A word about this
safety manual
DEAR KUBERG CUSTOMER
Congratulations on your purchase of a KUBERG Ranger. You now own a state of the
art electric motorcycle that will give you endless thrills if you maintain it properly. We
welcome you to the community of KUBERG riders.
Your KUBERG Ranger is a performance motorcycle that should be treated with caution
and used in safe environments. The Ranger is highly adjustable and can be set up
specifically for the rider. Please do not allow the motorcycle to be used or adjusted by
other operators.
Your KUBERG Ranger is driven by a powerful electric motor, which requires experience
and careful handling. The speed and torque settings MUST be set to suit the abilities
of the rider. Please remember that even when the torque setting is set to a slow setting,
the torque on these motors is virtually instant. This means that opening the throttle
will propel the motorcycle to a rapid speed almost instantly. For developing good riding
skills this is a wonderful feature, as it will teach riders throttle control gradually with lower
power. If the maximum power and torque is set too aggressively, the rider may accelerate
to a speed he/she is not comfortable with. Your Ranger has great capabilities, and can
grow with the skills of the rider to very high levels of performance, but it is important to
start slow and speed up as you improve.
KUBERG motorcycles (except the KUBERG Freerider Street) are designed for o road use
only and must not be used on public roads or sidewalks. Please check and obey all local
and state laws. KUBERG motorcycles should only be ridden in safe areas where all laws
are being followed and all required permissions are given.
KUBERG motorcycles are amazingly capable, and can be used from the earliest stages
of learning to ride all the way through to veteran riders. The secret of learning to ride
well is to be able to ride a lot, and KUBERG motorcycles make this learning process very
gratifying for teenagers and adults alike. Thanks again for purchasing a KUBERG
motorcycle, and we hope you enjoy the ride!

Safety advice
WARNING!
Failure to obey all of the warnings & instructions contained in this manual may result in
serious injury or death and/or permanent damage to your KUBERG motorcycle.
Speed & torque settings
Your KUBERG Ranger features a power and torque control button that must be set for
the abilities of the rider. This must be set by the responsible supervising adult before
each and every ride. Instructing and practicing in a controlled situation will allow the rider
to learn how to operate the motorcycle safely. Go to page 16 to find detailed instructions
how to set up the dierent torque modes.
WARNING! ADULT SUPERVISION REQUIRED
This vehicle must be used in the presence of adult supervision to insure that safe riding
practices are established and followed. Even though teenagers are of the recommended
age to use this vehicle, not all teenagers have the strength, skills or judgment needed
to operate this vehicle safely. Parents should permit continued use of this vehicle only if
they determine that their child or teenager has the ability and judgment to operate the
vehicle safely.
WARNING! OFFROAD USE ONLY
KUBERG motorcycles are designed primarily for OFF-ROAD use. Please check your local,
state and national regulations as to whether single–track, motorized electric vehicles are
legal for road use in your area. KUBERG Ranger is not homologated for road use in the
European Union.
WARNING!
This motorcycle is for personal use only and is not intended for commercial purposes.
The use of this motorcycle for commercial purposes, such as rentals, will void all
warranties.
Electric drivetrain
The fully electric drivetrain of this motorcycle is dierent from any gasoline motorcycle,
in that:
1There is very little engine braking and no engine noise.
2When going into corners or coming to a stop the rider will be fully dependent
on the motorcycle brakes.
3This motorcycle has a regen braking function, controlled by the button located on
the handlebar. (or by the throttle negative movement, depending on motorcycle
revision) When you push this button during riding (or turn the throttle to negative
direction), the motorcycle will start to decelerate significantly.
7

