An ergonomic device to provide a removable tray assembly to be attached to a bicycle via one or more means is described, wherein the removable tray assembly may comprise: a tray; an interface element that attaches the tray to a mount via a locking mechanism, such as a quarter turn locking mechanism, wherein the mount comprises a clamping mechanism to attach the mount to the bicycle. According to certain embodiments, the tray may be configured for attachment to a handlebar of a bicycle, such as a stationary bicycle, to provide a platform to hold or place one or more objects.

The invention relates to vehicles having at least one handlebar, especially to motorcycles. It turned out that during a frontal crash the handlebar of the motorcycle itself constitutes a threat for the cyclist because in case of such a frontal crash this handlebar can constitute a basically non-movable barrier for the cyclist and the risk is high that the abdomen of the cyclist hits this barrier. So, at least one weakening—or destruction device is provided. This weakening—or destruction device is able to be directly or indirectly triggered by a crash sensor system and is able to weaken or destroy the at least one handlebar or to weaken or destroy the connection of the at least one handlebar to the fork of the motorcycle when triggered.

A foldable electric scooter and a manufacture method of the same. The foldable electric scooter includes a main body assembly, a front fork assembly located at the front end of the main body assembly, a rear fork assembly located at the rear end of the main body assembly, a telescoping plate assembly located on top of the front fork assembly and a handlebar assembly located on top of the telescoping plate assembly. The foldable electric scooter has a double headset design that increases a rake angle for more steering stability while still keeping the steering upright for an upright holding of the handlebars. The foldable electric scooter is manufactured by stamping of flat plate material.

A mount for an auxiliary handlebar, the mount comprising: a stem; a fastener configured to receive the auxiliary handlebar; a clamp configured to secure the mount to a primary handlebar; and a clamp lock comprising: a linkage rotatably connected to the stem; and a cam lever rotatably connected to the linkage; wherein the clamp lock is configured to selectively lock the clamp.

A saddle-ride type vehicle is capable of achieving miniaturization of a front cowl while ensuring a flow rate of air introduction. An opening penetrating through a longitudinal direction of a vehicle is formed below the center in a height direction of a vertically long windshield. First traveling air is passed through the opening formed in the windshield. A direction of the first traveling air is then changed by a guide member, and is moved upward along a back surface of the windshield. Excessive vacuum on the back surface of the windshield is corrected. Since an opening is formed in the windshield, it is not necessary to increase a width of the front cowl, and miniaturization of the front cowl can be achieved. Since the windshield is formed as a vertically long windshield, the opening can be formed to be vertically long, and an opening area can be ensured.

A direct-drive double wing scooter includes a frame, an actuation assembly, a drive assembly, and a transmission assembly. The actuation assembly includes left and right swing wings each pivoted close to a front end of the frame through a pivot. The drive assembly includes a first turning shaft and a second turning shaft penetrating two sides of the frame. A distance between the first turning shaft and the pivot is defined as a first distance. A distance between a rear end of the right swing wing is defined as a second distance, or a distance between a rear end of the left swing wing is defined as a second distance. The first distance is in the range of 0.10-0.65 times the length of the second distance. The direct-drive double wing scooter provides a simple and reliable drive way and has transportation, amusement and fitness effects.

A replacement bicycle stem is disclosed herein. In particular, prior to operation of a bicycle in a stationary environment, the bicycle stem, if present, is removed and replaced with the replacement bicycle stem disclosed herein. The replacement bicycle stem is intended to rotate or turn with the handlebars, but independent of the steer tube and front wheel. More specifically, the replacement stem includes a main body with a mounting channel at one end and a handlebar clamp at another end. At least one bearing is disposed within a portion of the mounting channel for engagement against the steer tube. The at least one bearing allows or facilitates rotation of the stem about the steer axis independent of or substantially independent of the steer tube.

A bicycle handlebar system that ensures comfort, safety, and increased center of gravity control. An ergonomic bicycle handlebar system having a sweep angle in the range of 4 to 45 degrees, a slope angle in the range of 5 to 60 degrees or both accomplishes comfort, safety, and increased center of gravity control. The handlebar may be made of nano tube zlyte resin with graphene-impregnated carbon fibers. The interplay of sweep angle and slope angle is recognized.
