Safety Instructions

Please make sure that you’ve carefully read and understood the user

manual, before using your Coboc e-bike for the rst time, as it contains a

lot of safety relevant information.

Non-observance may lead to serious accidents, as well as personal and/or

material damage. If you borrow your Coboc e-bike to someone you should

insist that those borrowing it have completely read and understood the

manual before riding for the rst time.

The user manual is best kept close to your Coboc e-bike, so that it is

accessible at any time needed. Always drive responsibly, as cyclists are

exposed to increased risks, especially when riding on public roads. We

recommend wearing a safety helmet during every cycling trip. The safety

helmet should be correctly adjusted to your head and its intended purpo-

se. Follow the helmet manufacturers instructions. Wear a suitable outt. It

should be bright and you should attach reectors so that other road users

can recognize you early enough. Clothing in the leg area should have a

tight t so that your clothes can’t get caught in your Coboc e-bike.

Use cycle clips if needed. Entangling clothes in your Coboc e-bike may

result in an accident. Take into account the increased performance. Due

to the electric motor in your Coboc e-bike the performance is consider-

ably higher than that of ordinary bikes. On the one hand this means that

higher top speeds can be reached and on the other hand that more torque

is transmitted to the rear wheel. This may lead to unusual sliding of the

wheels, especially on wet ground.

Get used to your Coboc e-bike. The special characteristics of your Coboc

e-bike require you to familiarise with them in safe and open areas. Only

use your Coboc e-bike in public as soon as you have it under control.

Symbolism: for a more simple readability certain points in this user manual

are highlighted. We used the following symbolism for that:

INFO: This symbol highlights valuable information and points

worth knowing.

CAUTION: This symbol warns you against improper use, that may

lead to environmental pollution, damage to your Coboc e-bike or

other material damage.

WARNING: This symbol indicates possible health hazard and

danger to life, that may occur if the e-bike is being operated

incorrectly or used improperly.

Aligning handlebar and stem

First loosen both screws (1). The tting hex socket key is included with delivery.

Align the handlebar in a way that stem and front wheel are in line with each

other. Now tighten screws (1) again. Afterwards loosen the four screws in the

stem (3). Turn the handlebar into desired driving position and tighten screws

afterwards. Make sure that you tighten all four screws (3) equally.

Adjusting brake levers

Loosen the clamp screws (4) and adjust the brake lever according to your

preferred grip position. It should be comfortable and safe at the same time.

Afterwards tighten the clamp screws (4) again.

Setting headset bearing

Check if the headset bearing has play. To do that, you must pull the front brake

while pushing your e-bike back and forth a couple of times. The handlebar

should be able to slightly move from left to right, while bearing clearance should

stay at a minimum. If there is bearing clearance, again loosen both screws (1)

and slowly tighten screw (2) until the bearing has no play anymore. Afterwards

tighten both screws (1) again.

Do not tighten screw (2) too much, as this may lead to a damaged

headset bearing. If the handlebar only turns with effort, then this could

mean that screw (2) has been tightened too much. If this is the case,

loosen screws (1) in order to slightly loosen screw (2). Afterwards tighten both

screws (1) again.

• Hex socket key

SET-UP

Coboc e-bikes are almost completely assembled at the point of delivery. However,

handlebar and pedals are loosened for transport, which is why, prior to your rst

ride, you must bear in mind the user manual while taking the following steps. Par-

ticularly take into consideration the safety instructions and the indicated tightening

torque for screw ttings (s. chapter Maintenance & Care such as Tightening torque).

Checking tire pressure

Check for tire pressure before the start of every journey. The correct pressure

is given on the side of the tire and can differ depending on the tire model. The

minimum or maximum prescribed tire pressure for your Coboc bike must not

be fallen below or exceeded. You can nd information about this on the side of

your tire's sidewall. Driving with too little air pressure can damage the rim and

the tire.

Screwing on pedals

Lightly grease the pedal threads before screwing them into the intended cranks (5).

Both pedals have different threads and need to be screwed in at the

intended side. The right pedal has a right-handed thread, while the left

pedal has a left-handed thread. Mixing them up may lead to damaged

crank arms or pedal threads. Make sure both pedals are tightened.

