Article: First, identify which is which by checking the spindles. Find the L and R markers respectively. Use the L pedal on the bike’s left side and the R pedal on its right (which would be your left and right when seated on the bike). To attach them:  Screw each pedal onto its corresponding thread with your hands at first (turning clockwise for the right pedal and counterclockwise for the left). Then switch to a wrench to tighten them firmly into place as you near the end. If your bike has gears, raise the back tire off the ground. Turn the pedals and shift through all the gears as you do. Make sure each one shifts to the next smoothly. If they don’t, set the bike to its highest gear before making your adjustments. Locate the brake pads. Keep your eyes on these as you turn your pedals. Squeeze the brake lever and make sure that:   The brake pads make contact on the rim without interference. The brakes should rest squarely on the rim and should not rub on the tire itself when they are engaged. They do so when the brake lever is only a third of the way to making contact with the handlebar. Each pad retreats the same distance from the rim when you let go of the lever. First, make sure any gear or brake levers are in front of your handlebar, at a 45° angle between the bar and the ground. Squeeze them to make sure they’re working properly. Then set both wheels on level ground. Check the angles of both the front and back reflectors. If necessary, adjust them so they’re at least within 5 degrees of being perfectly vertical with the ground.  At this point, you should be done assembling. However, inspect your handiwork step-by-step before using your bike. Make sure that you haven’t overlooked anything or made any mistakes.
