Assembly Steps
Follow these 4 steps in order. Each step matches the assembly video and the model-specific PDF manual.
Install the Handlebar
The handlebar must be inserted at least 2 inches deep into the head tube. A shallow insertion is a safety risk. Do not skip the depth check.
- Insert the handlebar into the head tube, pushing it down at least 2 inches deep.
- Align the handlebar so it is straight and centered with the front wheel.
- Fasten the screw in the middle position of the handlebar by turning it clockwise until the handlebar is held securely.
- Wrap the soft handlebar pad around the center of the handlebar.
- Fasten the pad in place by pressing the velcro straps firmly together.
Attach the Front Wheel
The axle retention devices go on before the axle bolts. Install them in the correct order to ensure the wheel stays securely in place.
- Remove the axle bolts and retention devices from the front wheel.
- Insert the wheel axle between the fork tubes so the axle fits into the slots at the end of the fork blades.
- Install the axle retention devices on each side of the axle.
- Install the axle bolts on each side of the axle.
- Use the included adjustable wrench to tighten the axle bolts securely.
Install the Seat
Set the seat height before locking the clamp. A good starting height lets your child sit with both feet flat on the ground and a slight bend in the knee.
- Insert the seat post into the seat tube on the frame.
- Slide the post to your child's correct seat height. See the seat height adjustment section below for guidance.
- Fasten the seat clamp by turning the screw clockwise until snug.
- Press the lever down firmly to lock the seat post in place.
Install the Kickstand
- Position the kickstand on the designated mounting point on the frame.
- Align the kickstand bracket with the mounting holes.
- Insert and fasten both screws by turning them clockwise.
- Tighten both screws securely using the included assembly tools.
Seat Height Adjustment
The KB-BMX01 seat is adjustable between 15" and 22.6". You can re-adjust the height as your child grows without any extra tools.
The right seat height lets your child sit with both feet flat on the ground and a slight bend at the knee. If their legs are fully straight or they cannot reach the ground, adjust the height before riding.
How to Adjust the Seat Height
- Press the lever on the seat clamp upward to release it.
- Turn the clamp screw counterclockwise a few turns to loosen.
- Slide the seat post up or down to the new height.
- Turn the clamp screw clockwise until snug.
- Press the lever firmly back down to lock the post in place.
- Ask your child to sit on the seat and confirm they can place both feet flat on the ground.
Do not raise the seat above the maximum height mark on the seat post. The minimum insertion depth marking must remain inside the frame at all times.
