All users must have read and understood the instructions and information outlined in the manual.
If, during assembly, any factory defects are detected, certain steps are unclear or issues with assembly or adjustments occur,
do not ride the vehicle and contact your dealer or visit www.argentobike.it for for technical support.
CAUTION
Risks associated with using the electrically power assisted cycle
Despite the application of safety devices, to ensure safe use of the electrically power assisted cycle, all the safety provisions
reported in this manual must be observed.
Always maintain concentration while riding and do not underestimate the residual risks connected with use of the electrically
power assisted cycle.
CAUTION
Responsibility
The driver is obliged to use the product (pedal-assisted bicycle – EPAC) with the utmost diligence and in full compliance with
all the cycling regulations in force in the country of circulation.
The product, according to the provisions of the Regulations in force regarding the conditions of conformity relating to
EPAC products (EN 15194), cannot be used on public roads, but only for exclusive use in a private area and under the direct
responsibility of the end user.
It is important to note that when using the product, even following this manual to the letter, you are not immune from injury
caused by violations or inappropriate actions taken against other vehicles, obstacles or people. Misuse of the item or non-
compliance with the instructions provided in this manual may cause severe injury.
Riders must also ensure that the electrically power assisted cycle is kept clean, in perfect working order and serviced. They
must diligently carry out the safety checks which are their responsibility, as well as preserve all the documentation about
product maintenance.
Riders must carefully assess any weather conditions which could make it potentially dangerous to use the electrically power
assisted cycle.
This product is a vehicle, therefore, the faster is it goes, the longer the braking distance required. We, therefore, recommend
moderating your speed and maintaining an adequate braking distance if you are riding in adverse weather conditions and/
or heavy trac.
The braking distance increases on wet, slippery, muddy or icy roads and the tyre grip decreases significantly with the risk of
the wheels skidding and loss of balance compared to dry roads.
It is, therefore, essential to ride the bike with greater care, maintain a suitable speed and safety distance from other vehicles
or pedestrians.
Take extra care when riding on unfamiliar roads.
For your safety, we recommend wearing suitable protective equipment (helmet, knee and elbow pads) to protect yourself
from any falls or injuries while riding the bike. When allowing others to use the bike, ensure that the rider wears the safety
equipment and explain how to operate the vehicle. To avoid injury, do not allow other persons to use the item if they do not
know how to use it.
Wear shoes before using the item.
The bike has been designed to allow the load of a maximum overall weight (rider and any load being carried) that does not
exceed the value indicated in the product data sheet.
Avoid using the product, under all circumstances, if the total load transported exceeds the recommended weight to avoid the
risk of damaging the integrity of the structural and electronic components of the bike.
The electrically power assisted cycle is a means of transport used to transport only one person.

