5. Tighten the 4 screws. You should keep swapping between the
screws to ensure that the faceplate has a consistent gap from the
stem along all edges and tighten securely. The handlebar should
be aligned so that the once front wheel is installed, the brake
levers are at 45 degrees to the ground.
6. Tighten the screw under the black rubber cover where on the
top of the fork.
7. Align the stem with the front wheel. Tighten the two screws on
the sides of the stem.
Front wheel
1. Turn the bike upside down on the ground. Put the soft foam
under the handlebar to prevent crushing the display, phone
holder and other parts.
2. Remove the nuts and washers at both sides of the front motor.
Please remember the order of the washers.
3. Lift the front wheel, then insert the disc rotor into the caliper.
Insert the axle into the grooves of the fork. Make sure that they
engage on the fork nicely. There are two washers with hooks on
both sides of the motor. Remember the hooks of the washers are
always embedded in the grooves of the front fork. So the front
motor can be fixed.
4. Tighten the nuts with a wrench. Keep the wheel in the center of
the front fork when tightening it. Put the rubber covers on the
nuts.