COBOC ELECTRIC DRIVE

Operating the Power Button

Briey pressing the power button (7) of the user interface,

positioned at the bottom side of the top tube, activates the

Coboc Electric Drive. Your LED display (6) is going to show

at least one lit LED, in order to indicate the battery level

of your Coboc e-bike. Putting more force into the pedals

means unfolding more motor power. As soon as you stop

pedaling, the motor support stops too.

Because of the electrical support you are going to

be much faster and dynamic on the road than you

are used to with ordinary bikes. We suggest you

take your time to get used to this new driving behavior.

Battery level – LEDs are lit up

Errors – LEDs are ashing

RIDING

Your Coboc e-bike drives like an ordinary bike – only it’s more dynamic. The more

force you use to tread the pedals, the more force is unfolded in the motor. As

soon as you stop treading the pedals, the motor stops supporting you.

(8) (7)

(6)

You are going to be much more dynamic with your Coboc e-bike than

you are used to. Slowly get used to your Coboc e-bike.

Should you ever have the feeling that the motor support is tuning in too

early or too late, meaning at very low or very high pressure on the

pedals, note that you can always re-calibrate the torque sensor. You can

nd all the necessary information at our helpcenter www.support.coboc.biz/

navigating to 'Service and Care' g 'how do I calibrate my Coboc e-bike?'.

In the event of irregularities in operation or other mistakes, resetting the

user interface might help. To do this you need to press and hold the

power button (7) for about 20 seconds. Your e-bike is going to signalize

a successful reset by briey ashing the LEDs in blue and subsequently scrolling

them from left to right in green light.

CHARGING

The charging socket (8) is placed right behind the power button (7) at the user

interface. Simply connect the magnetic charging plug to start charging your

Coboc e-bike.

A full charge of the battery from 1% to 100% usually takes two and a half hours

with the regular Coboc charger ST 4A. However, the battery is already charged

to 90% after two hours, which means that the charging time for the last 10%

takes a bit longer (half an hour).

The ideal outside temperature for battery charging is somewhere between

5ºC and 25ºC. At temperatures below 0ºC or above 40ºC electronics disables

charging, in order to protect the battery from getting damaged.

5 LEDs are lit up in blue gbattery level of 80 % to 100 %

Please observe the existing regulations and laws in your country before

using your Coboc e-bike on public roads. Below are shown the current

most important regulations for Germany only. For a complete listing of

regulations we refer you to the according legislative texts. Since pedelecs

are a rather young vehicle category, so are related laws and regulations. As

these regulations are constantly changing, please make sure to frequently

check for any changes in legislation and regulation.

Within the EU, pedelecs with assisted pedalling up to 25 km/h and a

motor with a continuous performance of 250 watts are controlled with the

same regulations as ordinary bikes. E-Bikes with pedal assistance that may

reach higher top speeds and/or higher motor performance are, according

to EU directive 2002/24/EG, referred to as low-performance mopeds. Such

vehicles require a type approval, such as the duty to wear a helmet and an

insurance obligation.

Coboc e-bikes are shipped with 25 km/h and a motor performance of 250

watts as standard, which is why, according to EU directive 2002/24/EG,

they are exempt from type approval.

German road trafc regulations (StVO) and road trafc licensing act

(StVZO) apply if using public roads. Additionally, the StVZO requires the

following for e-bikes:

A clearly audible bell.

A permanently xed lighting system with white headlight and red rear

light. In order to use the lighting system, e-bikes need to be equipped

with either a generator or a rechargeable energy storage or a combination

of both.

The following reectors need to be attached to the e-bike:

• A white reector in the front.

• A red reector in the back, it may not be a triangular reector of the

category “Z”. It may, however, be integrated into the rear light.

• Laterally tted reectors have to be attached at the front and rear part

of the e-bikes, while at least one has to be attached to the spokes.

Alternatively, you may use tires with reective rings on both front and

rear ends. Every laterally tted reector needs to have the same colour

(yellow or white).

• Pedals need to be equipped with reectors radiating to front and

back.

