Instructions
Turn the black knob near the base of the handlebar assembly clockwise to loosen the handlebar folding mechanism. Pivot the knob forward.
Fold the handlebar assembly to the side, exposing the stem bolt atop the PowerWing head tube.
Turn the stem bolt counterclockwise until loose. The bolt requires a 5 mm hexagonal wrench.
Raise or lower the stem connecting the handlebar assembly to the head tube. Adjust the height.
Check that the black knob is in line with the front wheel. Use the 5 mm hexagonal wrench to tighten the stem bolt. Tighten the bolt enough to allow the handlebar and front wheel to pivot together. A loose bolt will cause the the handlebar and wheel to go out of alignment.
Raise the handlebar assembly to its upright position.
Pivot the black knob upright. Turn the knob clockwise to secure the adjustment.
