Before You Ride
·If this is your child’s first time of cycling, parents or guardian,should instruct your child how
to correctly use the bike and warn your child about relevant attentions, particularly in the safe
use of the braking systems.
·Please avoid riding under severe environment.
·Please avoid riding during night.
·Please increase braking distance in case of raining and freezing.
·Please check the condition of your bike, especially for the brake, on a regular basis according
to the information in the Table of Maintenance and Cleaning.
·Please repair your bike according to the descriptions in this manual when the breakdown
occurs. If the problem cannot be settled yet, please resort to professionals. Children are strictly
forbidden to repair bikes.
·For your safety of riding, please select original accessories. If the front fork needs to be
replaced, the set-back and inner diameter of the new one should be consistent to the original
one.
Before every ride, it is important to carry out the following safety checks:
1.Ensure the handlebar and saddle height is appropriate to the needs of the riding.
2.Ensure all components are assembled in place and screwed tightly. If any components
loosen, please screw tightly before using.
3.Ensure the front and rear brakes work properly.
4.Ensure both ends of the handlebar are properly protected.
5.Ensure tires are inflated to the pressure indicated on the tire sidewall.
6.Check that the tires shows no signs of excessive wear or flat spots, and that there are no cuts
or other damage. Excessively worn or damaged tires should be replaced.
7.Ensure the chain work properly. The chain needs to be adjusted when loosens, in case of
falling off during cycling.
8.Ensure all accessories are assembled firmly and work properly.
Adjustment and Maintenance
Refer to the content of brake adjustment and maintenance in this manual and videos on brake
adjustment.
1. Saddle Adjustment
If the saddle height needs to be adjusted, unscrew the bolt of quick release（a） first, and then
place the end of seat pillar in the tube in the frame, set the required height and lock the bolt of
quick release（a）.(Tightness of the quick release bolt（a） can be adjusted by rotating the quick
release lever(b). Please check and screw the bolt under the saddle tightly in order to ensure
safety.) （As shown in figure ）
Warning：Safe Sizing For Juvenile And Sidewalk Bicycles-It is assumed that the bicycle you
have bought is sized correctly for the user. Some parents make the mistake of buying a bicycle
too large for the intended rider, planning on the child “growing into” it. There should be a
minimum of 1 inch clearance above the highest point of the top tube when the child is
straddling the bicycle with both feet on the ground( see drawing below).
2. Stem Assembly and Adjustment
(1) If the expander bolt cannot be screwed tightly, please take out the stem and check if the
bottom wedge(c) (metal pieces of castings) falls into the head tube.If it happens, please pour
out the wedge(c) from the head tube and then screw it to the expander bolt and insert into the
head tube again when the distance to the bevel connection of the stem is 2-3mm.Then use the
spanner T1 to screw the stem tightly in clockwise direction. The handlebar should be adjusted
to be vertical with the front wheel before screwing.（As shown in figure ）
(2)How to settle the problem that the handlebar is not flexible or too flexible when turned left
and right?
Screw to loosen the head lock nut(d) counter clockwise direction by using adjustable wrenche,
and slightly screw to loosen the top head race(e) counter clockwise direction (or screw to
tighten in clockwise direction) to test the tightness when turning the handlebar. Repeat the
steps if necessary until the tightness is appropriate and finally screw the head lock nut(d) tightly.
（As shown in figure ）
3. Using and Adjusting the Brake
The left brake lever controls the rear brake, and the right brake lever controls the front brake.
(1)Adjustment of Caliper Brake
If the clearance of both sides of the brake block are too far or too close to the rim, loosen the
cable adjustment screw(h) fixing the cable end. Then use one hand to press the two brake block
to the right posiotion and pull the brake cable to its tension. Tighten the brake cable adjustment
screw(h). Test the brake. Do the adjustment again if necessary, until the brake works well. On the
occasion that one side of the clearance of brake block is smaller than that of the other side,
tighten the brake fixing nut(i) on the rear side of the front fork bellow the head tube of the frame
to make the brake block to the right position. Test the brake lever to see the effect. Tighten the
bolt again or slightly loosen the bolt if necessary until the clearance of the two brake block are
same. （As shown in figure ）
(2) Adjustment of Band Brake
If the rear wheel can still rotate when the brake lever is held tightly, firstly use the spanner to
screw the adjusting nut of brake cable tightly, and then test the flexibility of the brake. If the
brake is still not so flexible, use the screwdriver to loosen the cable adjustment screw (k), and
then tighten the brake cable and the cable adjustment screw(k) at the same time. After that,
release you hands and test the flexibility of the brake again. In order to get the optimum status,
adjust it repeatedly to ensure a suitable length of the exposed brake cable.
Since the working principle of the brake is to restrain the rotation of the wheels by drag force
due to friction, the brake block may be worn out after a period of using, thus the brake would
not be so flexible. Under such condition, adjusting nut of the brake block (l) should be adjusted
by screwdriver. The brake would be more flexible if you screw it more tightly. However, the brake
block should not hold the brake drum when it is not braked. (See figure )

4. Correct Method of Adjusting the Tension of the Chain
The adjustment nut for chain is assembled on the rear fork end, and the tension of the chain can
be adjusted by loosening or tightening such nut.
5. Bolts and Nuts Torque Checklist
Mind to check if all bolts and nuts in the bike are firmly tightened on a regular basis. You are
suggested to tighten the bolts and nuts on relevant positions by torque wrench according to the
torque data in the following table.
Special Declaration
