An electronic component for an electric bicycle, the electric bicycle including a transmission, the electronic component comprising:
- a processor configured to:
- determine a condition of the electric bicycle;
- identify an existence of a transmission loss of the transmission of the electric bicycle;
- and
- control an assist motor of the electric bicycle based on the identified existence of the transmission loss and the determined condition of the electric bicycle
- wherein the processor being configured to identify the existence of the transmission loss comprises the processor being configured to:
- determine a speed of an output of a clutch of the electric bicycle;
- determine a speed of an input to the clutch of the electric bicycle;
- determine a difference between the speed of the output of the clutch and the speed of the input of the clutch;
- and
- the processor being configured to control the assist motor of the electric bicycle based on the identified existence of the transmission loss and the determined condition of the electric bicycle comprises the processor being configured to control a speed of the assist motor of the electric bicycle based on the determined difference.
