Assembling with the help of the video guide is the recommended method to reduce questions or issues with assembly.
Preassembly tips and advice
- If you are uncomfortable with bike mechanics, it is best to have it assembled by a bike shop or expert.
- Carefully remove ONLY the packing zip ties, do not cut any wires, cables, or zip ties that are used to route wires.
- You will remove all small parts from the fork steerer tube prior to installing the fork.
- The headset construction is historically the most difficult part for many customers.
- Pro tip: follow the assembly video steps at 1/4 speed.
- There is a plastic spacer supporting the front brake caliper between the brake pad area. Note that squeezing the brake lever without the spacer or bike rotor installed will clamp the pistons closed. It is recommended to save the spacer to use anytime you remove the front wheel.
- Avoid touching the brake rotors with your fingers. The natural oil present on your hands will contaminate the rotors, reduce braking efficacy and create a loud whining pitch when braking.
- Apply grease to the pedal threads, seat post and fork steerer tube before installation
Front Brake Caliper- The front brake caliper has two different length bolts. For proper installation, the longer bolt and thicker section of the spacer will be facing upwards
Note: Proper installation of the headset will avoid damage to the bike or injury while operating your ebike.
Pro Tip: Rewatch the assembly video headset section in 1/4 speed to follow the steps carefully
Steerer Tube-Carefully install the fork steerer tube, making sure it is seated with the lower bearing at the bottom of the head tube. Only the crown race (which is not removeable) should be on the fork steerer tube at this time.
Compression Ring- Once the fork is installed through the head tube, place the compression ring on the top of the fork steerer tube. Slide it down to insert inside the top of the headtube. When seated correctly, this ensures the steerer tube is properly centered. This may take some adjustment to seat it perfectly.
Cone Spacer- Next slide the cone spacer onto the steerer tube. Confirm the dust cover is attached to the cone spacer. This will ensure dust and debris does not enter the headtube.
Stem Spacers- Slide remaining spacers on the steerer tube.
Stem- Place the stem onto the steerer tube. Do not tighten any hardware
Top Cap and Bolt- Place the top cap over the stem and carefully tighten the top cap bolt until you begin to feel slight resistance rotating the fork.
Proper Headset Installation- Confirm that the fork turns smoothly.
- Confirm that the fork does not shift up or down relative to the head tube.
- If the fork shifts within the headtube, grinds while turning or gives resistance to turning, reverse steps and ensure you have installed all parts in the order shown in the assembly video.
Install Stem- Tighten bolts on stem where it connects to steerer tube. Carefully and slowly tighten in a star pattern with even spacing. Do not over tighten or you will damage the stem.
Final Check- Ensure there is no "play" in the fork. If the fork is properly seated and tightened, the fork should not shift up and down relative to the head tube of the frame.
