Safety instructions
12 13
The instructions and warnings in this manual refer exclusively
to the e-muli and are not transferable to other bicycles. This
manual does not impart the skills of professional bicycle
mechanic. If you want to make changes to the basic equip-
ment of the e-muli, consult professional bicycle repair shop
and have these changes professionally checked.
Note that this manual cannot teach you how to ride pede-
lec like the e-muli. To learn how to ride the e-muli, proceed
carefully, practice riding on quiet and trac-free paths until
you feel condent and can keep the e-muli under control.
Before using your e-muli, read the enclosed Shimano manu-
al completely. Be sure to follow all safety instructions in the
Shimano manual.
The company muli-cycles GmbH is not liable for errors or omissions in this do-
cument. No liability or warranty is assumed if the e-muli is used beyond the
intended use. Warranty and liability are void in case of non-observance of the
safety instructions, overloading, assembly errors, accidents, intentional miscon-
duct, tampering with the electrical system, non-compliance with the specica-
tions for maintenance and care.
The e-muli is primarily bicycle for urban areas. It is therefore designed for use
on paved bike paths where the tires remain in constant contact with the ground.
It is not suitable for rough terrain, high-speed descents, jumps, or riding with
extreme lateral positions.
Please adhere to this usage recommendation, otherwise you risk exceeding the
load limits of the e-muli and causing damage to the frame, basket and fork.
The information on maintenance and servicing as well as the proper operation of
the e-muli in these instructions are part of the intended use.
Symbols used in this Manual
Also, and especially in the case of commercial use, the checks
listed in the chapter „Before each trip“ must be carried out
before each trip. This will ensure that you notice increased
wear or possible damage due to intensive use in good time.
Even in the case of commercial use, it is essential to obser-
ve the load limits specied in this manual and, if applicable,
on the frame and components must be observed.
Before performing any work on your e-muli such as mainte-
nance, repair, assembly or transporting it, switch o the drive
system and remove the battery. There is risk of injury if the
drive system is activated unintentionally.

The e-muli st and e-muli px are bicycles in the category of Pedelecs (Pedal
Electric Cycles) or EPACs (Electrically Power Assisted Cycles). On pedelec, the
auxiliary motor turns on only when the rider pedals. When they stop pedaling,
the motor also stops assisting.
The e-mulis st and px have an electric drive that provides assistance when riding
up to speed of 25km/h. The assistance automatically stops again when you
reach speed of 25km/h. Both models can be ridden like normal bicycle even
with the drive system turned o.
Keep in mind that you move faster and quieter with an e-muli than with bicy-
cle without electronic assistance. You can therefore easily surprise other road
users. If necessary, use your bell to make yourself known in time. Ride with extr
foresight.
Keep in mind that cycling in general - and especially riding pedelec - is dan-
gerous activity.
We therefore recommend wearing helmet for the rider as well as for the chil-
dren who may be transported in the cargo basket.
Safety instructions
Keep in mind that, like any other bicycle, the e-muli requires
regular maintenance and care in order to ensure long-term
suitability for riding. Check brakes, tire pressure, steering,
rims and all parts that are subject to increased wear at regular
intervals. More information on this can be found in the chap-
ter „Care and maintenance intervals“ and the chapters of the
individual components in this manual.
We recommend wearing helmet both for the driver
and for the children who may be transported in the car-
go basket.
When climbing on, note that the e-muli starts moving
immediately when you step on the pedal with the assis-
tance level switched on. To climb onto the e-muli safely,
apply one of the two brakes when climbing on. The im-
mediate thrust of the drive can otherwise easily lead to
accidents.
The EPAC, like all mechanical components, is subject to wear
and high stress. Dierent materials and components can re-
act dierently to wear or continuous stress. If component
exceeds its intended service life, it can suddenly fail, possibly
causing harm to the driver. Any type of cracking, scoring or
color change in highly stressed areas indicates the expiration
of the component‘s service life; the component should then
be replaced.
Adhere to this usage recommendation for intended use, ot-
herwise you risk exceeding the load limits of the e-muli and
causing damage to the frame, basket and fork. In addition,
improper use will result in the loss of all warranty claims.

