A component is provided for a human-powered vehicle. The component includes a component body, a single substrate, a resistor, an electric wire, a signal processing unit, a signal output, and an electric power input. The single substrate is provided on the component body. The resistor is formed on the single substrate and forms a strain gauge with part of the single substrate. The electric wire is formed on the single substrate and electrically connected to the resistor. The signal processing unit is formed or directly mounted on the single substrate and electrically connected to the electric wire. The signal output outputs a signal from the signal processing unit. The electric power input is electrically connected to the signal processing unit and supplied with electric power from a power supply provided on at least one of the human-powered vehicle and the component body.

[Problem] To provide a vehicle notification device that allows others to easily recognize the vehicle. [Solution] A vehicle notification device comprises a base portion, an attaching portion that is provided on the base portion and that can be attached to or detached from a rotating body of a vehicle that is configured to be run by a manual drive force, a wireless transmitter configured to transmit a wireless signal that notifies the presence of itself to an external device that is external to the vehicle, and a power generator that generates electric power supplied to the wireless transmitter.

A safety system comprising: a safety apparatus adapted to be mounted at the rear of a bicycle and comprising a processor, a motion sensor, a threat sensing device and a user alert device, all coupled to the processor,
wherein the processor is adapted to: control the driver alert device based on a threat position value and/or the threat speed value; control the user alert device based on at least one of a motion-based value, an ambient light-based value, the threat position value and the threat speed value. It is also claimed the safety apparatus and a collaborative safety system comprising a plurality of safety systems, each being coupled to a communication device through which the processor is further adapted to control the driver alert device and/or the user alert device of the others of the plurality in response to the sensing of a threat.

Position indicating devices, systems and methods useable for signaling the positions of pedestrians or vehicles.

The present disclosure provides a bicycle alarm device, including a main body and a connection mechanism connected with a bicycle. The main body comprises controller. The controller includes an upper cover and a lower cover connected with the upper cover. A first waterproof rubber ring is positioned between the upper cover and the lower cover. The main body also includes a battery compartment. One end of the battery compartment is connected with the controller, and the other end is connected with the connection mechanism. The battery compartment includes a compartment body and a compartment cover. A second waterproof rubber ring is positioned between the compartment body and the compartment cover. The present disclosure has good waterproof effect, and can effectively protect the controller and electrical parts in the battery compartment.

Bicycle collision systems, apparatus, and methods may include, or use, one or more various sensing apparatus to detect vehicles or other objects that may collide, or potentially collide, with a bicycle. The sensing apparatus may include at least one of side sensing apparatus, rear sensing apparatus, and front sensing apparatus. Further, alert apparatus may be used to alert not only the cyclist but also the driver of a vehicle of an imminent collision.

The field of the invention relates to bicycle systems, especially to bicycle systems adapted for use with smartphones, to smartphones configured for use with bicycle systems, and to methods and to computer software for use with such bicycle systems or smartphones, and to servers configured to communicate with such bicycle systems or smartphones. According to a first aspect of the invention, there is provided a bicycle system including a bicycle, the bicycle system including a processor integral to the bicycle, the bicycle system further including a battery integral to the bicycle, wherein the processor is powerable by the battery, the bicycle system including a smartphone holder configurable to receive a smartphone and to connect the smartphone to the processor, wherein in use the smartphone holder is attachable to, and detachable from, the smartphone. Advantages include that the smartphone can be charged by the battery, the smartphone can communicate with the processor so as to receive various information such as maintenance-related information of the bicycle system, the bicycle system can investigate the smartphone identity to check for unauthorized use of the bicycle system, the smartphone is held during bicycle system travel which reduces the risk of damage to the smartphone, and the bicycle system shape is more aerodynamic than that of a bicycle to which a processor and/or a battery has merely been bolted-on.

A smart safety device for a bicycle or scooter is disclosed. The smart safety device includes a pair of handlebar grips configured to be removably coupled to a handlebar of the bicycle or scooter. Each handlebar grip includes at least one object detection sensor to detect traffic in the vicinity of the handlebar, and at least one vibrator configured to vibrate based on input from the at least one object detection sensor. Moreover, the smart safety device includes a user interface mounted substantially centrally to the handlebar and including at least one detector to detect traffic in front of the bicycle or scooter. The user interface also includes at least one indicator configured to indicate a presence of an object in front of the bicycle or scooter based on input from the at least one detector.
