Important to read before the rst ride
Supplemental Product Information
The most important points for you to do
1. Even if you have ridden a bicycle for years, it is important for every person to read
the general ‘Bicycle Owner’s Manual’ and the specic ‘E-Bike Owner’s Manual’
carefully before you ride on the new e-bike.
• Both manuals contain detailed information and useful suggestions about your new
bicycle.
• Make sure that you understand the proper use, maintenance and disposal of the
components of the electrical system of your new e-bike.
2. Think about safety. Your safety and that of other road users is very important.
• Check your bicycle for normal operation, loose parts and defects before riding.
If you nd any problem, visit your authorised bike shop for repairs before riding.
• Be aware that other road users (cars, vans, motorcycles) do not expect that an e-bike
can ride faster than a normal bicycle. Riding faster also increases the risk of accidents.
Distances will close much faster and braking distances will become longer.
• Do not ride abusively. Only ride in the use conditions specied for your bicycle.
Please refer to the Use conditions table in the general Bicycle Owner’s Manual.
3. The electric system of your new bicycle needs special attention.
• Do not clean your e-bike with a high-pressure washer. Any electrical system is sensitive
to moisture. High-pressure water might enter connectors or other parts of the electric
system.
• Do not allow a Li-Ion battery (separately or integrated in the downtube) to su󰀨er any
mechanical or physical impacts or make any internal modications. In an extremely
rare case, a battery that has been severely impacted or otherwise mishandled could
potentially catch re. If you suspect damage to your battery, visit your local authorised
bike shop immediately for inspection.
4. Maintain the battery as instructed in this E-Bike Owner’s Manual.
Failure to follow these instructions may result in damage to your battery and may require
battery replacement:
• Only charge the battery with the included charger.
• Charge the battery indoors or in a garage at room temperature to avoid exposure to
rain or wind.
• When you do not use the e-bike for an extended period of time, charge the battery to
80% to meet the optimum storage condition. Check the charge level again after six
months. If the remaining charge of the battery is less than 30%, charge it again to 80%.
Once charging the battery is complete, unplug the battery from the charger and unplug
the charger from the wall socket.
• Your e-bike has a built-in Li-Ion battery. Any Li-Ion battery will self-discharge over time.
If the battery is left uncharged, then stored without charging, it may discharge to such
a low state that the battery can no longer be charged and must be replaced.

• Store the e-bike in a dry, well-ventilated location. Protect the battery against moisture
and water.
• The battery can be stored at temperatures between (minimum) -20°C (-4°F) and
(maximum) +50°C (122°F). For a long battery life, however, it is best to store the battery
at room temperature of approximately 20°C (68°F).
5. Be careful when transporting an e-bike.
• An e-bike is heavier than a normal bicycle. If transporting on a vehicle, be aware of
the maximum load capacity of the vehicle’s roof, towing hitch and/or the bicycle carrier.
Refer to the manuals of the vehicle and bicycle carrier for details.
• Always respect local laws about transportation of an e-bike.
Because Li-Ion batteries of this size and power are considered ‘Dangerous goods,
class 9’ when transporting, regulations may restrict the transport of separate Li-Ion
batteries in some places. Before booking your trip, make sure to check ahead with
your airline or carrier if it is allowed to travel with your complete e-bike.
6. Obey local regulations.
In most countries, the regulations for the use of an e-bike are the same as those for a
standard bicycle. However, there may be local di󰀨erences such as where you can ride,
minimum rider age or required equipment and registration.
It is the rider’s responsibility to know the local regulations that apply to an e-bike and
to obey them.
7. Visit your bike shop on a regular basis for maintenance of your new bicycle.
Your bike shop has the right knowledge and equipment to maintain your e-bike.
If you have questions about your new e-bike, ask your local authorised bike shop.
Limited warranty
Your bicycle is covered by a Limited Warranty.

