Your new bicycle has arrived at your doorstep. Now what?
Use a knife or scissors to carefully cut just the packing tape along the edges of the top flap. Then, pull the flaps until the staples give way. Never cut through the box, as you may cut into the bike or its parts and cause inadvertent damage. Pull out loose items first. (Checklist: Saddle & seatpost, small parts box, front wheel) Carefully lift out the bike and set to work detaching all of the foam, cardboard, and other buffer materials.
Place the seatpost into the frame and position your bike on the floor or in your bike stand with the fork facing in the correction direction (brake unit and stem facing forward).
Attaching the handlebars: remove the faceplate from the stem using the appropriately-sized allen key. Lift the handlebars up to the stem, make sure they are facing the correct direction, the stem is aligned with the center of the tyre, and that the cables are not twisted - then reattach the faceplate using your allen key, watching as you tighten to ensure an even gap between the top and the bottom meeting points.
Attaching the front wheel: you may want to flip the bike upside down if you are not using a bike stand. Insert the wheel up and into the fork until the axle meets the dropouts. If it is a quick release, tighten the axle as needed, then clamp down the handle, which should sit opposite the drivetrain side of the bike. If the wheel is not quick release, use your adjustable wrench to tighten the nuts on either side evenly until the wheel is perfectly centered.
Attaching the pedals: first, identify the Left and Right pedals individually:
Begin with the Left pedal, and using just your hands to begin, thread the attachment point COUNTER-CLOCKWISE for just a few turns, then grasp the entire pedal and begin to pedal the crank backwards. For the very last few turns, use your 15mm wrench to tighten down the pedal.
When you attach the Right pedal, you will notice that it screws in CLOCKWISE, like a standard screw.
