To change the inner tube or tire, you will need to remove both pedals

Use a 4mm Allen/Hex wrench to loosen the screw in the pedal hanger pillar. You will need to remove it to apply Loctite prior to reassembly. Turn counterclockwise to loosen.

Use a 5mm Allen/Hex wrench to remove the two screws that capture the hinge pin. Turn counterclockwise to loosen.

One of the screws was difficult to turn. I slipped the handle of a "four-way screwdriver" over an Allen wrench for comfort and leverage.

Avoid causing tool scaring on the end of the hinge pin. The pedals are held folded by a Teflon surface compressed against the end of the hinge pin.

Insert a hex wrench at one end of the pedal to push the hinge pin out far enough that you can pull the pin out by hand.

(in the photo, you are noticing that I taped some baby-proofing to the underside of the pedal)
