occur to the user.
• Always use common sense and safe practices when using the vehicle. The user
must be at least 6 years old and weigh no more than 110 lb (50 kg).The
recommended rider age is only an estimate and can be affected by the rider's
size, weight or skills. Any rider unable to t comfortably on the NexGen should not
attempt to ride it. A parent's decision to allow his or her child to ride this product
should be based on child's maturity, skill and ability to follow rules.
• This product contains small parts that are for adult assembly only. Keep small
children away when assembling.
• Remove and dispose of all protective material and plastic bags before assembly.
• Riders must always wear a tted helmet that complies with U.S. Consumer
Product Safety Commission (CPSC) Standard 16 CFR 1203. Elbow pads and
knee pads, a long-sleeved shirt, long pants, and gloves are recommended.
Always wear athletic shoes (lace-up shoes with rubber soles), never ride barefoot
or in sandals, and keep shoelaces tied and out of the way of the wheels, motor,
and drive system.
• Come to a stop when approaching an obstruction, turn away, and use the vehicle
elsewhere.
• Only sit on the seat on the vehicle.
• Do not allow more than one rider.
• Do not overload the vehicle. Do not remove the weight restriction decals.
• Do not pull the vehicle with another vehicle or similar device.
• Keep body parts, such as hands, legs and hair, and clothing away from moving
parts. Moving parts can cause serious injury.
• Always wear shoes while using the vehicle.
• Do not operate near streets or motor vehicles.
• Do not operate near drop-offs such as steps, steep inclines, or hills. Operate on
relatively level ground.
• Do not operate near water, swimming pools, or other uids.

6Safety
• Do not touch the electric motor when in use as it can become very hot.
• Do not activate the foot pedal throttle unless you are seated and in a safe,
outdoor environment suitable for riding.
• This product was manufactured for performance and durability, but it is not
impervious to damage. Bumping into obstacles, jumping or other aggressive
riding can overstress and damage any product, including the Nighthawk, and the
rider assumes all risk associated with high-stress activity. Avoid bumping into
other objects and obstacles, as this may damage the product.
• Maintain a secure hold on handle at all times.
PREVENT INJURIES AND DEATHS:
NEVER LEAVE CHILD UNATTENDED. ALWAYS keep child in view when child is
in vehicle. Direct adult supervision is REQUIRED.
NEVER use in roadways, near motor vehicles, on or near steep inclines or steps,
swimming pools or other bodies of water.
ALWAYS wear shoes, a helmet and protective gear.
ALWAYS sit on the seat. Do NOT lean back.
RISK OF FIRE. Do not bypass.
• Before using the vehicle, the rider must understand the vehicle controls and
safety issues.
• It is the responsibility of the adult to educate the child and to determine if the child
is capable of understanding the vehicle controls.
• An adult must ALWAYS directly supervise the use of this vehicle.
• NEVER leave a child unsupervised in the vehicle.
• Store indoors when not in use. Store in a dry environment.
• Do not charge at or below 32°F (0°C). Do not store in freezing or below freezing
temperatures. Do not store in temperatures above 86° F (30° C).
• The included lithium-ion battery must be recycled or disposed of in an
environmentally safe manner. Do not dispose of a battery pack in a re; the
battery pack may explode. Do not dispose of the battery pack in your household
trash. The incineration, land lling or mixing of batteries with household trash is
prohibited by law in most areas. Return exhausted batteries to a federal or state
approved lithium-ion battery recycling facility.
• Tampering with or modifying the electric circuit system may cause shock, re or
explosion and it could permanently damage the system. Keep the battery/charger
housing and all electronic components closed to prevent exposed wiring, which
may cause electric shock.
• Battery, charger, electric wire, plug, enclosure and other parts should be
periodically checked for damage. If damage is found discontinue use until the
product is repaired.

IMPORTANT: Before using the vehicle for the rst time, the battery must be charged
for a full 12 hours. To prevent any battery leakage, heat or re, please pay attention
to the following precautions:
• Do not immerse the battery in water.
• Do not use the battery next to high temperature sources, such as a re, a heater,
etc.
• Only use the included charger for lithium battery charging.
• Do not reverse the battery.
• Do not connect the battery directly to the power outlet.
• Do not throw the battery into a re or heater.

car), as this may cause the battery to overheat, cause a re or malfunction, and
result in a shorter battery life.
• Do not use in places with strong static electricity and strong magnets, otherwise it
will easily damage the safety protection device of the battery pack.
• If the battery leaks and electrolytes enter the eyes, do not rub your eyes. Rinse your
eyes with clean water, and go to a hospital for treatment immediately.
• Remove and stop using the battery immediately if it emits a foul odor, overheats, if
there is discoloration, if it becomes deformed or if there is any abnormality during
charging.
• If the terminals of the battery are dirty, use a dry cloth to clean them, to avoid poor
connection.
• Discarded batteries should be covered with insulating paper to prevent re and
smoke.
• The battery should be stored at room temperature, with 40%~60% power. It is
recommended to charge the battery at least once a month, even when the vehicle is
not in use. Failure to recharge the battery periodically may result in a battery that will
not accept a charge. If the product is stored without use for more than a year, it is
