A limiting structure of a bicycle includes a handlebar, a rotating member, a front fork, and a frame. The frame is provided with a mounting portion. The handlebar is partially accommodated at one end of the mounting portion, and the front fork is partially accommodated at the other end of the mounting portion. The rotating member is accommodated in the mounting portion. Two ends of the rotating member are movably connected to the front fork and the handlebar, respectively. An annular movable groove is formed between an inner wall of the mounting portion and the rotating member. The front fork is provided with a first limiting block, and the first limiting block is movably accommodated in the movable groove. The frame further includes a second limiting block, and the second limiting block is fixedly accommodated in the movable groove.

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 tilting vehicle includes a frame unit, a tilting mechanism and two front wheels. The frame unit includes a head tube extending generally along an up-down direction, and a main frame detachably connected to the head tube. The tilting mechanism includes one crossbar pivotally connected to the head tube and extending along a left-right direction, and two connecting rods extending along the up-down direction, being opposite to each other along the left-right direction, and being pivotally connected to opposite ends of the one crossbar, respectively, such that the connecting rods are movable along the up-down direction relative to the head tube. The front wheels are rotatably mounted to the connecting rods, respectively.

A method of modifying the rake angle on a motorcycle having a double wishbone front suspension. The motorcycle has a tubular steering housing connected to a non-telescoping fork assembly by a straight body steering stem. The method includes the step of replacing the straight body steering stem with a canted body steering stem. The canted body steering stem includes (i) a primary section having a steering axis corresponding to a steering axis of the motorcycle; and (ii) a secondary section having a cant axis which varies from the steering axis by between 1° and 16°.

A sprung stem for bicycles, in particular for racing bicycles and gravel bikes, for the sprung connection between the handlebar and the head tube and/or the steerer tube with improved damping is proposed, wherein a coupling apparatus for mechanical coupling of the connecting parts is provided, which coupling apparatus comprises at least one elastomer body which is mounted in such a way that it is deformed during pivoting of the static fastening device with respect to the handlebar holder, in order thus to absorb force and to damp the relative movement between the handlebar and the head tube.

Systems and methods directed to a steering column clamp for securing a steering column to a steerer tube are provided. The steering column clamp may include an internal clamp portion having longitudinal slot disposed at least partially between a first end of the internal clamp portion and a second end of the internal clamp portion. The steering column clamp may include a tightening mechanism, when engaged, causes the internal clamp portion to compress about a steerer tube placed in a first end of the internal clamp portion. The steering column claim may also include an exterior wall portion at least partially enclosing the internal clamp portion such that a hollow portion is between the internal clamp portion and an internal surface of the exterior wall portion of the steering column clamp.

An angle adaptor for an integrated system (IS) bicycle frame head tube allows a user to change the effective head tube angle, and thus the fork trail, for a bicycle.

The present invention relates to a head assembly for a bicycle including a front fork tube arranged to extend through a head tube of a frame of the bicycle and a tensioning assembly for tensioning of the headset assembly relative to the front fork tube, such as for rotation relative to the front fork tube by means of a suitable bearing. The tensioning assembly includes a tensioning member, such as a bridge or star, preferably with an inner screw thread, arranged in the front fork tube, suitable for receiving a fixation tensioner, such as a tensioning bolt, preferably with an outer screw thread, and for receiving of a tensioning force of the headset assembly, a tensioning sleeve for arranging about a length of an end of the front fork tube and for extending somewhat beyond the end of the end of the front fork tube, and a tensioning cap for applying the tension between the front fork tube and the tensioning sleeve by means of the fixation tensioner. The headset assembly is suitable for functional mounting and tensioning by means of the fixation tensioner prior to mounting of a bicycle handlebar or handlebar bend to the headset assembly.
