Assembling

Read all of the instructions carefully. Be familiar with the proper operation of all items.
This quick guide is intended to list the steps needed to assemble your bike with some mechanical skills. It is not a complete manual or training. If you do not feel comfortable or lack some of the skills to assemble it yourself, reach out to a cyclist friend, a local bike mechanic or one of our support technicians for guidance.
Our QA mechanics have assembled and tested your bike beforehand.
To assemble your bike, work on a clean area with enough space to maneuver.
If installed, remove the battery from the bike to start the assembly.
Inspect the bike completely to be sure no damage occurred during shipping.
The kickstand is designed to support the bicycle only. Not the rider mounted.
You can adjust your saddle position and the tilt on your handlebar items for comfort.
Check all screws and parts are tight and properly fixed. We recommend a pre-trip inspection before your first rides.

Installing Your Handlebars

Point the headset towards the front of the bike.
Place the handlebar in the handlebar mount being careful with the wires.
Face the mounting brackets on the front end of the mount with the round edges facing outward.
Insert the screws into the screw holes and tighten alternating sides until secure (4mm allen wrench with 6NM tight torque).
Verify your front tire lines up with your headset.
Tighten screws on stem end (4mm allen wrench with 6N strength) and top of the stem (5mm allen wrench with 6-8N strength).
Check all headset items are tight.

Installing Your Front Wheel

Insert the front wheel between the front fork on the bike. Be sure to align the disk between the brake caliper as shown in Figure 2.
Now on the outside add the spacer, washer and end nut on each side and hand turn until almost tight.
Using 5mm allen wrench, tighten each side end nut putting your weight into the wrench.
The End Nut must be very tight, be sure to re-tighten after your first couple rides, its tight torque shall be 15-18NM

Installing Your Pedals

Warning: Incorrect installation will cause damage. Please read the instructions and watch our videos if needed.
Identify the Left and Right markings on the pedals. They can only be installed in their respective side.
a. L is for the Left Pedal and it goes on the Left Crank Arm.
b. R is for the Right pedal and it goes on the Right Crank Arm (Chain Side).
Sitting on your bike the pedals go on the Left and Right side respectively.
Keep the pedal Horizontal while hand screwing to get the thread started. Then Use your 15mm wrench to tighten them.
Both pedals tighten towards the front of the bike. The left pedal is reverse threaded to allow this.
The pedals need to be very tight, be sure to retighten after your first couple rides.

Installing Your Headlight

Place the headlight with its bracket in front of the fork gantry. Push the screw provided on the headlight through the installing hole on the fork gantry. Tighten the fixing nut onto the screw. (You might need to secure the fixing nut tightly so the screw doesn’t turn).
Connect the headlight cable with the wire coming out from the downtube.

Battery

To Install the Battery

Turn the key counterclockwise to release the lock.
Seat the bottom of the battery into the receptacle first and push the upper side of the battery into the frame tightly until it gets locked with a clatter sound. Seat your battery securely, turn the key clockwise to lock the battery. Remove the key from the lock before each riding.

To Remove the Battery

Turn off the LCD display.
The battery is secured with a double-lock mechanism. Use the key to release the first lock.
Keep your left hand holding the battery. Use your right hand to turn the lock switch under the downtube counterclockwise and the battery will drop off. When the lock is released, hold the battery with both hands and take it off from the bike.

Note: Please hold the battery tight with one hand at least as it will drop off when the lock is released.

Charging

Notes of Charging:

Charging time varies from 8 to 10 hours. Never charge a battery for more than 12 hours at a time.
The small LED light on the charger in RED indicates it is in charge; The small LED light on the charger in GREEN indicates it is fully charged.
Insufficient charging will not influence the battery lifecycle. AVOIDING deep discharge is helpful to protect the battery and extend its lifecycle.
If the battery will not be used for a long period, take it off from the bike and discharge its capacity to 60%-80% for stock. Disconnect it from the charger and place it in a dry, ventilated place without direct sunlight. In order to maintain a long lifecycle, it is recommended to charge the battery every two months even when it is in static without use.
Pay attention to check whether the surface temperature of the battery case rises too high during charging. It is FORBIDDEN to cover the battery during charging.
Due to high temperature in summer time, it is NOT advisable to charge it immediately after riding. In winter, it is FORBIDDEN to charge the battery in environment below 0℃. You are recommended to charge it in room temperature.
