E –BIKE POWER RIDE

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.

Maintenance
Regular maintenance:
- maintain all components of the electric bicycle clean
- use only the recommended and tested cleaning materials
- regularly lubricate the chain with suitable oils
- in winter, clean the electric bicycle after each ride and pay increased attention to removing salt fromm
battery contacts and other connectors
- while handling the electric bicycle, make sure the cables of the electric system are not damaged.
Damaged cables pose a risk of electricshock
- regularly check all connections for correct tightening and brakes for correct function. Check also
individual parts of the electric bicycle for damage. For example: cracks on the frame, fork, handlebars,
stem, damage to cables, damage to battery pack, etc.
- always remove the battery before transporting the electric bicycle on or in a car
Battery transport:
Battery transport is subject to the requirements of regulations on dangerous goods. Private users may
transport undamaged batteries on roads without having to conform to other conditions.
In case of transport by commercial users or by third parties it is necessary to comply with special packaging
and marking requirements (e.g. ADR regulations)
Batteries should only be sent if the battery pack is undamaged. Plug loose contacts and pack the battery to
prevent its movement in the packaging. Notify the forwarding service that the transport concerns
dangerous goods.
Battery storage:
Store the battery in a dry and well-ventilated place, out of reach of direct sunlight and other heat sources.
In case of cold storage it is necessary to let the battery warm up to normal room temperature (20°C)
before putting into operation.
Never leave the battery fully discharged. It could result in its permanentdamage. For long-term storage
keep the battery fully charged. However, do not store it while permanently connected to the charger or
installed in the electric bicycle.
Li-Ion batteries are fully recyclable. After expiry of the battery life you can returnit at any collection point
or your dealer.
If you use an e-bike in hard conditions (long-term use of the maximum assistance), for longer ride at higher
temperatures (30 ° C or above), in direct sunlight or when the battery is partially discharged and a
combination of these situations is it possible that bike will automaticly swith off. This is a fuse protecting
the control unit against burning. We recommend stop the ride and let the bike (control unit) cool down
little bit. This is not a defect.

Possible problems and their solutions
In case of system failure perform its diagnostics or contact your dealer.
The control LCD display is not on:
- always make sure the battery is charged
- check whether the battery is inserted correctly, whether the battery switch is on
- check the connections of the control unit and the display
The motor does not start when the walk assistance button is pressed
- check the connection of the motor cable (at the motor and the control unit)
- check the connections of the control unit and the display
The motor does not start when rotating the pedal cranks (pedalling)
- check the connection of the pedalling sensor to the control unit
- check the distance between the pedalling sensor and the magnet disk (max. 4 mm)
- check whether the disk is firmly attached to the central axle and does not spin freely
- in case of use of compact-type pedalling sensor

Warning
When there is a problem with the electric bicycle, it can show error messages. LCD display will show the

Assembly and disassembly of the wheel with the engine
For transportation and maintenance (replacing the tire tube) it may sometimes be necessary to
disassemble the wheel with the engine.
First, pull lightly to disconnect the engine connector (about 20 cm from the engine entry).
Then loosen the brake (if it is used) and change the gear to the smallest wheel.
Remove the rubber covers from the wheel nuts.
Loosen the engine nut using a spanner size 18 and remove the wheel from the frame.
For assembly, reverse the order of these steps.
To connect the connector properly, the arrows on the connector (1) must face each other.
Switch the drive unit on and test it.
During wheel assembly, pay attention to the proper position of the central axis of the wheel nave facing
down. The cable must enter the engine from below. Otherwise, water could get into the engine on the
cable and the engine could be damaged.
