How do I properly remove the left pedal from my bicycle?

To properly remove the left pedal from your bicycle, you will need a pedal wrench or a 15mm wrench. Turn the wrench counterclockwise to loosen the pedal. Once it is loose, continue turning until you can unscrew the pedal completely from the crank arm. Be sure to remember that the left pedal has reverse threading, so you will need to turn it clockwise to remove it.
