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.

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).

A prone bicycle comprising a frame (1), a front wheel (2), a rear wheel (3), a drive mechanism (4) for driving the rear wheel (3), and a pedal mechanism (5) for driving the drive mechanism (4), in which, the front wheel (2) and rear wheel (3) are mounted on the front portion and rear portion of the frame (1), wherein: a forearm support member (6) is mounted at the frame (1) front portion, and a dynamic knee support member (7) having synchronous movement with the pedal mechanism (5) is mounted between the pedal mechanism (5) and the frame (1). Designed with multi-point dynamic and static supports, this prone bicycle improves riding comfort and efficiency and is combined with crawling fitness function.

A rotational torque surge brake assembly mounted to a bicycle aerobar that provides an ergonomic brake design allowing riders utilizing aerobars to brake using a natural supination motion of the forearm while remaining in the tucked, aerodynamic racing position. Braking is activated by supine radial rotation of an actuating handle grip (6) mounted rotatably about a base mounting member (7) that is itself affixed to an aerobar (9) mounted on the bicycle handlebar. The bicycle's brake cable is attached to the handle grip (6) in such a manner that radial motion of the handle (6) results in axial motion of the brake cable (10), relative to the axis of the bicycle frame.

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 tricycle that allows riding in adequate conditions over any type of terrain is disclosed, the tricycle having a structural frame onto which a seat and several pedals are incorporated, equipped with a rolling assembly made up of one rear wheel and two parallel front wheels, with the front wheels incorporated into two mounting forks equipped with several respective stems projecting upwards.

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 handlebar assembly is able to attach to a bicycle. The handlebar assembly provides a higher grasping point for a bicycle operator than the original handlebar, enabling the operator to lean back and assume a recumbent posture while riding. The handlebar assembly includes and attachment member, a handlebar member, and an extension vertically separating the two components. The attachment-member is able to affix about the existing tubular handlebar of the bicycle by means of a clamp.

The invention relates to an accessory fixing module adapted to connect an accessory to a bicycle handlebar. The accessory fixing module includes a fastening member and a hanger. The fastening member has a ring part adapted to sleeve onto the bicycle handlebar, and the ring part is provided at one side thereof with a fixing portion. The hanger includes a first connector part for connection to the fixing portion, a second connector part adapted for connection to an accessory, and a bracket part linking the first connector part to the second connector part. The bracket part includes a first longitudinal frame body, a second longitudinal frame body, and a transverse frame body linking the first longitudinal frame body to the second longitudinal frame body. The first and second longitudinal frame bodies are arranged at a fixed angle with respect to the transverse frame body.

A bicycle frame set includes a front fork, a head tube, a main tube, a seat tube, and a seat stay. The front fork includes a right fork leg and a left fork leg. The front fork is rotatably coupled to the head tube. The main tube is connected to the head tube. The seat tube is connected to the main tube, the seat tube being configured to connect to a seat post. The seat stay includes a first portion connected to the seat tube at a front end of the first portion of the seat stay. When a rear wheel and a front wheel are mounted to the bicycle frame set, the first portion of the seat stay extends in a horizontal direction substantially parallel with respect to a ground plane supporting the rear wheel and the front wheel.
