Once you have bought your new pedals, the first step to installing them is removing the old ones. Use a pedal hex or wrench to unscrew the old ones from your crank arms. Once done, we recommend reading the manufacturer's manual. But in case your pair didn’t come with a manual, start by cleaning your arms with alcohol.
You should then apply bike grease to your new pedals to avoid friction. Look at whether they are labeled L and R. L means that the pedal belongs to the left side while R is the right side. The left and right-hand pedals are different. If you install them in the wrong positions, they will not fit appropriately.
Insert each pedal to where it belongs at right angles. Place your range or hex into the ports found in each crank arm. Tighten the left one counterclockwise and the right clockwise. Tighten the pedals until they are appropriately secured. Enjoy your ride.