4Passers-by may not hear you approach – so extra caution should be taken.
5Make yourself conspicuous in order to reduce the chance of other vehicle users
or pedestrians being unaware of you approaching.
6Be aware that your motorcycle is still ON when stopped and while at an “idle”.
WARNING!
Accidental twisting the throttle can cause serious harm.
Safe riding practices
1SINGLE OPERATOR ONLY! No passengers!
2Long hair, loose clothing or items worn by the rider must be covered to prevent
entanglement in moving parts of the vehicle or the surroundings whilst riding
3Do not exceed the weight limit. Heavier riders may significantly reduce performance
and/or render the vehicle unstable and/or over-tax the brakes and other control
devices. Heavier riders may cause structural damage not covered by the warranty.
4Do not touch any moving or hot parts.
5DO NOT RIDE AT NIGHT OR UNDER LOW VISIBILITY CONDITIONS, if your KUBERG
Ranger is not equipped with the light kit (sold separately).
6Do not immerse this vehicle in water.
7Do not combine regen braking with regular brakes.
8BEFORE TOWING A TRAILER, GO TO PAGE 34 TO READ THE INSTRUCTIONS FIRST!
9Do not ride on steep or uneven surfaces. Steep or uneven surfaces greatly increase
the likelihood of loss-of-control.
10 Do not ride faster than the conditions permit for safe operation. Excess speed
greatly increases the likelihood of loss-of-control.
11 The rider should be securely seated on the vehicle or to have one leg on foot rail (no
seat version) ready to ride before turning the power switch on.
Ride where other motorists, pedestrians and cyclists can see you. Avoid riding in another
motorist’s blind spot. Know your skills and limits. Stay within your limits in order to avoid
an accident.
NOTE:
Many motorcycle accidents are caused by rider error. A typical error made by motorcycle
riders is veering wide on a turn due to EXCESSIVE SPEED or under cornering due to
insucient lean angle for the given speed.
WARNING!
Maintain a proper posture while riding. The posture of the rider is important for proper
control of the motorcycle. The rider should keep both hands on the handlebars and
both feet on the footrail during operation in order to maintain control of the motorcycle.
Never ride under the influence of alcohol or other drugs. Go to page 31 to find detailed
instructions concerning proper riding technique.

13

Break-in period
To assure future reliability and top-notch performance of your KUBERG Ranger, please pay
an extra attention during your first 150 km/93 miles or three full-charge cycles (whichever
comes first). During this period please obey the following:
Avoid full-throttle starts and accelerate gradually.
Avoid full speed riding and use the Beginner and the Sport mode only. Do not use the
Race mode.
Avoid hard braking. New brakes need some time to break in with moderate use.
Motorcycle controls
Magnetic Kill Switch (ON/OFF switch)
The magnetic kill switch is located on the left hand side of the handlebars. Always switch
the motorcycle into the OFF position when stopped or parked.
WARNING!
If the power is turned on and the throttle is open, the motorcycle will accelerate
immediately. This is potentially very dangerous. The rider’s right hand should be used to
switch the power on, with no hands on the throttle.
Regen braking
This motorcycle has a regen braking
function, controlled by the button located
on the handlebar (or by the throttle negative
movement, depending on motorcycle revision).
When you push this button during riding (or
turn the throttle to negative direction), the
motorcycle will start to decelerate significantly.
WARNING!
Do not combine regen braking with regular brakes, as it can easily block your rear wheel
and may result in injury or death and/or damage to your motorcycle.
14 Ranger - OWNER‘S MANUAL

percentage status and voltage.
Setting up your Kuberg
Ranger for riding
WARNING!
Improper set-up is dangerous! It is your responsibility to set the motorcycle to the
ability of the rider. Failure to do so, may result in injury or death, and/or damage to your
motorcycle.
NOTE:
A responsible adult must ensure that the KUBERG Ranger and its rider are prepared for
every ride. The motorcycle must be set to the abilities of the rider, and the rider and the
motorcycle must be supervised when ridden by a child or a teenager. Novice riders can lose
concentration quickly, and be easily distracted. If the power is set too high, an accident
could occur. RIDE SAFE!

