How can I check the charging status of my ebike battery?

When the battery is in the ebike, you can see the charge level of the battery in the handlebar display: One LED stands for 20% capacity. 5 LEDs mean that your bike is 100% charged.

If you have removed the battery, you can find out the charge level by pressing the small rubber button on the metal side of the battery. Then one of the following colors will light up:

Blue = 66% - 100% charge
Yellow = 32% - 66% charge
Red = 0% - 32% charge
