Assembly Instructions
Front Wheel Installation
CAUTION: Your electric bike is equipped with a front disc brake. Be careful not to damage the disc,
caliper or brake pads when reinserting the disc into the caliper. Never activate a disc brakes control
lever unless the disc is correctly inserted into the caliper.
1. Carefully take your bike out of the carton and gently rest it in place with the kickstand down as
in Figure 1.1
2. Remove all of the inside cardboard protection and bubble wrap on the ebike
3. Locate and set aside the kit box containing the battery charger pedals, tool kit, etc.
4. Remove the rubber pad and metal block from the front wheel and front fork (Figure 1.2)
5. The fork is curved, please make sure the concave of the fork is facing forward (Figure 1.3)

7
6. With the steering fork facing forward, insert the front wheel between the fork blades so that the
axle seats firmly at the top of the fork dropouts (Figure 1.4)
7. Push the wheel firmly to the top of the slots in the fork dropouts, and at the same time centring
the wheel rim in the fork
8. With a cam action system, move the cam lever upwards and swing it into the closed position
(Figure 1.5). The lever should now be parallel to the fork blade and curved toward the front
wheel. To apply enough clamping force, you should have to wrap your fingers around the fork
blade for leverage, and the lever should leave a clear imprint in the palm of your hand
PLEASE NOTE: If on a traditional camp action system, the lever cannot be pushed all the way to a
position parallel to the fork blade, return the lever to the open position. Turn the tension adjusting nut
counter-clockwise one-quarter turn and try tightening the lever again.
WARNING: Securely clamping the wheel with a cam action retention device takes considerable force. If
you can fully close the cam lever without wrapping your fingers around the fork blade for leverage, and
the lever does not leave a clear imprint in the palm of your hand, and the serrations on the wheel
fastener does not emboss the surfaces of the dropouts, the tension is insufficient. Open the lever; turn
the tension adjusting nut clockwise one-quarter turn and try again. Spin the wheel to make sure that it is
centred in the frame and clears the brake pads, then squeeze the brake lever and make sure that the
brakes are operating correctly.

Handlebar, Display and Front Reflector Installation
1. Loosen the bolt on top of the stem, then rotate the stem through 90 degrees (Figure 2.1).
2. Unscrew the four screws in front of the stem with a 5 mm hexagonal spanner, place the
handlebar on the stem, tighten the four screws slightly, and position the handlebar to your
desired comfort level, then tighten the four bolts in turn until fully tightened (Figure 2.2).
PLEASE NOTE: Before installing the handlebar, please pay attention to the wire harness that connects
to it. Make sure that the wire harness is are not twined together (Figure 2.3).
3. Once the handlebars are aligned and the top bolt is slightly secured, tighten the two side bolts
on the stem with a 6 mm hexagonal spanner firmly (Figure 2.4). After tightening the two side
bolts, tighten the top bolt with 5 mm hexagonal spanner firmly (Figure 2.5). After all three bolts
have been securely fastened, make sure there is no play in the headset.
4. Unscrew the two screws on the display, then install the display on the centre of the handlebar
(Figure 2.6).
5. Unscrew the bolt on the front of the fork, then install the front reflector.
Installation instructions can be found on YouTube at www.youtube.com/watch?v=AdTEu5iVJZA
WARNING: Do not overtighten the stem bolt. Overtightening the stem bolt can damage the steering
system and cause loss of control.

Seat Post Installation
1. Please pay attention to the vertical lines on the seat post, it is the minimum insert line or safety
line, please make sure the post is installed into the frame deeper than the minimum insertion
line. It is at the bottom of the seat post (Figure 3.1).
2. Unclamp the clamp on the seat tube, insert the seat post into the seat tube, adjusting the seat
to a comfortable height, tighten the tension adjusting nut, then press the clamp lever inwards
toward the seat tube (Figure 3.2).
PLEASE NOTE: If necessary, tighten the clamp by twisting the clamp handle clockwise while in the
unclamped position. Then, fold the handle in toward the seat post. This should require a fair amount of
force to ensure the seat post is held tightly. If necessary, the clamp can be further tightened with a
5 mm Allen wrench while in the clamped position.

10
Pedals Installation
1. Identify left versus right pedal
There is a letter L or R stamped into the axle (threaded part that looks like a screw) as in
Figure 4.1. There may also be labels on the pedals themselves. Please note they are not the
same. Apply a small amount of white grease if possible.
2. Install the left side pedal first
You will have to screw it in counter-clockwise because the threading is the reverse of a normal
screw. Do this by slowly pedalling the crank backwards. If the pedal feels stiff, stop and then
retry. It should feel like a smooth motion. Do not use a wrench until you are ready to tighten it
for the final few turns. Tighten it down until you can’t anymore (Figure 4.2).
PLEASE NOTE: Hand tightened is not sufficient. Use a wrench. Please ensure that your pedals are
properly tightened before your first ride. If after riding, the threads on your crank are stripped. You have
not followed these instructions. Your crank needs to be replaced and this would not be covered by the
warranty.
3. Install the right-side pedal
This pedal threads in clockwise, like a normal screw. Follow the same principle as discussed in
Step 2 for the left pedal (Figure 4.3).
4. Wipe off any excess grease from around the crank.

