A shock-absorbing front fork assembly of a motorcycle includes a front fork, a pressure buffering cylinder and a control valve disposed between the front fork and the pressure buffering cylinder and electrically connected with a brake system to control the communication between the front fork and the pressure buffering cylinder according to the operation of the brake system. When the brake system is not actuated, the control valve is open to make the front fork communicate with the pressure buffering cylinder, thereby making the spring supporting force relatively smaller. When the brake system is actuated, the control valve is close to make the front fork not communicate with the pressure buffering cylinder, thereby making the spring supporting force relatively larger. Therefore, the spring supporting force is adjusted by the brake operation, that raises the riding comfort and safety.

A bicycle accessories connection unit includes a body having an installation hole defined axially therethrough so as to be connected with an accessory. At least one connection hole are defined radially in the body and at least one connection member is connected to the at least one connection hole so as to be connected to another accessory. A link is connected between the body and a bicycle frame. Multiple accessory are connected to the single body.

A charging system includes a charging station and a power converter. The charging station includes a power output device for outputting a first DC power. The power converter includes a housing and a converting device. The housing has a battery socket that has an output connecting port and is adapted to be engaged with a LiFePO4 battery. The output connecting port is detachably and electrically connected to a connecting port of the LiFePO4 battery. The converting device is disposed in the housing and is electrically connected to the power output device and the output connecting port. The converting device converts the first DC power into a second DC power to charge the LiFePO4 battery.

A bicycle image capturing device is provided that reduces annoying operations for changing an operation state. The bicycle image capturing device includes a controller. The controller includes a reception unit and an electronic control unit. The reception unit is configured to obtain information related to a component of a bicycle. The bicycle component is operable in at least a first state and a second state that differs from the first state. The electronic control unit is configured to control a first image capturing unit based on the information obtained by the reception unit.
