Safety Instructions
12 13
The instructions and warnings in this manual refer exclusively
to the 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 muli, consult professional bicycle repair shop
and have these changes professionally checked.
Note that this manual cannot teach you how to ride cargo
bike like the muli. To learn how to ride the muli, proceed gent-
ly. Practice riding on calm and trac-free paths until you feel
condent and can keep the muli under control.
The company muli-cycles GmbH is not liable for errors or omissions in this docu-
ment. No liability or warranty is assumed if the muli is used beyond the intended
use. Warranty and liability are void in case of non-observance of the safety inst-
ructions, overloading, assembly errors, accidents, intentional misconduct, as well
as non-compliance with the specications for maintenance and care.
General safety instructions
The 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 muli and causing damage to the frame, basket and
fork. The information on maintenance and repair as well as the proper operation of
the muli in this manual are part of the intended use.
In case you use the muli for commercial purposes, keep in mind that you expose
the muli to increased loads. This increased load may shorten the maintenance in-
tervals specied in this manual.
Intended Use
Adhere to this usage recommendation for intended use, other-
wise you risk exceeding the load limits of the muli and causing
damage to the frame, basket and fork. In addition, use not in
accordance with the intended use will result in the loss of all
warranty claims.
Caution!
Indicates information that requires special attention.
Warning!
Warns you of misconduct that may result in minor perso-
nal injury and property damage.
Danger!
Indicates possible serious personal injury
up to death
Danger of burning!
The temperature is above 45° (coagulation of protein)
and can cause burns in humans.
Symbols used in this Manual
Even for commercial use, be sure to observe the load limits spe-
cied in this manual, on frames and components if applicable.
Also and in particular for commercial use, the checks mentio-
ned in the chapter „Before each trip“ must be performed before
each trip. This will ensure that you notice increased wear or pos-
sible damage due to intensive use in good time.
14 15
Keep in mind that cycling is fundamentally dangerous activity. Riding special bi-
cycle such as the muli also requires special training.
If necessary, use your bell to make yourself known in time. Ride with special fore-
sight.
We therefore recommend wearing helmet for the driver and also for the children
who may be transported in the cargo basket.
Safety instructions
We recommend wearing helmet both for the driver and for
the children who may be transported in the cargo basket.
Keep in mind that, like any other bicycle, the muli requi-
res regular maintenance and care in order to ensure long-
term suitability for riding. Check the brakes, tire pressure,
steering, rims and all parts subject to increased wear at
regular intervals. More information on this can be found
in the chapter „Care and maintenance intervals“ and the
chapters of the individual components in this manual,
among others.

Permissible total weight
The permissible total weight of the muli is 195kg. This permissible maximum weight
may be further restricted under certain circumstances by the component manu-
facturer‘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:
Examples of load distribution:
Example 1: 80kg driver + 25kg own weight muli
According to the maximum permissible total weight of 195kg, maximum of 87kg
may be loaded here. Of these 87kg, maximum of
maximum of 70kg may be loaded. The remaining 17kg may be partially or comple-
tely loaded onto the seat post (e.g. in the form of backpack) or onto the luggage
carrier.
Example 2: 100kg rider + 25kg own weight 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 cargo basket or
distributed between the cargo basket and the luggage carrier, whereby the luggage
carrier load may not exceed 18kg. On the seat post, however, no further load may
be applied here.
- Luggage carrier: Max 18kg
- Seatpost: Max 100kg + rider + backpack
- Load basket: Max 70kg
Max 18kg
Max 100kg
Max 70kg
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.
Trailer
The muli is not approved for the use of trailers.
18 19
Vibration loads
When using cargo bike such as the muli, vibration loads can occur on the rider‘s
body. When riding cargo bike, vibrations can be transmitted 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 relationships:
- The higher the speed, the higher the magnitude of the vibrations.
- The lighter the rider, the higher the vibration load.
- The highest vibration levels are reached when the vehicle is unladen.
- The load of the whole-body vibrations is stronger than that of the hand-arm
vibrations. In the case of whole-body vibrations, the limit values are reached in
shorter time.
- The lower the tire pressure, the lower the vibration load.
Exposure to whole-body vibration can be prevented with saddle suspension.
This component can be selected when ordering or retrotted independently after
purchase.
Note that the muli is not approved for the mounting of
child seats on the seat tube or even the seat post. The attach-
ment of such child seats can lead to deformation of the frame.
The permissible total weight of the muli is 195kg. This means 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 circumstances. By over-
loading, you risk damaging and breaking the muli. This can result in
serious falls and accidents.
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 recommendation for
use and imitation. Riding on the rear wheel does not represent
intended use.

