevent your bike from tumbling and damaging the screws and the new pedal while trying to fix it, you need to keep it on level ground.

2. Identify the Right Tools

To remove old pedals, you’ll need the proper wrench. If the pedal is connected to the crank arm by a flat type of nut, you typically need a 15-millimeter spanner. 

However, if the socket is hexagonal, you will need an Allen key wrench.

3. Use the Wrench to Remove the Pedal

Attach the wrench to the Allen key socket or spanner flats, starting with the right-hand pedal, and rotate counterclockwise to release the right pedal.

To loosen the left-hand pedal, you must turn in the opposite direction.

4. Apply Grease to Bike Threads

You must lightly spray the metal threads inside the pedal holes on the crank arm of your bicycle before installing a new pedal. 

You can buy different types of waterproof lubricants at the mechanic or bike shop. This will simplify your job of screwing on and removing the new pedals.

5. Be Sure the Pedal Socket Is Clean

When dirt and other particles find their way to the pedal socket, they make it difficult to screw. 

They may push the threads on the screws holding the pedals to your bike out of their normal position. So, it is better to clean the area thoroughly before trying to install your bike pedals.

6. Place Right Pedal into Pedal Hole

You are required to start from the right side of your bike during installation. Search the pedal for a little letter “R.” 

Then gently place the pedal’s end on the hole without pressing it. Using your hands to guide the threads onto the pedal hole would be best.

7. Use the Wrench To Screw New Pedal

When tightening the right pedal onto the bike’s crank arm, turn the wrench in a clockwise direction. 

To avoid stripping your metal threads of its new pedal, try not to force it. Instead, you can go back to repeat the previous step. 

8. Repeat Previous Step with Left Pedal

To fix the left pedal without difficulty, you need to turn it anti-clockwise to screw it. Bike riders who don’t know this fix often complain that their pedals are difficult to attach.

9. Check the Security of The Pedals 

Check to see if your pedals are securely fastened by ensuring they are not misaligned or loose on their bearings. 

A new pedal might not spin quickly, but it should be able to spin smoothly without problems or being stuck.
