Batteries
Battery Charging and Maintenance:
The battery is the most expensive part of an electric bike, so it is important to handle, charge, and store it with care. For Li-ion batteries, it is necessary to use only the charger supplied with the e-bike. To charge the battery, plug the charger into a 220-240V mains supply with a 5A fused circuit. The charger will automatically stop charging when all cells have reached full capacity.
The charging process is indicated by a red LED on the charger. When the battery is fully charged, the LED will light up green. The battery itself also has a charge indicator light that can be activated by pressing the charge indicator button. After riding, remember to switch off the battery.

FAQ
- Q: What factors affect the range of an electric bike?
- A: The range of an electric bike can be influenced by factors such as air resistance, wind strength, weight of the rider and load, and external temperature. Riding a low-frame bike in an upright position may result in higher air resistance and shorter range. Strong winds at your back can increase the range, while riding against strong winds can decrease it. Heavier weights and lower temperatures can also reduce the battery capacity and shorten the range.
- Q: What does the warranty cover for the drive?
- A: The warranty covers parts of the drive that are not susceptible to rough handling, such as packaging, electronics, charger, etc. These parts are covered by a 24-month warranty. However, the warranty does not cover the chemical parts of the battery or the reduction in capacity caused by normal use. The battery is covered by a warranty of 12 months.
The seller is legally obliged to include the instruction manual for the LEADER FOX electric bicycle with each product.
Foreword
Dear users,
To ensure the optimal functioning of your e-bike, please read the E-LF product information carefully before using it. By means of a conscientious description, we inform you in the following text about all details (including device installation, settings and normal use of the display) related to the use of our display. This manual will also help you to resolve any uncertainties and faults.
What is an e-bike
- An electric bicycle is a classic bicycle with an electric drive to assist in riding. The motor function is activated by pedalling, which is sensed by a special sensor located in the pedalling centre. So you have to pedal all the time on the electric bike, the motor only helps you. You can also set the e-bike in motion using the control button or the accelerator, but only up to the maximum permitted speed, i.e. 6 km/h (e.g. for walking assistance). The maximum speed of a motor-assisted e-bike is 25 km/h with a tolerance of 10 % (when you reach this speed, the motor switches off and you continue pedalling as on a normal bicycle). When the battery runs out or the motor is switched off, you can ride the e-bike like a normal bicycle without any resistance.
- An electric bicycle that complies with the European standard EN 15194-1 is treated as a normal bicycle in terms of road traffic law, i.e. you can ride on cycle paths, you do not need a driving licence and a helmet is only compulsory up to the age of 18.
Description
Electric bike range factors
-
The range of an e-bike cannot be accurately determined because it is influenced by many factors.
-
Tyre rolling resistance. LEADER FOX electric bikes use tyres with low rolling resistance and increased puncture resistance. It is also important that the tyres are properly inflated. So if you have under-inflated tyres on your e-bike, for example, your range will be reduced.
-
Weight of the electric bike. The lower the weight of the e-bike, the more range it has.
-
Battery status. It depends on whether the battery was fully charged before the ride. You should also take into account that the higher the number of discharge cycles the battery has had, the lower its capacity.
Profile and surface of the route. The higher the elevation, the worse the surface and the steeper the hills, the shorter the range. -
Driving mode. It depends on which of the driving modes you have set when driving
-
Air resistance. It depends if you are riding a low-frame bike in an upright position or if you are riding a sportier bike and have the saddle set at the same height as the handlebars.
-
Wind strength. The stronger the wind at our backs, the longer the range and vice versa.
-
Weight of rider and load. The greater the weight, the shorter the range.
-
External temperature The lower the temperature, the lower the battery capacity.
-
Safety recommendations
Batteries:
Do not throw the battery into the fire. Do not use the battery with other
devices. Do not disassemble or modify the battery.
Do not connect the positive and negative poles of the battery with a metal
object. Do not immerse the battery
in water.
The charger:
Do not disassemble or modify the charger Do not use to charge other batteries. Avoid impact and contact with water. Do not touch the charger with wet hands. Keep the charger out of reach of children and pets. Do not cover the charger or place other things on top of it. When disconnecting the charger, do not pull the cable but the plug. Do not use the charger if it is obviously damaged.