Examples of load distribution:
Example 1: 80kg driver + 33kg tare weight e-muli
According to the maximum permissible total weight of 195kg, maximum of 82kg
may be loaded here. Of these 82kg may be loaded into the load basket
maximum of 70kg may be loaded. The remaining 12kg may be partially or com-
pletely loaded onto the seat post (e.g. in the form of backpack) or onto the
luggage carrier.
Example 2: 100kg rider + 33kg own weight e-muli
According to the maximum permissible total weight of 195kg, maximum of 62kg
may be loaded here. These 62kg may be loaded completely in the load basket or
distributed between the load basket and the luggage carrier, whereby the lugga-
ge carrier load may not exceed 18kg. On the seat post, however, no further load
may be applied here.
Note that the e-muli is not approved for the mounting of
child seats on the seat tube or even the seat post. The
attachment of such child seats can lead to deformation of
the frame.
Frame number/serial number
The frame number is stamped into the
frame and is located at the marked posi-
tion in the picture.
Permissible total weight
The permissible total weight of the e-muli is 195kg. This permissible maximum
weight may be further restricted under certain circumstances by the component
manufacturer‘s recommendation for use.
The permissible total weight is composed of:
Dead weight of the muli 25kg
+ weight of the driver
+ weight of the payload
Permissible maximum load limits of the various
load suspension points:
- Luggage carrier: Max 18kg
- Seatpost: Max 100kg + rider + backpack
- Cargo basket: Max 70kg
Max 18kg
Max 100kg
Max 70kg
Trailer
The muli is not approved for the use of trailers.
Note on the suspension seatpost:
The suspension seatpost in our program is equipped with spring for
maximum rider weight of 85kg. For higher rider weight you must resort to
non-suspended seatpost or retrot spring with higher permissible total weight.
18 19
The short scenes from our crowdfunding video from spring
2017, in which the muli is moved on the rear wheel (so-called
wheelie), are advertising images and do not present recom-
mendation for use and imitation. Riding on the rear wheel does
not represent intended use.
The permissible total weight of the e-muli is 195kg. This me-
ans that the weight of the bike, the rider and the load must
not exceed 195kg. A maximum of 100kg may be applied to the
seat tube, and maximum of 70kg may be applied to the load
basket. These load limits must not be exceeded under any cir-
cumstances. By overloading, you risk damaging and breaking
the e-muli. This can result in serious falls and accidents.
Never open the electric actuator yourself. By opening the ac-
tuator, you risk damaging it permanently. Repairs to all parts
of the electric actuator may only be carried out by qualied
persons and only with original spare parts. Unauthorized ope-
ning of the electric actuator will void the warranty and gua-
rantee.
Never immerse the battery in water or clean it with water jet.
There is risk of short circuit, which can cause re hazard.
Do not place the battery on wet contacts of the battery hol-
der.
When using cargo pedelec such as the e-muli st or e-muli px, the rider‘s body may
be exposed to vibrations. When riding cargo pedelec, vibrations can be transmit-
ted in particular vi the buttocks to the back and passed on to the entire body.
The decisive factor for the extent of the vibrations is the road surface on which the
rider is riding. Accordingly, riding over cobblestones is more stressful than riding on
paved roads.
Consider the following correlations:
- The higher the speed, the higher the level of vibration.
- The lighter the rider, the higher the vibration load.
- The highest vibration levels are reached in the unloaded state.
- The load of the whole-body vibrations is stronger than that of the hand-arm vib-
ration. In the case of whole-body vibration, the limit values are reached in shorter
time.
- The lower the tire pressure, the lower the vibration load.
Exposure to whole-body vibrations can be prevented with saddle suspension
system, which is standard on the muli st. Such saddle suspension is also recom-
mended on the muli px. This option can be selected when ordering or retrotted
independently after purchase.

To use the e-muli on public roads, you must comply with the applicable legal
requirements of the country in which you intend to travel. Inform yourself about
the corresponding country-specic laws.
In Germany, the Road Trac Licensing Regulations (StVZO) stipulate three
points:
1. The bicycle must have two independently functioning brakes.
2. The bicycle must have the following lighting devices:
I. White front and red rear lights that cannot be turned on
together.
