Panning on two wheels

As I have explained, it is a work done on panning and on two wheels. Within the series there are two different groups. One is in color and the other is in black and white. There is a mixed group that, being either in color or in black and white, joins the mobile phone. It has its explanation. The color is because I looked for a colorful background, or in the case of the girl in the red coat and bicycle, I had the help of the lights in the window, since it was the Golden Hour and I never use flash in my photos. Always in natural light, or the one that They provide me with street lamps or street windows.
