ABOUT THIS MANUAL: This manual was written to help you get the most
performance, comfort, enjoyment and safety when riding your new off-road electric
scooter. It is important for you to understand your new off-road electric scooter. By
reading this manual before you or your child go out on your first ride, you will know
how to get the most from your new off-road electric scooter. It is also important
that your or your child’s first ride on your new off-road electric scooter be in a
controlled environment, away from cars, obstacles, and other riders.
GENERAL WARNING: Riding an off-road electric scooter can be a
dangerous activity, even under the best of circumstances. Proper maintenance of your new
off-road electric scooter is your responsibility and helps reduce the risk of injury. Certain
conditions may cause components to fail without fault of the manufacturer. The off-road
electric scooter can and is intended to move and it is therefore possible to lose control, fall
off and/or get into dangerous situations that no amount of care, instruction or expertise can
eliminate. If such a thing does occur, you can become seriously injured or die, even when
using safety equipment and other safety precautions.
RIDE AT YOUR OWN RISK AND ALWAYS USE COMMON SENSE.
This manual contains many warnings and cautions concerning the consequences
of failing to inspect, maintain or properly use your off-road electric scooter.
Because any fall can potentially result in serious injury or even death, we do not
repeat the warning of possible serious injury or death each and every time the risk
of falling is mentioned in this manual.
ALWAYS USE PROPER SAFETY EQUIPMENT AND RIDING ATTIRE
Always use appropriate safety equipment, such as a helmet, elbow pads, knee
pads, gloves, and wrist guards. A helmet is not only a good idea but may be legally
required in your community. To protect yourself or your child, the helmet must meet
CPSC, 16 CFR 1203, requirements and be worn correctly:
INTRODUCTION, SAFETY AND WARNINGS

Always wear appropriate clothing and shoes, including long sleeved shirts and long
pants and lace-up or similar shoes with rubber soles. Never ride barefoot or in sandals
and make sure that shoelaces or other fasteners are tied and kept away from the wheels
and drive system of the off-road electric scooter.
RIDER USE AND REQUIRED PARENTAL SUPERVISION
RIDERS MUST NOT EXCEED THE WEIGHT LIMIT OF 220LB (100 KG).
The age grade for the off-road electric scooter is for ages 14 and older. Just because
some one is within the age and weight limitations specified for the off-road electric
scooter, does not mean that his/her size is appropriate to fit or maintain control of
the off-road electric scooter or that he/she is capable of safely operating the off-road
electric scooter. You are the best judge of whether you or your child can safely operate
the off-road electric scooter; this includes determining whether your child is at the
appropriate developmental stage for safe use of the off-road electric scooter. Any rider
that is unable to fit comfortably on the off-road electric scooter should never attempt to
ride it. A parent’s decision to allow their child to use the off-road electric scooter should
be based on the child’s maturity, skill and their ability to follow rules. Keep this off-road
electric scooter away from small children and remember that it is intended for use only
by persons who are, at a minimum, able to comfortably and safely operate the off-road
electric scooter.
Children operating the off-road electric scooter should be supervised by an adult at all
times. Parents should ensure that children only use the off-road electric scooter safely
and within their age and physical limits.
This manual contains very important safety information. It is your responsibility to
completely review this information and make sure that all riders understand all of the
warnings, cautions, instructions and safety topics addressed in this manual and to
assure that all riders are able to safely and responsibly use the off-road electric scooter.
You should periodically review and reinforce all information in this manual with all riders,
especially children. You should also regularly inspect and maintain your off-road electric
scooter to insure the safety of all riders. Make sure that your new off-road electric
scooter is properly fitted to any child riding it; that it is in good repair and safe operating
condition; that you and your child have gone over the use, operation and safety
information in this manual; that you and your child have learned and understand what

