HOW TO INSTALL THE PEDALS: The pedal threads differ between the left and right side. L / R marks are embossed on the spindle of each pedal, ensure they are assembled on the correct side (when riding the bike the left pedal should be on your left hand side, right pedal on right hand side). The right pedal has a right-hand thread (removes counterclockwise, installs clockwise). The left pedal has a left-hand thread (removes clockwise, installs counterclockwise).
