What is Electric Bicycle?
Electric bicycle is a standard bicycle with added electrical motor which provides pedal assist. The motor is
activated by pedalling which is only helping you. Electric bicycle can be also set in motion by the control
button or the accelerator but only up to the maximum speed limit, i.e. 6km/h. (e.g. while walking with your
bike). The maximum speed for motor power assist is 25km/h with the tolerance of 10% (when you reach
this speed, the motor switches itself off and you pedal as you would riding a conventional bicycle). When
your battery runs ou tor if the motor is switched off, you can ride the electric bicycle the same way as a
conventional bicycle.
The properties of the electric bicycle conform to the European Standart EN 15194-1 and the electric bicycle
is in terms of Road Traffic Law viewed as a conventional bicycle i.e., you can ride in bicycle lanes, you do
not need a driving license and the use of helmet is compulsory only until the age of 18.

Factors influencing the electric bicycle range
1. Rolling friction of tires. LEADER FOX e-bikes are fitted with tires with low rolling resistence and increased
resistence to puncture. It is also important that the tires are inflated properly. Therefor, if the tires of your
electric bicycle are underinflated, the range will decrease.
2. Weight of the electric bicycle. The lower the 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 highr the number of discharge cycles the battery has undergone, the smaller capacity it
has.
4. Route profile and surface. The range is shorter, the bigger the altitude difference, the poorer the surface
and the steeper slopes you climb.
5. Mode of riding. It depends on which riding (assistance) mode you have set.
6. Continuity of riding. The more braking and acceleration, the shorter the range.
7. Air resistence. Air resistence levels depend on whether we ride a bicycle with a low frame and sitting
upriht or whether we ride a sporty bicycles with seat set to the same height as the handlebars.
8. Wind speed. The stronger the wind we have in the back, the longer the range and vice versa.
9. Weight of the rider and load. The greater the weight, the shorter the mileage.
10. External temperature. The lower the external temperature, the lower the capacity.

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.

Basic maintenance and instruction guide for the use of electric bicycle:
Always remove the battery if you are going to manipulate with 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 follow further 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 its intended 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.
Electric set:
The system uses monitoring of torque, monitoring of speed of the pedal assist system and monitoring of
real speed of wheels.
The system uses a dual protection feedback for measuring the speed signal to ensure safety and reliability
of the system.

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.

Use the battery only in this temperature range:
Operation: -10°C - 50°C
Charging: 0°C - 40°C
Charging:
Please pay close attention to handling, charging and storage of the battery, as battery is the most
expensive part of the electric bicycle. The battery is sensitive to precise charging. Therefore, it is necessary
to charge Li-Ion rechargeable batteries using the charger supplied. Connect the charger to 220-240V power
outlet. 5A protected circuit is sufficient. The charger will automatically suspend charging when full capacity
of all cells is reached.
It is recommended to fully charge the battery after every ride. Battery charging can take 1 to 5 hours
depending on the condition of the battery cells. Charging should only be performed in indoor dry areas
(wet conditions and dripping water can damage the charger) at the temperatures of 5 to 40°C.
The charging process is indicated by red glowing LED. After the battery is charged and the charging process
is finished, green LED will light up. The battery contains a charge-monitoring indicator (when the charge
indicator button is pressed, the charge indicator will light up). If the LED on the charger turns green
immediately after the battery is connected, it is possible that the charger or the battery is faulty. Repeat
the charging process and if this does not change, please contact your seller.
Always switch off the battery when finished riding the bike.
Normal battery behaviour:
If the motor stops running smoothly and starts being “jerky”, it can indicate that battery is too low. In this
case, turn off the electric power system and continue without motor assistance as you would when riding a
conventional bicycle.
The battery may heat up and this 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 the normal operating temperature and then ride on.
If you feel that the total capacity of the battery has decreased, this could happen due to charging or
operation in non-ideal weather conditions. Perform 3 full charging cycles. Fully discharge the battery
during riding and then charge it to full capacity in room temperature.
If the status indicator shows that the battery is discharged, there is still minimal voltage left, which protects
the battery from damage but is not sufficient to power the electric bicycle. Charge the battery as soon as
possible. Never leave the battery in fully discharged state as this could result in damage.
