12.Instructions for using Front derailleur:
12.1 When you shift forward the left derailleur handle, the front derailleur will
move outward, at the same time, move the chain from the small part of the
chain ring to the large part. These steps will increase the riding speed while
riding, also will increase the pedaling strength of riding. When shift backward
the derailleur handle bar, the front derailleur moves from outside to inside, at
the same time, move the chain from the large part of the chain ring to the
small part. These steps will reduce the riding speed while riding, also will
reduce the pedaling strength of riding. So as to realize the different speed of
the front derailleur.
12.2 When you shift forward the right derailleur handle, the back derailleur
will move inside, at the same time, move the chain from the small part of the
rear flywheel to the large part. These steps will reduce the riding speed while
riding, also will reduce the pedaling strength of riding. When the handle bar at
the maximum position(as shown in picture 3 below), press the accelerator
button on the right derailleur handle, the back derailleur will move outward, at
the same time, move the chain from the large part of the rear flywheel to the
small part. These steps will increase the riding speed while riding, also will
increase the pedaling strength of riding.So as to realize the different speed of
the back derailleur.
