Bicycle frames are divided into several different categories. High step or diamond frames have the top tube high up. Low step or step-through frames have the top tube low down. There are also bicycles with folding frames. Cycle frames are also divided into whether or not they have suspension. A hardtail frame is one where the rear part of the frame is rigid. A full suspension (FS) frame has suspension in the rear part of the frame.