Batteries
Battery charging and maintenance :
Charge the battery in a dry environment to prevent damage from short circuits.
Charge the battery at least once every 3 months, even when the bike is not in
use, to at least 60 % capacity. Do not cover the battery or the charger. Do
not leave the battery connected to electricity at all times.
Do not use the battery for other appliances. It is made specifically for this
model. Do not disassemble or modify the battery case.
Do not throw into fire or expose to extreme temperatures. The time to charge
the battery from zero to 100 % is 1-5 hours.
Warranty for the drive:
The warranty covers those parts of the drive that are not susceptible to rough
handling (packaging, electronics, charger, etc.), these parts are covered by a
24-month warranty. The warranty does not cover the chemical parts of the
battery and the reduction in capacity caused by normal use (39 % after a
period of two years), these parts are covered by a warranty of 12 months.
Charging:
The battery is the most expensive part of an electric bike, so pay extra
attention when handling, charging and storing it. The battery is sensitive to
accurate charging, so for Li-ion batteries it is necessary to use only the
harger we supply. Plug the charger into a 220240 V mains supply, a 5 A fused
circuit is sufficient. The charger itself will stop charging when all cells
have reached full capacity.
We recommend that you always fully charge the battery after each journey to
ensure that you always have a full battery capacity for your next journey.
Charging the battery can take from 1 to 5 hours depending on the state of the
battery cells.
It should be carried out in a covered, dry area (moisture and water can damage
the charger) at a temperature of 5 to 40°C. The charging process is indicated
by a red LED on the charger. When the battery is charged and the charging
process is complete, it will light up green. The battery contains a charge
indicator light (the charge indicator light comes on when the charge indicator
button is pressed).Switch off the battery after riding.
Normal battery behaviour:
If the engine stops running smoothly and starts running “jerkily”, the battery
may be too low. In this case, switch off the electric drive system and
continue without motor assistance as on a normal bicycle. Battery overheating
is a common occurrence and is not a fault. The battery is protected by a
temperature sensor and will automatically switch off in the event of excessive
overheating. Wait for the battery to cool down to normal operating temperature
and continue riding.
If you feel that the overall battery capacity has dropped, this could be due
to charging or operation in nonideal weather conditions. Perform 3 full
recharge cycles. Fully discharge the battery by driving and then recharge to
full capacity at room temperature.
If the status indicator shows that the battery is discharged, there is still a minimum voltage in the battery to protect it from damage, but it is not sufficient to power the e-bike. Recharge the battery as soon as possible. Never leave the battery completely discharged, as it could be damaged. If the battery has been switched on for 30 minutes and the bike is not in use, it will switch off automatically.
Proper care of the battery extends its life.

Damaged cables pose a risk of electric shock regularly check that all connections are tightened correctly and that the brakes are working. Also check individual parts of the electric bike for damage. For example: cracks on the frame, fork, handlebars, stem, damaged cables, damaged battery cover, etc. Always remove the battery before transporting the e-bike on or in the car
Transportation of the battery:
The requirements of the Dangerous Goods Regulations apply to the transport of batteries. Undamaged batteries can be transported by private users on the road without complying with other conditions. Special packaging and labelling requirements (e.g. ADR regulations) must be observed when transported by commercial users or third parties. Only ship batteries if they do not have a damaged cover. Seal loose contacts and pack the battery so that it does not move in the packaging. Notify the delivery service that this is dangerous goods.
Battery storage:
- Store the battery in a dry and ventilated place out of direct sunlight and other heat sources. In case of cold storage, the battery must first be allowed to warm up to normal room temperature (20 °C) before being put into operation.
Never leave the battery fully discharged. It could be permanently damaged. Keep the battery fully charged during long-term storage. However, do not store it permanently connected to the charger or placed in the electric bike.
Li-ion batteries are fully recyclable. At the end of the battery’s life, you can dispose of it at any collection point or at your dealer. If the bike is used under heavy loads (prolonged use of maximum assistance), for extended periods of riding in hot temperatures (30 °C or more), in direct sunlight, or with a partially discharged battery, and a combination of these situations, the e-bike may shut down. This is a fuse to protect the control unit from burning. The bike should be allowed to cool down for a while and then you can continue riding. This is not a defect.
