✓ When selecting the HIGH assistance level, meaning more electric power and less human propulsion are
applied to the bike.
✓ This level is suitable for uphill, head wind or heavy load riding.
✓ When shifting to MID assistance level, it means electric and human propulsion almost fifty/fifty applied to this
bike. We suggest you select this assistance level, when riding a regular flat paved road.
✓ When shifting to LOW assistance level, it means less electric and more human propulsion being applied to the
bike. Therefore, this is an electric saving level (or economical level). We suggest you select this level when you
ride this bike for leisure sports or fitness.
✓ Acting on the "+" and "-" buttons, it is possible to use three intermediate assistance levels, which can be
activated when, passing from the predefined LOW, MID and HIGH levels, the LEDs will start to flash.
✓ Moreover, this power display function can also alert users through these four LED lights, as shown below:
✓ If the user forgets to turn off the battery switch after five minutes of stopping the ride, the lights of the four
LED will turn one after another. In this way to remind the user to turn off the power immediately to save
energy.
Warning: Please turn off the main switch on the battery, if yo stop riding the bike. This is very important for
saving the electric energy, stored in the battery.
6. Using and maintaining the battery
Advantages of Li-ion battery. This electric assistance bicycles are supplied with high quality Li-ion batteries,
which are light and create no pollution to the environment, as a typical green energy source. As well as the
above features, the Li-ion batteries have the following advantages:
• charging without memory effect
• big electric energy capacity, small volume, light in weight, with large current output, suitable for high
power vehicles.
• long life
• a wide working range of temperature: -10°C to +40°C.
To ensure a longer battery life and protecting it from damage, please use and maintain it according to the
guideline below:
6.1 During your riding, when you find the power decreased on the
display LED (see the Fig. 6.1), the battery must be charged in short
time!