1. Introduction
Thank you for choosing your new e-bike with the Hyena riding assist system.
We sincerely hope that you will enjoy your ride.
This owner’s manual is intended for the user to operate the product and contains details of
the assist system.
1.1. Important notices
⚠ WARNING
Please carefully read all of the safety warnings and instructions throughout the manual.
Failure to follow these warnings and instructions could result in severe injury or death.
• Users who are not professionally trained for bicycle assembly should not attempt to install,
disassemble or modify components.
• If you have any concerns about the operation of the assist system or its components, or
if you suspect damage to the battery, visit your local authorised retailer immediately for
an inspection.
• The term ‘battery’ in this manual also applies to the (optional) range extender battery and
can in some cases apply to both batteries with the range extender installed on the e-bike.
► About Warnings Symbols
As you read this manual, you will see grey warning boxes like this:
⚠ WARNING
Text in a grey box with the safety alert symbol will warn you about a situation or behaviour
that could cause severe injury or death.
► About Images
The e-bike shown in this manual may di󰀨er visually from your Hyena-equipped e-bike.
All information provided in this manual is still applicable to your e-bike.
1.2. Safety instructions
Instructions Pertaining to a Risk of Fire, Electric Shock or Injury to Persons
⚠ WARNINGS
When using e-bikes powered by the Hyena assist system, basic precautions should always
be followed, including the following:
• To reduce the risk of injury, close supervision is necessary when the e-bike is used near
children.
• Do not put ngers or hands into any e-bike component or touch the connector terminals
with bare hands.
• Do not use the e-bike if any exible power cord or output cable is frayed, has worn insulation
or shows any other signs of damage.
• Always check the charger, cables and power cord for any damage before charging the
battery.
• Only charge the battery using an original Hyena charger.
• Do not immerse the e-bike or any e-bike component in water.

EN-GB - 3HYENA E-BIKE SYSTEMS
⚠ WARNINGS, continued.
• Do not place the e-bike or any assist system component (like the charger) near hot or
ammable objects or materials.
• The assist system parts are not intended to be used at ambient temperatures lower than
-10°C (14°F) or over temperatures of 45°C (113°F).
• Use only genuine Hyena replacement parts. If you use anything other than genuine Hyena
replacement parts, you may compromise the safety, performance or warranty of your e-bike.
• Do not modify your assist system to increase the power or maximum speed of your assist
system.
1.3. Riding safety
• Make sure you are familiar with your new e-bike before riding it on roads with multiple
vehicle lanes and pedestrian footpaths.
• Do not start on the fastest setting right away. Start on the low assist setting for your rst
few rides.
• Do not focus on the console while riding. A distracted rider increases the risk of being
involved in an accident.
• Riding with the assist system turned o󰀨 is like riding a normal, non-electric powered bicycle.
• The assist system is designed to provide riding support up to the speed limits in compliance
with local regulations (e.g. 25 km/h in the EU region and Australia, 32 km/h in New Zealand
and 20 mph in the USA/Canada region). Do not modify your assist system or t any other
equipment to increase the power or maximum speed of your assist system, this will render
the bike illegal and void the warranty.
⚠ WARNINGS
• When the assist system is switched on and an assist level is selected, the riding support
is activated as soon as you start pedalling. You should be seated on the e-bike and
engage at least one brake before starting to pedal.
• With the assist system switched on, do not put one foot on a pedal and throw the other
leg over the bicycle, as the e-bike could accelerate unexpectedly.
Failure to follow this warning may result in serious injury or death.

Your e-bike is equipped with a 250-Watt electric motor, which forms the hub of the rear wheel
and also provides the electric riding assistance.
⚠ CAUTION
Do not dismantle the hub motor. The hub motor should only be serviced by a certied
mechanic using genuine replacement parts from Hyena.
3.1. Motor safety instructions
• Do not allow the motor to su󰀨er any mechanical or physical impacts or make any internal
modications.
• The motor can operate safely in rain and other adverse weather conditions.
