GEAR OPERATION
Multi speed bicycles can have internal or derailleur gear systems.
WARNING: Improper shifting can result in the chain jamming,
or becoming derailed resulting in loss of control or a crash.
Always be sure the chain is fully engaged in the desired gear
before pedaling hard.
Avoid shifting while standing up on the pedals or under load.
To shift properly, pedal the bicycle with little pressure on the pedals, and
move the shifter (1) gear at a time, ensuring that the chain is fully engaged
in that gear before applying more pressure on the pedals. For bicycles with 3
front chain rings; avoid “Cross Chaining”, which is the position when the chain
is in the smallest cog in the rear combined with the inner or smallest chain
ring in the front, or the largest cog in the rear and the outer or largest chain
ring in the front. These gear positions put the chain at the most extreme angle
and can cause premature wear to the drivetrain. Bicycles with 3 front chain
rings have enough gear “overlaps” that these gears are not needed.

Internal Gears (no derailleur)
An internal gear system is one where the gears are housed within the rear hub of the
bicycle. With internally geared bicycles, it is recommended to STOP pedaling while you
shift gears. The bike may be sitting still or rolling to shift. Shifter designs vary, you will
either twist or operate a push button to change gears. The shifter will indicate either
“low to “high” or a series of numbers from 1 up. Low or “1” is the lowest gear. This is
used for slower riding, hill climbing, or to allow for easier pedaling. It is recommended
to start off in this gear and move through the gears as speed increases as needed,
or comfortable. It is OK to ride the whole time in only one gear if this is comfortable.
Backpedaling should have no effect on an internally geared bicycle (unless it is equipped
with foot activated brakes), however, backpedaling should not be necessary when
riding, and invites the possibility of clothing being caught in the chain, and should
be avoided. See Assembly and Maintenance for further information on proper
gear adjustment. (Fig. 2.14)
