---|---|---|---
1. Open the battery lock.| 2.The upper part of
the battery pops up.| 3. Take out the battery
as the arrow above
indicates.| Screw in the right pedal clockwise,
and the left counter-clockwise.
Getting Started
- 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.)
- 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 connected to the battery. Do not charge indoors. When charging outdoors, avoid rain or direct sun on the charger.)
- 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
- Display: The display in the center of the handlebar shows battery level, speed, mode, lights, and failure report.
- 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).
- Headlight: After turning on the eBike, press the light button located left of handlebar.
- 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.
- 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 accelerate and start the ride without pedaling. c. Pedal Assist Mode: When the power is on and while you are pedaling, the motor also provides power for an easier and more energy-efficient ride.
- Power cut-off brakes: When you pull the brake levers, the controller 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.
- Removing and installing the battery: This battery is removable. To remove it, open the battery lock, and the upper part of the battery 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 clockwise. As the nut screws inwards, the wheel is clamped onto the frame
and locked into the correct position.
II. How to install
-
Open the quick release lever, and insert the front wheel all the way into the dropouts of the front fork.
-
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.
-
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.