Legal requirements
To use the muli on public roads, you must comply with the applicable legal require-
ments of the country in which you intend to travel. Inform yourself about the corre-
sponding country-specic laws.
In Germany, three points are required according to the Road Trac Licensing Regu-
lations (StVZO):
1. The bike 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 reflector at the front
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.
In each country where you will be riding your muli on public
roads, nd out about any nationally applicable legal require-
ments for riding bicycle.
The German StVZO is continuously revised and updated. Inform yourself regularly
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 require-
ments for road vehicles in articles 213 to 218.

Assembly instruction
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.
Assembly of 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.
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.
OutriggerPrepared screw
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. Since
this is self-locking nut, you can adjust
the heavy or light steering movement
vi the contact pressure of the screw.
Adjust the screw pressure so that the
handlebar can be turned comfortably.
A very high contact pressure increases
wear, very low pressure can cause
the steering linkage to rattle.
Check this screw connection at regu-
lar intervals!
3. Then carry out all the instructions given in chapters 4 and 5 („Before the rst
ride“ and „Before each ride“).

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
Mounting the pedals
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.

After all the adjustments described below, perform
functional test of the bike. Follow the instructions in the
„Before each ride“ section. After the adjustments have
been made, test ride your muli in place free of trac.
Adapting the muli to the rider
The muli is only available in one
frame size. The top tube sits so low
that very comfortable entry is
possible and the standover height
usually provides enough freedom of
movement 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 be-
yond the „MIN/MAX“ mark.
Make sure that the seat
post is not too deep
in the seat tube. With
some seat posts, the
tube tapers at the upper
end and can no longer
be clamped securely
there.
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 muli has height-adjustable stem adapter,
through which the handlebar height can be ad-
justed in height by up to 10cm with few simple
steps. Open the quick release lever on the hand-
lebar 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 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 muli.
Adapting the muli to the rider
34 35
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 muli to the rider
36 37
Before the rst ride
Please be sure to read this information carefully before driving your muli for the
rst time.
The muli is special bicycle with very specic riding characteristics. Even if you have
already ridden other bicycles or even cargo bikes with similar design, try riding the
muli carefully in trac-free, calm place and 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 muli and thus increases the risk of falling.
Carry out your rst driving tests in place free of trac on
paved, clean, dry paths that are not covered with debris
or sand.
The weight and weight distribution of the muli diers sig-
nicantly from the weight and weight distribution of other
conventional bicycles. Be aware that this makes it more
dicult to park, push, lift and carry the muli in everyday
handling.
The muli is only available in one frame size. So that you can optimally adjust the 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 correspond 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 driver
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 riding without tight turns.
Ride O
38 39
Since the steering movement on the muli is not transmitted directly from the handle-
bar to the wheel, but vi the steering linkage underneath the load 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 steering 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 charac-
teristics carefully in place free of trac.
Steering response
Familiarize yourself with the brake system of the muli before your rst ride. The
left brake lever operates the front brake, the right brake lever the rear brake. If you
are not used to this brake lever arrangement or have previously ridden bikes with
back pedalling 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 muli is equipped with very high-quality disc brakes on the front and rear wheel,
which achieve very high braking eect. Therefore, rehearse the braking with the
muli in detail before you use it in public trac.
Brake system
Particular care should be taken when using the front wheel
brake, as braking too hard, especially when cornering and
even with slight steering angle, can cause the wheel to
slip and lead to fall. It is best to always use the front bra-
ke in combination with the rear brake.
When transporting children in the load basket in particular, en-
sure 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.
Keep in mind that the braking eect and the grip of the tires on
the ground can be greatly reduced by wet conditions. Therefo-
re, drive slower than usual in the rain and on wet surfaces 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. Unintentional and
incorrect application of the brakes can lead to serious falls and
accidents.
For more information on brakes, see the „Brake system“ section.
