THE CITYSURFER
The Citysurfer is what we colloquially call a pedelec. An electrically assisted
pedal bicycle, following the Standard UNE-EN 15194: 2009 and the
European Normaives that regulates these kind of vehicles, designed for a
sustainable mobility.
It has two brakes, the front one (called v-brake) and the rear one (a disc
brake), shich can be operated sith the handlebat levers, as in any bike or
motorbike. A little digital control apnel in the handlebar allows us to switch
the ebike on and off and to select one of the three different power assistance
modes. The electric motor will only work while pedalling, assisting you more or
less due to a sensor and the operating modeddsfa. The feeling of assistance
in slopes and plains is very pleasant, stopping from working when braking or
not pedalling, getting a natural ‘feeling’. Take into account that the pressure
of the tyres, weight of the cyclist of the load carried will affect the power and
the battery range. We will explain below how to improve the performance of
your Citysurfer ;-)
As far as size is concerned, the Citysurfer is suitable for any gender and age
and easily regulable in handlebar and seat’s height, to adapt it to different
heights, offering a made to measure comfort to each person.
Furthermore, the Citysurfer is easily foldable, so it can be stored anywhere.

BEFORE USING IT
Verify that the box where the Citysurfer is delivered contains the following
elements:
Citysurfer bicycle folded.
Pedals installed in the bicycle.
Bicycle saddle with quick release system (both of them loose).
Charger with its power cord.
Lock keys for the battery (2 units).
A battery placed inside the frame.
Due to the fact that we assemble the bike in our Mataro’s factory, we test
the proper operation one by one. However, we want to ask you to check
again some components and t them to your necessities an tastes.
TYRES PRESSURE
A pressure between 3,8 y 4,5 BAR (kgf/cm2) is recommended. The correct
pressure will increase the range. The pressure of an electric bicycle is
always higher than in a normal bicycle.
BRAKES
Check that the front and rear brakes work, actuating on the left and right
levers of the handlebar while moving slightly your e-bike. If the brake lever
has too much travel, you can adjust the tension of the brake cable by
applying torque and counter-torque to the nuts situated in the levers.
ADJUST THE HEIGHT OF THE SADDLE AND HANDLEBAR
Adjust the Citysurfer to your height to achieve a comfortable handling and
riding by regulating the height of the saddle and the handlebar with the
quick release systems marked in the images.
Recommendation: The height of the saddle should be lined up with your
hip.
HOW TO ADJUST THE FORK
You can adjust the preload of the fork to adapt it to your weight and
preferences. To increase the preload, turn clockwise the wheel situated in
the right bar of the fork. To reduce it, the wheel must be turned anticlockwise.

HOW TO FOLD IT
Folding the Citysurfer is very easy. The
system to fold the bike is located on the
central part of the frame, on the right side
of it. Firstly, turn upwards the security black
piece to unlock the folding lever. After that,
pull outwards the silver lever. In this moment
the frame is free to be folded in half*.
Push the secure close button located in
the base of the steering shaft to fold the
handlebar. Then pull downwards the lever
and the handlebar will be released. Move
the handlebar in the direction of the hinge
to place it beside the wheel. The cables are
designed to change their position without
any problem.
You can also lower the saddle to its end
and fold the pedals to take less space. The
pedals can be folded by pushing the trigger
placed in the centre of the pedal and then
turning it down.
*Attention! The rst times we fold and unfold the Citysurfer we might notice a slight
resistance. In a short period of time it will ‘go as smooth as silk’ ;-).

GEAR SHIFTER
The Citysurfer has a 6 or 7 speed shifter depending on the model (Citysurfer
Standard or Citysurfer GT) both controlled by a Shimano Revoshift grip
located on the right side of the handlebar.
To change gears on your e-bike, keep a constant pedal cadence and try
the different speeds by turning the grip shift until you nd the one you feel
more comfortable. The grip shift has a little window that show you the
speeds, numbered from 1 to 6 (7 in the Citysurfer GT) . The rst speed (1)
corresponds to the shortest gear and is recommended for slopes and the
last one (6) (or 7 in the Citysurfer GT) is the longest gear, which is more
adapted for higher speeds.
- To put the bike into a lower gear to achieve an easier pedalling, turn
the grip shift towards the minus sign (-). This will gear down your electric
bicycle but will also make you pedalling faster to achieve the same speed.
- To get a higher speed (in a plain road or in a downhill) turn the grip shift
towards the plus sign (+) to choose a higher gear. This action will increase
the pedalling resistance of your Citysurfer, allowing you to pedal more
slowly to reach to a certain speed.
Always pedal forward while keeping a constant pedal cadence when
changing gears. The gears work independently of the motor. To maximize
the battery range and to have a pleasant aerobic exercise, use the gears
to help the motor.

