Adjust the handlebar
The following illustrates how to adjust the handlebar and the folding grip.
Tighten the sleeve securely to the handlebar. Align
the left side of the sleeve with the handlebar stem
and tighten the stem bolt to secure the handle bar
and sleeve. NOTE: the sleeve must be tightened
before the stem for proper clamping.
The folding grip consists of copper button,
spring, and screw. By turning the screw we
can adjust the tightness.
Note: If you tighten the screw too much will make the copper button unable to
insert the handle.
