SHIFTER/DERAILLEUR
SHIFTER
This E-bike is equipped with gears, that include:
• A rear sprocket cluster called a freewheel or cog set
• A rear derailleur
• One shifter
• One control cable
• One front sprocket
• A drive chain
There are many different types of shifter mechanisms, each preferred for specific
applications because of their ergonomic, performance and price characteristics.
A downshift is a shift to a lower or slower gear, which makes it easier to pedal.
An up-shift is a shift to a higher or faster gear, which makes it harder to pedal.
For example, you can downshift to a lower gear to make pedalling easier on a hill.
On the other hand, you may up-shift to a higher gear when you wish to go faster.
Whether up-shifting or downshifting, the derailleur system requires that the drive chain
is moving forward and is under at least some tension. A derailleur will shift only if you are
pedalling forward.
CAUTION: NEVER MOVE THE SHIFTER WHILE PEDALLING BACKWARD.
DO NOT PEDAL BACKWARDS AFTER MOVING THE SHIFTER. EITHER OF THESE
ACTIONS COULD JAM THE CHAIN AND CAUSE SEVERE
DAMAGE TO THE E-BIKE.
Shift the rear shifter to the highest number indicated,
loosen the cable from the rear derailleur cable anchor
bolt, and place the chain on the smallest sprocket.
Adjust the high limit screw so that the guide pulley
and the smallest sprocket line up vertically.
Re-tighten the cable, pull out any slack and re-tighten
the anchor bolt securely. When shifting through the
gears, make sure that each gear changes quietly and
without hesitation. It is necessary to use the barrel
adjuster to fine-tune the cable tension by turning it in
the direction you want the chain to go. For example,
turning clockwise will loosen the cable tension and
move the chain away from the wheel, while turning
counter-clockwise will tighten cable tension and
direct the chain to the wheel.

PEDAL ASSIST & THROTTLES
This E-Bike has an electric pedal-assisted driving system (PAS).The pedal-assisted driving
system consists of a driving unit, a battery, a controller, and various electronic compo-
nents (harness wires, sensors and switches). It is essential to know that when the pedal
assist system is on, the driving unit provides power only while you are pedalling. The
amount of power supplied by the unit depends on your pedalling force and the assis-
tance model/level you set with the handlebar control unit at any time. When you stop
pedalling, the pedal assist system will disengage. In all models/levels, the pedal-assisted
driving system reduces progressively. It cuts off as the bike reaches 25KM/h (15.5MPH),
or sooner if you stop pedalling. The pedal-assisted driving system re-engages when
speed drops below 25KM/H (15.5MPH) as long the pedals are turning.
PEDAL INSTALLATION
The RIDEAU & COLUMBUS are equipped with a thumb
throttle. The more you press down on the throttle,
the faster the motor system will propel the bicycle.
DO NOT USE PEDAL ASSIST AND THE THUMB THROTTLE AT THE
SAME TIME.
The AURORA is equipped with a twist grip throttle.
The more you twist the throttle, the faster the motor
system will propel the bicycle.
DO NOT USE PEDAL ASSIST AND THE TWIST GRIP THROTTLE AT
THE SAME TIME.
Pedals are a pair with “R” & “L” (Picture 1): “R” for right, “L” for left.
Tighten the pedals in the direction of the threads.

DERAILLEUR
The derailleur system includes the front and rear
derailleur, the shift levers, and the derailleur control
cables, all of which must function correctly for smooth
gear shifting to occur. The front and rear derailleurs
are adjusted in the factory. You will need to
inspect and adjust both before riding your E-Bike.
