A bicycle electric telescopic apparatus comprises a first tube, a second tube, a positioning structure, an electric positioning actuator, and a power supply. The first tube has a center axis. The second tube is telescopically received in the first tube. The positioning structure is configured to relatively position the first tube and the second tube in a telescopic direction extending along the center axis of the first tube. The electric positioning actuator is configured to actuate the positioning structure. The power supply is configured to be detachably and electrically connected to the electric positioning actuator. The power supply is configured to be detachably and electrically connected to an additional bicycle electric telescopic apparatus.

The present invention relates to an sound emitting device. The sound emitting device includes a housing, a memory device. The housing includes a slot. The memory device carries a first number of a sound groups. In addition, each group contains a second number of sounds. The housing is configured to removably receive the memory device. The housing is configured to removably receive the memory device. The housing carries a plurality of actuators. In addition, number of actuators are more than the first number. Each sound group is selected using one of the plurality of actuators. At least one actuator is used to toggle between sounds of the selected group.

A bicycle controller is provided that performs control in accordance with a riding condition of a bicycle. The bicycle controller includes an electronic control unit that controls a motor. The motor assists human power that is inputted to a bicycle. Upon determining a gear changer that changes a gear ratio of the bicycle is operated, the electronic control unit switches a control state of the motor from a first control state to a second control state based on a rotation phase of a crank of the bicycle and changes a timing at which the control state of the motor is switched from the first control state to the second control state based on an inclination of the bicycle in a front-rear direction.

A bicycle operating device, having a center axis, comprises a mounting structure configured to be press fitted into a free end of a bicycle handlebar; and an operating structure for an operation of a bicycle component, the operating structure being coupled to the mounting structure.
