A creation device is provided that has at least one processor operatively coupled to non-transitory computer readable storage to execute operations that includes an acquisition part and a creation part. The acquisition part acquires input information concerning traveling of a human-powered vehicle. The creation part uses a learning algorithm to create a learning model that outputs output information concerning control of the components of the human-powered vehicle based on the input information.

An adaptable bicycle shifter making use of a torque computation algorithm based on the classical law of conservation of energy and employing a global positioning system (GPS) altimeter for sensing a road inclination, an accelerometer for sensing a bicycle acceleration and a hot wire anemometer for sensing a wind load, serving to automatically attenuate or appreciate programmed shifting speeds in real time to maintain rider standard shifting torques thereof. Adaptable 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 ongoing preference.

A human-powered vehicle control device is configured to control a derailleur in a suitable state. The human-powered vehicle control device includes an electronic controller configured to control a derailleur mounted to a human-powered vehicle based on a change in pressure of a tire detected by a pressure detector detecting the pressure of at least one tire of the human-powered vehicle.

A bicycle with an electric pedal assist motor capable of driving a chainring independent of cranks includes wheel speed sensors and crank cadence sensors. The wheel speed sensors and the crank cadence sensors measure wheel speed and crank cadence, respectively, and provide the measured wheel speed and crank cadence to controller of the bicycle. The controller activates motor overdrive based on the measured wheel speed and/or the measured crank cadence.

A bicycle control system may be configured to automatically control a bicycle, or components thereof. The bicycle control system may include a system control device configured to provide a simplified shifting system wherein large changes in speed associated with starting and stopping do not require the full attention of the automatic shifting system. The shifting system, or a system control device configured for controlling the shifting system, may be configured to determine when to enter an automatic shifting control mode, establish parameters for the automatic shifting of the automatic shifting control mode, and/or compare detected activities and values of the bicycle to the established parameters.
