Factors Influencing Electric Bicycle Range

Several factors can influence the range of the electric bicycle, including terrain, rider weight, riding style, and battery capacity.

Safety Instructions

• Battery Switch and LED Indication: The battery switch allows you to turn the electric bicycle on and off. LED indicators on the battery provide information about the charging status.
• Charging Set: The charging set includes a charger for the battery.

Battery Charging and Maintenance

The battery is a sensitive component and requires proper handling, charging, and storage. Only use the charger provided by LEADER FOX to charge the Li-Ion rechargeable battery. Connect the charger to a 220-240V power outlet with a 5A-protected circuit. The charger will automatically stop charging when the battery is fully charged.

During the charging process, a red LED indicates that the battery is being charged. When the battery is fully charged, the LED turns green. The battery also has a charge-monitoring indicator that can be activated by pressing the charge indicator button.

Normal Battery Behavior

If the motor starts running intermittently, it may indicate low battery capacity. In such cases, switch off the electric drive system and continue riding without motor assistance.

Battery warming is normal and does not indicate a defect. The battery is equipped with a temperature sensor and will automatically turn off in case of excessive overheating. Wait for the battery to cool down to its normal operating temperature before riding again.

If you notice a decrease in total battery capacity, it could be due to charging or operating in suboptimal climatic conditions. Perform three full charging cycles by fully discharging the battery while riding and then charging it to its full capacity at room temperature.

Even if the charge indicator shows that the battery is discharged, there is still a minimum voltage level remaining.

Drive Warranty

The warranty covers drive parts that are not sensitive to improper handling, such as the pack, electronics, and charger, for 24 months. However, chemical parts of the battery and capacity reduction due to normal use are only covered for 12 months.

Introduction

Dear users,
Please read carefully all the information regarding your E-LF product to ensure the 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?

An 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.

Description

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. Therefore, if the tyres 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 higher the number of discharge cycles the battery has undergone, the smaller the capacity it has.
4. Profile and surface of the track. The higher the elevation difference and the steeper hills you negotiate and the worse 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 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.

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 itProper care of the battery prolongs its life.

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 from battery contacts and other connectors
• while handling the electric bicycle, making 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 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.

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 it into operation. Never leave the battery fully discharged. It could result in its permanent damage. 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 the expiry of the battery life, you can return it at any collection point or dealer. If you use an e-bike in hard conditions (long-term use of the maximum assistance), for a 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 automatically switch off. This is a fuse protecting the control unit against burning. We recommend stop the ride and let the bike (control unit) cool down a 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 and whether the battery switch is on
• check the connections between 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 the 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 icon and an error code will be displayed on the speed display. See their meaning in the table below

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.
