Front Fork Installation

◆Handlebar Installation ( 4mm Hex Wrench )
Step 1 : Loosen the bolts on your bike stem.
8
Step 2:
Step 3:
Center your handlebars and rotate them to align to the marking pointed to in the below image.
Tighten bolts to handlebar stem, but don’t tighten completely as you may want to further adjust the angle later to align more precisely. Test the
positioning, and adjust the handlebar to your preferred angle. After determining the best position, completely tighten all the bolts on the stem.
NOTICE: In addition to angle,
the height of the handlebar
can be adjusted by adding or
removing the headset spacers
if needed. For those without
experience, we recommend
having a professional make
such adjustments for safety
reasons.
Assembly Instructions

◆Front wheel
Step 1 : Take out the black guard block of the front fork. Pull out the red pad, which is used to protect the hydraulic brake caliper.
Step 2: Roll the wheel in between the front fork. Align the fork dropouts with the axle of the wheel hub, making sure the dropouts are fully
seated on the axle. Also, ensure the brake rotor is properly inserted into the caliper.
Step 3: Prepare your quick-release skewer for the next step by removing the thumb nut and one of the cone springs.
9

Step 4 : Install quick-release strings from the side without brake discs, inserting the quick-release skewer through the hub, and then replacing the
second cone spring on the other side. Ensure both springs are pointed narrow-side-in towards the wheel hub.
Step 5 : Tighten the thumb nut until the quick-release lever is held in line with the axle, and then use your palm of your hand to close the quick-release lever.
WARNING: Do not pull the brake lever without having either the red pad or the brake disc inserted, as this will damage the hydraulic brake caliper.
10

Step 6 : Inflate the tires and make sure they have sufficient pressure forriding comfort and safety, not exceeding the limit specified on the sidewall.
Step 7 : Rotate the front wheel. Make sure to fully close the quick release skewer lever on the front wheel and check the wheel balance in Pedal Only Mode. If
notice the riding is imbalanced or the rotation of the front wheel makes noise, it means the bolts were not completely tightened or not aligned you
horizontally.

◆Headlight (4mm Hex Wrench & 10mm Wrench)
Step 1 : Loosen the bolts on the fork brace. While holding the nut with a 1 0 mm wrench, unscrew the bolt with a 4 mm hex wrench.
Step 2 : Align the bolt holes of both your front light and the front fender together with the hole on the fork brace, then reinsert thebolt through all holes
and tighten the bolt with a 1 0 mm wrench and a hex wrench. Make sure the washer is directly under the bolt head.

◆Pedals Installation (15mm Wrench)
Make sure your pedals are installed on the correct side, as installing on the wrong side will damage the threads. Indicators for the right pedal ( R) and the left can
be found in two places: the stickers on the plastic cover, and the bottom of the pedal threads.
Before you install the pedals, apply a small amount of waterproof grease onto the spindle. Start threading the pedal on by hand to ensure the pedal is going in
perfectly straight, rotating in the direction of the pointer shown on the crank. If it is not spinning smoothly, make doubly sure that you have each pedal on the correct
side. After initial hand-tightening, finish tightening the pedals with a standard 15 mm wrench .

◆Seat Adjustment
Adjust the Seat Height:
Open the seatpost quick release lever.position. Do not extend the seatpost beyond the minimum insertion marking etched onto the seatpost
Adjust the seatpost height by sliding the seatpost up or down to a height appropriate foryour leg length and prefered riding
WARNING: Overextending the seatpost can cause it to break or come off your bike, putting you at very high risk of serious injury or
death. Avoid this danger by inserting your seatpost into the seat tube far enough that the minimum insertion point is no longer visible.

Adjust the Seat Angle:
Loosen the seat adjustment bolt beneath the seat. Move the seat backward or forward and tilt to adjust the angle within the limit markings etched on the seat
rail. Do not exceed the limit markings, to ensure the safety of yourself and the bike.
Tighten the seat adjustment bolt. Ensure the top and bottom of the seat rail clamp are aligned, so that the seat adjustment bolt will clamp the seat rails
together properly.
Step 1:
Step 2:
NOTICE: The seat angle has been preadjusted to factory safety standards. Please make note of original settings, and only adjust if necessary.
