1. 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 (includ-
ing installation, setting up and general use of the display) regarding the use of our display. This instructions document
will also help you to solve potential problems and failures.
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.
the 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 a low frame and sitting upright or whether
we ride a sporty bicycle with the seat set to the same height as the handlebars.
8.Wind strength. 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 range.
10.External temperature. The lower the temperature, the less battery capacity can be used while riding.

Battery charging and maintenance:
Charge the battery in a dry environment 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.
Use the charger only to charge the battery.
Do not dismantle or modify the battery case.
Recharging time from zero to 100 % is 4-5 hours.
Drive warranty:
Battery – 2-year warranty.The warranty does not cover the common loss of
battery capacity caused by its use (39 % after 2-year period).
Charging: The battery is sensitive to precise charging. Therefore, it is necessary to charge Li-Ion rechargeable batteries
only with the charger supplied along with the batteries.
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 to ensure
that the battery will be at full capacity and ready for the next trip. Charging may take
1 to 5 hours depending on the condition of the battery cells. Always charge the battery in dry, roofed (e.g. indoors)
premises
(as moisture and running water may damage the charger) at temperatures from 5 to 40 °C.
and the process is terminated, the LED will be glowing green.
The battery contains a charge-monitoring indicator (when the charge indicator button is pressed, the
light charge indicator will turn on).

Safety recommendations:
Battery
DO NOT use the battery with other devices.

Error code meaning
The 800U meter will display the respective warning if a failure of the e-bike occurs. The display will show the error icon
with error code 1 to 7. The meaning of the individual error codes can be found in the table below.
Warning:
In case of incorrect gear shifting (use of "heavy" gears when riding up), the control unit may overheat under extreme
conditions. This is normal and does not indicate any defect. The control unit is protected by a temperature sensor and
switches off automatically in case of excessive overheating. Wait until it cools down to the operating temperature and
then ride on.

Warning
There is a watertight membrane inside the sound port. Do not insert any sharp objects into the port as they may damage
the watertight membrane. The meter may display high temperatures when exposed to the direct sunlight – this is not a
meter defect.

Change of electric bicycle inner tube
Nr.4
Nr.1
Nr.2
Nr.3
Before you start changing an electric bicycle inner tube, switch off the drive unit / battery and disconnect the motor
lead-in cable connector (1). After the connector has been disconnected by pulling it slightly, remove the rubber covers
(2) from the wheel nuts. Loosen the nuts (3) using a spanner of a size of 18 mm. Take the wheel out and change the
inner tube in the same way as with a standard bike. After the change is completed, tighten the nuts (3) and connect the
connector. To connect the connector properly, the arrows on the connector must face each other (4). Switch on the drive
unit and test its functioning.
* Maximum endurance distances cannot be guaranteed.

If you do not understand any of the points in this instructions manual, please contact the seller for explanation. Please
read the whole manual, it is not too long.
Do not lend the e-bike to persons not briefed in its use and operation. Any claims/complaints based on improper opera-
tion will not be admitted.

ated by persons unable to pedal on and handle the bike on their own. The manufacturer cannot be held responsible for
any potential injuries or damage to the bike!
Ideal weather conditions for use of the e-bike are dry days with outside temperature higher than 10 °C. When operat-
ing the bike at lower temperatures, physical phenomena cause energy from the battery to be drained faster. It is NOT
recommended to operate the bike at temperatures below 0 °C.
Warning
It is forbidden to tamper with the connections of the electric motor, controller, and battery. Breach of this article
may result in the warranty not being acknowledged or in irreversible damage to the e-bike.