04
It is the user’s responsibility to ascertain the suitability of the devices used for passenger transport in terms of construction
characteristics, safety systems, anchoring systems and their installation and assembly on the electrically power assisted cycle
based on its structure and within the permitted load limits (maximum load supported by the bike and by the luggage rack
supplied, if present).
The user is also responsible for the equipment and installation of product equipment devices used for the transport of objects
and animals (e.g.: luggage racks, luggage bags, baskets, etc.) and within the expected load limits (maximum load borne by the
product and the provided luggage rack, if present).
CAUTION
The installation of accessories and equipment on the bike, not only aect the performance of the bike and how it is used, but
can also cause damage if they are unsuitable, thus compromising correct operation and safety conditions during use.
For information on the supply and installation of equipment deemed suitable for the bike, please contact your authorised
dealer or specialised operators.
Warnings for users
• The electrically power assisted cycle can only be used by adults and skilled teenagers.
• Do not take alcohol or drugs before riding the electrically power assisted cycle.
• This model of electrically power assisted cycle is designed and built to be used outdoors and exclusively in private areas.
• Do not attempt to make the electrically power assisted cycle exceed the performance levels for which it was designed;
do not ride on surfaces with a slope greater than 10%, on uneven and rough ground (bumpy road surfaces, with potholes,
depressions, obstacles).
• Never ride the electrically power assisted cycle with any of its parts disassembled.
• Avoid uneven surfaces and obstacles.
• Ride with both hands on the handlebars.
• Before use, replace any worn and/or damaged parts and check that the safety devices are working properly.
• Keep children away from plastic items (including packaging materials) and small parts that may result in suocation.
• Supervise children to make sure they do not play with the product.
• Remove any sharp edges caused by misuse, breakage or damage to the item.
• Pay particular attention when riding the bike near pedestrians and make sure you slow down and signal your presence to
avoid frightening them when arriving from behind.
• Assemble the item correctly.
CAUTION
How to use
The electrically power assisted cycle is a bicycle fitted with an auxiliary electric motor that is activated only when the pedals
are turned.
The motor does not, therefore, replace the work performed by your leg muscles, but assists them so they work less hard by
enabling the electrical and electronic components supplied with the product, i.e. the battery, handlebar controls, sensors and
control electronics (control unit).
More specifically, the electric motor is powered by a battery and operated by a unit that controls the delivery of power and
additional thrust provided to assist the eort made by the rider’s muscles when pedalling based on the real-time reading of
values detected by a series of pedal-assist sensors (PAS). These sensors are positioned on the outside of the frame or inside
the components and are based on the control parameters entered by the user via the handlebar controls (display).
The electric motor supplied with the pedal-assisted bicycle, in addition to being activated exclusively in support of the muscle
pedaling function provided by the user, will deactivate when reaching 25 km/h of speed.
The electrically power assisted cycle has been designed and built to be driven outside, on paved surfaces and/or terrain
suitable for the specific technical and structural characteristics of the product.
Any changes to its construction may compromise the behaviour, safety and stability of the electrically power assisted cycle
and may cause an accident.

05
Any other types of use, or any extensions of use beyond the one intended, do not correspond to the intended use attributed
by the manufacturer and the latter, therefore, disclaims all liability for any resulting damage.
The autonomy of the battery supplied with the electrically power assisted cycle and, therefore, the relevant distance data
estimated in km, may vary significantly depending on the specific mode of use (total load transported, how hard the rider
pedals the bike, level of electric pedal assistance detected, how often the rider departs and restarts), the mechanical and
electrical conditions of the product (tyre pressure and wear, battery eciency level) and external influences (slopes and road
surface, atmospheric conditions).
Before each use, carefully check that the brakes are working correctly and are not worn; check the tyre pressure, the wear of
the wheels and battery charge status.
Regularly check that the tightness of the various elements secured by bolts. The nuts and all the other self-tightening parts
can become loose so, these components need to be periodically checked and tightened.
Like all mechanical components, the item is subject to wear and tear. Dierent materials and components may react to wear
or stress fatigue in a variety of ways. If the useful life of a component is exceeded, it could break suddenly, causing injury
to the user. Any cracks, scratches or changes in colour in areas subject to high levels of stress indicate that the life of the
component has been reached and must be replaced.
CAUTION
Any changes to the control unit which have not been authorised by the manufacturer will exclude the latter from any liability
related to injury caused to persons and/or damage to property, and will invalidate the bike’s warranty terms and conditions.
DANGER
Risk of injury
Maintain a speed and a behaviour appropriate to your abilities to avoid causing serious damage and injury to yourself or to
other people.

5. Assembly
Carefully remove the bike from the packaging* and remove the protective material taking care not to damage the relevant
aesthetic parts or force the cables and pre-assembled components.
*The bike must be removed from the packaging by two adults to ensure that it is not damaged and avoid the risk of injury
and/or crushing.
Front wheel positioning
Check the correct positioning of the front wheel.
The proper orientation of the front wheel will be confirmed by verifying the correct location of the front light (positioned
frontally) and the front wheel brake disc (positioned on the left side of the front wheel).
Otherwise (fig. A), rotate the front wheel clockwise 180° until it is aligned with the frame, taking care not to force cables and
pre-assembled components (fig.B).
fig. A fig. B
Positioning the handlebar stem
Raise the handlebar stem until it is vertical; tighten the handlebar stem using the locking device indicated by the letter A.
Positioning the handlebars
Position the handlebars on the handlebar attachment taking care to centre and adjust them correctly so they slot onto the
controls, tightening the handlebar attachment lever (tightening device between the handlebars and handlebar attachment).

