Electric Balancer Pre-Riding Safety
CAUTION: For your safety you must carefully read this manual and
follow its instructions. Your bicycle may come with additional instruction
sheets that cover features unique to your bike. Please ensure that you read
and become familiar with their contents and retain them with this manual
for future reference. Remember bicycles, in most areas, are subject to the
same laws, rules, and regulations as motor vehicles.
Always wear a CPSC approved helmet when riding your bike.
Learn and follow local and state trac use laws.
Any major service or adjustments on your bike not covered in this manual
should be carried out by a professional bicycle mechanic. If you wish to
make adjustments yourself, this manual contains important tips on how to
do it.
CAUTION: Any adjustments you make are entirely at your own risk. Do
NOT use your bike for freestyle and stunt riding, jumping or competitive
events. Do not ride your bike when any part is damaged or not working
properly. You must, for your safety and the safety of other users, consult a
professional bicycle mechanic for any questions on repairs or maintenance.
WARNING: As with all mechanical components, the bicycle is subjected
to wear and high stresses. Dierent materials and components react to
wear or stress fatigue in dierent ways. As your bicycle ages, you should
inspect it more frequently to look for deformed, cracked, bent, or loose
components. Such conditions may lead to sudden failure. is may
possibly cause injuries to the rider. If something is cracked or broken,
do not ride until repairs have been made.

Electric Balancer Pre-Riding Safety
BEFORE RIDING
1. WARNING - ON AND OFF ROAD CONDITIONS: e condition of the
riding surface is very important to your safety. If the surface is wet, or has
sand, leaves, small rocks or other loose debris on the surface where you
plan to ride, carefully decrease the speed of the bicycle and ride with extra
caution. It will take a longer time and more distance to stop. Apply the
brakes sooner and with less force. Always apply the rear brake rst allowing
time and distance for it to take eect. en follow by cautiously applying the
front brake, in order to maintain control of the bicycle. Rapid front brake
application rst may cause a front pitch over or fall. Learn to use your brakes
properly under controlled conditions until you learn proper braking under
all road conditions.
2. NOTICE: State and federal regulations require a full set of reectors.
Some state and local laws may require that your bike be equipped
with a warning device, such as a horn or bell and most states require a
light. e manufacturer and many legal authorities DO NOT approve or
encourage riding at night. Vision is quite limited at dawn, dusk and at night
for bike riders, motorists and by-standers. If you must ride at night, take
extra precautions, use front and rear lights, wear ashers on your arms,
wear light-colored clothing, and plan your route to ride in well lighted areas
avoiding heavy trac areas.
3. NOTE: Always wear shoes when riding a bicycle and avoid loose
tting clothes. Wear a cu band or trouser clip to keep pants or other loose
clothing from getting caught in the chain wheel. Long sleeves, long pants,
gloves, eye protection, a CPSC approved helmet, elbow and knee pads are
recommended. Helmet use is required by law in many states and is always a
good idea for your safety.

Electric Balancer Pre-Riding Safety
4. CAUTION: WET WEATHER WARNING: Check your brakes frequently.
e ability to stop is critical to your safety. Roads are slippery in wet weather
so avoid sharp turns and allow more distance for stopping. Brakes become
less ecient when wet. Leaves, loose gravel and other debris on the road
can also lengthen stopping distance. If at all possible, do not ride in wet
weather. Vision and control are impaired, creating a greater risk of accidents
and injury.
5. CAUTION: A bicycle rider’s best defense against accidents is to be alert
to road conditions and trac in the area. Do not wear anything that restricts
your vision or your hearing.
6. When riding, ALWAYS WEAR A APPROVED BIKE HELMET. It may save
your life.
7. Obey all trac regulations. Most trac regulations apply to bike riders as
well as automobile operators. Observe all state and local trac regulations,
signs and signals. Check with your local police station on bicycle licensing
and inspection, and where it is legal to ride your bike.
8. ON AND OFF ROAD OPERATION: Avoid the following road hazards: drain
grates, pot holes, ruts, so road edges, gravel, leaves (especially when they
are wet), uneven pavement, railroad crossings, manhole covers, curbs, speed
bumps, puddles, and debris as all have an eect on your riding and may
result in loss of control. Adjust your speed and the way you use your brakes
if you must ride in such areas.
9. If any components become loose while riding, (STOP!!) immediately and
tighten, or bring to a mechanic for repair.

Electric Balancer Pre-Riding Safety
TO AVOID INJURY, THIS PRODUCT MUST BE PROPERLY ASSEMBLED
BEFORE USE. WE STRONGLY RECOMMEND THAT YOU REVIEW THE
COMPLETE ASSEMBLY GUIDE AND PERFORM CHECKS SPECIFIED IN
THE OWNER’S MANUAL BEFORE RIDING.
Just a minute spent before each ride can signicantly improve your safety
and the enjoyment of your ride. So, EACH TIME before you ride make a
habit of performing the following safety checks:
• Stand in front of the bicycle facing rearward and hold the front wheel
securely between your legs.Try to twist the handlebar and verify that they do
not move. en pull the handlebars up, trying to li the bike. ere should
be no movement.
• Try to push the front wheel from side to side and conrm that it feels tight
and will not wobble. Li the front wheel up by the handlebars and strike the
wheel downward with the heel of your hand to conrm that it is securely
attached to the wheel. Spin the front wheel and conrm that it does not
wobble or contact the fork or brake pads.
• Try to li/push down on and twist the seat to conrm it is tight.
• Look at the connection of the pedals to the crank arm. You should not see
pedal screw threads and the pedal should feel rm and be parallel to the
ground.
• Apply your brake(s) and make sure they feel rm to the touch, and then
spin the wheel(s). Apply the brakes. e brakes should stop the wheel(s).
• Check to be sure that the fenders and accessories (if equipped) are rmly
attached and will not contact any moving parts. Make sure all reectors are
in position and not broken.
Now, put on your BICYCLE SAFETY HELMET and enjoy your ride. Your
safety is well worth just a minute. Also, be sure to read and follow the warn-
ings and instructions in this manual

