Problems solved by technology

[0002] In the hot summer weather, the backs of people in cars are scorched by the sun, which causes the backs to be hot, resulting in a decrease in comfort. At the same time, bicycles rely on human power to walk. Long-distance driving itself is very tiring. In summer, cyclists feel even more sweltering heat, and such difficult conditions are currently insurmountable
