A bike frame includes including a seat tube (10) for receiving a seatpost (2), a front portion comprising a top tube (13) connecting the seat tube (10) to a head tube (16), the seat tube (10), the top tube (13). The head tube (16) extends in a plane of symmetry of the bike frame (1). A rear portion has two chain stays (11a, 11b) and two seat stays (12a, 12b) arranged symmetrically relative to the plane of symmetry of the bike frame (1). The two seat stays (12a, 12b) are independent of each other and the two seat stays (12a, 12b) have a preform that is curved along at least one arc in a plane passing through the two seat stays, so as to enable the two seat stays to move away from or closer to each other under the action of a vertical load.

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.

A bicycle comprising a frame; a handlebar assembly attached to an upper steering tube of the frame in such a way that at least the relative rotation between the two with respect to an upper axis is allowed, but the relative displacements between both in the directions perpendicular to the upper axis are restricted; a fork attached to a lower steering tube of the frame so that it has the same degrees of freedom relative to the lower axis between the fork and the lower steering tube as the degrees of freedom relative to the upper axis between the handlebar assembly and the upper steering tube; and a means for rotation transmission for transmitting at least partially a rotation of the handlebar assembly with respect to the upper tube into a rotation of the fork with respect to the lower steering tube.

The present invention relates to a bicycle with light system. The bicycle includes a tube assembly including a frame with mutually fixed tube elements with a tube wall and movable tube elements, such as a steering pin and a handlebar, a light generation subsystem including at least one independently controllable light source for generation of light, a light control for controlling the light generation subsystem for providing at least one light effect, and a light guiding subsystem for guiding light over a part of the path between the at least one light source and the surroundings of the bicycle. The at least one light source is arranged in at least one of the at least one tube element. The bicycle includes the at least one opening in at least one tube element for passing the light through the tube wall. The light guiding subsystem provides a guiding from the inside of the respective at least one tube element to the outside of the at least one tube element of the frame.

The invention relates to a bicycle frame (1) with a remote-controlled shock absorber (2) connected to the frame (1). The shock absorber (2) comprises two dials (3, 4) for adjusting the compression and rebound. The frame (1) is characterised in that it comprises a depression (9; 25) communicated with the outside of the frame (1) and provided with a window (12; 28) that communicates the depression (9; 25) with an inner part (8b; 18b) of the frame (1). An actuator element (7) for adjusting the compression dial (3) extends from the outside of the frame (1) towards the window (12; 28) passing through the inner part (8b; 18b) of the frame (1). The invention improves the integration of the rear suspension of the bicycle while simultaneously allows for easy adjustment of the compression dial (3) and the rebound dial (4).

A bicycle frame includes a front frame assembly and a rear frame assembly pivotably connected to the front frame assembly. The front frame assembly includes a bottom bracket shell, a seat tube extending from the bottom bracket shell toward a saddle support, and a forward shock attachment point statically located on the seat tube between the bottom bracket shell and the saddle support. The rear frame assembly includes a chain stay fork including a chain stay yoke. A chain stay extends from the chain stay yoke to a rear wheel forkend. The chain stay fork includes a rearward shock attachment point statically located on the chain stay yoke. The forward shock attachment point and the rearward shock attachment point cooperate to position a suspension shock between the front frame assembly and the rear frame assembly behind the seat tube.

A method for forming a bicycle frame component made of thermoplastic composite laminates has: a shell forming step: manufacturing multiple shells by compression molding; an overlapping step: overlapping two corresponding connecting margins of each two of the multiple shells to form an overlapping section of the two of the multiple shells and deploying a supporting unit within the multiple shells for supporting; a hot compressing connection step: heating and compressing the multiple shells to diffuse polymers of the multiple shells and to turn the multiple overlapping sections into multiple fusion areas for connection; a supporting unit removal step: removing the supporting unit disposed within the bicycle frame component.

A bicycle carrier for the transport of small animals is provided. The carrier includes a platform member coupleable to a top tube of a bicycle frame and a brace member coupleable to handlebars of the bicycle. The platform member includes a base member, a plurality of side members, and a coupling member. The side members extend from one or more longitudinal edges of the base member so as to define a pod. The coupling member extends from the base member and couples the platform member to a seat post of the bicycle. The brace member includes at least one spring and a bumper member. The at least one spring may extend perpendicularly from the handlebars. The bumper member may be coupled to a distal end of the at least one spring. The brace member may assist in the positioning of the animal during transport, including for example, over uneven terrain.

A foot and hand pedaled bicycle assembly that facilitates a full body working during riding includes a bicycle that has a front wheel, a rear wheel and a frame. The frame has a top member and a lower member that each pivotally extends between a seat post and a handlebar fork. The handlebar fork is urgeable toward or away from the seat post. A pair of pedals is provided and each of the pedals is rotatably coupled to the frame for rotating the rear wheel. A pair of hand cranks is provided and each of the hand cranks is coupled to the handlebar fork for steering the bicycle. Moreover, each of the hand cranks is in mechanical communication with the front wheel for rotating the front wheel when the hand cranks are cranked.
