An apparatus for a bicycle includes an intermediate power connector configured for transmitting power between a bicycle component and a power source positioned remote from the bicycle component. The intermediate power connector has a coupling portion configured for removable attachment to a connecting portion of the bicycle component. The bicycle component can also include a battery having a battery coupling portion configured for removable attachment to the connecting portion of the bicycle component. The battery and the intermediate power connector can be selectively attachable to the bicycle component to provide power thereto.

A charging base, including a charging circuit, a power supply circuit and a control unit; where the control unit is electrically connected to the charging circuit and the power supply circuit; when a charging voltage or a charging current of the charging circuit exceeds a preset threshold, the control unit controls a connecting line on the charging base to connect to a ground to form a short circuit and be disconnected from an external charging power supply, and controls a charging mode of the charging circuit to switch to a power supply mode of the power supply circuit for supplying power to a safety reminder unit provided on the charging base. The solution in the embodiments can turn off the power output in time and provide a safety alarm when the hardware circuit of the charger fails.

A power source switching system, a power supply circuit switching method and an electric vehicle. The power source switching system includes a first power source unit, a second power source unit, and a system switching control unit, the system switching control unit electrically connected to the first power source unit and the second power source unit, where the system switching control unit controls the first power source unit and the second power source unit to be connected in series or in parallel, and controls switching between the series connection of the first power source unit and the second power source unit and the parallel connection of the first power source unit and the second power source unit, implementing a charging and discharging process of the first power source unit and the second power source unit.

A bicycle information prompting method, a device, a server, and a user terminal are disclosed. The method comprises obtaining current power information of a target bicycle and sending the target bicycle to a user terminal associated with the target bicycle according to the current power information, so that the user terminal displays prompt information associated with the target bicycle.

A drive system for a side mounted cycle wheel, comprising a wheel hub for mounting the side mounted cycle wheel; a motor drive for driving the side mounted cycle wheel, the motor drive comprising an electric motor and a planetary gear reduction assembly positioned at least partially within the wheel hub and comprising one or more planetary gears; and, a rotary wheel hub bearing rotatably coupling the wheel hub to the motor drive, wherein the rotary wheel hub bearing is positioned laterally between the electric motor and the planetary gears.

A bicycle with an electric pedal assist motor capable of driving a chainring independent of cranks includes wheel speed sensors and crank cadence sensors. The wheel speed sensors and the crank cadence sensors measure wheel speed and crank cadence, respectively, and provide the measured wheel speed and crank cadence to controller of the bicycle. The controller activates motor overdrive based on the measured wheel speed and/or the measured crank cadence.

Systems and methods may coordinate and execute bidirectional energy transfer events between electrified vehicles and one or more participating electrified recreational vehicles. The proposed systems and methods may be configured to provide charging alert notifications from the electrified vehicle to the one or more electrified recreational vehicles during group off-roading events. The charging alert notifications indicate the need for the one or more electrified recreational vehicles to return to the electrified vehicle for charging during the off-roading event in order to avoid a no start/stranded condition.

A connector unit for a vehicle includes a connection connector to connect an external connector, and a support member to support the connection connector. The support member includes a cover attachment part attached to a vehicle cover, and a connector support to support the connection connector.
