Getting started and safety check of your Y Muse 25EC Declaration of Conformity CE
. Getting started and safety
check of your Y Muse 
Although your E-bike has been subject to a final check on
the assembly line as well as by your local Klever dealer,
the transport and time may have caused changes in
its functionality. Therefore, prior to your first ride and
occasionally thereafter, you should consider to check
following points:
• Make yourself intensely familiar with the Y Muse 25 and the
functioning of its electric motor support, before the first ride
in public trac.
• Setting of the saddle and the handlebars.
• Function of the brakes.
• Air pressure and the depth of the thread pattern of the tyres.
• Proper operation of the lighting system.
• Tightness of the bolts and nuts of the wheels.
• Minimum insertion of the seat post.
Caution! Do not start when you identify deficiencies in
one of these points. While riding a defective E-bike this
can cause serious accidents and endanger your life. If
in doubt, please contact your dealer or our technical
hotline.
Caution! Your bike suers wear and tear in everyday
riding through extreme weather and road bumps.
Through constant dynamic loads dierent parts of the
bike experience dierent material fatigue and wear.
Therefore, it is recommended to inspect your Y Muse 25
on a regular basis and look for wear of parts and changes
in scratches or cracks, or the discolouring of parts. These
could possibly indicate damage of the part. Needless to
say, that damaged parts must be repaired or replaced.
Please note! Following the inspection plan in section
19, you best bring your E-bike to your Klever dealer for
inspection, service, maintenance and repair.

Behaviour in road trafficGetting started and safety check of your Y Muse 25
. Behaviour in road trac
Thanks to the electric auxiliary propulsion you reach high
speeds and accelerate faster and easier than you are used
to with a regular bike. Therefore, you should intensively
familiarise yourself with the Y Muse only on a trac-calmed
road before you go in public trac. During riding on the road,
you should follow these tips:
• Though it is not compulsory, we strongly recommend to
always wear a helmet during riding.
• Make yourself familiar with the trac rules and stick to the
rules.
• Be ready to brake at any time and expect misconduct of
others.
• Ride defensively and be considerate to other road users.
• Always keep your Y Muse 25 in a perfect condition.
• Use your bike only in accordance with its intended purpose
(see section 13. Intended use).
• Don´t use a mobile phone nor a headset while riding.
• -Be sure to observe the maximum weight of cyclist + Y Muse
25 + luggage of 150 kg (see section 11. Technical Data).
• Have your E-bike checked according to the recommended
service intervals by authorised Klever dealers.
Please note! Make sure to only use original Klever spare
parts. In case you are not sure whether to use certain
spare parts or not, please always contact your ocial
Klever dealer or otherwise call our technical hotline.

The BIACTRON systemThe BIACTRON system
The five (dierent) levels of motor support can be selected
according to the external circumstances (e.g., climbing uphill
or with headwind) or to your personal preferences. Please
note that a higher level of motor support consequently
means a higher battery consumption and reduces the range
of system and battery.
In case you ride faster than 35 km/h (e.g., downhill),
automatically the recuperation of pedal energy (i.e., technical
regeneration) will be activated. The motor operates as a
generator and partly re-charges the battery. The recuperation
of pedal energy and battery capacity = REGENERATION will
be explained in section 6.3.
.. Sensors and their function
The Y Muse 25 is equipped with a torque sensor in the frame’s
rear dropout. This sensor accurately measures
the force you exert during pedalling. In conjunction with
the pedal sensor, this torque sensor precisely monitors
the cycling eort of the cyclist. The motor controller then
calculates these values and manages precisely the amount of
support from the motor. Hence generating a perfect synergy
between cyclist and Y Muse 25.
You can also define the amount of motor support by yourself
choosing between the ascending levels of support (N, ECO,
TOUR, MAX, TURBO). This makes the system very ecient
and economic, saving power consumption and maximising
range.
The additional speed sensor sets the power of the electric
motor to zero once you have reached a speed of 25 km/h or
more. Above 25 km/h this E-bike functions like a conventional
bicycle, the only way to maintain the propulsion of the
vehicle is by pedalling solely.
The electric motor support only kicks in when you actively
pedal. Therefore, from a standstill to get started either you
have to pedal or you have to actuate the á(TURBO) button
on the display. From standstill without pedalling the motor
will take you to a maximum speed of 4 km/h. The á(TURBO)
button was also designed as an aid when starting uphill or in
case the bike has to be pushed while walking alongside the
bike.
. Klever’s proprietary electric
propulsion  the BIACTRON
system
You have purchased an E-bike that helps you improve your day-
to-day mobility with its electric propulsion. Slopes can be better
managed and the wind resistance can be better overcome.
Klever’s electric BIACTRON system consists of the following
components:
1.Rechargeable battery
2.Motor
3.Control unit / Display
4.Motor controller
5.Torque sensor
6.Pedal Sensor
7.Charger (image 7)
Once you turn on the system and you start pedalling, the
motor will support you as long as you pedal up to a maximum
speed of 25 km/h.