Drivetrain
Your KUBERG Ranger features two traditional chains and sprockets and the central
double sprocket. It has a direct drive with no clutch and one reduction gear. Both chains
need to be lubricated and adjusted on a regular basis and before every ride. There
should be only a very little slack in the chain.
Adjusting chain tensions
Follow these steps to adjust the chain tension:
1Make sure the on/o switch is in the OFF position.
2Lift the motorcycle onto a block or stand so that both wheels are o the ground.
3Using the Allen wrench #10 and the open wrench #24 loosen the rear axle nut.
4Using the Allen wrench #4 (or Torx wrench #30) loosen and remove 3 bolts holding the
primary chain guard. Each bolt has its own spacer under the chain guard.
16 Ranger - OWNER‘S MANUAL
Setting power & torque modes
Follow these steps to limit the maximum power and torque on your KUBERG Ranger:
1Turn o your motorcycle.
2Press and hold the control button. The control
button is located on the right side of the
handlebar.
3Turn on your motorcycle.
4The motorcycle will beep one, two or three times
to indicate the desired power mode
One beep indicates Beginner Mode (low-
power), two beeps indicate Sport Mode
(medium-power) and three beeps indicate
Race Mode (maximum-power).
For example, if you want the medium power
mode, hold the control button for two beeps and release. The motorcycle will
confirm your selection with an audible “one”, “two” or “three” beep sound.
5The power mode is now set. If you want to set a dierent power mode level, repeat
the process from step 1.
CAUTION!
Sport and Race modes should only be used by experienced riders!

17
5Remove the chain guard and uncover the primary
chain.
6Using the Allen wrench #4 (or Torx wrench #30)
loosen 3 bolts holding the motor in the frame just
enought for the motor to be able to move up and
down.
7Using a dry cloth and a motorcycle chain cleaner
remove all the dirt from both chains.
8By moving the motor up or down adjust the primary
chain tension. Do not tighten the chain too much
that there is no slack at all. It should be ‘taught’, not
‘tight’.
9Move the motor to the desired position and tighten 3 motor bolts to secure its
position in frame (9,5 - 10,5 Nm).
10 Install primary chain guard using remaining 3 bolts and 3 spacers (9,5 - 10,5 Nm).
11 DOUBLE CHECK THAT ALL MOTOR AND CHAIN GUARD BOLTS ARE TIGHTEN
PROPERLY!
12 Using the open wrench #10 turn the adjustment nuts on the rear wheel evenly on
both sides. Be precise - very small movements make a big dierence. Again, do
not tighten the secondary chain too much that there is no slack at all. It should be
‘taught’, not ‘tight’ and the rear wheel and sprocket need to be in alignment with the
secondary chain.
13 Tighten the rear axle nut (78 - 80 Nm), check the rear sprocket for tightness and
ensure all bolts are tight.
14 While turning the rear wheel by hand, lubricate both chains with the oroad
motorcycle chain lube spray.
15 Spin the rear wheel by hand at least 10 times more around and wait a few minutes for
a spray to dry.
16 Remove the excess lubricant using a cloth. If the wheel does not spin freely, go to
page 23 and follow the brake adjustment instructions.
17 Check once more the rear wheel for alignment, and both chains for tension.
WARNING!
Failure to maintain and adjust the chain and align the wheel correctly could result in
the primary and/or secondary chain jumping o the sprockets, causing a potentially
dangerous and damaging situation.
Motor performance
The KUBERG Ranger has multiple sensors and control software to prevent the batteries,
the motor and the controller from overheating. Once the temperature of batteries, motor
or controller reaches a high temperature, the motorcycle power will be limited to 70%

