Remove the protective plastic cap from the end of the handle bar
assembly, and insert the two pieces at the end of the stem into the headset
bearing as shown above. There is a maximum installed height etched into the
stem- pick a height within the allowed range and tighten the jam nut using your
M6 hex wrench. Install the Seat.
If you do not have a bicycle assembly stand, at this point you can turn
the bike upside down so that it rests on the seat and handlebar. If you do have
a stand, mount the bike now.
