A bicycle can be slowed down by dragging the feet on the ground owing to frictional force.
Friction can be defined as the force acting between two surfaces in contact, which oppose the motion of one body over another.
When feet are dragged, the force acts in the opposite direction thus reducing the speed of the bicycle.
