INSTALLATION AND ADJUSTMENT
2.1 Handlebar and Stem Assembly
1. Open the top cover, align the stem with the head tube and slide it on. Tighten the screw at the top of the stem.
2. Align the handlebar to be perpendicular to the wheel, then insert and tighten the two side-facing screws as shown below.
3. Move the handlebar up or down to adjust to the desired angle, then tighten the rear-facing screw at the top of the stem to lock the handlebar in place.
4. Close the cover to complete installation and adjustment.
INSTALLATION AND ADJUSTMENT
2.2 Assembly of the Pedals– Identify your pedals: check the letters on the pedals, “L” or “R”.– The “R” marked pedal is for the right (when facing the forward direction). For attachment to the crank, tighten clockwise.– The “L” marked pedal is for the left. For attachment, tighten counterclockwise when facing directly.
WARNING:First screw on the pedals by hand, then tighten with the wrench provided.
2.3 Seat Position
To enable comfortable, fatigue-free, and safe riding, the saddle and handlebar height should be adjusted to the body size of the rider.
The saddle height is correct if the leg is near full extension while the foot is resting flat on the pedal in the bottom position of the crank cycle. The toes must still be able to touch the ground comfortably.
2.4 Saddle HeightThe quick-release lever must require noticeable effort to put into fully closed position to prevent any undesired movement while riding.
WARNING:An improperly closed quick release lever can open again or have limited ability to keep the saddle in place. This may cause the saddle to suddenly drop into the seat tube, potentially leading to serious falls and injury.
There is a minimum insertion line marked on the seat post (failure to observe the minimum insertion line can result in serious injury); please ensure the seat post is always inserted into the seat tube beyond this line (the line must be inside the seat tube).-Loosen the quick-release lever at the top of the seat tube, determine the appropriate saddle height and tighten the clamp. -The clamping force can be adjusted by adjusting the bolt on the quick-release lever.-The quick-release lever must be closed with considerable counter pressure.
2.5 Saddle Adjustment
The saddle can also be tilted and adjusted in the forward/back direction.– Loosen the bolt at the bottom (4).– Adjust the saddle tilt by pressing down on the front or rear of the saddle– Move the saddle forward or backward to adjust for arm/torso length and desired to ride position.– Tighten the bolt (4) to secure the saddle.

4.2 NORMAL OPERATION
FULL VIEW AREA
NORMAL VIEW AREAWith the display on, the default indicators are riding mode, trip 2, speed, PAS level, and battery indicator as shown in the figure below.Press SET to change the display information.
Section 1: ON/OFFPress ON/OFF to activate the display. With the display on, press ON/OFF for 2 seconds to turn off power. With the display off, there is no battery power consumption.The panel will power off automatically when speed is 0 mph for 5 minutes.
Section 2: CURRENT INDICATORThe current indicator shows the present discharging current of the controller: each segment is 2A, six segments are ≥ 12A.(The bar graph shows the power output of the motor in real time. 1 bar indicates low power, full bars maximum power.)
Section 3:3.1 BACKLIGHTPress ON/OFF to turn on the backlight. Press it again to turn off the backlight.
3.2 SPEED INDICATORThe central area displays the current riding speed of the E-bike. The speed display is as below.
3.3 KM/H and MPHSelecting KM/H or MPH for the speed and mileage will switch all indicators to the selected unit of measurement.
Section 4: OPERATION4.1 PAS LEVEL SELECTIONPress UP (+) or DOWN (-) to change the PAS level and thus change the power output of the motor. The default mode isPAS 1 and assistance ranges from level 0 to level 6. Level 0 provides no assistance from the motor.
4.2 ERROR CODE INDICATORIf there is something wrong with the electronic control system, the display will flash at 1Hz and show the error code automatically. Different error codes represent different faults in the system, consult the error code table on the last page for details(4.3).
The display cannot return to normal status until the problem is solved, the E-bike’s electric components will not operate if there is an error in the system. However, the bike can still be operated conventionally (without electric assistance).Hold ON/OFF and SET at the same time to show the error code.
4.3 WALK MODEHold DOWN (-) for 2 seconds to enter the power-assisted walk mode. When the 6KM icon is lit, the E-bike will travel at 3.7 mph without the need for the rider to pedal. Assisted walk mode will end when the DOWN (-) button is no longer being held.
4.4 SET OPERATION
4.4.1 KM/H and MPHHold UP (+) for 8 seconds to enter the unit of speed selection mode, then press UP (+) or DOWN (-) to switch between KM/H and MPH and press SET to confirm and exit.

Recommendations and Maintenance
5.1 General RequirementsE-bikes use metal shells to cover the electric components, so we strongly advise against the use of excessive water to wash the shells and parts around them. Use a soft cloth with a neutral solution to wipe the dirt off the shells. Afterward, wipe everything dry with a clean soft cloth.
Do not use high-pressure water or air hoses for cleaning; this can force water into electrical components, which may cause malfunctioning.
Do not wash plastic components with excessive water. When the internal electrical parts are affected by water the insulator may corrode, leading to power drain or other problems.
Do not use soap solutions to wash the metal components. Non-neutral solutions may cause discoloration, distortion,scratching, etc.
Avoid leaving the bike outdoorsWhen not riding, keep the bike in a location where it will be protected from snow, rain, sun, etc. Snow and rain can cause the bike to corrode. ultraviolet rays from the sun can cause unnecessary fading of paint or crack any rubber or plastic on the bike.

WARNING:—As with all mechanical components, electrically power-assisted cycles (EPAC) are subjected to wear and high stresses. Different materials and components may react to wear or stress fatigue in different ways. If the design life of a component has been exceeded, it may suddenly fail, possibly causing injuries to the rider. Any form of crack, scratches or change of coloring in highly stressed areas indicates that the life of the component has been reached and it should be replaced.

A poorly installed or modified component can increase the stress on all other parts, greatly increasing their chance of failure. Modifications can also adversely affect the handling of your bike, resulting in loss of control, falls and serious injury. Please do not add, remove, or modify parts of your bike in any way before consulting with a trained bike technician. We recommend you consult with us at before you make modifications or add parts, in order to confirm their safety and compatibility with your bike.
