The electronic controller is configured to switch the plurality of control modes based on setting information related to an input to the human-powered vehicle.

Abstract: A brake system includes a driving part driven by electric power to adjust braking force applied to a rotary body of a human-powered vehicle and an electronic controller configured to control the driving part in accordance with a rotational state of the rotary body. The electronic controller has a plurality of control modes including a first mode that drives the driving part in accordance with a user operation and a second mode that does not drive the driving part regardless of the user operation. The electronic controller is configured to switch the plurality of control modes based on setting information related to an input to the human-powered vehicle.

Abstract: A brake control device and a brake system are configured to appropriately apply a braking force to a rotary body of a human-powered vehicle. The brake control device includes an electronic controller that controls a braking portion electrically driven to brake a rotary body rotating in accordance with traveling of a human-powered vehicle. The electronic controller controls the braking portion in accordance with an operation amount of an operating device and a state related to the human-powered vehicle.

Abstract: A human-powered vehicle system and a control method are provided that reduce power consumption of a detection device. The human-powered vehicle system includes an electronic controller having at least one processor configured to control a detection device provided at a human-powered vehicle to detect an electromagnetic wave having a frequency that is greater than or equal to 30 GHz and excluding visible light. The at least one processor is configured to control the detection device in at least one of a first mode and a second mode that consumes less power than the first mode.

Abstract: To provide a brake device and an electric brake system that appropriately brakes a rotary body of a human powered vehicle in various situations, a brake device is applicable to a human powered vehicle and includes an electric actuator operated by electric power from a power supply, a braking portion driven by the electric actuator to brake a rotary body of the human powered vehicle, and a power storage provided separately from the power supply to supply electric power to the electric actuator.

Abstract: An electric brake system that appropriately brakes a rotary body of a human powered vehicle in various situations is applicable to a human powered vehicle and includes a brake device including an electric actuator operated by electric power from a power supply, and a braking portion driven by the electric actuator to brake a rotary body of the human powered vehicle, a state detector detecting a state of the human powered vehicle other than an operation of the brake device performed by a user, and a control unit controlling the brake device so that the braking portion brakes the rotary body based on a detection result of the state detector.

Abstract: A bicycle electric component comprises a wireless communicator and a detector. The wireless communicator is configured to receive a wireless signal. The wireless communicator has a first operating mode and a second operating mode. A power consumption of the second operating mode is lower than a power consumption of the first operating mode. The detector is to detect an operational state of a bicycle. The wireless communicator is configured to change from the second operating mode to the first operating mode in a state where the wireless communicator receives the wireless signal and the detector detects the operational state of the bicycle.

Abstract: A tread portion is provided with a first block and a second block, which protrudes outward in a tire width direction more than the first block, alternately in a tire circumferential direction in a shoulder region. A first projection is provided in an outer side of the first block, and a second projection is provided in an outer side of the second block. An outside end of the second projection is connected to a side surface of the second block and is arranged closer to an outer side in the tire diametrical direction than an outside end of the first projection. An angle ?1 formed by a side surface of the first projection and a surface of the side wall portion is equal to or smaller than an angle ?2 formed by a side surface of the second projection and the surface of the side wall portion.

Abstract: A pneumatic tire includes a rib formed in a center region of a tread portion and extending continuously in a tire circumferential direction. The rib has a plurality of respective recessed portions disposed along the tire circumferential direction at a center portion thereof. A bottom surface of each of the plurality of recessed portions is formed of a pair of inclined surfaces respectively deepened toward both sides. A groove portion extending in a tire width direction toward a kicking-out side in the tire circumferential direction is configured to communicate with one side of the recessed portion.

Abstract: A pneumatic tire includes a tread having at least one main groove and a plurality of ribs extending in the tire-circumferential direction. At least one of the ribs has a plurality of narrow grooves formed at intervals in the tire-circumferential direction. At least one intermittent sipe is formed corresponding to at least one of the narrow grooves. The narrow grooves are grooves each having a portion extending substantially along the tire-circumferential direction and having a groove width smaller than the at least one main groove. The at least one intermittent sipe has a plurality of holes that are intermittently formed, and at least one solid part located between adjacent two of the holes. The holes and the solid part are arranged in a direction intersecting the narrow grooves. The intermittent sipe intersects the corresponding narrow groove in the at least one solid part.
