vehicle according to the following steps.
5.1 handlebar mount
5.1.1 First fold the folding riser, lock the folding handle, and fasten the safety
hook.
5.1.2Align the stem so that the handlebars are inserted at a 90-degree angle to the
folding stem, deeper than the highest safety line on the stem, then lock the quick
release handle on the folding stem.
5.1.3Adjust the handlebar to the correct position, then lock the quick release
handle on the riser.

5.2Front wheel installation
Make sure the front and
rear wheels are in line, then
start the installation. Pull
the wheel up first and place
the disc brake pads into the
front brake calipers.
Insert the quick release
lever into the shaft and lock
it. The handle of the quick
release lever is on the other
side of the disc.
5

5.3 lamp installation
Tighten the screws with an Allen
key and wrench.
Prepare the front fender
and remove the headlight
screw.
Put the headlight bracket and
fender bracket into the screws
and align them.
6

5.4 pedal installation
R L
Gently screw the left pedal
onto the left crank by hand,
turning it counterclockwise.
Then use a 15# open-end
wrench to tighten the pedal.
Check the chain. Rotate the
right pedal and crank toward
the rear of the bike as if you
were pedaling backwards.
Watch the chain to make sure
it runs smoothly through the
drivetrain (around the rear
cog, chain tensioner and front
chainring).
Find the right/left pedals
marked "R", "L", there should
be "R" "L" labels.
Gently screw the right pedal
onto the right crank by hand,
turning it clockwise. Then use
a 15# open-end wrench to
tighten the pedal.
7

5.5 Cushion installation
It is important to position the seat at the correct height for better pedaling, safety and
overall ride comfort. The length of the rider's legs is used to determine the seat position.
Your hips should be level as you pedal, and your legs should be almost fully extended
at the bottom of the pedal, but not hyperextended. To determine the correct seat for him,
sit on the e-bike with one pedal at its lowest point and put your foot on the ball on the
pedal. Your legs should be almost fully extended (not locked out) with a slight bend at
the knees.
Adjust the seat and seat head
so that they are parallel to the
top tube.
Close the quick release lever
with your palm or fingers.
Open the quick-release
lever fully and swing it out
to open the quick-release
lever.
Move the seat up and down
by sliding the seatpost in or
out of the seat tube. Do not
raise the seatpost past the
minimum insertion mark
etched on the seatpost tube!

right shift lever, the rear derailleur will move from the inside to the outside, and at the
same time, the chain will move from the large piece of the flywheel to the small piece
position, which will increase the speed of riding and also increase the riding speed. The
pedaling force of the row is adjusted to realize the shifting process of the rear
derailleur.

tighten the nuts on both sides. . If the chain is too tight, do the reverse operation
according to the above method. The chain is tight and tight (sag 10mm-15mm)
8.3.1.4 When adjusting the height of the handlebar, pay attention that the safety
line on the main tube should not be exposed. And note that the tightening torque of the
core screw is not less than 18N. m. The tightening bolt torque of the cross bar is not less
than 18N. m.
8.3.1.5 When adjusting the height of the saddle, pay attention that the safety
wire on the saddle should not be exposed, and pay attention that the tightening torque
of the saddle nut and the saddle tube clamping bolt is not less than 18N.m.
