Radar electronic rearview mirror system for bicycles

A radar electronic rearview mirror system applicable to a bicycle, the bicycle comprising a front adjacent to a front wheel and a rear adjacent to a rear wheel, the radar electronic rearview mirror system comprising:

• an environment sensing module, disposed at the rear of the bicycle to capture an environment information from a rear side of the bicycle and to output an environment sensing signal;
• a display module, disposed at the front of the bicycle and electrically connected to the environment sensing module to receive the environment sensing signal, wherein the display module comprises a screen, and the screen is configured to display an image corresponding to the environment sensing signal;
• and
• a light sensing module, disposed on the bicycle with a sensing surface of the light sensing module facing upward, wherein the light sensing module is electrically connected to the environment sensing module and/or the display module;
• wherein the environment sensing module and/or the display module is adapted to be operated in a normal mode or a night mode, and the environment sensing module and/or the display module is configured to switch between the normal mode and the night mode according to a light intensity sensing signal outputted from the light sensing module.
