A bicycle includes a transmission having two switchable drives between a driver body on which rear sprockets are positioned and a wheel hub of a rear wheel. The bicycle has actuation elements for switching between drives and operating elements for operating the actuation elements. The bicycle includes only a single front sprocket. The actuation elements are embodied in an electrical version and the operating elements are electrically coupled to the actuation elements. By advantageously selecting the drives of the driver between the cassette housing and wheel hub, a front derailleur may be omitted. The driver allows operation with only little energy, since the chain need not be shifted. consequently, the actuation elements require little energy for changing the drive between the crank axle and the wheel hub of the bicycle, so that it is pre-eminently suitable for these actuation elements and their operation to be executed as an electrical version.

A bicycle power meter includes a strain gauge, a signal processing unit, a processor, and a signal transmitter. The strain gauge is disposed on at least one of an outer peripheral wall and an inner peripheral wall of a stem of a bicycle. The signal processing unit connected to the strain gauge by signal correspondingly outputs an electrical signal based on a deformation of the stem detected by the strain gauge. The processor connected to the signal processing unit by signal receives the electrical signal sent by the signal processing unit and calculates a measuring value based on the electrical signal and sends the measuring value in an output signal. The signal transmitter connected to the processor by signal receives the output signal sent by the processor and converts the output signal to a wired or wireless signal and sends the wired or wireless signal to a terminal device.

A camera housing device is provided in this disclose, including a base, a cover, a first electrical connection terminal, a first indicating light, and a second electrical connection terminal. A receiving space is defined on the base to receive a camera. The cover is positioned on the base and covers the receiving space. The first electrical connection terminal is positioned on the base. The first indicating light is positioned on the cover. The cover is capable of emitting a warning light according to a warning signal sent by the camera. The second electrical connection terminal is positioned on the cover and electronically coupled with the first electrical connection terminal. A camera equipment and a rear view system are also provided in this discloses.

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.

Provided are a detecting device, a detecting method, a generating method, and a computer-readable storage medium that allow the user to readily obtain information on the degree of wear for a worn portion in the human-powered vehicle. A detecting device includes a control unit that detects a worn portion in a human-powered vehicle as a target worn portion from a first image including at least a part of the human-powered vehicle and outputs wear information related to a degree of wear for the target worn portion.

A control data creation device is provided that has an acquisition part, a creation part and an evaluation part. The acquisition part acquires input information concerning traveling of a human-powered vehicle. The creation part creates by a learning algorithm a learning model that outputs output information concerning control of a component of the human-powered vehicle based on input information acquired by the acquisition part. The evaluation part evaluates output information output from the learning model. The creation part updates the learning model based on training data including an evaluation by the evaluation part, input information corresponding to an output of the output information and the output information.

A removable display assembly for a bicycle includes: a housing having a body that extends along a first direction from a first end to a second end, wherein the body further extends along a second direction that is transverse to the first direction, such that at least a portion of the body can be positioned through an opening in a wall of a first tube of a bicycle frame to be at least partially positioned within an internal cavity of the first tube, wherein the opening extends along the first direction from a first end to a second end, a display coupled to the body of the housing; a first transverse spring coupled to the first end of the housing; a second transverse spring coupled to the second end of the housing; and a third spring coupled to the second end of the housing.

A coordinator device for a bicycle includes a processor configured to receive a signal generated in response to user input at an input element from a controller device. The signal includes data identifying a device type and data identifying the input element. The coordinator device includes a memory configured to store the data identifying the device type and the data identifying the input element. The processor is configured to generate a notification based on the received signal, transmit the generated notification to the mobile device, and in response to the transmission of the generated notification, receive a request for data related to the received signal from the mobile device. The processor is further configured, in response to the request, to transmit the stored data to the mobile device, such that an association of the controller device with the representation of the controller device is identifiable within the GUI at the mobile device.