According to StVZO, bicycle bell and reectors need to be attached to the

e-bike for use on public roads. If necessary a lighting system needs to be

retrotted to the e-bike. Please make sure that your lighting system is at

no time concealed. You may not use your Coboc e-bike on public roads if

the lighting system is somehow damaged. Please contact your local Coboc

dealer if repair or maintenance is necessary.

Responsibility for road safety for every Coboc e-bike remains with the

customers.

Intended Use

Weight information for your Brooklyn FAT

Don't overload your Coboc e-bike. The permissible total weight must

not be exceeded. It consists of the weight of the Coboc e-bike + rider +

luggage.

max. total weight bike weight max. rider weight

140 kg 13.4 kg 120 kg

Don't take anyone with you. Your Coboc e-bike is designed solely

for the transportation of individuals. Exceptions are the transport

of children in a suitable child trailer or child seat. Observe the

national legislation and the permissible total weight of your Coboc e-bike.

According to the StVO, the transportation of luggage requires a suitable

device on the bicycle.

Your Coboc e-bike is not meant to be exposed to extreme stress

like riding stairs or ramps, so we recommend avoiding such

scenarios.

Your Brooklyn FAT is designed for use on paved roads and paths. The

wheels must remain in constant contact with the ground. Always ensure

sufcient air pressure in the tires, otherwise your rim could be damaged.

If your Coboc e-bike is equipped according to the national legislation, it

may be used on public and paved roads. Please bear in mind the tips in

chapter 5 – Legal regulations.

Also note that complying to the operation and maintenance conditions ex-

plained in this user manual is part of the intended use for Coboc e-bikes.

Your Coboc e-bike is not a toy. Do not let children handle your

Coboc e-bike without detailed instructions or leave them

unattended at any time. You should brief children on the dangers

associated with the use of electronic devices. Please follow the regulations

for minimum age of use that are valid in your country.

Your Coboc E-Bike is not designed to tow (child) bike trailers, nor

to attach a child seat.

The A-weighted emission sound pressure level at the rider's ears

is less than 70 dB(A).

Coboc itself, as well as dealers do not assume any liability for use

beyond the intended use. This applies in particular to non-com-

pliance with the instructions in this user manual.

12 Before every Ride

The A-weighted emission sound pressure level at the driver’s ears

is less than 70 dB(A).

Coboc, such as our dealers, assumes no liability for any use other than the

one intended, especially regarding non-compliance with the information

given in this user manual.

Before every ride

Make sure your Coboc e-bike is ready for operation and that it is adjusted

to your body height. Saddle height and handlebar position should be

adjusted properly. Your saddle should be set to a comfortable and safe

height.

Choosing a frame size that does not suit your height or a

defective adjustment may lead to loss of control and ultimately

may lead to slips or crashes which again may lead to serious

injuries and damage. If you have problems with picking the right frame size

or how to properly adjust your Coboc e-bike, please refer to your local

Coboc dealer.

Adjusting the saddle height

The seat post may under no circumstances be put higher than the

minimum depth of insertion. A mark at the seat post signals the

designated minimum depth of insertion. Pulling the seat post out

too far may result in crashes and serious damage to you and your e-bike.

By using your Coboc e-bike when the minimum insertion depth is

undershot, the Coboc manufacturer's warranty for any resulting damage to

your e-bike is void.

You may position your saddle in three different directions. First, make sure

that the seat post clamping at the frame and the saddle clamping at the

seat post are rmly tightened. Sit on the saddle and put one foot on the

pedal while posting your other foot on the ground. Now use your heel to

carefully tread the pedal until the crank arm is in line with the saddle tube.

If you are standing on the pedal but your leg is not fully extended, this

means that the saddle is probably too low. Vice versa if you have to reach

for the pedal or if you have to tip your pelvis forward, that means that your

saddle is positioned too high. If needed, you can loosen the seat post

clamping at the frame, adjust the correct saddle height and tighten the

clamping again.

Make sure that the saddle is in line with the top tube of your e-bike. Again,

you may loosen the seat post clamping, in order to move the saddle left

and right, before tightening it again. It is also possible to change the sadd-

le tilt relative to the top tube. Just loosen the clamping at the seat post,

adjust to your needs and tighten again.

