An accident determination system that determines an occurrence of an accident in a straddle-type vehicle, includes a stop detection unit, an end operation unit and a weight detection unit, a control unit. The stop detection unit detects a vehicle stop of the straddle-type vehicle. The end operation unit receives a driving end operation performed by an occupant. The weight detection unit detects a weight value according to a posture of the occupant. The control unit determines whether the vehicle stop is caused by dismounting based on a detection result of the stop detection unit and an operation result of the end operation unit, and determines an occurrence of an accident based on a detection result of the weight detection unit during the vehicle stop caused by a reason other than dismounting.

A bicycle power meter includes a strain gauge, a signal processing unit, a processor, and a signal transmitter. The strain gauge is disposed on at least one of an outer peripheral wall and an inner peripheral wall of a stem of a bicycle. The signal processing unit connected to the strain gauge by signal correspondingly outputs an electrical signal based on a deformation of the stem detected by the strain gauge. The processor connected to the signal processing unit by signal receives the electrical signal sent by the signal processing unit and calculates a measuring value based on the electrical signal and sends the measuring value in an output signal. The signal transmitter connected to the processor by signal receives the output signal sent by the processor and converts the output signal to a wired or wireless signal and sends the wired or wireless signal to a terminal device.
