BICYCLE'S TRANSMISSION SYSTEM USING LESS ENERGY FIELD OF THE INVENTION
The present invention relates to a bicycle' s transmission system, and more particularly,- to a bicycle's transmission system consisting of an apparatus that can lead to the less energy required to paddle.
BACKGROUND OF THE INVENTION
Bicycle is invented by James Starley of british where in to be a personal transportation, and has a relative moderate mileage, healthy, cheap, easy to use and environment friendly. In Indonesia bicycle utility as 'Green Vehicle' or environment friendly vehicle does not need a fuel and does not produce any emissions.
As a public transportation, the bicycle should have a comfort and safety in driving. Besides, because of bicycle is running due to the foot paddling through the pedal, the bicycle should also feels easy and light in paddling. It means that design of bicycle, particularly in this case, the bicycle transmission system, should be established or designed for users energy saving in bicycle's paddling.
Conventional bicycle's transmission system generally comprises a main sprocket (front) that spinning because of connected on the pedal stroke of bicycle, through of a crank arm, a rotatable driven sprocket connected to the rear wheels and a continuous chain that is passed around on the both sprocket to transmit the driving force from pedals 's rotating to the rear wheels.
Some bicycle's transmission system using a variable transmission ratio has also been known and widely used that consisting of the main sprocket (front) and the rear sprocket, which usually consisting of two or more sprocket arrangement of different sizes connected to the rear wheels. Such transmission system can be selectively switched gears to
levels typically provide three or more different transmission ratios. Transmission systems that have been known to not provide a variable transmission ratio is limited but a limited number of transmission ratios.
Several studies have been conducted on the effects of the power transmission system bicycle pedal cyclists, such as Price and Donne has studied the amount of oxygen needs for cyclist on transmission systems bicycle existing during pedaling for some periode . They said that there are significant differences between the oxygen needs of the existing transmission systems.
Patent document from application P-950545, entitled "A Simple Energy Saving Tool For Bike", applicant is Jeeng-Neng Fan, recent developments will propose a system of technologies in the transmission cycle, i.e, an energy-saving devices for bicycles pedal through the installation of a sleeve swing ('swivel') which can rotate freely on the drive arm to move the chain wheel (sprocket) and a pedal attached to the other side of the swing arm.
Therefore, in general the bicycle transmission systems that has been known in general above systems uses transmission system by gears (sprocket single) , profit will paddle out energy savings obtained proved not maximum, because strokes are directly enabled to drive the main sprocket which further transmitted to the wheels usually have a small sprocket connected with the rear wheel of a bicycle.

DETAILED DESCRIPTION OF THE INVENTION
A Detailed description of the invention will be further described with reference to the drawings of the invention. Although in this case the description consisting of instances embodiments, other embodiments may be possible, and changes can be made to the embodiments described without departing from the scope and the scope of the present invention.
Referring to Figure 1, which shows a perspective view of a bicycle transmission system corresponding previous invention (Prior-Art), which consists of a swing arm ('swivel') (3 ') which can rotate freely on the arm propulsion (2') to drive the chain wheel (sprocket) {4 ') and a pedal (1') attached to the other side of the swing arm (3 ').
Furthermore, bicycle's transmission system according to the present invention will be described in detail with reference from Figure 2 to Figure 5. Bicycle's transmission system according to the present invention basically consisting of two main parts, which is a part of the power input and the power output section. The power input covering of a bicycle's crank shaft (1), connected, in use, the pedals (2) of the bicycle through the intermediary of a crank arm (3); and a spiral spring (4) attached to one of the long side of the crankshaft (1) in that operations the spiral spring (4) can be played directly by the torque of the pedal paddle (2) by
the crankshaft (1) . A section of power output covering of a main sprocket (5) connected in parallel in direct contact with the spiral spring (4) that be paired parallel to the crankshaft (1) between the crank arm (3) and spiral spring (4); a second sprocket (6) smaller than the- main sprocket (5) mounted can rotated by interconnection between main sprocket gear and second sprocket gear (5), in order to obtain a more rotation, and a next sprocket (7) paired attached directly to the second sprocket (6), wherein the rotation of a second sprocket ( 6 ) caused by the rotation of a main sprocket (5) will be directly lead to the rotation of the next sprocket (7), where the rotation of the next sprocket (7) can be transmitted to drive the motion of a bicycle chain.