Align the grips

Ergonomic Ergon GA30 grips are installed on your Iseo. With their

enlarged contact surface on the ball of the hand, they effectively prevent

the wrists from kinking and enable fatigue-free riding. So that they can

perform their function optimally, they must be mounted so that the contact

surface is horizontal.

Please bear in mind the permissible torque for all these steps (s.

table Tightening torque) and make sure that all screw ttings are

tightened before using your Coboc e-bike or sitting on your sadd-

le to adjust it again.

Regular monitoring

Make sure that the lighting system on your Coboc e-bike works in the front

and in the back.

You should be able to reach both braking levers without any problems.

Also make sure to know which braking lever applies to which brake. As

13

standard, the right brake lever applies to the rear brake and the left brake

lever applies to the front brake. Note that the braking distance increases

and that the tires might block faster if the ground is wet.

Make sure that the screws for your saddle, handlebar and brakes are

tightened enough (s. table Tightening torque). In case of doubt you can

try twisting saddle, handlebar or brakes. Nothing should move. Also make

sure to regularly check all other screw ttings and ensure yourself that they

are tightened correctly. Make sure that frame and fork are not damaged.

Check regularly for abrasion of friction components within the brakes (s.

chapter Maintenance & care).

Testing the brake system

Push your Coboc e-bike forward while pulling the rear brake. If everything

is adjusted correctly the rear wheel should be blocking. If applying the

front brake, your rear wheel should leave the ground. Steering should not

rattle or have any play. The brake levers should not be pulled more than

halfway through during this test.

Before every Ride

Checking the wheels

Check the wheels and tire pressure! Inspect the tires and rims for abrasion,

damage, tears, deformations or smaller pieces that might be pushed in

(e.g. glass fragments or nails). We advise you to use a suitable bicycle

pump with built in pressure gauge. The optimal tire pressure is indicated

on the side of the tire and may differ depending on the tire model. In case

of doubt, or if you use components other than those already built in as

standard, please refer to the tire manufacturer, to ask for the correct tire

pressure. If tire pressure is too low, there is an increased risk of having at

tires due to rims pressing through the tire. Furthermore this might cause

sustainable damage to the rim.

If the pressure is too high, tires or rims might be damaged. In any case, wrong

tire pressure might cause crashes.

If you are not sure whether your Coboc e-bike is in technically

safe condition, do not start your ride. Let your local Coboc dealer

or a service partner check your e-bikes condition.

If you use your Coboc e-bike extensively then make sure to have your

e-bike checked more regularly from your Coboc dealer or a service partner

(s. chapter Maintenance & care).

Before your ride, make sure that your battery level is high enough

for the intended journey (s. chapter Battery level).

14

We assume that as a Coboc e-bike user you have gathered enough basic

experience with ordinary bikes. If this is not the case, we recommend

practicing on a e-bike without motor support. Because of the strong acce-

leration and the increased maximum speed it is recommended for you to

be able to handle e-bikes very good.

Get used to your Coboc e-bike. The special driving characteristics for

Coboc e-bikes require for you to familiarize with it on different terrain.

Make sure that you got it under control before starting to use your Coboc

e-bike in public.

Operating the Coboc Electric Drive

Your Coboc e-bike has two operating modes:

“Bike off” / manual riding: You can always choose to ride your e-bike with-

out motor support. Motor support is turned off, if the ve LEDs on the top

tube are not lit up. You should keep motor support turned off, if storing or

not using your Coboc e-bike.

“Bike on” / riding with motor support: Pressing the power button turns on

motor support for your Coboc e-bike. Motor support is turned on, if the

ve LEDs on the top tube are lit up. In a turned on state LEDs indicate the

battery level and motor support goes up to maximum speeds of 25 km/h.

Turning off

To turn your e-bike back off, just press the power button again in “bike

on” mode. Your Coboc e-bike turns off automatically after staying unused

for more than three minutes.

Notes on using the brakes

Make sure to know which brake lever belongs to which brake before star-

ting your ride. As standard the right brake lever belongs to the rear wheel

brake and the left brake lever belongs to the front wheel brake.

Regularly check the friction components for wear.

Handling

It is important for you to also check the wear on your rim brake anks.

Also make sure to check for brake pad wear on the brake shoes (s. chapter

Maintenance & care).

