Leader Fox Electric Bicycle Operating Instructions
Model: Swan
Introduction
Dear users, Please read carefully all the information regarding your E-LF product to ensure optimal functioning of your e-bike. This document provides a comprehensive description covering all aspects and details, including installation, setting up, and general use of the display. It 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 to assist the rider. The motor is activated by pedaling, detected by a special sensor in the pedal hub. You must continue pedaling for the motor to assist. An electric bicycle can also be set in motion using a control button or accelerator, but only up to a maximum permitted speed of 6 KMPH (e.g., for walk assistance). The maximum speed with motor assistance is 25 KMPH, with a 10% tolerance. When this speed limit is reached, the motor switches off, and you pedal like a regular bicycle. If the battery runs out or the motor is off, the electric bicycle can be ridden as a conventional bike without resistance.
According to the Road Traffic Act, an electric bicycle conforming to European standard EN 15194-1 is considered a regular bicycle. This means you can ride on bike trails, do not need a driver's license, and a helmet is mandatory only for riders up to 18 years of age.

Factors influencing the electric bicycle range
- Rolling resistance of the tyres: Leader Fox e-bikes are fitted with tyres offering low rolling resistance and increased puncture resistance. Proper tyre inflation is crucial; underinflated tyres will decrease the range.
- Weight of the electric bicycle: A lighter electric bicycle offers a greater range.
- Battery status: Range depends on whether the battery was fully charged before the trip. Higher numbers of discharge cycles may result in smaller battery capacity.
- Profile and surface of the track: Higher elevation differences, steeper hills, and rougher surfaces will shorten the range.
- Riding mode: The selected riding mode (among three options) affects the range.
- Continuity of riding: Frequent braking and acceleration reduce the range.
- Air resistance: Riding posture affects air resistance; a sporty position with the seat at handlebar height creates less resistance than an upright position with a low frame.
- Wind strength: Riding with a headwind reduces range, while a tailwind increases it.
- Weight of the rider and load: Greater weight leads to a shorter range.
- External temperature: Lower temperatures reduce the usable battery capacity while riding.

Battery
Battery Charging and Maintenance
- Charge the battery in a dry environment to prevent short-circuit damage.
- Charge the battery to at least 60% capacity every 3 months, even when not in use.
- Do not cover the battery or charger.
- Do not leave the battery constantly connected to the power source.
- Do not use the battery for other appliances; it is model-specific.
- Do not disassemble or modify the battery pack.
- Do not throw the battery into fire or expose it to extreme temperatures.
- Recharging time from 0% to 100% is 1-7 hours.
Drive Warranty
- Drive parts not sensitive to improper handling (pack, electronics, charger) are covered by a 24-month warranty.
- Battery chemical parts and capacity reduction due to normal use (up to 39% after two years) are covered by a 12-month warranty.
Charging
The battery is the most expensive component. Handle, charge, and store it with care. Li-Ion batteries require precise charging using the supplied charger connected to a 220-240V outlet. A 5A protected circuit is sufficient. The charger automatically suspends charging when full capacity is reached.
It is recommended to fully discharge the battery after each ride for optimal next-ride capacity. Charging may take 1 to 5 hours depending on battery cell condition. Charge only in covered, dry areas (moisture can damage the charger) at temperatures between 5°C and 40°C.
The charging process is indicated by a red LED, turning green upon completion. The battery has a charge-monitoring indicator. Always switch off the battery when finished riding.
Normal Battery Behaviour
If the motor operates intermittently, it may indicate low battery capacity. Switch off the electric drive system and continue riding without motor assistance.
Battery warming is normal. The battery is protected by a temperature sensor and will switch off automatically if it overheats. Allow it to cool down before riding.
A perceived drop in total battery capacity might be due to charging or operation in suboptimal climatic conditions. Perform 3 full charging cycles: fully discharge while riding, then charge to full capacity at room temperature.
If the charge indicator shows the battery is discharged, a minimum voltage level remains to protect against damage but is insufficient to power the bicycle. Recharge the battery promptly. Never leave the battery fully discharged, as this can cause damage.
If the battery is turned on for over 30 minutes without the bike being used, it will automatically switch off.
Proper care of the battery prolongs its life.
