One of such hobbies is cycling. Due to a rise in interest in casual cycling in the form of a hobby rather than the pursuit of professional aspirations, cases of related accidents have also been on the rise. Contact accidents are one of the most common types of such accidents. On the other hand, a number of new Internet of Things (IoT) products that combine objects with the internet have been introduced. In line with these trends, this study aims to design and realize a bike backview capable of allowing cyclists to view blindspots in real time. An Arduino was used and a Raspberry Pi was used for the purpose of providing a real-time streaming display. Due to the fact that a bike backview provides to cyclists visual and audible means of checking blindspots in real-time that are otherwise difficult to visually check, it is expected to prevent the occurrence of contact accidents associated with bikes.
