Getting Started
1. Assembling: 1) Open the box, take out your eBike, and remove
the packaging. 2) Mount the front wheel to the front fork, and
tighten the screws to lock into place. 3) Assemble and align the
handlebar upon the riser, and lock into place. 4) Walk the eBike to
ensure no abnormal sound from the turning wheels. Gently pull
the brake levers for a couple of times to ensure both the front and
rear brakes function normally. 5) Adjust the seat tube to desired
height, and lock the quick release. 6) Install the pedals and tighten
up. (Please wear a helmet when riding the eBike.)
2. Charging: Connect the DC jack of the original charger to the
charging slot of your eBike, and the AC plug to the mains. The
charger light turns from red to green when charging is complete.
(When the battery does not need charging, do not keep the AC
plug connected to the mains and do not keep the charger con-
nected to the battery. Do not charge indoors. When charging out-
doors, avoid rain or direct sun on the charger.)
3. Power on and off: Locate the power button on the left handle.
Press it to power on, and to power off, press and hold it for three
seconds. The eBike automatically powers off upon ten minutes of
inactivity
4.Display: The display in the center of the handlebar shows battery
level, speed, mode, lights, and failure report.
5. Shifting mode (motor speed): Locate the M button on the left
handle. When the power is on, press it to shift the motor speed.
Mode E/D/S corresponds to the motor-powered maximum speed
of 15 km/h (or 9.32 mph), 25 km/h (or 15.53 mph) and 32 km/h
(19.88 mph).
6. Headlight: After turning on the eBike, press the light button
located left of handlebar.

7. Cruise control: When the desired uniform riding speed is
reached, maintain the position of the throttle for eight seconds to
start cruising. Releasing the throttle would not affect the cruising
speed. Twist the throttle again to accelerate, or pull the brake
levers to stop cruising.
8. Riding modes:
a. Sports Mode: Power is off and there is no motor output. Pedal
and exercise.
b. Throttle Mode: When the power is on, twist the throttle to accel-
erate and start the ride without pedaling.
c. Pedal Assist Mode: When the power is on and while you are ped-
aling, the motor also provides power for an easier and more ener-
gy-efficient ride.
9.Power cut-off brakes: When you pull the brake levers, the con-
troller cuts off the motor output. The mechanical disc brakes are
also engaged. As long as the brake levers are not completely
released, Pedal Assist Mode or Throttle Mode remains disabled.
10. Removing and installing the battery: This battery is removable.
To remove it, open the battery lock, and the upper part of the bat-
tery pops up. Take out the battery in the upward direction. To
install the battery, start with the bottom of the battery and slide it
down through the battery tube. Make sure the discharge port is
connected well with the plug of the connector. Push in the upper
part, clip it in to the battery tube, and lock the battery. (For battery
replacement upon damage, please contact our official customer
service.)

Installing the Front Wheel
I. Basic mechanical principle with the quick release lever
Turn the adjusting nut clockwise to increase clamping, and anti-clockwise to
decrease.
For the quick release lever to be in the CLOSE position, turn the adjusting nut clock-
wise. As the nut screws inwards, the wheel is clamped onto the frame and locked
into the correct position.
II. How to install
1. Open the quick release lever, and insert the front wheel all the way into the drop-
outs of the front fork.
2. With your left hand, turn the adjusting nut clockwise to fasten up, and with your
right hand, close the quick lease lever. Continue to turn the adjusting nut till the
lever runs parallel to the hub (as indicated below) and resistance from the lever is
felt.
3. Hold the legs of the front fork with your fingers, and use your palm to press on the
quick release lever to lock into place. The CLOSE mark should face outwards, and
the lever should be ahead of the legs or parallel to them (as indicated below).

Gears
Some KORNORGE eBikes come with gears, which consists of:
• Rear sprocket cluster, called freewheel or cog set
• Rear derailleur
• Shifter
• Control cable
• Front sprocket, called chaining
• Drive chain
The gear mechanism differs in ergonomic design, performance and
price.
A downshift is a shift to a lower or slower gear, which makes pedaling
easier. An upshift is a shift to a higher or faster gear, which makes
pedaling harder. In practice, you can upshift to go faster, and you can
downshift to go uphill.
A shift is possible only when you are pedaling forward, i.e. the drive
chain is moving forward and under some tension.
CAUTION
Never shift when pedaling backward. Also, do not pedal backwards
after a shift. Either action may jam the chain and cause serious
damage to your eBike.

Derailleur System
The derailleur system includes front and rear derailleurs, shift levers,
and derailleur control cables. For smooth shifting, all components
must function properly.
Although the front and rear derailleurs are initially adjusted in the
factory, you need to inspect them before each ride.
To begin, twist the shifter to the largest number indicated, and the
cable shall loosen the anchor bolt on the rear derailleur, placing the
chain on the smallest sprocket. Adjust the high limit screw so that
the guide pulley and the smallest sprocket are lined up vertically.
Re-tighten the cable, pull out any slack, and re-tighten the anchor
bolt securely. Shifting through the gears, making sure that each gear
is achieved quietly and swiftly.
If necessary, use the barrel adjuster to fine tune the cable tension by
turning it the direction you want the chain to go. For example,
turning clockwise loosens cable tension and moves the chain away
from the wheel, while turning counter-clockwise tightens cable
tension and direct the chain towards the wheel.

speed of 15 to 20 km/h (or 9.32 to 12.43 mph), on smooth and firm terrain, with a load of 120
kg (or 264.55 lbs.), and within an uninterrupted period from full to zero battery level. The
ranges may vary, depending on your riding behavior, ambient temperature, load, tire
pressure, terrain, etc.
