Battery Safety
● Please fully charge the battery before first use. It takes 7 hours.
● Periodically visually inspect the battery connector and charging cable.
● Always keep the charging environment clean and dry.
● Do not charge the e-bike if there is liquid on the charging port.
● Avoid charging your e-bike in extremely hot or cold conditions to take full advantage of the battery's maximum
efficiency. Under no circumstances should you use the bike while it is charging or connected to a charger.
● The charging time is about 7 hours. Prolonged charging may reduce battery life and performance.
● Only use the charger that comes with the e-bike. If the official charger is lost or damaged, Please contact
Customer Service for a replacement.
● Before using the e-bike, Be sure to lock the battery with the provided battery key and remove the battery key.

Description of Button Operations
Button operations include short pressing one button, Long pressing one button, And
long pressing multiple buttons simultaneously.
Short press is used for fast and frequent operations, Such as:
There is no short pressing multiple buttons which is easy to trigger and difficult to
operate.
● 1. In riding, Short press the buttons to change PAS level or speed limit.
● 2. In riding, Short press the M button to switch to multi-function section.
Long pressing the M button is mainly used to switch mode and power on/off.
Long pressing multiple buttons is used for parameter setting, Because the
operation is complicated, It can reduce misoperation.
P14: 1-20A Controller current limit value setting, 12A by default, Range: 1A-20A.
P15: Controller under-voltage setting.
P16: Zeroing: Press and hold the increase button for 5 seconds to reset ODO.
P17: Auto-cruise selection, 0 is no auto-cruise, 1 is auto-cruise; The trigger time for
auto-cruise is set by the controller..
P18: (K5S, APT protocol binding) Forward and reverse power assist selection, 0
forward assist, 1 reverse assist.
P19: (K5S protocol binding) Throttle mode selection, 0 is when you twist the
throttle, The top speed will not change; 1 is when you twist the throttle, The top
speed changes.

For Your Safety
For safe riding, Please read the following information carefully. Before riding, Be sure to
check that your brakes are working properly.
Before Your First Ride
● Check whether the quick-release screws and seat are firm, And whether the brakes
are effective.
● Check seat, Gears, And tire pressure. Proper tire inflation can reduce flat tires and
improve performance, Including distance traveled per inflation.
● Check the handlebar and screws at least weekly.
● Performing the above routine checks before and after each ride can help you keep
your bike performing at peak performance and spot potential problems before they
become a safety hazard.
Bike Mechanic Check Every Six Months
● Bikes require regular maintenance. Take your bike to your local bike shop twice a
year for tuning. Critical components should be inspected frequently, Repaired and
adjusted by an experienced mechanic.
Notice
● Wear an approved helmet and other protective equipment to reduce any possible injury.
● Helmets can reduce serious head injuries by 85%.
● Elbow pads can reduce elbow injuries by 82%.
● Knee pads can reduce knee injuries by 32%.
Warning
● To avoid accidental movement while waiting at a traffic light, set the speed mode to
zero, or apply brakes.
● When riding, Make sure your feet are always on the pedals and your hands on the
handlebars. It is dangerous to take your feet off the pedals in riding.
● Never ride the electric bike for dangerous actions. Failure to exercise good judgment or
heed the above warning increases the risk of serious injury and, In rare cases, death.
● Make sure the battery is fully charged, Especially for long trips.
● For your own safety and the safety of others, Obey the speed limit, Ride at a speed you
are comfortable with, And be prepared to stop at any time.
● Keep a safe distance from other riders to avoid collisions.

17
Battery Maintenance
● Be aware of your surroundings and avoid obstacles and unsafe surfaces.
● Ride in the open and flat. Try to avoid slopes or places with many pedestrians.
● Do not ride at high speeds, On uneven terrains, In bad weather or in other unsafe
conditions.
● Never use the electric bike for anything that could cause personal injury or property
damage.
● Do not attempt to carry passengers or heavy objects. This bike can only hold the weight
of one person at a time. Do not exceed the weight limit.
● Ride e-bikes only where permitted. You must obey local laws and be courteous to
pedestrians.
Notice
● Do not perform any maintenance while the e-bike is powered on or charged.
● Do not store or charge the battery within the temperature range of 20°C-25°C / 68°F-77°F. Do
not pierce the battery.
● Do not attempt to disassemble the battery to avoid fire.
● When the ambient temperature exceeds the maximum operating temperature (See instruction
manual), Do not ride it electric bike.
● Temperature will limit maximum power/torque. Otherwise, Personal injury or property damage
may occur. Before cleaning, make sure the power is turned off and the charging cable is
unplugged. Otherwise, You may damage electronic components. Proper cleaning of your e-bike
can guarantee a longer lifespan and a smoother ride.
● Wipe the outer body of the e-bike with a soft and dry microfiber cloth.
● Check around the wheel to make sure there are no foreign objects. The design of this electric
bike makes wheel maintenance easy.
● The E-Bike has IPX4 water resistance, Which means it can withstand splashes. However,
Don't submerge the E-Bike in water.
A well-maintained battery performs well even after high mileage. Charge the battery
after each ride to prevent the battery from draining from a full charge. Batteries perform
best when used at room temperature (70°F [22°C]). However, Using it at temperatures
below 32°F (0°C) will degrade performance. In general, at -4°F (-20°C), Battery
performance drops to half of that at 70°F (22°C). When the temperature rises, battery
life will resume.
Under normal circumstances, A fully charged battery can hold power for 90 days in
standby mode. Remember to charge the battery after each use. Draining the battery
may cause permanent damage to the battery. Electronics inside the battery record the
charge and discharge of the battery. Damages due to over-discharge or over-discharge
are not covered by the warranty.
Refer to local laws and regulations regarding battery recycling and/or disposal.

18
Storage
Scrap Disposal
Note
● Do not use alcohol, Gasoline, Acetone, Or other corrosive/volatile solvents to clean the bike.
These substances can damage the exterior and the internal structure of the bike.
● Do not allow water and liquids to enter the electric parts or battery of the e-bike.
Notice
Do not store the electric bike outdoors for extended periods of time. Exposure to sunlight and
extreme temperatures (Both hot and cold) Accelerates the aging process of plastic parts and can
reduce battery life.
Store in a cool dry place.
Do not store in dusty environments as damage may occur over time. Cover the bike to prevent
dust from entering.
● This product cannot be disposed of by incineration, Landfilling or mixing with household waste.
Improper handling of the battery in this product may cause the battery to heat, Rupture, Or ignite,
which could result in serious injury. The substances inside the battery pose a chemical risk to the
environment. The end-of-life disposal recommendation for any CYCROWN product is to dispose
of the entire device at an e-waste recycling center or through an e-waste recycling center, Project
or facility.
● Local regulations and laws related to the recycling and disposal of lithium-ion batteries and/or
products containing lithium-ion batteries vary by national, State, And local government. In order
to properly dispose of batteries and/or products containing batteries, You must check the laws
and regulations that correspond to where you live.
● It is the user's responsibility to properly dispose of waste equipment in accordance with local
regulations and laws. For additional information on disposing of batteries and electronics or
electronic waste, Please contact your local waste management office or household waste
disposal service.
The bike should be fully charged before storage to prevent the battery from being over-dis-
charged after long-term storage.
If the electric bike is to be stored for more than a month, Discharge and charge the battery at
least once a month.
