WELCOME TO THE QUALISPORTS USA FAMILY
Thank you for purchasing a Quali-bike.
Please read this Owner’s Manual carefully before setting up
your bicycle and riding. You should become thoroughly
familiar with the proper operation of your Quali-bike, its
features, capabilities, and limitations. To ensure a long, trouble-
free life for your Quali-bike, provide it with the proper care and
maintenance as described in this manual. Of course, it is not
practical or possible to warn you about all of the hazards
associated with operating or maintaining your Quali-bike. For
this, you must use your own good judgment.
For replacement parts and accessories, you should always use
Qualisports USA-approved parts. As they have been specially
designed for your bicycle and manufactured to meet
Qualisports USA’s demanding standards.
This manual should be considered a permanent part of your
bicycle and should remain with the bicycle when it is sold.
If you need any assistance, please do not hesitate to reach out
to us.
Enjoy the ride!

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 www.qualisports.us/user-manual 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: To reduce the risk of injury, close supervision is necessary when the product is used near children.
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.

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 Rad
Power Bikes 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.
