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 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