If wear is too heavy on any of these components, this may lead to total

failure of the brake system. Hard falls and serious injury can be the result.

Use your brakes in a controlled and well-timed way. Too heavy

breaking may leave your wheels blocked and therefore lead to

loss of control. Hard falls and serious injury can be the result.

Hydraulic disc brakes

Avoid using the brakes permanently if riding downhill for longer periods

as this might cause steam bubble formation and therefore lead to loss of

control. Hard falls and serious injury can be the result. Always try to fully

release the brakes or to switch between front and rear wheel brakes. That

way the brake system can cool off. If necessary take a short break to cool

it off. Always check the braking point before your journey. If you are able

to pull the lever all the way back to the handlebar or of the braking point

changes while riding you may not continue riding. Let your Coboc dealer

either bleed your brake or x it, if needed.

Level of motor support

The level of motor support adapts to your driving behavior. The stronger

you tread the pedals, the more torque value is in the motor. This makes a

“level of support” choice unnecessary. However, you can apply a ne-tun-

ing of your Coboc Electric Drive on your phone via our Coboc App. Please

note, that you may not use the Coboc App while riding your e-bike (s.

chapter Coboc App).

Two different driving modes

Since rmware version 3.34 you are able to choose between two different

driving modes. You can either acces them via our Coboc App or by simply

operating the power button on your e-bike.

15

Drive settings for both modes can be adjusted individually and remain

even if smartphone and e-bike are not connected.

A double press of the power button allows you to switch between the two

driving modes. The second mode switches colors for the LEDs from blue

to sea green.

Only start pedaling if seated securely on your Coboc e-bike. As

soon as pressure is applied to the pedals, the motor support is

set free. If you want to sit on your e-bike by putting on foot on

the pedal while swinging over the saddle with the other leg, be aware that

the e-bike might abruptly start moving. Risk of falling!

Stop pedaling in time. Motor support is stopped as soon as the crank

stops turning. Be aware of this especially before road crossings and curves.

If you have any problems with your drive (ie. because you did not stop

pedaling in time) you may always stop the motor by using the rear wheel

brake.

Handling Battery & Charger

Reach

Your Coboc e-bike is equipped with a modern lithium-ion battery. This

type of battery offers the best state-of-the-art energy density, which means

maximum reach at minimum weight. Furthermore, lithium-ion batteries

have no memory effect. This battery has a nominal voltage of 36 volts and

a nominal capacity of 380 Wh.

The battery on your Coboc e-bike is installed into the e-bikes

frame. This way of installation allows for a very low vehicle weight

while providing ideal protection against moisture. The battery

remains in the frame even for charging. Only trained personnel is allowed

to remove the battery.

Do not remove the battery by yourself! Under no circumstances

should the cover at the bottom of the down tube be opened.

Only trained personnel should carry out maintenance or repairs

on the installed drive system. Carrying out maintenance or repairs may

result in danger to life due to live parts such as cables and contacts.

Furthermore, the drive system is being protected against moisture by a

special sealing technology, which is why warranty obligations become inva-

lid if the down tube is being opened without the approval by Coboc.

Reach: The range of your Coboc e-bike is heavily dependent on various

inuencing factors and can therefore uctuate. These include the following

factors, among others: the type of surface, incline/slope of the route, wind

conditions, tire characteristics, air pressure, driver weight, cadence, driving

speed and temperature. The settings of the drive parameters also have an

impact on the range of your Coboc e-bike. Information about the Coboc

app and the setting of the individual drive parameters can be found here:

www.coboc.biz/en/the-coboc-app/.

With a fully charged battery and on level terrain, preset mode 1 (blue

LEDSs) can be used to achieve approx. 75-110 km. When driving on as-

phalt roads, a low tire pressure can increase the rolling resistance and thus

reduce the range. Headwinds or hilly terrain will also have a negative im-

pact on the range. Increasing the drive parameters via the Coboc app will

express itself in stronger support but in return in a shorter range. A higher

total weight will also reduce the range of your Coboc e-bike. If you drive

English

16

over 25km/h in return, the motor support is switched off and you ride your

e-bike like a normal e-bike. This increases the remaining range accordingly.

