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.

To adjust the tilt of the handlebar, loosen the stem screw-pivot shown
in the picture below 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.

16
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.

It is already fixed above your rear wheel. The fasteners must be tightened and checked regularly at a torque of 4 - 6
Nm. Your luggage rack is designed for a maximum load of 25 kg, it is possible to attach a child seat.
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.
WARNING
Your luggage rack is not designed to pull a trailer.
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.
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). 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.
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.
