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 every effort to ensure the accuracy of its documentation and assumes no 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.

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
Notice: Before every ride, and after every 25-45 miles (40-72 km), we advise following the pre-ride safety checklist.

Safety Check 1. Brakes

Basic Steps
Ensure front and rear brakes work properly. Check brake pads for wear and ensure they are not overworn. Ensure brake pads are correctly positioned in relation to the rims. Ensure brake cables are lubricated, correctly adjusted, and display no obvious wear. Ensure brake levers are lubricated and tightly secured to the handlebar. Test that the brake levers are firm and that the brake, motor cutoff functions, and the brake light are functioning properly.

2. Wheels and Tires

Ensure battery is charged before use. Ensure there is no damage to battery. 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.
