A hub assembly is provided for a human-powered vehicle. The hub assembly is basically provided with a hub axle, a hub body, an electric component and a user input device. The hub body is rotatably mounted on the hub axle to rotate around a rotational center axis of the hub assembly. The user input device is electrically coupled to the electric component.

A control device is provided for a human-powered vehicle that includes a generator configured to output electrical power, an electric power storage device electrically connected to the generator, and a component having an actuator actuated by electrical power from at least one of the generator and the electric power storage device. The control device includes a controller electrically connected to at least one of the generator and the electric power storage device. The controller is configured to control an operation state of the component in accordance with information relating to at least one of an output state of the generator and a store state of the electric power storage device.

A bicycle part includes a housing and a lid. The housing includes an inner peripheral portion, an outer peripheral portion, an end wall portion and a connecting portion. The outer peripheral portion is spaced radially outward from the inner peripheral portion with respect to a center axis of the enclosed area. The end wall portion interconnects the inner peripheral portion and the outer peripheral portion to at least partly define an internal space. The connecting portion interconnects the inner peripheral portion and the outer peripheral portion. The lid overlies the internal space. The lid is welded to the inner peripheral portion along an inner weld path and the outer peripheral portion along an outer weld path. The lid is further welded to at least part of the connecting portion of the housing a connecting weld path connecting the inner weld path and the outer weld path.

An electric power generator is provided for a human-powered vehicle. The electric power generator includes an axle, a stator, a rotor and a first electrical cable. The axle has a first axial end, and a second axial end. The stator has a first axial stator-end that faces the first axial end of the axle with respect to the rotational center axis and a second axial stator-end that faces the second axial end of the axle with respect to the rotational center axis. The rotor is rotatably mounted on the axle to rotate around a rotational center axis of the electric power generator. The first electrical cable is electrically connected to the stator on the first axial stator-end of the stator. The first electrical cable extends axially through the stator toward the second axial stator-end of the stator with respect to the rotational center axis.

A bicycle light that is constructed and arranged to be supplied with input electrical power. The power can be supplied by multiple power sources, or not. When there are multiple power sources, the bicycle light includes a circuit that is adapted to deliver power to the light source from any of the power sources. The bicycle light can have an electrical power output, and a circuit that is adapted to deliver power to the light source and the power output.

A charge system and a charge method adapted to a bicycle are provided. The charge system includes a hub dynamo, a power apparatus, a sensor and a control apparatus. The control apparatus is coupled to the hub dynamo, the power apparatus and the sensor. The sensor is adapted to sense a riding condition of the bicycle. According to the riding condition, the control apparatus selects a power supply pattern of the hub dynamo. When the power supply pattern is selected to be a stop pattern, a connection loop between the hub dynamo and the power apparatus is turned off by the control apparatus. When the power supply pattern is selected to a first pattern, the connection loop between the hub dynamo and the power apparatus is turned on by the control apparatus, such that the hub dynamo supplies power to the power apparatus at a first rate.

A bicycle frame assembly including a seat tube having first and second end portions (wherein the seat tube second end portion includes a bend and terminates in a first open end facing a first direction), a down tube having first and second end portions (wherein the down tube first end portion is mounted to the seat tube first end portion, and the down tube second end portion includes a bend and terminates in a second open end facing a second direction opposite to the first direction), and a top tube having first and second end portions (wherein the top tube first end portion is mounted to the seat tube second end portion and terminates in a third open end facing the first direction, and the top tube second end portion is mounted to the down tube second end portion and terminates in a fourth open end facing the second direction).

A power generating wheel rim device includes a wheel rim body, a power generating mechanism, a cover mechanism, and a circuit mechanism. The wheel rim body includes a central plate and a central slot recessed into the central plate. The power generating mechanism is embedded in the central slot and is operable to be driven by the wheel rim body to rotate and to generate electricity. The cover mechanism covers the power generating mechanism, is mounted to the central plate of the wheel rim body, and includes an air permeable passage structure that is annular and disposed along a periphery of the cover mechanism and that is in 10 spatial communication with an external environment and the central slot. The circuit mechanism is mounted in the cover mechanism and is electrically connected to the power generating mechanism for converting alternating current of the electricity generated into direct current.