until the components are able to cool down. If the motorcycle continues to overheat,
the controller will shut o the motorcycle until the components have cooled. This takes
approximately 15 to 30 minutes.
Thermal shutdown of the motor can occur when riding in situations that stress the motor
for a long periods of time, such as long up-hills or continuous full throttle operation with no
rest period for the motor or a dirt on the motor cooling ribs. For the best riding experience
keep your motorcycle clean.
Weather eects on performance
Very cold weather (-10°C / 14°F and lower) is hard on the motorcycle’s batteries and, as
a result, the battery charge will not last as long as in temperatures around 20°C / 68°F.
This is normal and does not require maintenance or servicing.
18 Ranger - OWNER‘S MANUAL
Maintenance
KUBERG motorcycles generally require significantly less maintenance compared to
traditional gas motorcycles due to having very few moving parts, no gas engine and no
exhaust. Our authorized dealers have extensive experience and know KUBERG vehicles
inside and out, so they can provide high-quality service for your KUBERG motorcycle.
However, service at a dealer is not required to maintain your warranty.
WARNING! PROPER MAINTENANCE OF THIS VEHICLE IS REQUIRED
Failure to maintain this vehicle in proper operating condition may lead to an accident
resulting in death or serious injury, and/or damage to property. If you have any questions
about the proper care and maintenance of this vehicle, consult your selling dealer/
distributor or contact KUBERG Customer Service ([e-mail],
[phone].
Before each ride
1Make sure that all bolts and nuts are fastened securely and that the tires are properly
inflated.
2Check that the throttle and brake controls are operating freely.
3Check the primary and secondary chain and if needed, go to page 19 and follow these
steps to adjust their tensions.
4Lubricate both chains with the dry motorcycle chain lube spray, spin the rear wheel
by hand at least 10 times around and remove the excess lubricant using a cloth. If the
wheel does not spin freely, go to page 23 and follow the brake adjustment instructions.
5Once every 2 weeks check the reclining speed of the seat and adjust it according to
instruction on page 21 if needed.

19
This vehicle should be returned for periodic maintenance to your selling dealer AT
LEAST once per year, but more frequently if used under severe or heavy use conditions.
The service log is located at the end of this manual and required when servicing the
motorcycle.
Weather eects on performance
Keep your KUBERG Ranger clean and dry. Regularly check all components for tightness
and adjustment, including handlebars, levers, axles, chain and brakes. Check the settings
for torque and maximum speed. Check the tires for damage and for proper inflation.
Cleaning
Cleaning and maintaining your Ranger correctly will provide more enjoyable ownership
and riding experience. By hand cleaning the motorcycle, you
can simultaneously inspect all of the components. When
cleaning the motorcycle, make sure that the charger port is
closed before washing. While the motorcycle components are
waterproof, be careful when washing the motorcycle around
the electrical components, especially the controller, battery,
motor and throttle. Do not disassemble the motorcycle in any
way before washing. You are free to wash your Ranger with a
water hose or a power wash with clean water and/or motorcycle
cleaner. After cleaning:
1Lubricate the front fork gliders with an appropriate amount
of specialized fork lubricant spray and remove the excess
lubricant using a cloth.
2Lubricate both chains with the oroad motorcycle chain lube spray, spin the rear
wheel by hand at least 10 times around and wait a few minutes for a spray to dry.
3Remove the excess lubricant from fork and chains using a cloth.
WARNING!
Do not use power wash with added cleaner and/or salt as it often consist of a lot of
phosphates that can harm the paint. Do not use engine cleaner.
Maintaining the central double sprocket
and chains tensions
The central double sprocket requies check on a regular basic, especially when riding hard
and/or in harsh conditions. If the sprocket wears out, it’s time for it to be replaced with
botch chains, rear sprocket and pinion gear altogether.
Replacing of the cetral double sprocket and corresponding parts requies further skills and
is highly recommended to be executed by your local service dealer.

Follow these steps to change the central double sprocket:
1Make sure the on/o switch is in OFF position.
2Lift the motorcycle onto a block or stand so that both wheels are o the ground.
3Using the Allen wrench #10 and the open wrench #24 loosen and remove the rear
axle nut. Don’t remove the rear axle yet.
4With the open wrench #10 loosen (screw in) both rear wheel tensioners enought for
the rear wheel to be able to move forward and for the secondary chain to be able to
slip to the outer side of the sprocket.
5Remove the rear axle and the rear wheel, notice the position of 2 silver axle spacers
and 2 black washers. From this point on, do not push the rear brake lever until the
assembly is complette.
6Using the Allen wrench #4 loosen and remove all 7 bolts holding the rear sprocket
from the rear wheel.
7Install the new sprocket and use the new bolts.
Apply a small ammount of thread lock glue on
