1. Introduction
Hermansen e-bikes are pedelecs (Pedal Electrical
Cycles), also called EPACs (Electrically Power As-
sisted Cycles), which means that they are electric
bicycles where the rider’s pedalling is required to get
assistance from a small electric motor. A pedelec is a
low-powered e-bike type where the maximum rated
power allowed is 250W and the maximum motor as-
sisted speed level allowed is 25 km/h.
This manual provides important information about
your Hermansen e-bike’s electrical system, which con-
sists of an intelligent rear hub motor, a bottle shaped
high energy density Li-ion battery, and a smartphone
app from which you control the motor settings and
monitor the battery’s state of charge.
The electrical system complies with all essential
requirements of the Machinery Directive 2006/42/EC
and Directive 2004/108/EC relating to electromag-
netic compatibility. The following technical standards
were used: EN 15194:2017 Electrically power assisted
cycles (EPAC), essential requirements of the Machin-
ery Directive 2006/42/EC and Directive 2004/108/
EC relating to electromagnetic compatibility.
We recommend that you read the manual attentively
and keep it in a safe place for future reference.
We continuously update and improve our e-bikes and
may provide supplementary pages in the future to
ensure that you have the most up to date information.
Please regularly check for electrical system manual
updates at our website www.hermansencph.com in

2. Motor
Hermansen e-bikes are equipped with an intelligent,
brushless and small 250W rear hub motor with built-
in controller, sensor and Bluetooth communication
module. It is a silent <50dB motor with a maximum
motor assisted speed level of 25 km/hr in compliance
with EU regulation. The motor has over-temperature,
overspeed, overload, undervoltage, overvoltage and
other protection functions.
The motor is powered by an external bottle shaped
battery placed on the e-bike’s seat post and
controlled from a Bluetooth connected smartphone
app. For more information about the battery please
see chapter 3. For more information about the app
please see chapter 4.
Turning the motor on and off
When you connect the power cable from the motor
to a charged battery, the motor is turned on. If
you disconnect the power cable from the battery
the motor turns off. The motor also turns off if the
connected battery is discharged.
If the e-bike is left idle with the power cable still
connected to a charged battery, the motor will go into
sleep-mode after being inactive for ve minutes to
save battery. When you start riding your e-bike again
the motor turns back on.
Activating motor assistance
The motor has a pedal action sensor designed to
register when you turn the pedals. The motor only
provides assistance when you pedal, and when
you stop pedalling the motor stops supporting too.
It makes pedalling easy and feels like riding with
constant tail wind.
DANGER!
Note that a pedelec moves
immediately when you put your foot on
the pedal and it sets in motion. Always
rst pull the brakes and then get on
the e-bike. Otherwise an unexpected
move can lead to hazard and injury.
Motor assist settings
The motor has four power assist settings which you
set from the smartphone app:
• Off: Zero power assist
• Eco: 40% of maximum power assist
• Tour: 70% of maximum power assist
• Sport: 100% of maximum power assist
When you start pedalling the motor starts to assist
you if you have chosen the Eco, Tour or Sport
setting. It will support you until you reach the allowed
maximum motor assisted speed level of 25 km/h. You
may also set the maximum motor assisted speed at
a lower level on the app. This means that the motor
will cut off at this speed level but start assisting your
again if your speed falls below 25 km/h. For more
information about how to set up the motor from the
app please see chapter 4.
Riding your e-bike
Before riding your e-bike for the rst time you must
set up various motor and riding parameters in the app.
For more information about how to set up the motor in
app please see chapter 4.
The default power assist setting is Eco. This means
that if the e-bike has been turned off it will default to
the Eco setting when connected to a charged battery
again and you start riding your e-bike.
If your bike is in sleep-mode and you start riding your
e-bike again, the motor will reactivate and start to
support you with the latest chosen power assist level.
If you choose the Eco power assist setting, the
motor may not be able to get you to reach 25
km/h, depending on riding conditions, riding style,
cargo load and rider weight, unless you pedal with
considerable power yourself. In this case switch to
a higher power assist level if you want to increase
support and speed.
• When driving uphill and headwind, you can
increase the power assist level to get an easier
ride.
• Riding uphill for a long time with maximum
motor assist may activate the motor’s overheat
protection in which case the app will show an
overheat warning message. If this occurs, turn off
the motor and wait until the temperature drops.
When the temperature drops, the motor will
automatically return to working normally.
• After riding, store your e-bike in a proper place.
• If the bike is stored for a long time, disconnect the
power cable and avoid storing the e-bike near a
heat source.
Cleaning
Never use pressurised water, spray or steam to
clean your e-bike because water can be forced into
sealed areas and damage components like the motor,
cassette body, bearings and other parts.