INFLATING FRONT AND REAR TIRE:
Tires are inflated before shipping, but they
invariably lose some pressure between the
point of manufacturing and your purchase.
Using a bicycle style tire pump for a Schrader
valve, inflate the tires to the PSI indicated on
the sidewall of the tires.
CHARGING THE BATTERY:
1. Turn power OFF before charging. Plug the
charger into the charger port on the off road
electric scooter.
Your off-road electric scooter may not have a fully charged battery. Therefore it is a
good idea to charge the battery prior to use.
Initial charge time: 18 hours, and never charge the battery longer than 30 hours.
Recharge time: up to 12 hours, and never charge the battery longer than 30 hours.
When the off-road electric scooter is not in regular use, recharge the battery at least
once a month until normal use is resumed.
Run time: Up to 45 minutes of continuous ride time.
Average battery life: 250 charge/discharge cycles.
NOTE: Be sure to properly align the groove
on the charger input plug with the
corresponding socket on the case; otherwise,
no charging action will occur.
CAUTION: Use of pressurized air supplies such as those found at service
stations is not recommended and if not used properly, may cause a tire to blow
out. If you do use a service station pump, make sure the pressure gauge is working
and then use very short bursts of air to inflate the tire to the correct PSI, taking
care to avoid sudden over inflation. If you exceed the recommended PSI, release
the excess pressure immediately.

13
WARNING: Rechargeable batteries are only to be charged under adult
supervision. Always disconnect your off-road electric scooter from the charger
before cleaning with liquid.
2. Plug the charger into a wall power outlet. The
light on the charger housing shouId illuminate.
A red LED light indicates the battery is
charging and a green LED indicates the
battery is fully charged. (If the lights on the
charger do not light up, check the power to
the outlets. If necessary, try a different
electrical outlet).
NOTE:
• Turn off key power switch when not in use.
• Batteries may become damaged and could no longer accept a charge, if switch is
left in the ON position when not in use.
• Fully charge the battery before storage
NOTE: Failure to recharge the battery at least once a month may result in a battery
that will no longer accept a charge.
NOTE: If your charger does not look like the one illustrated, your unit has been
supplied with an alternative charger. The specifications and charging procedure
would not change. The charger has a small window with one LED or two LEDs to
indicate the charge status. Refer lo the illuslration on the charger unit for the actual
‘charging ” and “charged” status indications for your model charger. Chargers
have built-in overcharge protection to prevent the battery from being over-charged.
Charger will get warm during use. This is normal for some chargers and is no cause
for concern. Ii your charger does not get warm during use, it does not mean that it is
not working properly.
WARNING: Charging produces explosive gases. Charge battery in a well
ventilated area, away from sparks, flames, smoking and combustibles.

BEFORE YOU RIDE
Before you ride always check the following:
Safety Gear: Always wear proper protective gear such as:
• Approved safety helmet. (Helmet may be legally required by local law or
regulation in your area.)
• Elbow pads, knees pads and wrist guards
• Long sleeved shirt, long pants
• Gloves
• Lace up shoes with rubber soles
Brakes: Check the brake for proper function. When lever is squeezed it should
slow/stop the rear wheel without excessive effort. When you apply the brake with
the throttle on, the brake cut off switch should stop the motor. Make sure that the
brake is not rubbing when the lever is not being squeezed. Do not ride the off-road
electric scooter if the brake is not functioning properly.
Throttle: Once the power switch is placed in the “ON” position, twist the throttle
to engage the motor; the off-road electric scooter will move. Make sure that before
the throttle is twisted you are in an open and safe area to ride, you are balanced on
the off-road electric scooter and have both hands on the handlebar controls.
Tires: Inspect the wheels/tires for excess wear and replace if necessary. Regularly
check the tires pressure and re-inflate as necessary.
Frame, Fork and Components: Always carefully inspect your off-road electric
scooter before you ride. Check for cracks, broken, worn or loose components
which should be repaired or replaced before your ride.
Battery: Always make sure the power switch is in the “off” position whenever the
vehicle is not in use. Never store the product in outdoor conditions, never store it
in the rain, and never store the product in freezing or below freezing temperatures.
These low temperatures will permanently damage the battery.
WARNING: Your off-road electric scooter comes with a variable speed
throttle. Always remember to twist it slowly or gradually; DO NOT quickly twist the
throttle to its end until you feel comfortable on the off-road electric scooter and
with your speed. If you twist the throttle quickly at first, you will accelerate rapidly
and may get thrown from the off-road electric scooter and risk serious injury or
death. (Doing it will also decrease your battery life).
WARNING: Always ensure that you are in a safe flat open area to ride
before you engage the throttle. Never twist the throttle without being on the
off-road electric scooter in a balanced, ready to ride position with both hands on
the handlebar controls. Failure to follow these instructions may damage your
off-road electric scooter and void your warranty.
WARNING: An off-road electric scooter that does not work properly can
cause you to lose control and fall. Inspect the entire off-road electric scooter
thoroughly before every ride, and do not ride the off-road electric scooter until any
problem has been corrected.

