INTRODUCTION
Before using your Quali-bike, please read this manual noting the sections on
safety and folding in particular. While this manual is intended as a guide, it
is not a comprehensive guide to cycling or bicycle maintenance.
Keep this manual, along with any other documents that were included with your
bike, for future reference, however all content in this manual is subject to
change or withdrawal without notice.Visit https://www.qualisports.us/pages
/user-manuals to view and download the latest version. Qualisports USA makes

responsibility or liability if any errors or inaccuracies appear within.
Assembly and first adjustment of your bike from Qualisports USA requires
special tools and skills and it is recommended that this should be done by a
certified, reputable bike mechanic if possible.
Because it is impossible to anticipate every situation or condition that can
occur while riding, this manual makes no representations about the safe use of
bikes under all conditions. There are risks associated with the use of any
bike that cannot be predicted or avoided and are the sole responsibility of
the rider.
We recommend having your bike inspected and serviced by a Qualisports USA
dealer regularly.
WARNING: Incorrect assembly, maintenance, or use of your e-bike can cause
component or
performance failure, loss of control, serious injury, or death. Even if you’re
an experienced bike rider, you must read and understand the entire manual and
any documentation provided for subcomponents or accessories before riding. If
you are not sure you have the experience, skills, and tools to correctly
perform all assembly steps in the manual and the assembly video at
www.qualisports.us, consult a local, certified, reputable bike mechanic.
WARNING: To reduce the risk of injury, close supervision is necessary when the
product is used
near children.
WARNINGS
Guard against rust, water damage, and corrosion
Like any vehicle used outdoors, your e-bike needs the care to ensure it isn’t
damaged by the elements. Follow these steps for a long, healthy life for your
e-bike: · Store under shelter and in an upright position; avoid leaving the
bike in the rain or being
exposed to corrosive substances such as water, salt, or de-icing. If exposed
to rain, dry your bike afterward, and apply an anti-rust treatment to the
chain and other unpainted steel surfaces. · To clean your e-bike, turn the
bike and battery off and wipe the frame with a clean, damp cloth. If needed,
apply a mild, non-corrosive detergent mixture to the damp cloth and wipe the
frame. Dry by wiping with a clean, dry cloth. Never use high-pressure water on
your bike. Wipe down your bike frequently and wipe or spray all unpainted
mechanical parts with anti-rust treatment. · Use touch-up paint or nail polish
to prevent rust if painted metal parts become scratched or chipped. · Never
immerse or submerge the bike or any components in water or liquid, which can
damage the electrical system. Avoid riding on the beach, coastal areas with
high-salinity fog, or on surfaces treated with salt or de-icing compounds.
Doing so exposes your bike to salt or other substances that are very
corrosive. Corrosion of electrical components can lead to permanent,
irreversible damage that can cause battery failure, electrical system failure,
or electrical fire. Damage from corrosion is not covered under warranty.
WARNING: Damage to your e-bike’s electrical system caused in any manner,
including water
intrusion, can lead to battery failure, electrical system malfunction,
electrical fire, and consequent property damage, injury, or death. Follow all
recommendations to minimize the chance of water damage. If you have any
questions, contact Qualisports USA Product Support.
WARNINGS
Additional precautions regarding electrical components
CAUTION: To reduce the risk of fire, connect only to a circuit provided with
10 amperes maximum branch circuit over-current protection in accordance with
the National Electrical Code, ANSI/NFPA 70.
WARNING: Using a damaged battery or charger can create additional bike damage
or a fire hazard. Stop using your battery and charger and contact Qualisports
USA immediately if any of the following occur (1) Your charger’s flex- ible
power cord or output cable or any of the electrical cables on your bike is
frayed, has broken insulation, or any other signs of damage, (2) Your battery
or charger is physically damaged, non-functional, or performing abnormally,
(3) Your battery or charger experienced a significant impact from a fall or
crash, with or without obvious signs of damage, or (4) Your charger becomes
too hot to touch (it’s designed to get warm with normal use), makes a funny
smell, or shows other signs of overheating. Store any damaged battery or
charger in a safe location and, as soon as possible, recycle or otherwise
dispose of it according to local rules. Contact Qualisports USA if you have
any questions or to purchase a compatible replacement battery or charger.

