A bicycle that is too big or too small for riding is difficult to control and may be
uncomfortable.
Size of the frame (one inch = 25,4mm):
To check if the size of the bicycle is correct, just get on it and put your hands on
the handlebars. If your crotch touches the frame, the bicycle is too big for you.
