3.5. HOW TO USE THE DEVICE (READ BEFORE FIRST USE)
HELMET WEARING
We strongly advise you to equip yourself before riding the bike with at least
one helmet, which must comply with the regulations on personal protective
equipment and must be attached.
WARNING: The user must comply with the requirements of national
regulations when using the bicycle on public roads, including compliance
with the Highway Code.
WARNING: The user is obliged to install lighting, signalling and warning
devices on the bicycle.
-It is forbidden to ride on the sidewalk, otherwise the bicycle must be held

EN
16
in the hand.
-Do not wear earphones or any device that may emit sound, or use a hand-
held telephone.
The wearing of a certified retro-reflective vest is mandatory for all cyclists
and passengers riding outside the city at night or when visibility is poor. The
manufacturer declines all responsibility if the driver of the bicycle does not
comply with the regulations in force.
3.6. FIRST USE
Before each use, please check the general condition of your bike.
The good condition of wearing parts such as brakes, tires, steering,
transmission, rims, etc. must be checked by the user before every use and
regularly checked, serviced and adjusted by a qualified mechanic.
Be sure to properly maintain your bike according to the instructions in the
user’s manual.
The ideal temperature range for the use of electric bicycles is between 5 and
25°C. Using your electric bicycle in low temperatures, less than 5°C, will not
damage your battery but may reduce performance.
The device emits an average sound pressure of less than 70dB at the user’s
ears.
WARNING: Like any mechanical component, a bicycle is subject to high
stress and wear. Different materials and components can react differently to
wear and fatigue. If a component has exceeded its service life expectancy, it
may break off in a single blow, possibly causing injury to the cyclist. Cracks,
scratches, and discoloration in high stress areas indicate that the component
has exceeded its life expectancy and should be replaced.
1. Check that the battery is securely in place and locked with the key in the
«LOCK» position.
2. Turn on the unit by pressing the ON/OFF button on the control panel.
3. Start pedaling like a regular bicycle.

EN
3.7. HOW TO REMOVE AND REPLACE THE BATTERY
1.To remove the battery, switch off the unit, unlock the battery with the key (1)
and remove the battery case by lowering and pulling the handle (2).
2.To replace the battery, place the battery back in its place (with the battery
lock facing down), lock the battery with the key and then pull the battery
handle all the way up.
3.8. ASSISTANCE, PARKING AND AUTONOMY
Pedaling assistance :
The bike is equipped with an electric pedaling assistance. The motor, located in
the hub of the rear wheel, starts once the user starts pedaling and completes
his efforts. The operation of the electric assistance depends on the speed of
the pedals and the speed of the bicycle. As stipulated by current European
legislation, the 250W motor stops at 25 km/h and switches off as soon as the
user stops pedaling.
To increase or decrease the power of the motor and therefore of the electric
assistance, press the + or - button on the control panel.
Parking :
- Turn off the power by pressing the ON/OFF button on the control panel.
-Lock the battery with the key or remove it and take it with you when the unit
is not in use.
-It is advisable to attach the unit when not in use to prevent theft.
-Never park the unit outside when it rains or snows. Prefer a garage that is
dry and well ventilated. After a trip in rain or snow, take the unit to a sheltered
place and wipe off any moisture with a clean, dry towel.

Mileage/Autonomy :
Many factors affect the rate of electric power usage and range as outlined in
Part 4.
In order to maximize the range of your unit, it is important to take note of the
following points:
- Fully charge the battery before a long trip.
-The advertised autonomy is measured under optimal conditions of use. User
weight, driving speed, rough roads and hilly terrain, tire pressure, headwind,
frequent changes in speed and braking (in town) and outside temperature are
all factors that affect the range of the device.
- Driving with properly inflated tires and a clean, well-lubricated unit saves
energy.
-Regularly check the brake settings and make sure both wheels are moving
freely (that the brakes do not rub the wheel while driving).
- Battery capacity decreases as it ages.
9. SPEED LIMITS
The product is designed to travel at a maximum speed of 25 km/h.
Ensure you are following the usage restrictions of this product in terms
of the road safety norms of the country where you are using it.
10. DRIVER WEIGHT
The driver’s weight cannot exceed 120 kg.
Note: not respecting this weight limit increases the risk of falling or
damaging the product.
4. MAINTENANCE AND CLEANING
1. BATTERY
The capacity of lithium batteries decreases after several charging and re-
charging cycles throughout its lifespan. The concept of life cycle exists for
lithium batteries (for example, about 300 on a scooter).This means that from
300 COMPLETE cycles of charges and discharges, the battery will begin to
lose its capacity (similar to a smartphone battery).
This partial loss of capacity will not prevent the battery from functioning, but
will alter its performances and especially its operating life.
The device must be used and its battery recharged at least once a month: a
lithium battery will lose its charge even when the product is off. This is why a

