ABSTRACT:
A "Unique" bicycle is basically a bicycle having three bottom bracket shells namely, a first bottom bracket shell (70) for the crankset (57), located at the down tube (40), a second bottom bracket shell (72) for the first converter (FIG. 6) located at the bottom end of the seat tube (42), and a third bottom bracket shell (74) for the second converter (FIG. 7), located at about the middle of the seat tube (42).
Three separate chains are used to interconnect all the gears. The first chain (62) connects the chainwheel (58) to the first converter's small gear (22) and its large gear (24) is connected to the second converter's small gear (22) by means of the second chain (62), while the large gear (24) is connected to the rear wheel gear (64) by means of the third chain (62).
The "Unique" bicycle has a slightly longer top tube (36) and its down tube (40) is also longer but is bent horizontally at the lower portion in order to position the crankset (57) farther away from the saddle (48) so as to provide a comfortable, erect, sitting position for the rider similar to that of a motorcycle.
The converters make it possible to easily pick up speed and less tiring to maintain top speeds for prolonged periods of time.
