1.Preparation #
You will need a 4mm hex wrench (as shown in the image below).
2.Notes #
(1).If your E-bike is equipped with a saddle adjustment function, the control switch can be found as shown in the image below.
(2).The saddle adjustment switch wire should be positioned between the brake line and the 1T4 wire, as shown in the image below: ① is the brake line, ② is the saddle adjustment switch wire, and ③ is the 1T4 wire.
3.Installation Steps #
(1).Use a 4mm Allen wrench to loosen the saddle adjustment switch screw by rotating it in the direction of the arrow, as shown in the image below.
(2).The installation position of the saddle adjustment switch is on the bracket between the throttle and brake lever, as shown in the image below.
(3).Both holes on the saddle adjustment switch can be used for installation. You can choose one of them based on your usage habits, as shown in the image below.
(4).Place the saddle adjustment switch behind the bracket, aligning the holes, and insert the screws for the switch. Use a 4mm hex wrench to tighten the screws by rotating them in the direction of the arrow, as shown in the image below. The tightening force should be between 3-5 N·m, which is approximately 0.306 to 0.51 kgf.
