The oldest and simplest type of bicycle is the "fixed-gear" bicycle. This is a single-speed bike without a freewheel; that is, whenever the bike is in motion, the pedals will go around. You cannot coast on a fixed-gear machine.There is an almost mystical connection between a fixed-gear cyclist and bicycle, it feels like an extension of your body to a greater extent than does a freewheel-equipped machine.