CONTROL PANEL
a. Turning on/off the electric system
You can connect the electric pedal assist system by pressing the On/Off
button in the Control Panel placed on the handlebar. All the leds will switch
on and off checking the proper operation of the electrical system when the
button is pushed. If there isn’t any light ashing at the end, everything is
correct.
From that moment on, the control unit activates all the elements of the
system and the motor will assist you when you start to pedal. The operation
of the pedal-assist depends on the pedalling rate (cadence). The faster you
pedal, the more assistance you will have, according to the legal limit of 25
km/h. From that point on the motor will be disconnected.
b. Pedal-assist levels
The system has 3 power levels of pedal assistance. To set a low or a
high assistance, you will have to push the MODE button as many times as
necessary until you reach the power level of assistance that you desire.
In the LOW assistance level, the energy supplied by the battery is the
minimum, allowing a higher range with less assistance. In the HIGH
assistance level, the pedal assistance is maximum and consequently the
range will be slightly reduced.
Recommendation: Start to pedal in a short gearing (big sprockets) and in
the low assistance level. As a result of this you will have higher control and
safety, less energy consumption and therefore more range.
For safety reasons, the pedal assistance is disconnected when the brakes
are operated.
The Citysurfer can be used as a conventional bicycle if it is necessary, that
is, without pedal assistance. The bike is equipped with a brushless DC
electric motor with little friction. Therefore, the pedalling without the motor
assistance does not imply additional resistance.
c. Charge level indicator leds. Battery Range
The control panel has a charge level indicator that shows the remaining
battery storage capacity. This indicator has 4 leds that turn off while the
battery is running down. The battery is at 100% when the four leds are
turned on.

MAINTENANCE
SERVICE
It is recommended that you go to your authorised dealer to check your bike
regularly. It is convenient to do a rst service in the three rst months, a
second after one year and so on. Regular inspections can avoid long-term
damages and also unnecessary expenses.
You can also contribute to keep your bicycle in excellent conditions as long
as possible. In the following sections we will show you how.
GENERAL MAINTENANCE
- Check the pressure of the tires and their condition.
- Verify the brakes wear and make an adjustment frequently.
- Avoid dirt accumulation between the magnetic disc of the pedalling sensor
and the sensor which are situated in the right side of the bottom bracket.
- You can clean your bike removing the dirty with a brush and hot water.
Never use a high-pressure cleaner.
- After cleaning it, dry the bicycle with a smooth cloth.
LUBRICATION
Apart from a regular cleaning, it is also convenient to lubricate the
transmission chain to avoid risk of corrosion and to increase the comfort
while changing speeds.
We recommend you to lubricate the chain with Teon grease that you can
nd in your frequent bike store.
REGULATION OF THE FOLDING SYSTEM OF THE HANDLEBAR
It is normal that the quick release system of the handlebar becomes loosed
because of the use. To reduce this clearance, the quick release system has
two grub screws which can be tighten with a 2.5 allen key. Screw both half
of turn and try if the handlebar is securely hold in its position. If not, repeat
the process again until achieve it.

TYRE CHANGING
In case you need to replace the rear tyre or change the inner tube because
of a puncture, follow these steps:
- First put the shifter in the longest gearing (small sprocket).
- Then disconnect the wire that comes from the motor shaft. The connector
is placed below the chainstay . The male and female connectors have
an arrow drawn on them that must meet when plugged again.
- Remove the black caps which protect the end of the wheel axle.
- Afterwards unscrew both sides of the wheel axle with an 18mm
spanner.
- Now you can remove the wheel and replace the rear tyre with a new
one .
To assembly it again, repeat the reverse process.
Pay attention when assembling the washers of the wheel axle. In each side
of the wheel there is a washer with a groove that must meet with the slots
of the dropouts.
Remember to put the motor’s axle with the wire pointing downwards to
avoid the water from entering to the hole of the axle.
The wires that leave the motor’s axle are protected with a metallic hose.
Check that this hose is slightly introduced in the motor’s axle to avoid cuts
in the wires.