SAFETY EQUIPMENT
umpstar promote the use of safety equipment during the use of your
electric balancer; the following list is an advisory guideline of the equipment
that should be obtained before using your electric balancer for the rst time,
and to be used for every ride regardless of experience and skill level.
HELMET
EYE PROTECTION
GLOVES
FOOTWEAR
CLOTHING
A helmet is the most important piece of protective equipment and
should be worn at all times the electric balancer is being ridden.
Ensure the helmet ts the operator snugly, is securely fastened and
provides good, all-round visibility. A poorly-tting or loose helmet
can become dislodged in an incident and then oer no protection
at all.
Recommended to prevent eye injuries and prevent branches, bugs,
dust or sand hitting your face and distracting you. Sunglasses are
unlikely to provide adequate physical protection.
Arms and legs should be covered to reduce abrasions to the body,
even in hot weather. Trousers should be close-tting and in good
condition.
Sturdy footwear is recommended

Message To Riders
Your safety is very important to umpstar. at’s why we urge you to
read this message before riding this electric balancer. You can help prevent
accidents by making good decisions about if, when, and how you ride this
electric balancer.
THINGS TO CONSIDER WHEN RIDING
e rst decision you’ll need to make is whether you’re ready to ride. Riding
readiness varies widely from one person to another, and age and size are not
the only factors.
PHYSICAL ABILITY
An important consideration is that riders must be big enough to hold the
electric balancer up, get on, and comfortably sit on the seat with both feet
touching the ground. ey should also be able to easily reach and
work the brakes, throttle, and all other controls.
If you decide that you’re ready to safely operate this electric balancer,
make sure you carefully read and understand the owner’s manual
before riding. Also be sure that you have a helmet and other
appropriate riding equipment, and always wears it when
operating the electric balancer or sitting on it.
SAFE AND RESPONSIBLE RIDING
When you put safety rst, you can enjoy more peace of mind, and
you can enjoy more hours of safe oroad riding.

Loading, Accessories & Modifications
umpstar designed a rider-only electric balancer. It was not designed
to carry a passenger or cargo. A passenger or cargo could interfere with
your ability to move around to maintain your balance and control of
the electric balancer.
In addition, exceeding the weight limits or carrying an unbalanced load
can seriously aect your electric balancer’s handling, braking, and stability.
Adding accessories or making modications that change this
electric balancer’s design and performance can also make it unsafe. Also,
the weight of any accessories will reduce the maximum load the
electric balancer can carry
We recommend that you do not carry any cargo on this electric balancer.
ACCESSORIES & MODIFICATION
Modifying your electric balancer or using non-umpstar accessories can
make your electric balancer unsafe.

Loading, Accessories & Modifications
ACCESSORIES
We strongly recommend that you use only umpstar Genuine Parts and
Accessories that have been specically designed or approved and tested for
your electric balancer. Because umpstar cannot test all other accessories,
you must be personally responsible for proper selection, installation, and
use of non-umpstar accessories. Check with your dealer for assistance
and always follow this guideline:
Make sure the accessory:
- Does not reduce ground clearance and lean angle
- Limit steering travel
- Alter your riding position
- Interfere with operating any controls
MODIFICATIONS
We strongly advise you not to remove any original equipment or modify
your electric balancer in any way that would change its design or operation.
Such changes could seriously impair your electric balancer handling,
stability, and braking, making it unsafe to ride.
We also advise you not to make any modications or remove any equipment
that would make the electric balancer illegal in your area.

Operating and Riding the Electric Balancer
IMPORTANT INFORMATION
Non-powered training: We recommend that you teach your child how to
balance the Balancer rst before you add power. ey should be procient
at kicking and balancing the Balancer before turning the power switch
on. ere are many videos on YouTube which can teach them to kick and
balance.
POWER MODE
e 12in comes in the lowest settings and ½ power. We programmed the
beginner mode so that the balancer does not move too fast and you can
briskly walk next to your child while training. e throttle is not very
responsive and has a delay built in and takes a few seconds to start moving.
Once they kick or you push them, it will start to move and will slowly gain
speed as it goes. is is a safety feature built in so that the Balancer does
not start too fast. is feature changes when you go to faster modes.
We leave the speed cap o so that you can adjust the speeds. Aer you have
chosen a safe setting for your child’s skill level, we recommend you cover
the switch (cover is in the tool bag) so they cannot change the mode and go
faster.
e illustrations below show you the dierent positions of the speed switch
located on the bottom of the frame. As mentioned above, the 12in comes
with 50 % power,50% torque, kick-start and the slowest speed setting. To
change to 100 %power, full torque, non-kick mode - please refer to the next
page.
WARNING: It is recommended that once you change to full-power
mode, you monitor your child and make sure that they can operate the
Balancer safely. We recommend that you change 1 mode at a time.