www.klever-mobility.comwww.klever-mobility.com16 17
Please note! These 3 options will only function while
you keep the á(TURBO) button pushed. As soon as you
release the á(TURBO) button, the electric motor support
will stop. Except in the latter case of pedalling: in that
case after releasing the á(TURBO) button the level of
electric motor support will go back to the preselected
level (TOUR as in the example of scenario 3).
In order to save battery power, the support level will
automatically be limited to the TOUR level when the battery
capacity drops to 10%. When the battery capacity drops to 5%
the support level will be limited to the ECO level and in the
case of a battery capacity of 2% or less the level will be N.
. Recuperation of battery capacity:
regeneration
The BIACTRON system of your Klever electric bicycle has an
innovative, unique function: the recovery of battery capacity, also
known as regeneration. Every time the drive system goes into
freewheel mode, the BIACTRON system will start braking the
motor. As a consequence, the motor friction is being converted into
electricity that is stored in the battery.The freewheel model will be
activated once you do not pedal and roll out to a traffic light or you
roll down a hill or mountain without having to pedal.
Section 6.4.3 (menu for settings) explains how this function can
be activated and adjusted to your personal preferences.The
regeneration function is a nice and clean addition to the capacity,
consumption and range of your battery.The more and longer you
ride in a mountainous environment,the more you will benefit from
this function. However, the recovery of electricity is limited and
depends to a large extent on your riding behaviour, the environment
where you ride and the chosen regeneration settings.
. Levels of electric motor support
Our BIACTRON-system oers five levels of electric motor
support:
• N
• ECO
• TOUR
• MAX
• TURBO
Depending on topography, weather conditions and your
personal preferences, you can choose the motor support using
↑ (Up arrow) and ↓ (Down arrow) button and the á(TURBO)
button.
System level Amount of support Situation (recommended)
N No support, electric system
active
Downhill
ECO Low support Flat roads
TOUR Medium support Slight hill / headwind
MAX Strongest support Steep hills / fierce headwinds
á(TURBO) (MAX) while
pedalling < 25 km/h.
Strongest support Steep ramps / violent gusts
á(TURBO) (MAX) without
pedalling < 4 km/h.
Strongest support Starting from standstill
áTURBO) (ECO) walking with Y
Muse < 4 km/h.
Walk-assist, low support Walking with Y Muse or pushing
uphill
Please note! In case you actuate the á(TURBO) button,
there are three scenarios:
1. You walk alongside the Y Muse and/or you push it out
of your garage. While pushing the á(TURBO) button you
will activate the Walk-assist mode and you will trigger
a moderate electricmotor support up to 4 km/h. In this
way you can walk with your vehicle comfortably and
easily.
2. You are sitting on your Y Muse 25 and intend to start
from standstill on a ramp without pedalling. Push the á
(TURBO) button and you will get the strongest support
up to 4 km/h.
3. You are sitting on your Y Muse 25. You are pedalling
with for instance TOUR support and you need the
strongest support momentarily. Push the á(TURBO)
button while pedalling and you will trigger the strongest
support regardless your speed (from 0 to 25 km/h).

trac-calmed street. Once you feel comfortable using
the three á(TURBO) modes, you can start riding your Y
Muse on public roads.
.. Display content
Battery status (image 24)
The battery icon shows the charging status of the battery.
One bar represents 20% of full capacity (half bar represents
10%). If only one bar is shown, only 20% of the maximum
capacity of the battery is available. Now the battery
should be recharged. When the battery icon is half of a bar
only, there is less than 10% battery capacity remaining so
recharging of the battery is urgently needed.
Display Capacity level
5 bars light up green 100%
4 bars light up green 80%
3 bars light up green 60%
2 bars light up green 40%
1 bar lights up orange <20%
Half of a bar lights up red < 10%
Additionally, you can check the charging status with the LED
on the front side of the battery too. To save battery capacity,
it is not possible to choose support level MAX if 10%, or less,
battery capacity is left. With 5% or less capacity remaining,
only the ECO level of support is available. At 2% remaining
battery capacity the system will switch to level N. Meaning
that you will not have electric motor support any ore, but the
system (display & lighting) will remain functioning.
Support level (image 25)
The bars in the upper part of the screen show the selected
level of motor support. See section 6.2 for the various levels
of electric motor support and the recommended riding
situation.

