Having a rearview camera in your car can be quite useful. It could give you more confidence when you put your car in the reverse gear to move backwards. The Bicycle Rearview Camera is not designed for that purpose. It is mainly for those who want to see what’s going on behind them when they are on their bike. It mounts to a bicycle’s seat post to provide you with 75 degree field of view of what’s behind you. The Bicycle Rearview Camera makes your riding experience safer. It will cost you $179.95 though.
