Electric Assisted Bike Regulations
The EN 15194 EU standard or EPAC (Electric Power Assisted Cycle) conforms to the following
characteristics for electric power assisted bikes:
• Motor assistance only starts when the cyclist pedals.
• The assistance cuts out as soon as the cyclist stops pedalling.
• The assistance cuts out as soon as the speed exceeds 25km/h.
Adherence to this standard enables the use of the electric bikes in the same conditions as
any other bicycle, particularly on bicycle paths and bicycle-specific lanes.
Recommendation before First Ride
1. Before first use, double-check the function of all the parts of your electric bike. If you
have any doubts or if you detect a problem, contact Kogan.com for further support
assistance.
2. If you lend your bicycle to a third party, give them this user guide with the bicycle
and ensure that they read it before the first ride.
3. Respect local, state and national road traffic regulations.
4. For your safety, it is highly recommended that you wear a certified helmet. Ensure
you are always following local helmet laws while operating the bicycle.
5. When used during heavy rain, snow, in slippery conditions or in the case of low
visibility, be careful and adjust your speed.
6. At night, ensure the bicycle headlights are activated while operating.
7. Tr y i n g t o r e p a i r a n y t h i n g t h a t involves removing technical or electrical components
is strongly advised against. If maintenance or repair is necessary, contact
Kogan.com for support assistance.
8. The manufacturer declines any responsibility due to overloading or items that are
not correctly attached to the baggage rack.
9. Using high pressured water jets to clean the bike is strongly advised against.
10. Check the battery level before each use. Ensure the battery is fully charged prior to
first use.
11. In order to extend battery performance and lifespan, do not commence operation
when the battery is only half-charged.
12. The battery life will vary depending on where you ride it (inclines will reduce power
rapidly) and how you ride (assistance mode chosen). The greater the assistance
used, the more you'll use the battery and the shorter it will last. This bike is fitted
with gears; remember to use them accordingly relative to riding conditions in order
to extend battery life. The amount of weight carried will also have an impact on
battery lifespan. Extreme low temperatures can also impact battery lifespan.
13. It is recommended that you charge the battery at least every 2 months when the
bike is not used; during winter, for example.
SAFETY & WARNINGS

14. Store the battery in a dry place after having completely recharged it. Avoid extreme
temperatures (both low and high) as they can damage the battery. Optimal
operating range: -10°C to 35°C.
Cleaning and Maintenance
• Use a damp cloth with neutral detergent to clean the bike frame. Do not use any
detergents or cleaning liquids liable to deteriorate the frame or components.
• Use a dedicated bicycle cleaner or hot soapy water to clean your bike and its
components, such as wheels, hubs, rims, brakes and pedals. Rinse well with clean
water before use.
• Do not use high pressure water jets to clean your bike, especially on the electrical
components (such as the battery), as this may result in short circuiting or system
malfunctions.
• All the components and parts of your bicycle are subject to normal wear and fatigue.
• Keep a close eye on any change in the shape or colour of a component or traces of
oxidation (rust) on your bicycle. If this occurs, do not use the product until the
component has been replaced.
Warning
• Do not ride after consuming alcohol or drugs (prescribed or not), or while under the
affects of medication which might make you drowsy.
• Do not ride while you feel unwell, nor after consuming alcohol or drugs. This product has
the potential to endanger yourself and others if not operated responsibly.
• Pedal-assisted bicycles are not designed for 2 or more people. Do not ride carry
passengers as these bicycles are not designed to carry the additional load of a second
rider.
• Do not put batteries in normal waste bins. Dispose of used batteries in a certified
recycling facility.
• Do not over-lubricate; if oil contacts the wheel rim, brake pads or brake disks, this will
result in loss of braking performance and an increase in stopping distances. This could
potentially cause loss of control, accidents, and injury.
Transport
It is highly recommended that you do not overload your pedal-assisted bicycle, as this may
damage the electrical components or cause malfunctions, such as overheating of the
battery or the motor. Do not store the battery in excessively hot or cold places.
• Maximum transport weight on the bicycle must not exceed 75kg.
• Regularly check battery brackets and mountings.
• Always wear a helmet when riding your pedal-assisted bicycle.
• If a rack is not already fitted to your bicycle, please do not attempt to fit one yourself.
