A bicycle frame including a down tube, a saddle tube, and a top tube is disclosed. The top tube comprises a first section which, starting from the saddle tube, is oriented in an ascending orientation. Thereby, a space between the down tube, the saddle tube, and the top tube is enlarged, so that the bicycle frame can be carried on a person's shoulder in a more convenient manner.

A bicycle includes a frame having cross sectional profiles. The profiles are designed according to certain criteria to enhance bicycle performance. The profiles for multiple frame members may each fall within a range for each of aspect ratio, circumference, drag coefficient, first moment of inertia and/or second moment of inertia.

The present invention relates to a frame for a bicycle including a tube construction for providing fastening options for further parts of the vehicle, such as a steering pen, saddle pen and fastening means for a rear wheel. The tube construction includes: a top tube, substantially extending in horizontal direction; a saddle tube, downwardly extending from a tube intersection with the top tube, from a fastening to the top tube at a substantially rear side thereof; a bottom tube, extending from a tube intersection with the saddle tube at substantially an underside of the saddle tube towards a connection at the top tube forwardly arranged relative to the fastening of the settled tube to the top tube; and a head tube arranged at an angle by means of a tube intersection connected to the top tube. The bottom tube extends to a predetermined distance above the upper side of the top tube, crossing the top tube at a tube intersection, and the head tube is fastened to the bottom tube above the top tube.

A bicycle cross bar adaptor includes a first tube, a second tube and a control unit. The control unit is located between the first and second tubes. Each of the first and second tubes has a hook connected thereto. The second tube has a groove defined axially in an outer surface thereof. The control unit includes a collar in which the first and second tubes are slidably inserted with each other. A hole is defined through the wall of the collar and a block is located in the hole. A block is located in the hole and removably engaged with the groove. A lever is pivotably connected to the collar and has a cam portion to perform as a quick-release to position the block in the groove or away from the groove to adjust the second tube relative to the first sleeve.

A bicycle frame includes a tube with a hollow portion. The tube has an opening that provides access to the hollow portion, and the tube also includes one or more recessed flanges adjacent to the opening. The bicycle frame also includes a cover holder configured to mount to the one or more recessed flanges adjacent to the opening in the tube. The bicycle frame further includes an in-tube storage cover that mounts to the cover holder such that at least a portion of an exterior surface of the in-tube storage cover is flush with an outer surface of the tube. The in-tube storage cover includes a lever mounted on the exterior surface of the in-tube storage cover.

A bicycle frame includes a front triangle comprising a head tube and a bottom bracket shell, a tension bar comprising a first end and a second end, wherein the first end of the tension bar is pivotably connected to an upper portion of a telescoping seat post assembly, and a first fore pivot assembly at a first reach point. The first reach point is between a reach point of the bottom bracket shell and a reach point of the head tube. The first fore pivot assembly is pivotably connected to the second end of the tension bar. The frame further includes an aft pivot assembly at a second reach point, wherein the second reach point is closer to the reach point of the bottom bracket shell than the first reach point, and wherein the aft pivot assembly is pivotably connected to a lower portion of the telescoping seat post assembly.

The present disclosure relates to a separable bicycle and a separable bicycle frame, which are capable of facilitating transport and storage, and each of the separable bicycle and the separable bicycle frame includes a head tube capable of receiving a handle stem, a seat tube accommodating a seat post on which a seat is installed, a top frame connecting an upper portion of the seat tube to the head tube, and a down frame connecting a lower portion of the seat tube to the head tube, wherein, in order for the head tube connected to a front wheel and the seat tube connected to a rear wheel to be completely separated from each other, a top fastening portion is installed in a middle of the top frame and a down fastening portion is installed in a middle of the down frame.
