Abstract
A bicycle frame for a tall bike and a tall bike using the frame are disclosed. The frame includes an upwardly-tilted quadrilateral front frame portion, and a triangular rear portion sharing a common seat tube with the quadrilateral frame portion. The seat tube defines the forward leg of the rear triangle and the rearmost leg of the quadrilateral, and most or all of the seat tube is located forwardly of a radially forward-most point of a rear wheel mounted to the rear of the triangular frame portion. A crankset is mounted on an upper part of the seat tube below the top tube and above the down tube, also vertically forward of the rear wheel. The frame provides improved balance and stability and strength for a tall bike.
