Shift System
Operation
There are two shift levers on the bicycle. The
Operate the shift system as follows:
-The rider turns the rear shift control around the handlebar (for twistshift models) or moves the shift lever (thumbshift models) to an index position
-When the rear shift control moves into each position with a “click” sound, the shift is complete
-The rider turns the front shift control around the handlebar (for twistshift models) or moves the shift lever to an index position (thumbshift models)
-Each shift control pulls a cable wire that is attached to the derailleur
-The derailleur moves and guides the chain from one sprocket to another
-If there is some chain noise after the shift, turn the rear shift control a small amount to “trim” the rear derailleur.
CAUTION: Do not force the shift levers. Shift only when pedaling forward and without 
strong force. Do not backpedal. Backpedaling can cause the chain to come off the
sprockets. Backpedaling and shifting while not pedaling can damage the sprockets and stretch the cable wire.
There is no “correct gear” in which to ride the bicycle. The “correct gear” is the one that is comfortable to you. To select a gear or sprocket combination while riding:
-While pedaling, shift the chain onto different front and rear sprocket combinations
-You will feel a difference in the rhythm and ease of pedaling
-Shift the chain to the gear that allows you to pedal at a rhythm and effort that is comfortable to you
-When riding uphill or against the wind, you may wish to keep the chain on the smallest front sprocket [1] and shift the chain on the rear sprocket cluster [2]
-These are the lower gear combinations