II. One white front reflector
III. One red Z-reflector at the rear
IV. Side reflectors on the wheel, either in the form of reflective
rings around the entire circumference of the wheel or two
spoke reflectors per wheel.
V. Two yellow reflectors per pedal, facing front and rear.
3. The bicycle must have bright sounding bell.
Inform yourself in each country in which you are driving your e-muli on
public roads about possible nationally applicable legal regulations for
driving with an EPAC.
The German StVZO is continuously revised and updated. Inform yourself regu-
larly about the current status of the legal situation in Germany.
For participation in public road trac in Austria, you must comply with the 146th
Regulation / Bicycle Regulation. You can nd this in the Federal Law Gazette
Austria.
In Switzerland, the valid regulations are in the ordinances on the technical requi-
rements for road vehicles in articles 213 to 218.

Open the cardboard box on the side of the front wheel, remove the wheel triang-
le and carefully pull the e-muli out of the box. Hold the e-muli in the scales while
pulling it out and make sure that it does not tip over. To assemble the e-muli, rst
unfold the double-leg stand. This ensures that the e-muli stands securely.
Mounting the steering linkage
The e-muli is completely pre-assembled and adjusted except for few parts.
You only need to carefully fasten one screw - the connection of the steering arm
to the steering linkage. It is important that you plug the individual elements onto
each other in the correct order. The screw is attached to the steering linkage and
prepared accordingly.
1. Guide the steering tube extension and the swivel bearing head of the steering
linkage over each other and put the individual parts on top of each other. To do
this, simply loosen the nut at the bottom, remove the nut and washer. Then put
the bolt through the extension arm and
put the washer and nut back on the bolt. The slide bearing for the boom is then
pressed into the boom by tightening the screw.
by tightening the screw.
2. When you have prepared the con-
nection accordingly, tighten the screw
with 6 mm Allen key and 13 mm
open-end wrench. This presses the
plain bearing into the cantilever. Sin-
ce this is self-locking nut, you can
adjust the heavy or light steering mo-
vement vi the contact pressure of
the screw. Adjust the screw pressure
so that the handlebar can be turned
comfortably. A very high contact pres-
sure increases wear, very low pres-
sure can cause the steering linkage to
rattle. Check this screw connection at
regular intervals!
3. Then carry out all the instructions given in chapters 4 and 5 („Before the rst
ride“ and „Before each ride“).
Attention! The steering linkage is highly safety-relevant
component. Fasten this screw connection with the greatest
care and ensure that the connection is rmly seated.

On the axles of the pedals there is small marking for the side assignment. „R“
stands for right, „L“ for left. Note that the left pedal has left-hand thread and
must be screwed counterclockwise into the crank.
Grease the pedal thread with commercially available assembly grease and screw
it into the corresponding crank arm by hand. Make absolutely sure that you do

Check the tightness of the pedals after 100km of driving.
Make absolutely sure that you do not tilt the pedal when screwing
it in. A pedal that is screwed in at an angle can cause massive
damage to the thread.
not tilt the pedal when screwing it
in. A pedal that is screwed in at an
angle can cause massive damage to
the thread. Then tighten the pedals
with 15 mm open-end wrench if the
pedal has external hex nuts, or with
6 mm Allen wrench if your pedal
has an internal hex bolt. The corre-
sponding torques can also be found
listed in the „Recommended screw
torques“ section.
Mount the included bell at the desired position on the handlebar. Mount the bell
so that you can reach it very quickly with your thumb without having to take your
hand o the handle.
Mounting the bell
Before you take your e-muli for the rst ride after the assem-
bly has been completed, be sure to read the chapter „Before
the rst ride“ carefully and implement all instructions contai-
ned therein.
Pull the muli out of the box extremely carefully to prevent
scratches from occurring.
Check the bolts and nuts on the steering linkage before
each ride. Loosening these connections while driving can
lead to serious falls and life-threatening injuries.
Assembly instruction
28 29
After all the adjustments described below, perform
functional test of the wheel. Follow the instructions in the
„Before each ride“ section. After the adjustments have
been made, test ride your e-muli in place free of trac.
The e-muli is only available in one
frame size. The top tube sits so low
that very comfortable entry is pos-
sible and the standover height usually
provides enough freedom of move-
ment for all adult riders.