. Rechargeable battery
Your Y Muse 25 has a high-quality lithium-ion battery of the
newest generation. For technical details, please refer to
section 11. Technical data.
The status of the battery can always be checked through the
LED light button, next to the charging socket of the battery
(image 30). Press the button and the LED will light up either
red, yellow or green. If no light, then the battery could be
broken. Please have your local dealer check the battery.
Red Capacity <35%, battery should be charged
Yellow Capacity 35 -75%, battery can be charged
Green Capacity >75%, battery can be charged
The battery is automatically protected from overheating,
overcharging and deep discharging. It is very user-
friendly, very practical, very easy and simple to handle.
Nevertheless, you should consider some important things
in order to maximise the life and performance of the
battery.
Since the lithium-ion battery has no memory effect, you
can charge it at any time, even if it is not completely
discharged. In practice, it has been shown that it is even
better to charge it again after short distances. Your battery
has a lifetime of 700 charging cycles. One charging cycle
means a full charge of the battery (0-100% capacity).
Partial charges can be done more often.
When the battery is not being used for a long time (more
than 2 months), it should be recharged as a low amount of
self-discharge is common. Store the battery, if possible, in
a dry, cool and dark place. The ideal storage temperature
is between 5-20 ° C. Avoid exposing the battery to direct
sunlight over a long time. Temperatures over a longer

Rechargeable batteryRechargeable battery
period of more than 45 ° C or below - 10 ° C can cause
permanent damage. In winter, you should never start with
a cold battery. The capacity of a cold battery is significantly
reduced and consequently will have a lower range. A
battery which is exposed a long time to frost, should be
gently heated in the ambient temperature of a heated
room, before starting.
Caution! Never place the battery on the heater and never
try to heat it with a hair dryer.
In case you need to park your Y Muse 25 outside for a long time
during the cold season, remove the battery and store it in a
heated room. Since the battery is very easy to remove, this will be
no problem. Do not expose the battery to humidity, to prevent
corrosion of the charging socket and the plug contacts. Protect
the battery against mechanical damage and don´t drop it.
Mechanical damage can also cause overheating and the battery
could catch fire.
Also, the battery should be charged at moderate temperatures
(15-25 ° C). Avoid charging in direct sunlight or near heaters, as
well as charging outside in winter at low temperature. A cold
battery should be gently heated to room temperature before
charging.
Caution! Charge the battery exclusively with the proprietary
and dedicated Klever charger which comes with the Y Muse
(image 31).
Do not use any other type of charging unit since this may
damage the battery and may cause overheating or fire.
During charging, neither the charger nor the battery should
be exposed to humidity, in order to prevent short circuits
and electric shocks.
The battery is maintenance-free. Should it be broken
or become defective contrary to expectations, seal the
contacts with tape and take it to your dealer or contact our
technical hotline. Never under any circumstances open up
the battery yourself. This is dangerous and could damage
the battery and it may even catch fire. The warranty will be
void if you do so!
Do not dispose of the battery into household waste. It
must be disposed of properly. It's best to take it to one
of our Klever dealers, who can take care of the proper
disposal.
Caution!
• Charge the battery only with the proprietary battery charger.
• The battery can be recharged any time, even after short trips.
• Avoid temperatures below -10 ° C and above 45 ° C for a long
time.
• Never start with a cold battery.
• After an extended period (about two months) of storage, the
battery should be recharged.
• Protect the battery from humidity.
• Protect the battery from mechanical damage.
• Never open the battery yourself.
Used batteries do not belong in the household waste, they
must be disposed of properly.
.. Charging the battery
You can charge the battery on your bike (image 32) or o you
bike. For instance, indoors during the winter time (image 33).
Charging at any time, even after a partial discharge (e.g., after a
short distance of a few kilometres) is possible. There is no need
to wait until the battery is completely discharged, as it has no
memory eect. To remove the battery pack, refer to section
6.5.3.
For the technical data of the charger please read section 11
Technical data. To charge the battery, do the following:

