Disc brake debugging
Excessive braking force
If you feel that the brake is too tight, use a wrench to loosen the brake arm nut 1 counterclockwise, return the brake cable to shorten the length of the exposed tail, and
lock the nut clockwise 1 to confirm the brake force and complete the adjustment.
Insufficient braking force
If you feel that the brake is too loose, use a wrench to turn the fine adjustment screw 3 counterclockwise, and then confirm the braking force by the brake action, and
tighten the limit nut 2 clockwise after completion.
Changing Brake Pads

Completely loosen the brake cable and remove the brake calipers from the vehicle body with a 4MM hexagon wrench.

Put the new brake discs in one by one, and push the two brake discs apart with tools.

Handlebar shaking debugging
Check whether the vertical tube screws are loose. If so, fasten the standpipe screws first, and then fasten
the two screws of the folding mechanism with a 6mm hexagon wrench.
