How do I remove the pedal arm from a bike?

To remove the pedal arm from a bike, you will need a pedal wrench or an Allen key. First, locate the pedal on the side you want to remove. Use the wrench or Allen key to turn the pedal in a counterclockwise direction to loosen it. Once it is loose, continue turning until the pedal comes off completely. Repeat the same steps for the other pedal if needed.