On hot days (battery temperature of more than 60° C) the battery turns its-

elf off for safety reasons. After that, it has to cool down before you are able

to use it again. If your e-bike has not been turned on or charged for more

than 30 days, it automatically sets itself into a deep sleep mode in order to

save battery power. If in deep sleep mode, your Coboc e-bike can not be

turned on. However, you can reactivate it rst by plugging in the charger.

Battery level is displayed on the user interface. Up to ve LEDs light up

after turning on the Coboc e-bike. They are split up as follows:

If more than one LED is ashing red this indicates an error within

the drive system. See chapter “Error codes” for more insight.

Charging the battery

The ideal ambient temperature for battery charging is somewhere bet-

ween 5ºC and 25ºC. At temperatures between 0ºC and 40ºC electronics

disable charging, in order to protect the battery from getting damaged.

Please refrain from using any charger other than the one included

in your delivery from Coboc or chargers authorized by Coboc.

Modern lithium-ion batteries require chargers that are perfectly

matched, as everything else could lead to the battery catching re or even

exploding.

Make sure to check the charger for any external damage (case,

plug or cables). Under no circumstances should you use a

damaged or faulty charger.

5 LEDs are lit up in blue gbattery level of 80 % to 100 %

4 LEDs are lit up in blue gbattery level of 60 % to 80 %

3 LEDs are lit up in blue gbattery level of 40 % to 60 %

2 LEDs are lit up in blue gbattery level of 20 % to 40 %

1 LEDs are lit up in blue gbattery level of 1 % to 20 %

The charging socket is situated at the bottom side of the top tube. You can

only insert the plug in one direction. Socket and plug are magnetic and

stay attached if connected correctly.

Before plugging in the charging plug, check whether metallic

objects have adhered to the plug's magnets. This could lead to a

short circuit when plugging in the charging plug.

Only charge the battery at dry and well ventilated places, as the charger

should not be exposed to rain, water or moisture. Make sure that there are

no ammable or hazardous substances in the room when charging your

e-bike. Always keep your charger in a safe place, in order for it not to fall

down or tip over.

You should only use your charger in indoor areas. Also, notice

further hints directly on the charger and the provided user manual

for the charger.

In order to charge your battery you need to plug the mains into a tting

outlet and connect the charger with your Coboc e-bike. Make sure that

the mains and the needed voltage meet your countries standards. The

provided charger is designed for a line voltage of 220V and 240V.

Charging begins as soon as the charger is connected and turns your Co-

boc e-bike off it was turned on beforehand. You can not turn your Coboc

e-bike on while charging it.

LEDs are now lighting up one after the other in order to indicate the

charging process. If your Coboc e-bike is fully charged it turns itself off

automatically. As soon as that is the case the charger indicates that the

e-bike is fully charged.

A complete charge from 1% to 100% takes two and a half hours with the

Coboc charger ST 4A. However, the battery is already charged to 90%

after two hours, which means that the charging time for the last 10% takes

a bit longer (half an hour).

You can keep your Coboc e-bike connected to the charger even after

charging is completed. The battery does not overcharge. However, we

Battery & Charger

recommend you to unplug the charger from your Coboc e-bike and the

mains out of safety reasons.

Make sure that your homeowner’s and re insurances cover lithium-ion

battery charge and pedelecs in general. Also regularly check newspapers

for any changes in the legal situation.

Storage

If your e-bike is not going to be used for a long time, it should be

fully charged beforehand. If the e-bike has been fully charged, it

must be connected to a charger after eight months at the latest.

The e-bike should never be stored with an incompletely charged battery. If

the battery is deeply discharged because it has not been charged for too

long or the e-bike has been stored with insufcient battery, the damage is

not covered by the warranty or the manufacturer's guarantee.

A permanently high state of charge causes the battery to age faster, while

deep discharge can permanently damage or even destroy the battery. We

therefore recommend charging the e-bike completely before storing it,

removing the charger and storing it in cool temperatures of around 15 ° C.

Lithium-ion batteries discharge themselves over time. Therefore, the

battery level falls within the optimal range for storage within the rst few

days, until the E-Bike automatically switches to energy-saving mode after

30 days. If the battery is fully charged, it must be fully charged again after

8 months at the latest. If it is not fully charged, earlier accordingly.

