An operating device for a human-powered vehicle comprises a base structure, a first switch unit, and a second switch unit. The base structure defines a mounting axis. The first switch unit comprises a first switch base member, a first switch, and a first point. The first point is closest to the mounting axis along a first direction parallel to a first pivot axis. The second switch unit comprises a second switch base member, a second switch, and a second point. The second point is closest to the mounting axis along a second direction parallel to a second pivot axis. A second minimum distance is longer than a first minimum distance. A third minimum distance is longer than a fourth minimum distance.

A vehicle, e.g., a two-wheeled electric vehicle, is operable in a low-speed mode, in which the vehicle can be propelled selectively in the forward or reverse direction, at a speed limited to approximately an average person's walking speed, e.g., approximately 3 mph. The amount of torque driving the vehicle is controlled so that higher torque is available to propel the vehicle at lower speeds and lower torque is available to propel the vehicle at higher speeds. The maximum torque of the vehicle's electric motor is available to propel the vehicle at a standstill.

An operating system for a human-powered vehicle comprises a first operating device, a second operating device, a first user interface, and a second user interface. The first operating device comprises a first base member and a first operating member. The second operating device comprises a second base member and a second operating member. The first user interface is configured to receive a first user input and mounted to the first operating device. The second user interface is configured to receive a second user input and mounted to the second operating device. At least one of the first user interface and the second user interface is configured to be operated to control an assist driving unit configured to assist a human power.

An operating device for a human-powered vehicle comprises a base member, an informing unit, and an operating member. The base member is configured to be mounted to a handlebar. The informing unit is configured to inform a user of first information relating to an assist driving unit configured to assist a human power. The operating member is movably coupled to the base member to control a component different from the assist driving unit.

An electric bicycle includes: a sleeve to which power for driving the electric bicycle is input; a rear wheel; and a power transmission mechanism that transmits the power input to the sleeve to the rear wheel. The electric bicycle determines an abnormality of the power transmission mechanism or prevents or prohibits driving performed by using the power transmission mechanism based on a reference composite gear ratio of the power transmission mechanism acquired at a first time and current composite gear ratio of the power transmission mechanism acquired at a second time subsequent to the first time.

A control system for a human-powered vehicle includes an input device, an additional input device, and a controller. The input device is configured to receive manual input from a rider. The additional input device is configured to receive manual input from the rider. The controller is configured to control a shifting device of the human-powered vehicle based on one of an output signal from the input device and an output signal from the additional input device. The controller is configured to output one of a first control signal for a single shifting operation and a second control signal for a multiple shifting operation in response to the manual input received by one of the input device and the additional input device. The controller is further configured to output one of a first control signal and a second control signal based on a state of the human-powered vehicle.

A bicycle derailleur comprises a circuit board, an electrical user interface, a motor housing, and a motor unit. The electrical user interface includes a user accessing portion configured to receive a user input. The motor housing includes a motor accommodating space. The motor unit is provided in the motor accommodating space and configured to generate rotational force and configured to be electrically connected to the circuit board. A first direction is defined from the circuit board toward the electrical user interface or from the electrical user interface toward the circuit board. The plurality of second directions is defined to be perpendicular to the first direction. The motor unit is at least partly provided between the user accessing portion of the electrical user interface and the circuit board when viewed in at least one of the plurality of second directions.

A highly adaptable user interface for gearing based bicycle power transmission devices powered by a linear servo actuator slaved to an electronic control system serving to automatically shift into desirable gearing ratios under user predefined shifting criteria adaptable in real time to rider conditioning, comfort level and road conditions thereby alleviating manual shifting tasks and achieving optimal pedal rate and effort settings for the rider. Ability to switch to manual mode augments rider total control of disclosed device.

A human-powered vehicle control device includes an electronic controller for controlling a transmission that changes a ratio of a rotational speed of a drive wheel to a rotational speed of a crank of the human-powered vehicle. The electronic controller switches the transmission from a first control state to a second control state in accordance with at least one of a human drive force, a rider's posture, a vehicle body attitude, a handle force, and a human-powered vehicle travel state, In the first control state, the electronic controller controls the transmission to change the ratio in accordance with an operation of a shift operating unit. In the second control state, irrespective of the operation of the shift operating unit, the electronic controller controls the transmission such that the ratio increases in accordance with the travel state of the human-powered vehicle and/or a travel environment of the human-powered vehicle.
