A pair of foldable pedals. By pushing in these pedals to fold them, you can save instantly on storage of shipping space. The pedal size is 9/16 inch. These pedals fit our Columba bikes with 20-inch or 26-inch wheels.
To measure the pedal size of your own bike, you can unscrew the left pedal from the crank arm. (Remember, the left pedal is the one with the left-hand thread.) Turn your wrench clockwise to take the left pedal off from the crank. Then, measure the diameter of the threaded end with a vernier caliper. Your bike pedal size wil be either 9/16" (14.3 mm) or 1/2" (12.7 mm). Most bikes have 9/16-inch pedals.
