The operating ZBike's LED changes colour depending on the work mode it is in.
When it is connected to the power supply and is not paired to any device, the LED will be green.
If the ZBike is paired with any device through ANT+ communication, the LED will turn white.
If a Bluetooth communication is used instead, the LED will turn blue.
If the LED is red, this is because the ZBike's electronics have detected a malfunction and it is recommended to contact Zycle to help you.
