Dear Customers,
Thank you for purchasing a B'TWIN electrically-assisted bike. It will introduce you
to the joys of travelling on 2 wheels for your leisure, it will be the most practical
and economical way for you to get around in town and will allow you to burn
calories to keep t.
We invite you to read this instruction manual to get the best out of your B'TWIN
electrically-assisted bike.
Never forget that an electrically-assisted bike is not a moped. It needs your help
to go further and faster for longer.
We suggest that you learn how to use your electrically-assisted bike in an open
area in order to get used to the feel of the motor kicking in and thus ensure
optimum control of your bicycle.
Only use sport mode for your rst kilometres if you are sure that you are able to
control your bike.
Here are the 10 commandments to get the best use of your B'TWIN electrically-
assisted bicycle.
1. "pedal or you won't go far"
The bike's range is closely linked to the energy produced by the cyclist. The motor
on the electrically-assisted bike is only there to supplement the force produced
by the cyclist.
2. "inatethetyresoryouwon'tgofar"
The bike's range is linked to the tyre pressure, like a car. If the tyre pressure is
insufcient, you will consume more than necessary and reduce your range.
3. "inatethetyresoryouwillgetapuncture"
Resistance to punctures is closely linked to the pressure in the tyres. An
electrically-assisted bike is heavier than a standard bike and is therefore even
more susceptible to punctures if the tyres are under-inated.
4. "thecolderitis,theshorterthedistanceyoucantravel"
The range of your battery is linked to the outside temperature. The range
displayed for an electrically-assisted bike is calculated based on an operating
temperature of between 20°C and 25°C. If the temperature is lower, the range
will be reduced.
5. "themoreweightthebikeiscarrying,theshorterthe
distanceyoucantravel"
The battery range is linked to the weight of the cyclist and/or the load on the
bicycle. Just as for a car, the more weight the vehicle is carrying, the more it
consumes. Your range will be reduced if your bike is extremely overloaded. The
ranges displayed are given for an overall load of 80 kg.

3
6. "youdon'tget100%oftherangeattherstpushonthe
pedals"
The range is only at its maximum after 5 full battery charges. All the batteries used
on our electrically-assisted bikes are memory-free (an average of 300 cycles at
100% charge) and recyclable, but they only acquire their full range after several
full charges. The rst charge should give you approximately 70% of the range
indicated.
7. "thesteepertheslope,theshorterthedistanceyoucan
travel"
The battery range is linked to the gradient of the terrain. Electrically-assisted
bikes consume the most when going up-hill. This can even lead to breakdown
linked to motor overvoltage. If your trip includes a very steep gradient, choose a
bike with gears allowing you to go up it easily.
8. "youshallcheckthebatterychargeevenwhenyoudon't
use it"
The battery has a discharge limit threshold. If you leave your electrically-assisted
bike for more than three months without charging it (with an initial charge of
100%), the battery will be destroyed. If you have an electrically-assisted bike in
a holiday home, bring your battery home with you to check it and recharge it if
necessary.
9. "onthelastLED,youshallrideinecomode"
Electrically-assisted bikes have a battery gauge. The motor power on the last
LED will be weaker than on the rst LED's.
The electrical power remaining in the battery can only be checked with the vehicle
at a complete standstill, as while you are moving, the counter shows uctuating
LED's corresponding to the force the motor is drawing from the battery. When
you are on the last LED, the battery is down to its last dregs, the equivalent to
the reserve for a car. Switch to eco mode to avoid having to pedal home without
assistance.
10."ifanytechnicaloperationsarerequiredonthebicycle,
youshallswitchofftheignitionandyoushallremovethe
battery"
Repairs on electrically-assisted bikes are more technical and require a minimum
number of precautions to be taken.
All operations (cleaning, chain problems, punctures, etc.) MUST be carried out
with the motor switched off. Indeed, turning the pedal to put the chain back on if
it has come off will drive the motor if it is not switched off.
For the same reasons, your battery must never be opened. No operations must
be performed without the intervention of a specialist.