Your e-bike should not be stored permanently at temperatures warmer

than 20 ° C. To prevent deep discharge, your Coboc e-bike automatically

switches to an energy-saving mode after it has not been used for a long

time. The e-bike cannot be switched on in this state. It can only be reacti-

vated by connecting the charger.

Never store the battery with the charger plugged in all the time. If

the battery is permanently charged to 100%, aging will accelerate

and the battery will quickly lose capacity.

Transport

Lithium-ion batteries with stored energy higher than 100Wh are subject to

international legislation on dangerous goods. The battery installed in your

Coboc e-bike has a stored energy of 380 Wh and is therefore classied as

a class 9 dangerous good. Therefore, transport by road, sea or air must

be specically authorized beforehand. It is mandatory to seek advice of an

expert on dangerous goods.

Please bear in mind, that many transport companies have certain guide-

lines for the transport of devices or vehicles equipped with lithium-ion

batteries.

Disposal

Do not dispose of your Coboc e-bike, battery or charger in the household

waste.

Within the EU there is an obligation for the consumer to return no

longer usable batteries and a redemption obligation for dealers,

manufacturers and importers. In accordance with EC directive

2002/66/EC, faulty or used batteries have to be collected separately and

disposed of in an environmentally-friendly manner.

Please take used batteries with you to a collection point for recycling, your

Coboc dealer or directly to us. Removing the battery from your Coboc

e-bike should only be done by trained personnel.

Maintenance and repairs on the drive system may only be carried

out by trained personnel. Under no circumstances should you

open the cover at the bottom of the down tube. Carrying out

maintenance or repairs may result in danger to life due to live parts such as

cables and contacts opened. Furthermore, the drive system is being

protected against moisture by a special sealing technology, which is why

warranty obligations become invalid if the down tube is being opened

without the approval by Coboc.

18 Maintainance & Care

Turn off your Coboc e-bike (“Bike off”, possibly turn off the lights,

too). Always make sure, that your Coboc e-bike is turned off

before performing any maintenance or repair work. The motor

could start abruptly, if repairs are done on a turned on Coboc e-bike or

contacts at the motor plug could be under power. Both could lead to

serious injury.

Do not remove the bottom bracket! The bottom bracket on your Coboc

e-bike is equipped with a sensor that is internally wired with the drive

system. Improper disassembly can cause damage to cables or sensor.

Care instructions

Regularly clean your Coboc e-bike from dirt. Not only does it preserve

good looks but also can it help keep functions alive. Never use hard water

jets like high-pressure cleaners or garden hose to clean your e-bike. Only

wash it by hands and never put it upside down. Electronics and ball bea-

rings are sealed tightly, which allows for regular operation even on rainy

days. However, high-pressure cleaning might cause uids or dirt to enter

through the seals and could damage bearings or electronics.

Always keep your chain greased. This allows for a low-noise operation and

minimizes wear. Make sure to use appropriate chain oil.

Safety Instructions for Carbon Components

We added a high-quality and very light carbon fork to reduce weight and

to rene looks of your Brooklyn FAT.

Components made out of composite material might be damaged at

places not visible at rst sight. Damaged parts may lead to immediate

failure and cause falls. Therefore, having the according parts checked for

functionality or non-apparent damage by the manufacturer is mandatory

after crashes or hard falls. Replacing and destroying the damaged parts is

also an option.

Furthermore, carbon parts need regular visual inspections. Check if single

layers like paint, nish or ber are detaching. Look for changes on the sur-

face of the according parts, like chipping, holes or deep scratches. Make

sure to check if the components are getting softer or less stiff and solid.

If this is the case with one or more components, they should be replaced

immediately.

Special Features of Carbon

Carbon bre reinforced plastic is a lightweight material that has very speci-

c properties. Understanding these properties is mandatory in order for a

hazard-free use and a long operation without defect.

Carbon can be used to build extremely lightweight high-strength and

robust bicycle components, if processed correctly.

However, a disadvantage of this material is, that possible damages might

not be visible from the outside right away, as carbon does not deform

at overload like aluminum or steel might do. The material might keep its

shape even though the inner structure is already damaged. A damaged

structure inuences stability of the component and therefore might lead to

serious falls and injuries. If you have concerns regarding the condition of

one of the carbon components, make sure to visit your Coboc dealer.

