How do I properly assemble a bike pedal assembly?

To properly assemble a bike pedal assembly, first, ensure you have the correct tools such as a pedal wrench. Next, apply grease to the pedal threads and screw them into the crank arms by turning them clockwise. Use the pedal wrench to tighten them securely, making sure they are aligned correctly. Repeat the process for the other pedal, remembering that the left pedal has reverse threads. Double-check the tightness before riding to prevent any issues.