Important, this instruction manual only applies to the electrical
characteristicsofyourbicycle.YoumustrefertotheB'TWINuserguide

KEY
Your bike is supplied with battery
security key and a spare. It is
essential to note down the number
of this key on the user guide supplied
with your bike on the day you buy it.
This number is also afxed inside the
battery sheath. You can use this if
you lose both the key and the spare
key in order to have another key cut
in your DECATHLON store.
IMPORTANT:If you ride
with the battery in the
sheath, it is essential to
set your key to "locked"
position.
GENERAL OPERATION OF YOUR BIKE
GENERALOPERATIONOFTHEELECTRICALASSISTANCE
You possess an electrically-assisted bike, which can be used with or without
assistance.
To start up your assistance, press the ON/OFF button.
The assistance on your electrically-assistance bike will only operate if you pedal.
When you brake, your assistance will instantly switch off and will remain off as
long as one or both brake levers are pulled. Your assistance will also switch
off if you exceed 25 km/h and will automatically restart when your speed falls

9
below 23 km/h. In order to preserve your range, the bike is tted with a "power"
limiter which will limit your assistance on steep gradients. During intensive use
and in exceptional weather conditions, the assistance may switch off to avoid
overheating and safeguard the entire system.
Your bike's assistance therefore depends on 4 main parameters:
• pedalling (pedalling sensor)
• braking (braking sensor)
• speed (motor)
• power (motor)
And a parameter for exceptional circumstances:
• the temperature
IMPORTANT: During prolonged use in very hot weather, the
temperature of your controller may reach very high temperatures.
Ensure you do not touch the heat sink located under the front of
the battery sheath.

10
GENERALRULESCONCERNINGRANGE
► Rangeandtyreination
You are advised to inate the tyres to between 3.5 and 4.5 bars. A bike loses on
average 1 to 1.5 bars per week.
IMPORTANT: Insufcient tyre pressure reduces the battery range as the tyre
surface in contact with the ground is greater.

► Rangeanddrivingmode
Like a motor vehicle, a responsible driving style will result in a larger range.
If you allow the bike to "carry" you all the time, your range will be reduced in
consequence.
Thus, by riding exclusively in sport mode at low speed, you will bring the range
down to 50%.

BATTERY AND CHARGER
FIRST USE OF THE BATTERY
Your battery is tted with "intelligent" electronics.
It will be delivered in "sleep" mode in order to economise its consumption
(pressing the battery status button will serve no useful purpose as nothing will
be shown on the LED's).
In order to "wake up" your battery, you simply need to connect the charger: The
battery LED's will light up to indicate that it is now ready for use.
PRECAUTIONS FOR USE
PRECAUTIONSTOBETAKENWITHTHEBATTERY
Do not expose it to temperatures exceeding 60°C

out of sunlight.
INFORMATIONCONCERNINGTHEBATTERY
• Always use your battery between -10°C and 50°C.
• The battery is waterproof and can therefore withstand the rain. However,
high-pressure washing and submerging the battery and the bike in water are
strictly forbidden. Preferably wash using a damp sponge.
• Under ideal conditions, your battery can withstand approximately 300 cycles
(complete charging and discharging cycles). Over time and with use, the
performance of your battery will gradually diminish.
• Under normal usage conditions, your battery is given for a range of 35 km
(for a new battery with one user weighing 70 kg, at an average speed of 18
km/h on at ground.
• The performance of your battery will diminish in low temperatures (*).
• Never short-circuit the battery by connecting the positive and negative
terminals.
• Never try to open, dismantle or insert objects into the battery. If a problem
should arise, please consult your DECATHLON store.
• The effects on the environment are low, as electricity is a clean form
of energy. At the end of its life, the battery must be taken back to your
DECATHLON store to be recycled. You will then be able to replace it.
• Failure to comply with the precautions for use will invalidate the warranty.
(*) All the specications mentioned are valid for a temperature of 25°C. The
performance of your battery will fall with the temperature:
• Loss of approximately 15% at 0°C

Only for use indoors
Do not throw it away in inappropriate containers
Risk of electrocution

17
The electrically-assisted bike has a lithium-ion battery which powers the motor.
Unlike other batteries, it is "memory free".
It can therefore be charged whatever its status may be.
When it is used for the rst time, charge it up fully (100%)
RECHARGINGTHEBATTERY
1. Remove the protective cover on the charging connector located on the side
of the battery.
2. Insert the charger plug into a power socket. The charger LED will light up
green.
3. Then connect the charger to the battery by inserting the charger connector
into its socket on the battery.
4. At the start of charging, the charger LED will go to orange and the LED's on
the battery will light up (according to the status of your battery).
5. During charging, the charger LED will remain orange and the battery LED's
will light up as charging progresses (see the charging indication table
below).
6. Once charging is complete, it will stop automatically. The charger LED will
switch to green and the LED's on the battery will go out 10 minutes after the
battery is fully charged (charging lasts approximately 6 hours).
7. You can then disconnect the battery from its charger and use it.
