A human-powered vehicle control device includes an electronic controller that controls a motor. The motor assists in propulsion of a human-powered vehicle including a transmission configured to change, in steps, a first ratio of a rotational speed of a drive wheel to a rotational speed of a rotary body to which human drive force is input. The controller changes a motor control state from a third control state to a fourth control state when the first ratio is changed by the transmission or a signal is received for changing the first ratio. The controller changes the motor control state from the fourth control state to a fifth control state in accordance with a value related to at least one of a speed of the human-powered vehicle, the human drive force, an inclination angle of the human-powered vehicle, and a state of a rider of the human-powered vehicle.

A connecting-state detection system for a power supply system of a human-powered vehicle comprises a detector. The power supply system includes a power supply device having a plurality of connecting terminals. The detector is configured to detect a connecting state of each of the plurality of the connecting terminals.

A control device is provided for a human-powered vehicle. The control device is basically provided with a controller. The controller is configured to be connected to at least one component of the human-powered vehicle such that the controller is free from executing normal activation of the at least one component in accordance to a first input in a first mode. The controller is configured to operate at least one of an actuator and an indicator in accordance to the first input in a second mode. The first mode is switched into the second mode in accordance to a second input different from the first input.

A method is described for operating a two-wheeled vehicle, in particular a motorcycle, on a roadway, the method including the following steps: ascertaining an instantaneous coefficient of friction between at least one wheel of the two-wheeled vehicle and the roadway; calculating a critical tilt angle of the two-wheeled vehicle as a function of at least the instantaneous coefficient of friction; detecting an instantaneous tilt angle of the two-wheeled vehicle; determining the distance between the instantaneous tilt angle and the critical tilt angle; and outputting an item of information to the driver as a function of the determined distance.

A system for adjusting the damper force on the suspension system of a bicycle is provided. Sensors are placed on the front shock and rear shock to measure the amplitude of displacement or acceleration in the time domain and generate a zenith position, velocity, force, and work based on the measured values. The system calculates a curve fit approximation curve for the relationships of zenith position versus velocity and uses the approximation curves to generate and display recommended damper settings for the front shock and rear shock. Using the data ensures that the bicycle suspension data is balanced, such that the front shock and rear shock respond similarly to the same event.

The present disclosure describes a controller for a light electric vehicle. The controller may include a user interface that includes one or more visual indicators and selectable buttons. The visual indicators may be used to convey various status indicators and/or alerts to an individual that is riding the light electric vehicle. The selectable buttons may be used to alter an operating state of the light electric vehicle and/or to provide operating status information about the light electric vehicle.

Systems, devices, and methods for detection of a scooter riding environment are described. A scooter alarm and pedestrian walkway detection system includes an alarm, a movement sensor configured to detect motion of a scooter and transmit motion data indicative of the motion to a processor, and an image capture device configured to detect features of a riding environment of the scooter and transmit riding environment data indicative of the features to the processor. The processor is configured to determine whether the riding environment of the scooter is a pedestrian walkway based on the motion data and the riding environment data. The processor is configured to activate the alarm in response to determining that the riding environment of the scooter is a pedestrian walkway.

Techniques are disclosed for systems and methods associated with a powertrain for a micro-mobility fleet vehicle. The fleet vehicle may include at least one drive wheel to provide tractive contact between the flee vehicle and a road surface, an electric motor mechanically coupled to the drive wheel and configured to provide motive force for the fleet vehicle, a brake resistor configured to provide dynamic braking of the motor, and a motor controller electronically coupling the brake resistor to the motor. The motor controller may be configured to control the motive force provided by the motor using the brake resistor. The motor controller may be configured to limit a speed, power, and/or acceleration of the motor using the brake resistor based on an operational environment of, and/or on a directive received by, the fleet vehicle. The brake resistor may provide a relatively wide range of traction control for the fleet vehicle.

The present invention relates to a bicycle with feedback. The bicycle includes a tube assembly including a frame with mutually fixed tube elements and movable tube elements, such as steering tube and a handlebar, at least one subsystem for providing a respective function to the bicycle, and a control unit for functional interaction with the at least one subsystem . The control unit includes receiving means for receiving at least one status signal of the at least one subsystem, a processing means, such as a processing unit for processing the at least one status signal, and output means for outputting at least one output signal. The bicycle further includes a sound system, including a loudspeaker for outputting sound, a power supply, such as a battery, for providing power to the control unit and to the at least one subsystem. The sound system is arranged for outputting sound as a sound feedback based on the at least one status signal of the at least one subsystem.