Important safety information
Don’t ride until you read this
Before riding your Quali-bike for the first time, and periodically thereafter,
please pay close attention to the following: · We recommend the use of an
approved cycling helmet, even in countries where their use is not mandatory. ·
Before riding your Quali-bike on open roads, please take time to familiarize
yourself with the operation of the bicycle and electric
assist system in a quiet place, away from traffic or hazards. · Please fully
charge the battery before the first use. · Read and follow e-bike regulations
on and off road. · Always keep both hands on the handlebar grips and the brake
levers so they are within reach while riding. · Do not ride distracted. Always
remain alert to all riding conditions. Never use headphones or a cell phone to
talk or text when
riding. · Always ride defensively. Watch out for potential obstacles that
could force you to swerve suddenly or lose control. Braking while
steering may reduce your ability to control your bicycle. · Look ahead and
brake sooner. You may be moving faster on your e-bike. Other road users may
not expect you to be traveling at
higher speeds. Riding faster may increase your risk of a crash. · Stop
pedaling well before approaching corners to avoid entering a corner too
quickly. You should also pay particular attention to
terrain conditions as you may approach obstacles faster than expected. · Use
caution when riding in wet conditions as it will take longer to brake and to
stop. Your tires may slip when turning. Risk of a
crash is dramatically increased in wet conditions. · Your electric bicycle can
withstand light rain and small splashes, but it is not designed to be
subjected to inclement weather,
extremely heavy showers, or submersion in water. The electric bike’s
components have an IP rating of 65. Water damage is not covered under the
warranty. · Riding at night comes with more risks than riding during the day
due to decreased visibility; riders are encouraged to exercise increased
caution in nighttime conditions. · Riders should wear reflective clothing at
night. Turn lights ON for safety. For increased visibility, ensure that the
front headlight and rear taillight are turned ON and adjusted so that other
people on the road can see them clearly. Also, check your front, rear, and
wheel reflectors.

How to charge your battery/batteries
Some instructions on battery maintenance and charging
1. Please charge the battery for 1-2 hours after its energy is consumed for
50%-70% of its total energy, in this way, the battery life will be longer. If
you leave the battery pack in your stock in less energy condition, it will
sleep to die quickly.So please charge the battery pack full after each long-
distance ride. Do not charge the battery over a long time (longer than 10
hours) in summer; in case the battery will be calorifacient and broken.
2. Recharging the battery once a month during the period of storage. 3. It is
recommended that you store the battery at a temperature between 0-40 degrees
Celsius which is
32-104 Fahrenheit. 4. The battery pack might not be fully charged when the
temperature is over low or over high. When the
battery is charged, its temperature may become a little higher, it is expected
under the temperature of 50(122.00). If the charger indicator is useless when
the battery is fully charged or the battery is scorching [that exceeds
50(122.00)], please come to the seller to find maintenance at once. 5. Do not
make the charger jolty in the rear box if there is one box attached, and the
charger should be far away from water. The impact and shake should be at the
lowest degree when the battery is moved. 6. It’s also important that you only
use the charger that the manufacturer supplied since it will have been
specifically designed for the battery. Using a different charger runs the risk
of causing a fire and could damage the battery. 7. You should also take
measures to protect the battery from being water damaged. Even though electric
bikes can be cycled in the rain it doesn’t mean that they are waterproof so,
you should take some precautions to ensure that the location where you store
the battery in isn’t at risk of flooding or high humidity. 8. Please ensure no
short-circuit in your wall socket for fear of burning out the battery and
causing danger.
16 Pre-ride safety checklist

Lock battery to frame and ensure that it is secured. Charge and store bike and
battery in a dry location, between 50 °F 77 °F (10 °C 25 °C). Let bike dry
completely before using again.
Look over connectors to make sure they are fully seated and free from debris
or moisture. Check cables and cable housing for obvious signs of damage.
Ensure headlight, taillight, and brake light are functioning, adjusted
properly, and unobstructed.
12. Accessories
Ensure all reflectors are properly fitted and not obscured. Ensure all other fittings on bike are properly secured and functioning. Inspect helmet and other safety gear for signs of damage. Ensure rider is wearing a helmet and other required riding safety gear. Ensure the mounting hardware is properly secured if fitted with a front rack, rear rack, basket, etc. Ensure the taillight is properly secured after the saddle installed. Ensure fender mounting hardware is properly secured if fitted with fenders. Ensure there are no cracks or holes in fenders if fitted with fenders.
Your cables, spokes, and chain will stretch after an initial break-in period of 50-100 mi (80-160 km), and bolted connections can loosen. Always have a certified, reputable bike mechanic perform a tune-up on your Quali-bike after your initial break-in period of 50-100 mi (80-160 km) (depending on riding conditions such as total weight, riding characteristics, and terrain). Regular inspections and tune-ups are particularly important for ensuring that your bike remains safe and fun to ride.

It`s usually due to the cable on the throttle is being pulled too tight.
Please rotate the thumb throttle forward and backward in the position of the
handlebar, to let the cable of the throttle relax a little bit.
You need to see if the motor cable connector on the frame and in the
controller box is loose. Unplug the motor connectors and plug them back
together and try again.
