A large number of people drive electric bicycles faster and faster because of something or excitement, but if they encounter an electronic speedometer, they can let the traffic police know how fast you are driving.

The speed of electric bicycle licensing

Measure the speed with a speedometer. According to the different distances measured by different instruments, the commonly used speedometers are mainly divided into radar speedometers and laser speedometers. Compared with the effective distance of radar velocimeter, the measuring distance of laser velocimeter is 1000 meters. The distance between the measured object and the test point can be determined by emitting a laser beam to the measured object, receiving the reflected wave of the laser beam and recording the time difference.

When the speed radar finds a vehicle speeding, it will immediately start the camera program, take high-precision photos of the vehicle suspected of speeding, and record that the license plate of the vehicle has the driver's characteristics. The traffic police will immediately inform the police waiting in front to intercept the suspected vehicle and transmit the evidence of the suspected vehicle speeding to the inspection point.
