An operating device is provided for a human-powered vehicle. The operating device basically includes a base, a first operating member, a first electric switch, a first load generator and an operating load adjuster. The first operating member is movably arranged with respect to the base. The first electric switch is provided to the base and arranged to be activated by movement of the first operating member. The first load generator is configured to generate an operating load applied to the first operating member. The operating load adjuster is configured to adjust a transition of the operating load from a first load transition to a second load transition different from the first load transition.

A human-powered vehicle includes a crank axle, a first rotational body, a wheel, a second rotational body, a transmission body that transmits a driving force between the first rotational body and the second rotational body, a derailleur configured to operate the transmission body to change a transmission ratio, and a motor configured to drive the transmission body. A control device has an electronic controller configured to control the motor and drive the transmission body with the motor so as to change at least one of a rotational angle of the motor and an output torque of the motor in correspondence with a state of the human-powered vehicle upon determining the derailleur has been actuated to change the transmission ratio and a predetermined condition related to pedaling is satisfied.

An automatic bicycle shifter making use of a global positioning system (GPS) altimeter for sensing road inclination, an accelerometer for sensing bicycle acceleration and a hot wire anemometer for sensing wind load, and through application of classical law of conservation of energy attenuates or appreciate automatic shifting speeds in real time to maintain a rider standard shifting torque. Automatic bicycle shifter is additionally provided with capability to sense, record, and interpret rider automatic shift override commands and further adjust automatic shift criteria to rider preference.

A derailleur for a human-powered vehicle comprises a base member, a movable member, a linkage, an electrical actuator, a first biasing member, and a second biasing member. The base member is configured to be attached to a vehicle body of the human-powered vehicle. The movable member is configured to be movable relative to the base member in a first direction and a second direction different from the first direction. The linkage is configured to movably connect the movable member to the base member. The electrical actuator is configured to operatively move the movable member relative to the base member. The first biasing member is configured to deform if first external force is applied to move the movable member in the first direction. The second biasing member is configured to deform if second external force is applied to move the movable member in the second direction.

A method for controlling electronic shifting of a bicycle includes identifying, by a processor, a gear shift command. The processor adjusts a cadence band based on the identified gear shift command. The cadence band includes an upper cadence limit and a lower cadence limit. Adjusting the cadence band includes increasing the upper cadence limit, decreasing the lower cadence limit, or increasing the upper cadence limit and decreasing the lower cadence limit. The electronic shifting of the bicycle is controlled based on the adjusted cadence band.

A method for controlling electronic shifting of a bicycle includes identifying, by a processor, a torque at a crank arm of the bicycle. The processor compares the identified torque or a parameter based on the identified torque to a predetermined band. The predetermined band has an upper limit and a lower limit. The processor determines a target cadence based on the comparison. The processor determines a cadence band based on the determined target cadence. The method also includes controlling the electronic shifting of the bicycle based on the determined cadence band. The controlling of the electronic shifting of the bicycle includes actuating a motor of a derailleur of the bicycle for the electronic shifting of the bicycle when a cadence of the bicycle is outside of the determined cadence band.
