ABSTRACT:
An aerodynamic bicycle that reduces intra-abdominal pressure, improves aerodynamic performance, and improves muscular power efficiency includes various structures to support and hold the driver in a lying down, prone position, rather than in a sitting position. The bicycle includes: (a) a front wheel; (b) a rear wheel; (c) a frame connected to the front wheel and the rear wheel; (d) a handlebar for controlling a direction of travel of the bicycle; (e) a seat member supporting a gluteus region of the bicycle driver; (f) a first support member for supporting hips of the driver; (g) a second support member for supporting an axillary or sternal region of the driver; (h) a first, smaller sprocket located at the hub of the rear wheel; (i) a pedal unit including two pedals and a second sprocket located proximate to a circumference of the rear wheel; and (j) a chain connecting the first sprocket and the second sprocket. A top surface of the seat member on which the gluteus region of the driver is supported is arranged at an angle between vertical and horizontal such that the gluteus region of the driver is supported against gravitational forces without placing the driver in a sitting position. A seat guide movably holds the seat member such that it can be adjusted to different heights. The seat member is removably fastened to the seat guide such that these two elements can be rapidly unfastened in the event that the bicycle driver falls.