Adjusting the seat height
You can nd out the optimum seat
height as follows: sit on the saddle
and place one leg with the heel on
the pedal. The pedal should be in the
lowest position for this. The saddle
should be adjusted so that the leg is
fully extended in this position.
Vi the quick release on the saddle clamp, the saddle
can be very easily adjusted in height. Open the quick
release and set the desired seat height.
Make sure that you do not pull the seat post out of the
seat tube beyond the „MIN/MAX“ mark.
Make sure that the seat
post is not too deep in
the seat tube. With some
seat posts, the tube ta-
pers at the upper end
and can no longer be
clamped securely there.
Adapting the e-muli to the rider
30 31
Then tighten the preload nut until counterpressure is felt at the quick-release lever
from the middle of the entire lever travel and the force of the ball of the hand is
required at the end of the lever travel to close the lever completely. It must not
be possible to twist or tilt the saddle when the saddle clamp is closed. Align the
saddle so that it is in line with the top tube.
The foot is optimally positioned on the pedal when
the ball of the foot is above the pedal axle.
Make sure that you can still reach the ground with
the tips of your feet when sitting on the saddle.
The maximum load on the saddle is 100kg. This includes
backpack and other weights on the rider‘s body.
Consider all weights that you load in addition to their own
weight on the seat tube. The load limit of 100kg must not
be exceeded!
The quick-release must be rmly closed and t tightly
against the seat post before you start riding. The tip of the
lever must point forward when closed ( see also illustration
on page 29 below).
Adjusting the handlebar height
The e-muli has height-adjustable stem adapter,
through which the handlebar height can be adjusted in
height by up to 10cm with few simple steps.
Open the quick release lever on the handlebar stem
and pull the handlebars up as far as you need and then
close the quick release again.
Make sure you never adjust the stem adapter so that it is pulled
past the min/max mark and the quick release lever is rmly closed.
Adapting the e-muli to the rider
32 33
Adjusting the seat length and saddle angle
The distance between the saddle and
handlebar grips can be adjusted somew-
hat by moving the seat post slide. It should
be noted that moving the saddle changes
the pedaling angle on the pedals.
By loosening the screw on the seat post
carriage, you can also adjust the seat
angle of the saddle.
To adjust the seat length and the saddle
angle, you must loosen the hexagon so-
cket screw on the saddle support carria-
ge with an appropriate wrench and 2-3
turns. Be careful not to unscrew the screw
completely. Then set the desired position
and angle of the saddle and tighten the
screw again. Make sure that the saddle
again in horizontal line determine.
After adjustment, make sure that the
saddle cannot be twisted or tilted by
pulling and pushing on the front and
back of the saddle with your hands.
Under no circumstances should the saddle be xed in
tilted back position.
Turning gear and brake levers
You can adjust the shift and brake
levers on the handlebars to suit your
seating and hand position. To do this,
loosen the Allen screw on the shift
and brake levers and turn them to
the desired position and tighten the
screws again.
In the riding position, test whether
you can easily reach the shift and
brake levers with your ngers. Also
make sure that the forearm and bra-
ke lever form line in the riding posi-
tion.
After completing the adjustment,
make sure that the shift and brake
levers cannot be twisted.
No bar ends may be installed on the e-muli.

Adjusting the brake lever grip
width
The distance between the handlebar
grip and brake lever can be adjusted. To
reduce the grip width, turn the hexagon
socket screw on the brake lever coun-
terclockwise. To increase the grip width,
turn the screw clockwise.
Note that adjusting the grip width may
require an adjustment of the brake pad
spacing. For more information, see the
„Brake system“ section.
It must not be possible to pull the brake lever through to
the handlebar. The brake must engage clearly before this.
Observe the torque specications for handlebar, stem and
stem adapter
Setting the lights
The rear light is xed to rigid bracket and does not need to be adjusted. The
front light, on the other hand, can still be tilted up and down on its bracket. Ad-
just the light so that the light cone hits the ground in the range 5-8 meters in front
of the front wheel.
Make sure that the lamp is never tilted so that it shines
upwards. This could blind oncoming road users. Falls and
serious accidents can be the result.
