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

A bicycle and method and bicycle assembly for a bicycle including a control device and at least one bicycle component whose operating state is variable during operation. An acoustic device with a sound converter is included for outputting information, controlled by the control device, on the operating state of the bicycle component by means of the acoustic device, and/or for capturing noises by means of the acoustic device and converting these to noise signals and utilizing them for controlling.

An illuminating device and a method for optimizing the light pattern are provided. The illuminating device includes a lamp case having a lighting space; a light-reflecting cup, located in the lighting space and including a light incident side, a light emergent side; a light source, located in the lighting space and corresponding to the light incident side of the light reflecting cup; and a cylindrical lens, located in the lighting space and corresponds to the light emergent side of the light reflecting cup; wherein one surface of the cylindrical lens has a plurality of convex columns extending up and down, and each convex column faces to the light emergent side; wherein, when the light source emits light, the main bright area of the light pattern reflected by the light emergent side of the light reflecting cup is wide at the top and narrow at the bottom.

The utility model discloses an improved bicycle handlebar, including a handlebar tube and a handlebar head. The handlebar head includes a curved arm and grips. The curved arm is of a structure that inclines forward relative to the handlebar tube. The grips naturally stretch along two ends of the curved arm toward the left and right sides. The handlebar tube is provided with a positioning groove and a limiting hole, a support tube is provided with a positioning protruding portion. After the handlebar tube is inserted into the support tube, the positioning protruding portion is inserted into the positioning groove to ensure that the handlebar will not rotate by itself. Screw the limit screw into the limiting hole to prevent the handlebar from being too deep to pull out. The handlebar is designed to be of a structure, which is more comfortable to use.

Embodiments of the present disclosure include a wireless remote control or remote control application for controlling the lighting of an electronic personal transportation vehicle. Embodiments can solve problems related to sharing electronic personal transportation vehicles by uniquely identifying a user, and allowing that user to control the lighting of the electronic personal transportation vehicle. In this manner, other users can control the lighting at different times, depending on the specific person that is using the electronic personal transportation vehicle at any given time.

The invention discloses a new type of bicycle capable of improving driving safety, comprising a bicycle body, assemblies of rear view mirrors are symmetrically arranged on the handlebars of the bicycle body; a brake light is arranged on the rear end of the seat of the bicycle body, turn lights are symmetrically arranged on the fixed connecting rods which connect with the frame on both sides of the seat; an illuminating light is arranged on the vertical tube of handlebar of the bicycle body, an electric horn is arranged on the upper side of the illuminating light; the application scheme is complete, simple in structure, effective in improving driving safety, and is worthy of widespread promotion.