7
When your e-bike needs cleaning, use a bucket of
water and gently sponge off any accumulated dirt and
salt from your bike. Dry your e-bike after cleaning to
prevent rusting.
Always disconnect and remove your battery before
cleaning your e-bike.
DANGER!
Damage to your e-bike’s electrical
system caused in any manner,
including water intrusion, can lead
to battery failure, electrical system
malfunction and electrical re and
cause property damage, injury, or
death. Follow all recommendations to
minimize risk of water damage.
Precautions
• Do not disassemble the motor, or you may risk
irreversible damage.
• Do not loosen or remove the screws and nuts on
the motor.
• Do not expose the motor, cables or batteries to
rain, snow, high temperature, and high humidity
for a long time.
• When using the motor, do not ride through water
or areas with snow, in order to avoid danger.
• When using the motor, do not violently impact the
motor, in order to avoid internal motor failure.
• Do not immerse your motor into water.
• Do not put the motor in ammable, explosive,
corrosive and other gas environment.

3. Battery
The battery that powers the motor is an external
bottle shaped battery placed on the rear side of
the e-bike’s seat post. It is a Li-ion battery with
Panasonic NCR Series 18650 cells and BMS battery
management system. As at the date of this Manual it
is the highest energy density battery on the market.
The battery can be charged ≥500 times thanks to its
protection functions for undervoltage, overcurrent,
short circuit and over voltage. The battery’s charge
status can be monitored on the smartphone app,
which is used to set and control the motor. For more
information about the app please see chapter 4.
Battery components
The battery comes in a polished stainless steel casing
with a black ADS reinforced carbon bre cap. The
cap has a handle placed asymmetrically to one side.
The handle can be convenient when the battery is
detached from the e-bike and you need to carry it.
The handle can also be used to x a wire lock to
secure the battery from theft when the e-bike is not in
use.
A strong magnet is placed inside the battery casing to
the same side as the battery cap handle. The magnet
is for attaching the battery to the battery mount.

Charger
The e-bike is delivered with a charger which is
developed especially for Li-ion batteries used for
e-bikes. The charger has a LED light indicator, which
turns from red to green when the battery is fully
loaded.
Do not use another type of charger to charge your
e-bike battery, even if the plug ts.

Attaching the battery
The battery is xed to the e-bike’s seat post with a
battery mount that has a magnet and a Velcro strap.
This battery mount magnet pairs with the magnet
placed inside the battery casing. To ensure a correct
magnet snap, always align the battery magnet side
(the cap handle side) with the battery mount magnet
when attaching the battery to the e-bike. When
correctly aligned you clearly feel the magnet snap.
Subsequently, you must tightly wrap the black Velcro
strap around the battery and close it rmly to protect
the battery from skipping off if you ride on uneven
surfaces or make sudden turns or stops. We also
recommend that you place the power cable from the
motor between the battery and the Velcro strap to
keep it rmly in place when connected to the battery.

To detach the battery from your e-bike simply open
the Velcro strap, detach the power cable from the
battery and grab the battery.
Charging the battery
• Connect the power plug (5) to a turned off power
outlet, connect the charger’s battery plug (4) to
the battery’s charge port (1), then turn on the
power outlet. Connecting the charger’s battery
plug to the battery’s charge port with the power
outlet turned on may generate a spark between
the battery plug and the charge port.
• The charger has a LED light indicator, which
turns from red to green when the battery is fully
charged.
• Charging time is 3-4 hours to charge the battery
completely.
• The maximum charging voltage is 37.8V. Do not
exceed this value.
• Charging current should be under 3A.
• Keep the ambient temperature between -10C to
45C when charging the battery.
• The battery should have room temperature when
charging.
ATTENTION!
Only use an original charger to charge the
battery.
Battery range
The battery range varies depending on factors
such as:
• Average riding speed - the faster you go the more
energy is required and the quicker the battery will
be discharged. However, if you ride faster than 25
km/h or the ‘Maximum speed’ you have set in the
app, the motor assist will shut off and the motor
will not drain the battery.
• Assistance level used - the best way to conserve
battery power is pedalling effort. Using less
assistance and exerting more effort into pedalling
will decrease battery power consumption and
result in a longer range.
• General maintenance - keep your tyres correctly
inated at all times and maintain and lubricate
moving parts.
• Stop-and-go trafc - starting from a standstill will
always require more energy. To extend your range,
start in Eco mode.
• Rider’s weight and cadence - the motor will use up
more energy for heavier riders. Keeping a cadence
of at least 60 rpm will be more efcient.
• Some riding conditions such as uneven road
surfaces, headwinds and going uphill requires
more power to assist you up to a certain speed
and thus reduces the battery range.
Battery capacity
• Batteries, measured in watt-hours, have different
energy capacities. In general, the more watt-
hours, the longer the range, the more expensive
the battery, and the heavier your bike.
• Ambient temperature can have a signicant
impact on battery capacity. Battery capacity is
tested at a reference temperature of 23°C (73F).
Large deviations from the reference temperature
will drain the battery faster due to changes in
internal resistance and will shorten the range.
• As the battery ages its original capacity
diminishes. This is true of all batteries but some
chemistries last longer than others.
• You can always check the amount of charge
remaining in the battery on the app when the app
is connected to a motor turned on.
Precautions
• Do not put the battery in high temperature
environment or direct sunshine.
• Do not disassemble the battery and beware of
impact and fall.
• Do not expose the battery to humid environments
or water.
• Do not put excessive pressure on the battery
• Do not put the battery in metal powder or ionized
environment.
• If you’re going to stop using the bike for more than
a month, charge the battery before storage.
• Charge the battery at least every three months to
keep the battery capacity.
• Never fully drain the battery and never leave it
uncharged for a prolonged period of time as this
may damage the battery permanently.
DANGER!
Remove the battery before any
assembly, maintenance or other work
on your e-bike to avoid unintentional
activation of the electric system which
can cause injuries.

