too slippery. Don't ride.
(15) Traffic rules must be observed while driving.
(16) If there are parked cars near you when driving, slow down to avoid colliding with
suddenly opened car doors.
(17) Regular inspection:
A. Check the tires for damage and if the tire pressure is sufficient. Inspection standard: When
riding on the bike, if the length of the tire contacting the ground exceeds 9~10cm, it needs to
be inflated.
B. To check front brake function, pull it half or two-third and if the front wheel does not
rotate everything is functional. To check the rear brake: apply weight to the foot pedal while
lifting the bike. The brake is effective when the rear wheel does not rotate.
C. Check that the quick release parts of the bike are locked in place.
D. The safety line of the handlebar riser and the saddle is required to be inserted into the
front standpipe and the inside of the frame. Confirm the tightening torque.
E. Check whether the frame and the front fork are cracked or deformed, whether the pedal
and the gear crank are deformed, whether the paint is detached or wrinkled.
F. Check whether the gear is deformed or damaged.

(25) Slow down when it is rainy or if the road surface is slippery and also when going
downhill, and increase the braking distance or get off the vehicle.
(26) The driving speed should not be too fast, otherwise the high-speed driving will make the
handlebars difficult to control and the brakes will easily fail.
(27) Applicable accessories, such as tires, inner tubes and brake shoe parts, can be
purchased at domestic bicycle accessory manufacturers and bicycle repair shops.
Appendix III. Preparation before riding:
(1) Adjustment and precautions for the saddle:

A. Adjusting the height of the saddle: Generally, when the user sits on the saddle, the pedal
is stepped on the lowermost end, and the height of the saddle when the knee can be easily
and naturally bent is the best height. The user or beginner must adjust the saddle to the
position where the toes of the feet can land when riding.
B. When using the pin type saddle clamp: Use a wrench to loosen the pin nut of the clamp
saddle tube counterclockwise to adjust the height of the saddle. After adjusting the height,
lock it clockwise.
C. When using the quick release saddle clamp: adjust the saddle height by pulling the quick
release handle (the arrow direction is locked), adjust the height and lock it clockwise. If the
quick release handle is locked and you cannot reach the normal closed position, you can
adjust the adjustment nut on the opposite side of the quick release handle until the quick
release handle can be locked to the position parallel and adjacent to the front and rear fork
legs.
D. When using the screw-type saddle clamp: Rotate the knob counterclockwise to loosen the
height adjustment of the saddle tube. After adjusting the height, lock it clockwise.
E. When using the hexagon socket pin type saddle clamp: Use a 5mm hex wrench to twist
the pin counterclockwise to adjust the saddle height. After adjusting the height, lock it
clockwise. (Note: due to the left end of the pin Adjustment will damage the saddle clamp
and related components, so it must be adjusted from the right end of the pin)
F. Front and rear position adjustment of the saddle: When riding, when the foot pedal is in
the most stressed position in the oblique front, the rider's knee center line can vertically
penetrate the center of the pedal, which is the best state of riding the bike. This is used as a
reference for saddle position adjustment. In addition, the saddle should be adjusted to a
horizontal state under normal conditions.
G. Warning sign: A safety identifier is engraved on the saddle tube. The safety sign must not
be seen when used otherwise the tube might break.
(2) Adjustment and precautions for handlebars and wheels:
A. Adjusting the height and angle of the handlebars: Generally, the height of the handlebars
when the shoulders and elbows feel relaxed and comfortable when the handlebars are held
by both hands is the best height.
Crossbars and risers of the handlebars: when viewed from the side, the handlebar should be
in a 90° angle to the riser.
B. Adjust the angle of the handlebar: first loosen the handlebar locking screw (or nut), then
adjust the angle of the handlebar, adjust and then lock the handlebar.
C. Adjusting the height of the handlebar: The height of the riser can be adjusted by rotating
the riser boom screw for 2/3 turns. (The hanger screw generally uses a 13mm wrench. If it is
a hexagonal row of hanger screws, a hex wrench is to be used) If the boom is stuck in the
riser and cannot be loosened, tap the top of the screw with a wooden hammer to loosen it.
D. Warning sign: A safety identifier is engraved on the riser. The safety sign must be buried in
the front fork standpipe and locked in the riser before use. Otherwise, if the riser is extended
for a long time, there is a risk of accidental breakage.
E. Adjustment of the wheel: The wheels can be adjusted or exchanged with a quick release
or normal nuts. The torque at the front wheel is 180-220 kgf.cm and the torque at the rear

wheel 250-350kgf.cm. Please stick to this for your safety.
(3) Adjustment of the shock absorber:
A. After the adjustment of the rear shock absorber, the rider can adjust the pounds of the
rear shock absorber according to his own weight: spring shock absorber, pneumatic shock
absorber, hydraulic shock absorber, but the pounds of the shock absorber cannot be lower
than 80% of the original pounds.
B. For the adjustment of the front shock absorber, the rider can select the lock suspension
according to the road condition, the mechanical button is rotated and locked, and the line
pull type is locked. If it is a normal spring suspension, it cannot be adjusted.
(4) The total allowable weight of the bicycle: the rider and the carrier (bicycle + rider +
carrier) cannot exceed 110KG.
(5) Since all mechanical parts of the bicycle are subjected to friction and large stress,
different materials and components are subjected to various frictional fatigue stresses. If the
component is used more than its design life, a sudden damage may cause injury to the rider.
Any crack, scratch or color change in the stressed part indicates that the component has
reached the end of its service life. Replace!
(6) The rim is part of the brake system and can be dangerous in the event of wear and tear.
Therefore, this warning should be clearly and permanently marked on the rim without
covering the tire. The rider should pay attention to this. The warning sign on the rim means
to change the rim when the rim wears to the safety line. Otherwise, the rim will burst.
(7) The lighting system and reflector needs to be installed. However, the rider needs to
understand the standard of use: the front of the bicycle is a colorless (white) reflector, the
rear is a red reflector, the pedal is amber, and the rim is colorless or amber.
Appendix IV. Adjustment and Precautions for the
Brake
（1）To check front brake function, pull it half or two-third and if the front brake does not
rotate everything is functional. To check the rear brake: apply weight to the foot pedal while
lifting the bike. The brake is effective when the rear wheel does not rotate.
（2）Avoid pinching your fingers when pulling the brakes.
（3）Brake adjustment: After long-term use, the brake cable lengthening and other factors
will make the brake effect worse. At this time, the adjustment screw on the brake lever can
be rotated to tighten the brake wire to the state where the left and right brake skins are at
the distance of 2 mm from the rim, and the adjustment nut is locked.
（4）Brake line replacement time: The normal state is 1 year replacement, but if abnormal
phenomena such as rust and break occur, it must be replaced as soon as possible.
（5）The use of the foot brake is to use the foot to step on the pedal and then pour 60
degrees, so that the sprocket drives the chain to make the rear wheel rotate again and then
the hub brakes. Pay attention to the need to lock the hub
(6) Adjustment and precautions for the brake:
A. The lever type brake is adjusted by loosening the lock nut rotation lever.