and battery on a clean surface. Prevent contamination of
the charging sockets on the charger and the battery. Avoid
humidity and direct sunlight.
Please note! In case the charger is damaged, please
contact an authorised Klever dealer. Never open the
charger.
.. Range
The range specification of the system as indicated in image
34 can only be relative, as it is strongly dependent on the
chosen level of support, the technical condition of the bike
(oiled chain, proper tyre pressure, etc.), the total weight
of the system (bike, cyclist and luggage), the topography
of the chosen route and the weather (head- or tailwind,
winter or summer).
The lower the selected support level the larger the range
of the electric system. The below chart offers a proper
indication of the range you may expect under similar
conditions:
• Outside temperature between 12 - 30°C.
• Flat and slightly hilly terrain.
• Total system weight between 95 - 105 kg (cyclist’s weight
70 - 80 kg).
• Little to no wind.
Please note! In winter, the range can be up to 30% less
capacity due to lower temperatures.

Having removed the battery, please don’t forget to protect
the contact connector with the rubber seal. We advise to
always use the rubber seal (image 36).
Mounting the battery in the docking station
Insert the battery carefully. Make sure the groove of the
battery casing is carefully inserted into the guide rail of the
bicycle frame. Then slide the battery pack gently down until
you hear the lock engage and the electronic contacts are
connected (image 37). For this operation you do not need the
key of the lock. The lock will automatically snap in and the
battery is now locked, the system is ready for operation and
the battery protected from being stolen.
Caution! Do NOT ride your Y Muse 25 without battery!
Prior to starting the system, make sure to check whether
the electronics contacts of the battery are engaged and
locked in place. Riding your bike without the battery
could possibly damage the Klever BIACTRON-system.
.. Transport of the battery
The battery is subjected to the Dangerous Goods
Legislation. The user can transport the battery by road
and train without any further requirements. However,
when being transported by third parties (e.g., forwarders,
post or via air) special requirements on packing and
labelling of the battery pack must be observed.
For the preparation of the battery being transported,
consulting an expert for hazardous material is absolutely
required. Ship the battery only when the casing is
undamaged. Tape or mask off open contacts and pack up
the battery in such a manner that it cannot move around
in the packing. And please also observe detailed national
regulations.

torque when tightening the various bolts (see chapter 11
Technical data).
Caution! The seat post may never be installed over the
minimum insertion mark. Otherwise the post could
possibly break during riding, which could lead to injuries
(image 41).
Handlebar adjustment
The handlebar can be adjusted to your personal preferences, by
changing the angle of the handlebar stem and the height of the
handlebar (image 42).Your Klever dealer will be happy to set the
handlebar to your liking. However, in case you intend to adjust
the handlebar by yourself, then proceed as follows:
Loosen the big main M8 bolt of the stem with a 6 mm. Allen
key and adjust the angle of the stem and the position of the
handlebar (image 42).Tighten the M8 bolt with the proper
tightening torque.Also, please note that the change of the stem
angle has not only changed the position of the handlebar. It has
changed the position of the brake levers, the display and shifter
too!
You may want to correct the position of these components as
well. Loosen the 2 M5 bolts on the bottom side of the head of
the stem (image 43).And loosen the various bolts and screws
of display, brake levers and shifters with the proper keys. Adjust
the position of these components (image 44) and tighten the
bolts and screws. Make sure that while sitting on the E-bike
and putting your hands on the handlebar, your wrists are in a
relaxed position and not forced outward. Repeat the process if
necessary until you find the correct position of your hands and
wrists.
Caution! Please check whether the handlebar is correctly
tightened. You should not be able to twist the handlebar
while putting force on the grips.
Bicycle parts of the Y MuseBicycle parts of the Y Muse
. Bicycle parts of the Y Muse
All other components of your Y Muse 25 are high quality,
conventional bicycle components whose handling and operation
should be explained here briefly. Important information
regarding the adjustment, operation and maintenance of your
E-bike and its accessories are summarised here.You will also find
additional information in the accompanying user manuals of the
component suppliers
. Adjustment of saddle and
handlebar
The Y model comes in two frame sizes (M=Medium and
L=Large). The adjustment to your body size will be made with
the adjustment of the saddle, stem and handlebar. Your dealer
can do this on the spot. In order to readjust by yourself or in
the case of another cyclist, changing the settings is briefly
described below:
Caution! All work described requires mechanic experience
and appropriate tools. Use a torque wrench to tighten
the bolts and never exceed the maximum torque of the
bolts. All necessary tooling and information on the
recommended torque can be found in section 11 Technical
Data.
Adjustment of the saddle height
The optimal saddle height is if you touch the pedal with the
heel of your stretched leg, when sitting on the saddle (image
38). Or when you bring the ball of your foot to the centre of
the pedal, your knee should be slightly bent (image 39).
Loosen the seat clamp bolt with a 6 mm. Allen key (image 40)
and move the seat post with the saddle to its proper height.
Align the saddle with the frame using the saddle nose and the
bottom bracket or the frame tube as references. Fasten the
bolt of the seat clamp again and check the correct height of
the saddle. Repeat the process if necessary until you find the
correct saddle height.
The distance between saddle and handlebar (by pushing
the saddle forward or backward) and the saddle angle are
adjusted with the 2 saddle clamping bolts of the seat post
and a 5 mm. Allen key (image 40). Generally, the saddle
should be positioned horizontally.