Adapting the e-muli to the rider
36 37
Please be sure to read this information carefully before driving your e-muli for
the rst time!
The muli is special bicycle with very specic riding characteristics. Even if
you have already ridden other bicycles or cargo bikes with similar design, try
riding the e-muli st or px carefully in trac-free, quiet place on paved paths.
Do not start your rst riding attempts on surface covered with sticks, sand,
stones or other debris, which makes it dicult for you to control the e-muli
and thus increases the risk of falling.
Carry out their rst driving tests in place free of traf-
c on paved, clean, dry paths not covered with debris
or sand.
The weight and weight distribution of the muli st and
muli px dier signicantly from the weight and weight
distribution of the muli muskel or other conventional
bikes without electric drive. A pedelec is signicantly
heavier than bicycle without drive. Be aware that this
makes it more dicult to park, push, lift and carry the
e-muli in everyday handling.
The e-muli is only available in one frame size. So that you can optimally adjust
the e-muli to your respective body size, both the seat post and the handlebar
stem are height-adjustable. Adjust the saddle and handlebars so that they cor-
respond to your body size. The correct saddle height is achieved when you can
still reach the pedal with your heel in the lowest pedal position. Check whether
you can still reach the ground with the tips of your feet at this saddle height. For
more information on this topic, see the section „Adjusting the muli to the rider“.
Adapt to the rider
Step over the top tube with one leg and place your foot on the ground. Do not
step directly on the pedals so that the motor assistance does not start uninten-
tionally and you lose control of the e-muli.
The electric pedal assistance makes it easier for you to start o. The safest way
to start o is not to look at the basket or the front wheel, but to look at the road
little further away and start o with strong pedal. Slow, hesitant starts make it
more dicult to maintain your balance. Take your rst ride on track that allows
for good straight-line driving without tight turns.
Ride-Off
When getting on your e-muli, be careful not to pedal direct-
ly so that the motor assistance does not start unexpectedly
and you possibly fall. First sit on the saddle and take rm
grip on the handlebars - now you can start pedaling.
Before the rst ride
38 39
Since the steering movement of the muli is not transmitted directly from the
handlebar to the wheel, but vi the steering linkage underneath the cargo basket
to the front wheel, the driving behavior of the muli is very special. Familiarize
yourself with the steering mechanism before your rst ride by testing the steer-
ing while stationary. Usually you can hardly see the front wheel while driving
(depending on whether the basket is open or closed); you will have to get used
to this. Test the steering characteristics carefully in place free of trac.
Steering response
Familiarize yourself with the brake system of the e-muli before your rst ride.
The left brake lever operates the front wheel brake, the right brake lever the rear
wheel brake. If you are not used to this brake lever arrangement or have previ-
ously ridden bikes with coaster brakes, it is essential that you carefully get used
to this arrangement. Unintentional and incorrect application of the brakes can
lead to serious falls and accidents.
The e-muli is equipped with very high-quality disc brakes on the front and rear
wheel, which achieve very high braking eect. Therefore, rehearse braking with
the e-muli in detail before you ride it in public trac.
Brake system
Particular care should be taken when using the front
wheel brake, as braking too hard, especially when cor-
nering and even with slight steering angle, can cause
the wheel to slip and lead to fall. It is best to always
use the front brake in combination with the rear brake.
When transporting children in the cargo basket in particular,
ensure that you brake gently and do not apply the brakes in
jerky manner. Jerky braking takes children by surprise and
can lead to bruises and injuries, especially in the head and
neck area.
Please note that the brakes of your e-muli are always stron-
ger than the drive. Thus, you always have the possibility to
bring your e-muli to stop, even if the drive should uninten-
tionally support you too strongly.
Keep in mind that the braking eect and the grip of the ti-
res on the ground can be greatly reduced by wet conditions.
Therefore, drive slower than usual in the rain and on wet sur-
faces and be especially careful.
If you are not used to the brake lever assignment of the muli
or have previously ridden bikes with coaster, it is essential
that you carefully get used to this arrangement. Uninten-
tional and incorrect application of the brakes can lead to
serious falls and accidents.
For more information on brakes, see the „Brake system“ section.