Battery Installation, Removal and Charging
1. Battery installation
Turn the key (normally the keys are tied on the clamp of the seat tube) to unlock position
(Figure 5.1). Line up the grooves on the battery and battery holder (Figure 5.2), then slide the
battery down, turn the key to lock position (Figure 5.3) and remove the key.
PLEASE NOTE: The function of the lock is to secure the battery in place on the frame only. It is not an
ignition style key system but more of an anti-theft lock mechanism for the battery.
2. Battery removal
Do the same thing as when you were installing the battery but in reverse order.
3. Battery charging
Find the charging port on the battery (Figure 5.4). Connect the charger's plug to the battery
charging port, then connect the other side plug to the AC 110 volt outlet. The LED on the charger
is red while charging. It will turn to green when the battery is fully charged. It will take six to
eight hours to fully charge the battery. Remember to fully charge the battery before your first
ride. This is very important.
PLEASE NOTE: there is a small button on the battery. Press and hold the small button to see the
remaining battery capacity through a set of red and green lights. It will show one red and three green
lights when fully charged (Figure 5.5).

12
Testing the Ebike
1. Powering up the display
Turn the key to the lock position and make sure the battery is locked firmly on the frame. Press
the M button on the handlebar and hold 3 seconds (Figure 6.1). The display unit will light up.
2. Testing the throttle, pedal assist, and walk assist modes
The ebike has three modes: throttle, pedal assist, and walk assist. Please lift the rear wheel up,
and test each mode separately as follows.
PLEASE NOTE: Make sure that the number of the PAS (pedal assist) level is 1 or higher (Figure 6.2). A
PAS level of 0 means that there will be no throttle or pedal assist power provided by the motor.
a. Throttle: Twist the throttle. It is on the right side of the handlebar (Figure 6.3).
b. Pedal assist:Lift up the rear wheel and turn the pedals by hand by three-quarters to one
full turn. The motor will engage once you turn the crank three quarter cycle (Figure 6.4).
Stop pedalling and the power assist will stop.
c. Walk assist: Press the down arrow button on the handlebar, the ebike will go into PAS
mode (Figure 6.5).

13
3. Testing the brake system
Hold the two brake levers on both sides of the handlebar, then try to push the ebike forward to
make sure the ebike is assembled firmly, and brakes can stop the ebike properly. You can adjust
the tightness of the brakes cable lightly by adjusting the knobs on the caliper (Figure 6.6).
4. Serial numbers
The ebike’s serial number is typically located near the crank as in Figure 6.7. The battery serial
number is shown on Figure 6.8. This information can be useful if your bike is ever stolen or
missing.
5. Let’s go!
You are now ready to go for a ride!

Troubleshooting
The following are some assistance tips for identifying and resolving electrical problems.
The Display Does Not Power Up
Make sure you fully charge the battery for six to eight hours before your first-time use. The LED's on
the charger should be green when the battery is fully charged.
If your display still does not turn on, please check the wires and the battery, please make sure the
connections are not loose and that the battery is installed in place and fully engaged into the locking
mechanism. Press the M button and hold it for three seconds.
If it is still not working, you will need to get a voltmeter, and do some testing.
1. Turn on the power button, then test the battery output voltage (Figure 7.1).
If the voltage is 0, it means there is something wrong with the battery output plug, cell or fuse,
please take a picture or make a video to show your test results, then send it to us.
If the battery voltage is not zero but less than 32 volts, please fully charge the battery for six to
eight hours, then test again. If the battery voltage is between 32 and 42 volts, but the display
cannot power up, it means that the battery is good. Next, we should test the other two plugs.
2. Open the controller box, and find the power wire (it is black and red) that connect the battery
and the controller (Figure 7.2).
Test the voltage of the power wire, if it is 0, it means the power wire needs to be replaced.
Please take a picture, send the photo to us. If the voltage is the same as the battery, it means
the power wires are good, and we now need to test the output voltage of the controller which is
the plug that connects the controller and display. It has five wires on the plug.
3. Test the red and black wires (Figure 7.3).
If the voltage is 0, it means the controller needs to be replaced, if the voltage is the same as the battery,
it means that the display needs to be replaced, please take some photos and send them to us.
Following the steps noted here will go a long way in helping us solve your issue in a timely manner.

17
The Throttle Does Not Work
This situation applies if the display powers up and there is no error code, and the PAS level is not set to 0
but the throttle does not work. If the number for the PAS system is 0, it means no throttle or no pedal
assistance will be provided.
You can test the PAS mode by lifting up the rear wheel and then turning the crank one whole cycle. This
is a job that should be performed by two people. You can also test the power walk assist mode by
pressing the down button and holding for three seconds.
The brakes on ebikes have two functions when you press the brake lever. One, it will stop the ebike.
Two, it will cut power off to the motor. If the electronic system sees either of the brakes as being
engaged, the power to the motor will be cut and neither throttle nor pedal power assist will be
provided.
To check for brake power cut off issues, make sure that the brake lever can be held or released with
ease. If not, maybe the brake is cutting the power to the motor. Please take a video of your test and
send it to us. We will look to determine how best to proceed.
If PAS is not set to 0 and brakes seem free and not caught or seized in any way the next thing to look at
would be wiring and connections. Find the plug on motor wire (Figure 8.1). It is possible that the
connection has become loose. Try to replug it and then restart the ebike. If all wires are intact and all
connections secure the next thing to look at would be the brake sensor. Open the controller box
(Figure 8.2). Find the two plugs that connect the brake levers and controllers. It is the only two plugs
that have two wires on each plug (Figure 8.3). Please disconnect them, then test all three modes again,
if they work, it means the brake sensor is defective and the brake wires need to be replaced. If still not
working, it likely means that the controller needs to be replaced, please video your issue and your
testing, and send the video to us.
