Problems solved by technology

In the operation of shared bicycles, because they are different from traditional bicycles, shared bicycles cannot be brought into the home, and must be placed in public areas such as the street, which leads to the fact that shared bicycles will be wet when it rains. It is not about the user's use; on the other hand, the shared bicycle is exposed to the sun in the open air on a hot day, causing the seat to become hot, and the user will feel extremely uncomfortable when using it.
