5.3 Select assistance level on handlebar panel
When the power is on, you can shift to 3 assistance levels, Low, Middle and High. Press the button MODE to
shift the assistance level (Low, middle, and high). Here below the way how to set the assistance level: When
nd
the power is on, the "middle" LED is on, which means the power-assistance is in the 2
grade. Then you can
press the MODE button to choose the Low, Middle and High.
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, windy day or heavy load riding.
When shifting to middle assistance level, it means electric and human propulsion almost fifty/fifty applied to
this bike. We suggest you select this assistance level, when riding in 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.
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 you 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 protect it from damage, please use and maintain it according to the
guideline below:
