I tried to replace my child because the pedal was broken because I tried it many times, but with the wrench for bicycle maintenance it was not possible to remove the pedals and it was not possible to remove the pedals. I tried shaking the CRC before using this pedal wrench, but I went smoothly. As long as the length of the handle is not long it will not come off without applying force. By the way, although it is the direction of the screw of the pedal, the left and right sides of the pedal are L (lift) with the left foot and the right one is R (right). When turning in the front wheel direction, the screws are tightened, Turn the screw in the direction to loosen the screw.