10
5. Assembly Handlebar stem plate assembly/disassembly instructions for handlebar installation/removal (if necessary)
Remove the handlebar stem from the top end of the
handlebar attachment as follows:
Remove the screw number 1 and then the lever number 2.
Then, remove the metal plate 3 and lastly, remove the
metal plate 4 by sliding it sideways.
Now put the previously removed handlebar stem back in
place, following the steps in reverse order.
Make sure to tighten properly to avoid dangerous
situations while riding.
Installing and positioning the seat post
Insert the seat post into the seat tube of the frame and, after positioning the saddle correctly, secure the seat post firmly using
the special clamping device (seat post clamp) on the frame.
DANGER
Minimum insertion seat post insertion limit
For structural and safety reasons, it is strictly
forbidden, when using the bike, to extract
the seat post from the seat tube of the frame
beyond the limit indicated on the latter to avoid
the risk of causing any structural fractures to the
bike and incurring serious injuries.
The seat post is deemed to be correctly and
safely positioned inside the seat tube of the
frame by inserting it so that no markings and/or
graphic indication of the minimum insertion limit
can be seen; see:
Correct position Incorrect position

11
Maximum insertion seat post insertion limit
For structural reasons, to prevent the risk of damage and
to allow proper operation of the spring-loaded rear shock
absorber that connects the saddle column tube and the
vertical frame sheath, it is strictly not recommended to
insert the seatpost groove beyond the lower limit of the
column tube until any contact, or proximity of contact, with
the shock absorber.
Adjust and verify the presence of a suitable distance
between the aforementioned components to ensure
an adequate operating margin commensurate with the
supported load (see: user weight).
Installing the pedals
Locate the right pedal (marked with the letter R) and left pedal (marked with the letter L).
Fit the right pedal (R) by inserting the threaded pin of the pedal into the corresponding crank arm on the right side of the bike
and screwing it clockwise (turn it towards the front wheel) until it is tightened using a 15mm wrench.
Fit the left pedal (L) by inserting the threaded pin of the pedal into the corresponding crank arm on the left side of the bike
and screwing it anticlockwise (turn it towards the front wheel) until it is tightened using a 15mm wrench.
CAUTION
Verify and regularly check that the various bolted elements, fastening screws, quick releases and pass-through pins are
correctly tightened, and perform an overall check to ensure that all the parts are in order.
The nuts and all the other self-tightening parts can become loose so, these components need to be periodically checked and
tightened.
The recommended tightening torques for fastening the specific parts/components on the bike (e.g. handlebars, handlebar
attachment and stem, saddle, saddle clamp, wheels, etc.) can be identified depending on the relevant elements. An average
torque of 20Nm can be used for all other fastenings.
Verification of the correct tightening of the parts/components through lever systems (quick release, handlebar attachment,
seatpost collar, etc.), in the absence of technically precise indications of the relative values, can be done by testing that the
relative part/component being fixed is not mobile and/or unstable if subjected to a vigorous attempt to remove and/or extract
(handlebar, seatpost channel, wheels, etc.) and by verifying that the tightening lever has adequate resistance during the
closing phase (such as to leave a mark on the palm of the hand used for lever tightening, so-called "imprint on palm") and,
after closing, requires a considerable force to be exerted to allow relative opening.
Rear light
The rear LED light is already installed on the end of the rear luggage rack.
It can be switched on and o manually using the button on the light itself or, at the same time as the front LED light is switched
on/o via the control on the display, if this option is included.

12

Indicator light for residual battery charge
The battery charge level is shown on the display screen as a number of dashes between 0 and 5.
If there are 5 dashes, it means that the battery is charged to the maximum percentage defined and detected instantly.
Less dashes are shown to indicate a decrease in the battery charge level available and subsequent autonomy.
The level of the battery charging indicator may fluctuate depending on how the electrically power assisted cycle is being
used, for example, when going up a slope, the level displayed can drop rapidly as there is a much higher battery consumption.
The individual dashes indicate the specific battery charge range detected at the time and do not necessarily indicated a
percentage of the residual autonomy.
