HANDLEBAR ADJUSTMENT
Your bicycle’s handlebars can be adjusted up and down.
Screw stem: Your bicycle is equipped with an “immersion” stem, and you can change the height by changing the insertion of the
stem in the frame pivot tube.
To adjust the height of the handlebar, loosen the clamping screw with a 6 mm hex wrench and raise or lower the stem to the
desired height.
Be careful not to exceed the minimum insertion mark. This insertion mark should never be
visible when using the bicycle.
Tighten the immersion screw, making sure that the stem is in the correct position.

14
To adjust the tilt of the handlebar, loosen the stem screw-pivot shown
in the picture with a 5 mm hex key, select the position and tighten it.
You may then need to adjust the position of the handlebars on the stem by loosening
the screws of the stem cover, turn the handlebars at your convenience and tighten
these same screws.
Take care that the handlebars are correctly centered.

15
BRAKE ADJUSTMENT
When adjusting the brake, make sure that the brake surface contacts the brake disc tightly when the handlebar is clenched to the
middle.
If you feel the brakes are not working well, you can use the brake cable tension adjusting screw to adjust the brake stroke.
This screw is located at the brake handle (see “A”). Turn the brake cable screw inward to relax it and the brake shoe will be farther
away from the rim; turn the brake cable screw outward to tighten it and the brake shoe will be closer to the brake disc.
Contact your retailer or the after-sale-service in case of need.
1. When the braking system is too weak or too strong, use the tool to loosen the screw (C point in the picture), frap or relax
the length of cable to adjust the brake effect.

16
2. When adjusting the brake, please pay attention to brake pad and brake disc (D point) for clearance
uniformity. Keep vertical and lateral parallel distance, loose the screw to adjust (A point in the
picture). The brake must be adjusted so that it can be activated by force by 6-8N/m.

PEDAL ASSEMBLING
“L” is the left pedal, “R” is the right pedal; both of them should tight together by forward position.
SADDLE ADJUSTMENT
For the riding height, please pay attention to the distance between the seat saddle and the pedal at the lowest position.
You can adjust the seat height by loosening the seat holder pipe clamp.
When positioning the seat in its lowest position, make sure that it does not touch any components of the bicycle such as the
luggage rack.
Likewise, make sure you do not exceed the minimum insertion mark of the seat tube.
This insertion mark should never be visible when using the bicycle.

18
The riding height has been well adjusted if your knee joint can bend slightly when your foot is placed on the pedal (at the bottom).
To check the seat’s correct height, you should be sitting with straight legs and your heel on the pedal (illustration B).
When pedalling, the knee should be lightly bent with the foot pointing down (illustration A).

19
If any questions, please consult your bicycle dealer.
WARNING
It is important to protect the seat springs if installing a child seat in order to avoid the risk of getting your fingers caught.

As a safety measure, luggage must only be carried on the luggage rack.
All luggage must be firmly secured to the luggage rack before each use it is important to check that nothing is left hanging over
an edge which may become caught in the rear wheel of the bicycle.
Do not adjust the rack arbitrarily, please consult your dealer for adjustment if necessary. Do not modify the luggage rack, any
modification of the rack by the user leads to the invalidity of this user guide. The luggage should not obscure your bicycle's the
reflectors and lights.

PEDALLING POWER
The electric power system is working according to the speed of your pedalling.
The faster you are pedalling, the stronger the electric power will be within its limit speed of 25km/h; if you’re not pedalling, the
motor will stop.
The user must rotate the pedal forward to receive the motorized assistance. This is an important safety feature. This power-assisted
bicycle provides motorized assistance up to a speed of 25 km/h. Beyond that, the engine will stop. You can go faster, but you will
have to do it on your own, without any electrical assistance.
The engine will not work until you have completed a full turn of the pedal. This feature protects the motor and its controller and
extends the life of the electrical components.
More information you need to know about pedalling power:
•The starting of this bicycle is different from that of normal bicycles when the electric power system is working. You will be able
to ride more easily. Please keep pedalling.
•When the electric power system stops working, the bicycle will not provide any pedal assistance.
•The e-bike can be used as an ordinary bicycle, even with no lithium battery.
•The speed limit is 25 km/h with pedalling power which means that, to ensure safety, the pedalling power will remain at 25
km/h even if you pedal faster.
•The range of this bicycle depends on specific circumstances. The value indicated is determined based on average conditions.
•The main factors are as follows: rider’s weight, riding speed, slopes, tire pressure, head-on wind, times of speed regulation
and braking (in the urban area) and outdoor temperature.
•When the temperature is rather low, a greater negative effect will be produced on its range.
