A vehicle includes: a vehicle body frame; a drive unit provided on the vehicle body frame and movable on a floor surface; a seat disposed above the vehicle body frame to support buttocks of a user; a lift unit provided between the vehicle body frame and the seat to raise and lower the seat between a low position and a high position; at least one first leg extending downward from the seat and provided with a roller at a lower end thereof; and at least one second leg extending downward from the seat and provided with a contact member at a lower end thereof. When the seat is in the high position, the roller and the contact member are separated from the floor surface, and when the seat is in the low position, the roller and the contact member contact the floor surface.

A vehicle 1 includes a vehicle body frame 2, a drive unit 3 provided in the vehicle body frame and movable on a floor, a seat 4 arranged above the vehicle body frame and supporting the buttocks of a user, a lifting device 5 provided between the vehicle body frame and the seat and lifting or lowering the seat between a low position and a high position, a battery 7 provided in the vehicle body frame, and a control device 6 controlling the drive unit and the lifting device. The control device prohibits lifting drive of the lifting device in response to the seat being at the low position and a lifting prohibition condition being satisfied.

A bicycle telescopic apparatus includes a first tube, a second tube, a positioning structure, a memory, and a controller. The second tube is telescopically received in the first tube and configured to be adjustably movable with respect to the first tube in a longitudinal direction of the bicycle telescopic apparatus. The positioning structure includes an electrical actuator to adjustably position the second tube relative to the first tube in the longitudinal direction. The memory is configured to store setting information for a predetermined relative position of the first tube and the second tube, and the setting information is changed via an electrical setting operation. The controller is configured to control the electrical actuator to position the second tube relative to the first tube at the predetermined relative position.
