A stem assembly and an electric vehicle are provided. The stem assembly includes: a stem telescoping mechanism including a first hollow tube, a second hollow tube, and a locking mechanism, the locking mechanism having a locked state and an movable state; a handle folding mechanism arranged to the stem telescoping mechanism, the handle folding mechanism including a handle assembly and a first limiting member, the first limiting member being movably arranged, and having a first limiting position and a first evading position; and a driving mechanism connected to both the locking mechanism and the first limiting member, and configured to be operated to control the stem telescoping mechanism and the handle folding mechanism to synchronously move.

A transportation apparatus (1) comprises a frame (12) having an engagement portion or receiving portion (14) adapted to receive one or more occupant support devices (16); and drive means (20) configured to enable an occupant of the transportation apparatus (1) to power, drive and/or steer the transportation apparatus (1). The drive means (20) has a first configuration or position and a second configuration or position, wherein the drive means (20) is closer to the engagement portion or receiving portion (14) of the frame (12) in the second configuration or position than in the first configuration or position.

A personal mobility and a control method thereof may include a main body, a steering shaft rotatably coupled to the main body, a steering limiting device configured to limit rotation of the steering shaft, a posture sensor provided to detect a change in posture of the main body, and a controller configured to selectively generate a control signal to control an operation of the steering limiting device to limit the rotation of the steering shaft when the controller determines that the posture of the main body changes at a speed exceeding a predetermined speed.
