Whether upshifting or downshifting the E-Bike™, the
derailleur system requires that the drive chain be moving
forward and be under at least some tension. A derailleur will
shift only if you are pedaling forward.
CAUTION:
Never move the shifter while pedaling backward, nor pedal
backwards after having moved the shifter. This could jam the
chain and cause serious damage to the E-Bike™.
WARNING:
Never shift a misadjusted derailleur onto the largest or the
smallest sprocket. The chain could jam, causing you to lose
control and fall.
Derailleur Adjustment
The function of the rear derailleur is to move the drive chain
from one gear to another on the rear gear cluster, thereby
changing gear drive ratio. The smaller sprockets on the gear
cluster produce higher gear ratios. Pedaling in the higher
gears requires greater pedaling effort, but takes you a greater
distance with each revolution of the pedal crank. The larger
sprockets produce lower gear ratios. Using them requires
less pedaling effort, but takes you a shorter distance with
each pedal crank revolution.
Moving the chain from a smaller sprocket of the gear cluster
to a larger sprocket results in a downshift. Moving the chain
from a larger sprocket to a smaller sprocket results in an
upshift. In order for the derailleur to disengage the chain from
one sprocket and move it on to another, the chain must be
moving forward (i.e. the rider must be pedaling forward).
Three screws, the H-, L-, and B-screws, are used to adjust
the derailleur. The H-screw sets the outward limit of the
derailleur’s movement. The L-screw sets its inward limit. The
B-screw adjusts the distance between the bottom of the
cogset and the derailleur’s guide pulley.
A fourth–hand tool (Park Tool BT-2) is required to perform this
procedure.
1. Check the cable attachment to the derailleur pinch
mechanism.
a. Inspect the position of the inner wire in the pinch-
mechanism. The inner wire should follow the groove