4. App
The motor is controlled from a Bluetooth connected
smartphone app called ‘Keyde’. From the app, you set
the various motor parameters and preferences, view
the motor’s running status, set the power assist level
and monitor the battery charge status.
To download the app to your smartphone please scan
the QR code that ts your smartphone type or go to
your app store and download the app.
Regularly check for app updates in your app store and
update the app accordingly.
Installing the app
The app can only connect with the motor when the
motor is turned on. To set up the app you must:
• Mount a charged battery on the e-bike and
connect the power cable from the motor to the
battery.
• Stand beside the e-bike and lift the rear wheel a
few centimetres from the ground and give the rear
wheel a short spin to activate the motor.
• Open the app and hold you smartphone close to
the rear hub motor.
• Allow Bluetooth access when asked. Do not use
your Smartphone Bluetooth setting to connect.
• Tap ’Search’ and wait for the app to register the
motor.
• When the Bluetooth symbol in the upper left
corner turns from red to blue, the app and motor
are paired.
• If the Bluetooth symbol has not turned blue after
a 5-10 seconds exit and close the app and open it
again. The app and motor should now connect.
Setting up the app
When connecting the app with the bike for the rst
time, you need to set up a number of parameters
and preferences in the app to correctly control and
monitor the motor when riding your e-bike.
Tap the gears symbol in the upper right corner of the
app’s main screen to get to the settings menu and
then set the following parameters and preferences:
• Wheel size: 20” (this is your e-bike wheel size).
• Voltage: 33V (this is the voltage of the battery
delivered with your e-bike).
• Maximum speed: This is the maximum speed level
you want the motor to assist you to. The motor
will automatically cut off at the set speed level.
You can set this preference as you desire but pay
attention to the allowed maximum driving speed
of e-bikes according to local laws and regulations.
• Maximum power: The higher you set the watt,
the stronger the support and acceleration power
but also the higher battery consumption. The
percentage of maximum power assist indicated for
each of the motor’s power assist levels Eco, Tour
and Sport apply to the preference you set here.
• Speed unit: Choose between having your speed
displayed as km/h or Mph.
• Bright display: When this setting is turned on, the
open app stays bright on your smartphone screen
and overrules you general screen lock timer.
• Drive mode on right side: When on, the location of
the power assist modes Eco, Tour and Sport shift
from the left to the right side of the app’s main
screen interface.

• Dark display: When on, the app background colour
turns from bright to dark
• Language setting: Here you can set your desired
language
• Change bicycle: Here you can disconnect from
a paired e-bike. This can be relevant if you want
another rider to use your e-bike and control it from
their own smartphone app. Two smartphone apps
cannot be connected to the same e-bike at the
same time.
• Cycling data clear: Here you can delete the app
history
• Reset: Here you can reset the app to the factory
settings
Operating the app
The app displays various information about your ride,
watt consumption and battery charge status. You may
nd it convenient to acquire a smartphone mount for
your handlebar to have your smartphone placed easily
visible and accessible at your handlebar.
DANGER!
Never operate the app while your
e-bike is in motion as this prevents
you from carfully paying attention to
your surroundings which may result in
an accident which can damage your
e-bike and cause serious bodily injury.
On the app’s main screen you can monitor the
following:
• Bluetooth icon: Shows the Bluetooth connection
status. When red, the app and motor are not
connected. When blue, the app and motor are
connected.
• Battery icon: Shows the charge status of the
battery. If the battery is fully charged, the icon
shows ve green bars. When the battery is close
to being discharged, the icon shows one red
bar. The number of green bars can vary a little
depending on riding conditions. For example,
when riding uphill the number of bars may go
down by one and then go back up one bar when
riding downhill immediately after.
• Speedometer: The number in the middle shows
your running speed. The green left side of the
circle shows your relative speed. The red right
side of the circle shows your relative power
assist level. ODO in the lower part of the circle
shows your total distance travelled while the app
has been connected to the motor without any
disconnections.
• AVS: Shows your average speed for your current
ride.
• MXS. Shows your maximum speed for your
current ride.
• TM: Shows the time passed for your current ride
• TRIP: Shows the distance travelled for your
current ride.
• Power: Shows the running power assist in watts.
• TEMP: Shows the motor temperature.
• The buttons Off, Eco, Tour and Sport lets you
choose your desired power assist level. Please see
chapter 2 about the motor for more information
about the power assist settings.
The app can only monitor your ride when open as the
primary app on your smartphone screen. It is not able
to keep running in the background if you open and
use any other app. For example, if you have not turned
on ‘Bright display’ in the app settings, the app stops
monitoring your ride if your screen locks according
to your general smartphone ‘Automatic lock’ settings.
This is also the case if you make or accept a call on
the phone. The app will in those instances cease to
meassure the time span of your ride.
