Assembling Your E-Bike

1. Read all of the instructions carefully. Be familiar with the proper operation of all items.
2. 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.
3. Our QA mechanics have assembled and tested your bike beforehand.
4.  To assemble your bike, work on a clean area with enough space to maneuver.
5.  If installed, remove the battery from the bike to start the assembly。
6. Inspect the bike completely to be sure no damage occurred during shipping.
7. The kickstand is designed to support the bicycle only. Not the rider mounted。
8. You can adjust your saddle position and the tilt on your handlebar items for comfort.
9.  Check all screws and parts are tight and properly fixed. We recommend a pre-trip inspection before your first rides.

Installing Your Handlebar

1. Place the handlebar in the handlebar mount being careful with the wires.

2.  Face the mounting brackets on the front end of the mount with the round edges facing outward.
   Adjust the handlebar angle to your comfortable riding posture.

3.  Secure the mounting brackets with four screws. (4mm allen wrench with 6Nm strength)

4. Verify your front tire lines up with your headset.

5.  Check whether all headset items are tight.

Reseat the Right Brake Lever

The brake lever on the right hand is turned aside for packing and transportation purpose. You will need to adjust the brake lever to the correct position in parallel with the left brake lever. Use 4mm allen wrench with 8Nm torque to secure the brake lever screws after adjustment.

Installing Your Front Wheel

1.  Insert the front wheel in between the front fork on the bike. Be sure the fork is resting on the outside of the axle.
2.  Align the disk between the brake caliper as shown in Figure 2.
3. Insert the skewer into the wheel axle as seen shown. Keep the spring, cam follower, and lever on the LEFT side, nearest the disk brake. Keep the adjustment nut and spring on the RIGHT side. (See Figure 2)
4.  Screw the skewer into the end nut until almost tight.
5.  Lift the lever up until parallel with the front fork. You should feel the axle tighten into the front forks. Your front wheel is now installed.

Installing Your Headlight

1. Place the headlight with its bracket in front of the fork gantry. Thread the screw through the fork gantry and secure with a washer and a fixing nut. (You will need to secure the fixing nut tightly so the screw doesn’t turn).
2. Connect the headlight cable with the wire coming out from the downtube.

Installing Your Pedals

1. Warning: Incorrect installation will cause damage. Please read the instructions and watch our videos if needed.

2. 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).

3. Sitting on your bike the pedals go on the Left and Right side respectively.

4. Keep the pedal Horizontal while hand screwing to get the thread started. Then Use your 15mm wrench to tighten them.

5.  Both pedals tighten towards the front of the bike. The left pedal is reverse threaded to allow this.

6.  The pedals need to be very tight (at least 25-35Nm torque), be sure to retighten after your first couple rides.

Preparations Before Riding

1. Read all instructions carefully, be familiar with the proper operation of all items. Check for detailed information and guidance on our product page.

Notes of Charging:

1. Charging time varies from 10 to 12 hours with a standard 2A charger.

2.  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.

3. Insufficient charging will not influence the battery lifecycle. AVOIDING deep discharge is helpful to protect the battery and extend its lifecycle.

4.  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.

5. 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.

6.  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.
