[0037] refer to Figure 1 In order to facilitate installation and maintenance, a cover plate 19 is installed on the frame tube 1. The cover plate 19 is used to close the inner cavity of the frame tube 1 and protect the parts inside the frame tube 1.

[0038] Operation: The shared e-bike's central control system sends commands to the drive motor 7, which then rotates forward or reverse according to the corresponding commands. This in turn drives the drive screw 6, which in turn raises or lowers the connector 5 under the pressure of the inner tube 4. This in turn raises or lowers the inner tube 4, thereby raising or lowering the saddle to adjust the saddle height. This command can be operated directly in the mobile app: one option is automatic adjustment, which adjusts the saddle height by inputting your height, and the other is manual adjustment, which adjusts in increments of 10-15mm. The current saddle height is determined by the positioning sensor 9 detecting the position of the positioning magnet 8.
