  • BICYCLE TELESCOPIC APPARATUS
    Publication number: 20190193800
    Abstract: 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.
