E –BIKE POWER RIDE

Introduction
Dear users,
Please read carefully all the information regarding your E-LF product to ensure optimal functioning of
your e-bike. The following text containing a comprehensive description will provide you with
information on all aspects and details (including installation, setting up and general use of the display)
regarding the use of our display. This instruction document will also help you solve potential problems
and failures.
What is an electric bicycle?
Electric bicycle is a conventional bicycle with an electric drive added to assist the rider. The motor
function is actuated by pedalling, which is scanned by a special sensor installed in the pedal hub.
Therefore, you have to keep pedalling on an e-bike, the motor is there only to help you. You can set an
electric bicycle in motion also using a control button or an accelerator but only up to the maximum
permitted speed of 6 KMPH (e.g. for walk assistance). The maximum speed of an e-bike with motor
assistance is 25 KMPH, with a 10% tolerance (when this speed limit is reached, the motor switches off
and you need to pedal just like with a regular bicycle). When your battery runs out of power or your
motor is off, you can ride your electric bicycle as a conventional bike, without any resistance at all.
From the point of view of the Road Traffic Act, an electric bicycle whose features conform to European
standard EN 15194-1 is regarded as a regular bicycle, i.e. you can ride on bike trails, do not need a
driver's license and a helmet is mandatory only up to 18 years of age.

Factors influencing the range
1. Rolling resistance of the tyres. Leader Fox e-bikes are fittet with tyres with low rolling resistance and
increased resistance to puncture. It is also important that the tyres are inflated properly. Therefor, if the
tyres of your electric bicycle are underinflated, the range will decrease.
2. Weight of the electric bicycle. The lower weight of the electric bicycle, the greater the range.
3. Battery status. It depends on whether the battery was fully charged before your trip. It is also to be
expected that the higher the number of discharge cycles the battery has undergone, the smaller capacity
it has.
4. Profile and surface of the track. The higher the elevation difference and the steeper hills you negotiate
and the worse surface, the shorter the range.
5. Riding mode. It depends on which of the three riding modes you have set.
6. Continuity of riding. The more braking and acceleration, the shorter the range.
7. Air resistance. For example, it depends on whether we ride a bicycle with low frame and sitting upright
or whether we ride sporty bicycle with seat set to the same height as the handlebars.
8. Wind strength. The stronger the wind we have beck, the longer the range and vice versa.
9. Weight of the rider and load. The greater the weight, the shorter the range.
10. External temperature. The lower the temperature, the less battery capacity can be used while riding.

Basic safety recommendations
Riding safety:
While riding, pay only as much attention to the bicycle settings and display as not to jeopardize your
safety.
Before riding, check that wheels have been securely fitted in the frame and fork, since their incorrect
installation can cause serious injury.
When riding the electric bicycle, you should be fully familiar with its behaviour and control, otherwise it
could result in serious injury.
If you ride in poor visibility conditions or at night, use the lights.
Battery:
DO NOT use the battery with other devices.
DO NOT dismantle or modify the battery.
DO NOT connect positive and negative poles of the battery with a metal object.
DO NOT immerse the battery in water.
DO NOT throw battery into fire.

Charger:
DONOT dismantle or modify the charger
DO NOT use to charge other batteries.
AVOID shocks and contact with water.
DO NOT touch the charger with wet hands.
KEEP the charger away from children and animals.
DO NOT cover the charger nor place any objects on it.
DO NOT pull the cable when disconnecting the charger, ALWAYS pull the plug.
DO NOT use the charger if it is clearly damaged.
Basic maintenance and instruction guide for the use of electric bicycle:
Always remove the battery if you are going to manipulatewith the cables or replace any part of the electric
bicycle, since there is a danger of injury by electrical current.
If you feel that the electric motor or any of its parts might have gotten loose, make sure that the nuts are
properly tightened or followfurther information in the user guidebook.
The chain should be regularly cleaned by cleaning agents for this purpose. Do not use alkaline or acidic
cleaners to remove rust or dirt. These cleaners will damage the chain.
Use the battery charger only for itsintended purpose. If the charger or any of its parts is broken, do not use
it as this could cause injury.
Electric bicycle is not intended to be used by people with lowered physical, sensory or mental capacities or
people lacking experience and knowledge required to use the product.
Electric bicycle is not intended for use by children.
Do not attempt to repair the electric motor system, as this can cause its damage and malfunction.
The bicycle electric system is designed to be fully waterproof and can therefore be used even in harsh
weather conditions or in wet environment. You should, however, avoid its direct dipping in water.
Do not use high pressure water (WAP) to clean the bicycle. If water gets into the system, this can cause
damage or corrosion.
When transporting the bicycle on a vehicle in rainy or wet weather, remove the battery and store it in a
dry place.
Handle the bicycle carefully and avoid shocks.
To clean the battery and all the plastic parts of the system, use a well wrung out, damp cloth.