If you hear pops, this might indicate defect on a carbon

component. Check the screw ttings on your carbon components

for correct torque regularly. Should there still be audible pops,

make sure to contact your Coboc dealer. Under no circumstances should

you continue using the damaged component.

Carbon components should never be heated up to high

temperatures, as would be the case for powder coating or

stove-enamel nishes. The appearing heat might damage compo-

nents. Also avoid storing your e-bike in a vehicle that is exposed to strong

sunlight.

Care Instructions for Carbon Components

Clean your carbon components with a soft cloth and clear water. If that

should not be enough you might add some detergent or use a petrole-

um-based cleaner.

Maintainance & Care

Never use degreasers containing acetone, methyl chloride or

trichloroethylene. Chemical or not neutral cleaners that contain

solvents could attack the surface and therefore weaken the

component.

Lightweight carbon parts may be exposed to increased wear.

Please follow the instructions on service intervals and have your

carbon components checked for defect or wear regularly by your

Coboc dealer.

Carbon components should never be greased. Doing so leads to

grease entering the surface, which makes tight clamping within

the permitted torque value impossible. We recommend using

carbon paste instead, as increased friction makes less torque value

necessary to clamp safely.

Check your carbon components for optical damage such as

notches, dents, tears, discoloration, etc. Should you notice any of

these defects, make sure to contact your Coboc dealer and

refrain from using your e-bike until doing so.

Inspection

Modern technology is very high in performance, but still needs a certain

amount of care. Because of that, please make sure to maintain your Coboc

e-bike on a regular basis. To guarantee a reliable functioning and in order

to ensure your warranty claims make sure that:

Your Coboc dealer or service partner checks your e-bike at least once a

year, if not more regularly.

The rst inspection of your Coboc e-bike is of particular importance for an

easy and reliable functioning. Cables and spokes may stretch, while screws

may loosen themselves. Therefore, please make sure to have your e-bike

checked by your Coboc dealer or service partner after the rst month of

operation or the rst 100 driven kilometers.

The following table shows time spans that may serve as indications for

cyclists that ride between 1500 and 2500 km a year. Riding on poor roads,

in bad weather conditions or simply riding more than 2500 kilometers in

a year, makes the service intervals shorten accordingly. If you do not have

the technical know-how to maintain your e-bike, please make sure to have

it checked by your Coboc dealer or service partner.

• Make sure that your brakes are working properly before every ride.

Both brakes should work awlessly and delay sufciently. You should

not be able to pull the brake levers all the way to the handlebar.

Check the wear of the brake pads and the brake disc approximately

every month (s. Adjusting the brakes).

• Check the condition of your brake lines regularly. Under no circum-

stances should brake lines be broken or brake uid leak out.

• Make sure to check pressure on both tires before every journey.

Recommended tire pressure is dependent of the type of tire you are

using and is usually indicated on the sidewall of the tire. If you want

to utilize other tires, please make sure that rims and tires are compa-

tible and that the maximum permitted air pressure for rims and tires

are not exceeded.

• Make sure that the valve is looking straight out of the rim. It should

be more or less aligned with the spokes. It could rip off, if not positi-

oned correctly.

• Check for lateral bearing clearance on the wheel hubs roughly

once a year. Please replace the wheel bearing if the rim is moving

although the tire is screwed tightly to the frame. The same applies,

if wheels are not running smoothly without brakes sliding. Please

contact your Coboc dealer in this case.

• Check for bearing clearance on the pedals once a month by trying to

move them across the pedal axles. You should replace the bearings,

if you can move the pedals from side to side. Please contact your

Coboc dealer in this case.

• Roughly once a month should the crank lever screwing on the spind-

le be checked. Use a torque wrench to screw the crank lever with the

according tightening torque (s. table Tightening torque).

• Check the spoke tension on your tires roughly once a month. To do

this, simply press two adjacent spokes together with one hand. This

helps you nd out if one of your spokes is more loose than others.

Should this be the case, make sure to visit your Coboc dealer in

order to center the according wheel.