EN
19
battery that has not been charged for several weeks or less could lose some
of its capacity and become impossible to recharge.
In addition, it is possible to recharge a lithium battery after each use because
there is no memory effect.
WARNING: charging the battery must only be done indoors or in a place that
is protected from weather (rain, snow, excessive heat...)
In order to better preserve your device’s battery, here are some reminders
and instructions for use:
•Do not unplug the charger before the battery is fully charged.
•Store the product containing the battery in a cool place (temperature
> 0°C), preferably around 15°C. Be careful, as excessive heat will also damage
the battery.
•Avoid deep discharges.
•Avoid recharging the battery right after use. Allow the device to rest for
between 15 minutes and 1 hour after use before charging.
•Avoid overloads. Do not leave the charger plugged in for more than 24 hours,
as it will heat up needlessly.
Notice: We recommend recharging the battery, if not in use, after each use
and at least once a month.
Important: If you are not near a charging point when the battery is down to its
last quarter, we recommend switching to eco mode.
Tip: As you drive, the battery level indicator on the display may suddenly de-
crease depending on your driving style and conditions (heavy use of the ac-
celerator, riding uphill, outside temperature below 10°C, etc.). Be aware that
the actual battery level displayed will be most accurate when the device is
turned off.
4.2. INSPECTING AND MAINTAINING YOUR DEVICE
Your product requires routine inspection and maintenance. This chapter de-
scribes maintenance and operation steps. Before performing the following
operations, make sure that the power is off and that the charging cable is
unplugged. Before each use, carefully check:
•The tightness of the handles.
•That the wheels are functioning properly by lifting the device and running
the wheels idle.
•The column, the steering tube, nothing must prevent it from turning. The
entire steering system must be correctly adjusted and all connecting

EN
20
elements and screws tightened and in good condition.
•Check the tightness of the screws, the front and rear wheels, shock
absorbers, and bonnet, and tighten again if necessary. These adjustments
may be needed because of vibrations caused by using the device.
•The condition of the tyres. Tyre pressure if the unit is equipped with air
wheels, and inflate as soon as is necessary using a bicycle pump or similar.
•The brakes, drum linings, brake pads, foot brake, depending on the unit. If
the unit is equipped with mechanical brakes (disc, drum, foot), ensure they
are not rubbing due to cable tension or exhibiting any other problems, as this
may cause the unit to slow down and prevent it from operating normally.
Overheating may impact the brake’s efficiency.
•Check that the electric brake is functioning properly if the unit is equipped
with one.
If after adjusting you notice looseness that may affect your ability to drive
safely, or if an unusual noise appears, or a lack of fluidity is apparent, stop
using the unit and contact your dealer for more information or care.
If the product, a component, or the battery are worn out, please contact an
authorised service centre to repair or recycle your product.
MAINTENANCE AND SPARE PARTS :
Your bike requires regular maintenance for your safety but also to increase
its life span. It is important to check the mechanical components periodically
to ensure that worn or worn parts are replaced if necessary.
The battery must be removed before each maintenance operation.
WARNING: When replacing components it is important to use original parts to
maintain the performance and reliability of the bicycle. Only manufacturer’s
parts are considered original parts.
WARNING: It is the responsibility of the user in case of purchase and use of
fake (counterfeit) parts that subsequently cause damage to the product,
person or environment.
Make sure to use appropriate spare parts for tires, inner tubes, transmission
elements and various components of the braking system. If you have any
questions, please contact the service department or your dealer.
The manufacturer cannot be held responsible for improper use or incorrect
installation.
WARNING 1 : Like all mechanical components, EPAC is subject to wear
and high stress. Different materials and components can react to wear
or stress fatigue in different ways. If acomponent’s rated life has been