. The suspension front fork
The Y Muse 25 is being equipped with a suspension front fork,
which improves the riding comfort. This front fork is pre-set
with factory settings. With a lockout button on the righthand
fork leg you can turn o the suspension (image 45). It is best
to use the lockout only on smooth and straight roads and
always use the suspension on badly paved roads.
For the long-term proper functioning of the front fork regular
maintenance is required. Some basic tips for maintenance:
clean the smooth surfaces of the stanchion tubes with a cloth
and a little water. After cleaning spray some water-repellent
oil on the stanchion tubes for lubrication of the bushings and
for a plush suspension function.
Caution! Never use a high-pressure cleaner or
aggressive detergent for the maintenance of the front
fork. Pay attention to the maintenance instructions in
the manual of the fork supplier.
. Disc brakes
Your Y Muse 25 is being equipped with high-quality hydraulic
disc brakes (image 46). These disc brake have very excellent
braking performances even under rainy weather and
other bad weather conditions. The disc brake has very low
maintenance and does not wear the rim. The brake consists
of a brake lever with a master cylinder, a brake hose, the
brake calliper and the disc rotor mounted on the hub.
While actuating the brake lever, the oil pressure is being
transmitted through the hose into the brake calliper. This
makes the brake pads contact the disc rotor.
Please note! New brake pads must be run-in in order
to achieve their best deceleration values. By braking at
least 30 times from approximately 30 km/h to complete
standstill the brake pads will achieve their maximum
brake power.
Not properly run-in brakes do not reach their best
deceleration values and are prone to vibrations and loud
squeal.
The brake pads and disc rotors must be regularly checked
for wear. If discs and brake pads are worn, they will need
to be replaced. In case the brake performance is getting
less and you are losing brake power or you can push the
brake lever through to the handlebar without any braking
Bicycle parts of the Y MuseBicycle parts of the Y Muse
eect, the brake system must be bled (purged). That and the
replacement of worn brake pads and disc rotors is better left
to authorised Klever dealers.
Caution! In case the brake performance is decreasing or the
system shows signs of leakage, do not continue to ride your
Y Muse and go and see your local Klever dealer immediately.
Please note! Oil or grease on the brake pads and disc
rotors will reduce the eect of the brake substantially.
Prevent in any case, while cleaning the bike and
lubricating the chain that oil or other liquids can
contaminate the brake pads and disc rotors.
Contaminated brake pads cannot be cleaned and need
to be replaced immediately. You can clean the disc with
brake cleaner or warm water and a little detergent if
necessary.
Please note! Ride more cautiously under humid and rainy
conditions because the stopping distance could be longer.
. Mechanical drive train and
gearshift
Your Y Muse 25 has a 10-speed derailleur drive train. Currently
a very ecient power transfer for your bike. These gears
will help to always use the optimal transmission (pedalling
& cadence) independent of terrain (flat or hilly area) and
independent of weather (tail- or headwind). You are able
to pedal always with an optimal cadence of 60-80 crank
revolutions per minute.
The complete drive train is composed of the bottom bracket,
the crank set, the rear derailleur, the chain, the gear shifter
and the 10-speed cassette (image 47). With the gear shifter
(image 48) you control the rear derailleur, which ensures that
the chain can move on the sprockets of the cassette.
Your dealer has checked your bike before the handover and
has adjusted the shifter. During the first miles however,
the shift cable could lengthen slightly and the shifter may
become misaligned and may have to be readjusted. With the
adjustment screw of the rear derailleur, you can readjust the
tension of the shift cable (image 47 & 48).
With the two positioning screws on the rear derailleur, you
can adjust the lower (H screw) and upper end stop
(L-screw), to make sure that the chain cannot get between
the smallest sprocket and the frame or between the largest
sprocket and the spokes of the rear wheel.
