Assembly

Visitwww.fafreesebike.com for additional help with assembly,including a step-by-step video walk-through.

If you do not feel comfortable assembling the bike yourself, we recommend taking your new bike to a bike shop for assembly and inspection. If you are willing to assemble the bike yourself, be sure to follow all instructions, properly adjust gears and brakes, and set tire pressure.

1. be careful not to position your fingers between the latch and the frame. Doing so may result in injury.

2. Unfold the rear wheel/ section and hold your e-bike upright with the kickstand. Push the latch closed so that it’s parallel with the bike’s frame then turn the latch lock down towards the latch to lock it in place.

3. Open the kick stand and place the entire bike.

1.Turn the handle up in the direction of the arrow.

2.Push the latch in the direction of the arrow to open the locking mechanism.

3. Fold the handlebar perpendicular to the ground.

4. Tighten the screws to fix the handlebar in place.

5.Erect the riser and press the handle in the direction of the arrow to lock it.

6. Adjust the height of the handlebar to an appropriate position.

For better pedaling, safety and overall riding comfort, positioning the seat at the right height is important. The rider’s leg length is used to determine the seat’s position. When you pedal, your hips should remain level and your legs should be almost fully extended at the bottom of the pedal stroke, but not over-extended.

To determine the right seat height, sit on the E-bike with one pedal at its lowest point and place the ball of your foot on the pedal. Your leg should be almost fully extended(not locked out) with a slight bend at the knee.

Open the quick release lever by swinging the lever open and outward fully.

Move the seat up and down by sliding the seatpost in or out of the seat tube.

Adjust the seat and the head of the seat is parallel with the top tube.

Close the quick release lever using your palm or finger.

Locate the right-side/ left side pedal, which is marked “R,” “L,”should have an “R””L,” sticker attached.

Thread the right pedal onto the right crank gently by hand, turning clockwise. Then tighten pedal by allen wrench.

Thread the left pedal onto the left crank gently by hand, turning counter- clockwise. Then tighten pedal by allen wrench.

Check the chain alignment. Rotate the right pedal and crank toward the back of the bike as though pedaling backward. Watch the chain and ensure the chain runs through the drivetrain (the rear cog, chain tensioner, and around the front chainring) smoothly.

Battery Key Positions

Familiarize yourself with the key port and key positions before riding the bike. The photo below shows the key port aligned in key position 1, in line with the ON icon. In key position 1, the battery is in the “on” position, with the battery locked to the frame, and the key can’t be removed.

(for battery removal)

• Anytime the battery is in key position 1, (on, locked to the frame) the display power button will turn the bike on and off, but the battery cannot be removed.
• If the battery is in key position 2, (off, locked to the frame) no buttons or controls can be activated, the bike will remain off, and the battery cannot be removed.
• Anytime the battery is in key position 3, (e, unlocked from the frame) the battery must be removed from the bike before moving or riding the bike. The key can be removed from battery.

NOTICE: You have to press the key then you can switch to unlock position

Start-up procedure

After the bike has been properly assembled according to the assembly video, all components are secured correctly, a certified, reputable mechanic has checked the assembly, and you have read this entire manual, turn on the bike and select a pedal assist level following the steps below:

1. Test the battery lock security. Ensure the key port is aligned with the OFF icon, which indicating the battery is off and locked onto the frame mount Carefully use both hands to pull up on the battery to test that the lock is secure.
2. Ensure proper handlebar and seat adjustment. Note that lowering the seat so the rider can put one or both feet flat on the ground without dismounting from the seat may offer a safer and more comfortable introduction to operating the bike. Ensure the handlebar faceplate bolts and seatpost quick release are fully and properly secured.
3. Turn the bike on/off. Insert the key and two clockwise to the ON position. Locate the LCD Display (near the left handlebar grip). Press and hold the center power button “FA” for approximately 3 seconds to tum on/off the bike.
4. Front light:Long press the “+” button to turn on/off the front light.
5. Select the desired level of pedal assistance (PAS) between level 0 through 3 using the + and- on the display remote. Level 1 corresponds to the lowest level of pedal assistance, and level 3 corresponds to the highest level of pedal assistance. Level 0 indicates pedal assistance is inactive. Start in PAS level 0 or 1 and adjust from there.
6. Begin riding carefully. With the proper safety gear and rider knowledge, you may now operate your bike. On a flat surface, in a low gear (1 or 2), most riders should be able to begin pedaling the bike with pedal assist level 0 or 1. You may also use the throttle to accelerate and maintain your desired speed.
7. The throttle is used by slowly and carefully press the throttle downward. Do not use the throttle unless you are on the bike.

Do not use the throttle while dismounted. Avoid accidental application of the throttle while dismounted; anytime you are moving the bike while dismounted, ensure the bike is powered off to prevent accidental application of the throttle.
