Some of the most common aches and pains is knee cap pain, which that can be adjusted by increasing the seat height and moving the seat forward and back depending on the angle of your knees then. Most people have their seats too low and that creates more pressure in the knee cap. Another common one is low back pain, which would be a combination of changing the seat and the handlebars so that they're not leaning too far forward. Another one would be numbness and tingling in the hands, which usually is they're leaning too far forward up on the handlebars, so it needs to be a combination of changing the seat and the handlebars so that they're not putting too much weight into their hands and causing the numbness and tingling then.