15
WARNING: Do not ride over hills, slopes, or inclines.
WARNING: Do not ride on rainy days, over ice, or on wet and
slippery ground.
WARNING: Please inflate tires to tire pressure suggested.
WARNING: Do not ride over soft, debris, sand, grass, or any
tough surfaces, they will burn your scooter controller.
NOTE: Turn the power “Off” when not in use! Otherwise it will drain
and damage your battery!

DETAILED MAINTENANCE & REPAIR
WARNING: Turn the power switch “OFF” before
conducting any maintenance procedures.
Testing the Brakes
To use the brake, squeeze the lever to increase the pressure on the brake. The
brake lever is fitted with a cable adjuster to compensate for cable stretch and/
or to fine-tune the lever movement to brake engagement. If brake is not engaging
properly, follow instructions for adjusting the brakes.
Adjusting the Brakes Tools required; 10mm wrench (not included)
1. To adjust the brake cable tension, turn
the adjusting barrel on the brake lever
clockwise (to loosen) or counter-clockwise
(to tighten). Only turn the adjusting barrel in
small increments until the desired adjustment
is reached. If the brake continues to need
adjustment, proceed to the next step.
WARNING:Keep brakes properly
adjusted and in good working condition at all
times. Check to make sure that the brakes
are functioning properly after any adjustment
and before riding.
2. If the brake cable is still either too tight or too loose, use a 14mm open end
wrench to adjust the brake.
• Please set the power switch to “OFF” position.
• Use something to hang the rear wheel for brake adjusting.
• Use your hand to spin the rear wheel, if it can spin freely and loosely that means
you can tighten it to adjust. Turn the adjusting barrel clockwise, and every one
cycle you turn the barrel, just spin the wheel and feel with your hand if the rear
wheel will rub the brake mechanism, if it does not rub, please turn the barrel
another cycle, until you feel them rub. Then please turn the barrel one cycle back
(counter-clockwise), your vehicle has been adjusted well now.
• If when you spin the rear wheel it does not spin smooth, you can turn the
adjusting barrel counter-clockwise, and every one cycle your turn the barrel, just
spin the wheel and feel with your hand if the rear wheel will rub the brake any
more, until you finish the brake adjusting.

the scooter.
Note: After a certain time of riding, if thickness of your brake shoe is wear and
thinner, only adjusting the brake cable would not help you to solve the issue,
you can follow below steps for further adjustments. (Our advanced rear brake
have total 4 levels to allow you adjusting after long time usage, it is at level 1
stage when you started to use your new off-road electric scooter.)
- Remove the rear wheel off for further adjusting (see page 19-20 on how to
remove rear wheel off), use 10mm wrench to loosen the bolt as shown;
- Use this 10 mm wrench to move the bracket clockwise so that the small dot
facing 2, then re-mount the rear brake with the rear wheel for better riding.
Hints: If the rear brake shoe no longer allows further adjustment (usually after
approximately four adjustments), you will need to replace the rear brake.
• Test to see if your brake functions well:
when you spinning the rear wheel, squeeze
the brake lever with another hand 5-10mm,
so see if the rear wheel can still spin by
hand, if it does not spin, that means your
brake is working well.