Battery
Battery charging and maintenance:
Charge the battery in a dry environment to avoid short-circuit damage.
Charge the battery to at least 60% of capacity once every 3 months even when the bicycle is not used.
Do not cover the battery or the charger.
Do not leave the battery constantly connected to the power source.
Use the charger only to charge the battery.
Do not use the battery for other appliances. It has been made specifically for this model.
Do not disassemble or modify the battery pack.
Do not throw the battery into fire or expose it to extreme temperatures.
Recharging time from zero to 100 % is 4-6 hours.
If the battery is not charged after 6 hours, disconnect the battery and abort charging. The battery may
overheat, crack or ignite.
In case of liquid from battery getting into your eyes or in contact with your skin, flush with clean water
immediately and seek medical help. Otherwise, this can result in serious injury.
Do not use the battery if it is clearly damaged, it can result in its destruction.
Do not attempt to deform or otherwise tamper with the battery.
Do not attempt to solder a direct connection of battery and cables, it could result in cracks or ignition of
the battery.
Do not use the battery near fire or source of direct heat, do not throw the battery into fire, as this can
cause cracks or ignition of the battery.
Do not expose the battery to shocks or vibration.
Do not insert metal objects into the power outlet, as this could cause short-circuit, overheating, crack or
ignition of the battery.
KEEP the charger away from children and animals.
Charging:
The battery is the most expensive part of an electric bicycle; therefore, pay increased attention during
handling, charging and storage. The battery is sensitive to precise charging. Therefore, it is necessary to
charge Li-Ion rechargeable batteries using only a charger supplied by us. Connect the charger to 220-240 V
power outlet. 5A protected circuit is sufficient. The charger will automatically suspend charging when full
capacity of all cells is reached.
We recommend discharging the battery in full after each ride to ensure that your battery will be up to its
full capacity for your next ride. Charging the battery may last 1 to 5 hours depending on the condition of
the battery cells. Charge it exclusively in covered dry areas (moisture and dripping water can damage the
charger) at a temperature of 5 to 40°C.
The charging process is indicated by a red glowing LED. It will turn green when the battery is charged and
the charging process is complete. The battery contains a charge-monitoring indicator (when the charge
indicator button is pressed, the light indicator will come on). Always switch off the battery when finished
riding the bike.
Normal battery behaviour:
If the motor stops running smoothly and switches to intermittent operation, it could be a sign of low
battery capacity. In that case switch off the electric drive system and continue without motor assistance,

as if riding a conventional bicycle.
Battery warming is normal and does not indicate any defect. The battery is protected by a temperature
sensor and switches off automatically in case of excessive overheating. Wait until the battery cools down
to its normal operating temperature and then ride on.
If you feel your total battery capacity has dropped, it could be caused by charging or operation in
suboptimal climatic conditions. Carry out 3 full charging cycles. Fully discharge the battery while riding and
then charge to its full capacity at room temperature.
If the charge indicator shows that the battery is discharged, there is still a minimum voltage level in it
which protects it against damage but is not enough to power the electric bicycle. Recharge the battery as
soon as possible. Never leave the battery fully discharged, it could results in its damage.
Proper care of the battery prolongs its life.
