A saddle-ride type electric vehicle includes an electric motor for generates power for rotationally driving a rear wheel. Each received data signal experiences a similar channel response. The shaft arrangement extends into the transmission. The light conversion layer is configured to convert a portion of the first light into a second light according to light emitted by the wavelength conversion particle. That is, the transmitter can be configured to prioritize sending new data over retaining previously transmitted data for support of data retransmissions.
