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 electric bicycle 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.

Battery
Battery charging and maintenance:
Charge the battery in a dry enviroment to avoid short-circuit damage.
Charge the battery to at least 60% of the 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.
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 1-7 hours.
Drive warranty:
The warranty applies to those drive parts that are not sensitive to improper handling (pack, electronics,
charger, etc.); such parts are covered by a 24-month warranty.
The warranty does not apply to chemical parts of the battery and to capacity reduction due to normal use
(39% after the expiry of two years); those parts are covered by a 12-month warranty.
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).
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.
In the case, that the battery will be turned on more than 30 min and bike will not be used, the battery will be
automatically switched off.
Battery si fully shutdown after 48h. After that time period you have to first activate the batter by switch
button or connect battery with charger.
Proper care of the battery prolongs its life.
