An aerodynamic assembly for bike handlebars, includes two distinct extension devices (4a, 4b), each of the two extension devices (4a, 4b) having: a first armrest-forming part (5a, 5b), able to be fastened on a transverse bar of a bike handlebars (1) while extending longitudinally forwards and including a longitudinal extension (6a, 6b) forming a free end portion. An upper surface of the first part with its longitudinal extension forming a receiving surface for a forearm part of a cyclist. A second extension-forming part (8a, 8b), able to be fastened, in a removable manner and in the extension of the first part (5a, 5b), to the free end portion, the second extension-forming part (8a, 8b) being able to slide longitudinally relative to said longitudinal extension (6a, 6b) so as to allow an adjustment of a distance separating a free end of the second extension-forming part (8a, 8b) from the first armrest-forming part (5a, 5b).

An auxiliary handle bar system includes a pair of handle bars, each secured beneath a bicycle handle bar.

Embodiments described herein provide container mounts for mounting water bottles, bento boxes, tool holders or other containers in an aerodynamic position. According to one embodiment, the container mount can include an attachment member to attach to the bicycle frame or aerobars. One or more container support members are coupled to the attachment member in a fixed orientation or in a manner that allows the position of the support member to be adjusted. The container mounts can be configured so that the container is positioned within the aerodynamic profile of the rider's torso between the rider's arms (when viewed from the front) and is accessible by the rider while the rider maintains aerodynamic form.

An operating device comprises a base member, an operating member, a user operating portion, and a restriction member. The base member includes a first end portion, a second end portion, and a grip portion. The first end portion is configured to be coupled to a handlebar. The second end portion is opposite to the first end portion. The grip portion is provided between the first end portion and the second end portion. The operating member is pivotally coupled to the base member about a pivot axis. The user operating portion is configured to receive a user input and provided at the second end portion of the base member. The restriction member is at least partly provided, as viewed along the pivot axis, between the user operating portion and the first end portion of the base member to restrict unintentional access to the user operating portion.

An operating device comprises a base member and an operating member. The base member is configured to be mounted to one of a dropdown portion and a bar end portion of a handlebar. The base member includes a cylinder bore and a reservoir bore. The cylinder bore has a cylinder center axis. The reservoir bore has a reservoir center axis. The operating member is pivotally coupled to the base member about a pivot axis. The cylinder center axis is offset from the reservoir center axis in a pivot axis direction parallel to the pivot axis and in a perpendicular direction perpendicular to both the pivot axis and the cylinder center axis.

An operating device comprises a base member and an operating member. The base member includes a first end portion, a second end portion, and a grip portion. The first end portion is configured to be coupled to a handlebar. The second end portion is opposite to the first end portion. The grip portion is provided between the first end portion and the second end portion. The operating member is pivotally coupled to the base member about a pivot axis. The base member includes a first lateral surface, a second lateral surface, and a first positioning portion. The second lateral surface is provided on a reverse side of the first lateral surface in a pivot axis direction parallel to the pivot axis. The first positioning portion is provided on the first lateral surface. The first positioning portion is configured to position a rider's finger.

A dual powered propulsion system for use with a human powered vehicle is provided. The system includes a connecting rod with a front end operatively coupled to yoke-connected forearm bars. The system also includes a splitter coupled to a rear end of the connecting rod, wherein the splitter is coupled to a first rack and a second rack that operate with a first and second pinion gear to turn a crank axle. This system supplies rotational power to the crank axle in a single rotational direction as the connecting rod is oscillated up and down and back and forth. Even though a solid connecting rod is used to transfer power from the oscillating forearm bars to the crank axle, the vehicle is steerable to the right or left as a result of the use of a carriage, on rollers, and a turning track operatively connected to the forearm bars.

Tri-Power Exercising device allows a rider to simultaneously, or on demand, exercise virtually all muscle groups in his lower and upper body. The device includes a bicycle frame, pedals, forearm bars, sliding seat, computer and electronic display recommending energy modulation amounts from various muscle groups to optimize physical performance on any given trek. Because riders can exercise virtually all muscle groups at once, they reduce their exercising time, continuously builds muscle tissue throughout their whole body, and exercises their cardiovascular and respiratory systems completely. Riders operate the device by rotating legs on the pedals, rotationally oscillating the forearm bars up and down with their arms and shoulders, and then use core muscles to pull and push the seat back and forth on the slider. Inverted racks, pinion gears, and one-way bearings turn this linear power from the oscillating forearm bars and sliding seat into torque that rotates the crank axle.

A bicycle handlebar assembly comprises a base bar, a v-shaped stem selectively removable from the base bar, and a bicycle fork assembly. Control cables from the bicycle may be routed from the base bar into hollow diverging stem members of the v-shaped stem. The bicycle fork assembly comprises an external-steerer fork having a load-bearing member and a preload tensioning rod. The preload tensioning rod fits within a head tube of the bicycle, and a hollow space around the preload tensioning rod accommodates control cables passing from the v-shaped stem into a hollow portion of the bicycle frame. The v-shaped stem is secured against the base bar by a pair of nut plates. In some examples, an engagement portion of an accessory such as an aerobar extension assembly is configured to secure the v-shaped stem and an aerobar extension against the base bar.

Racing bicycle, in particular for time trials, triathlons or suchlike, comprising a frame provided with a head tube, a top tube and a fork connectable on one side to the head tube and on the other side to a wheel of the bicycle; in the fork one or more apertures are made for the passage of the air, made between the external surface of the wheel and the top of the head tube; the one or more apertures are configured to allow at least part of the stream of air that hits the bicycle to pass in a central zone of the bicycle and in proximity to the frame; the top tube is positioned above the one or more apertures in order to leave the central zone free, and therefore not interfere with the stream of air passing in the central zone and below the top tube.
