A press-fit device for bicycle stein comprises a main body and two press-fit sets. The main body has a front-fork hole and a handlebar hole arranged at two ends thereof respectively. The front-fork hole and the handlebar hole have a receiving groove respectively for fluidly communicating therewith. Each press-fit set includes a driving block which has a first inclined guiding surface and a through hole with inner threads for passing through the first inclined guiding surface. A guiding block has a second inclined guiding surface and a guiding hole for passing through the second inclined guiding surface. The first and the second inclined guiding surfaces are respectively formed a tapered side and a divergent side. A press-fit block includes a trepanning hole and two inclined end surfaces. A press-fit screw is passed through the guiding hole and the trepanning hole and screwed with the inner threads.

The systems and methods described herein relate to cycling. More specifically, the systems and methods described herein relate to an integrated cycling tool. The cycling tool may be integrated into the bicycle components to reduce the external modifications to a bicycle. This may enable a cyclist to carry a tool with them without the worry of carrying the tool, or the tool falling off the bicycle. The cycling tool may comprise multiple components and may be used to fix various parts of a bicycle. The cycling tool may fit within the confines of the bicycle and provide minimal to no impact to the rider or the functionality and performance of the bicycle.

A front wheel supporting frame structure of a saddle-ride vehicle includes a main frame, upper and lower arms and a lower frame. The main frame has a front portion and a rear portion. The main frame includes an upper connection portion, a lower connection portion, and an extending portion. The extending portion extends downward. The upper arm has an upper front end portion and an upper rear end portion. The upper rear end portion is movably connected to the upper connection portion. The lower arm has a lower front end portion and a lower rear end portion. The lower rear end portion of is movably connected to the lower connection portion. The lower frame includes a bottom portion and an upright portion. The bottom portion extends in the vehicle front-rear direction. The upright portion has a top portion connected to the extending portion.

A bicycle handlebar/stem/steering tube assembly has a handle bar diameter and a steering tube diameter there-within. One or both of the steering tube and the handlebar includes one of a depression, a diameter-reduction, and a through-hole configured to mate rigidly against the other of the steering tube and the handlebar and be affixed thereto by the stem at a handlebar/steering tube interface such that a stem offset is created of a dimension that is less than either the handlebar diameter and the steering tube diameter at the handlebar/steering tube interface.

This disclosure is directed to devices and techniques for improved handlebar risers. According to various aspects of this disclosure, a handlebar riser includes a first component and a second component. The first component includes a first steering column mounting channel, and a first handlebar mounting channel. The second component includes a second steering column mounting channel, and a second handlebar mounting channel. The first component and second component are sized, shaped, and arranged such that when respective abutment surfaces of the first and second components are placed together, the first and second steering column mounting channel form a first channel that substantially surrounds at least part of a vehicle steering column, and the first and second handlebar mounting channel forms a second channel that substantially surrounds at least part of a vehicle handlebar. The first and second components are mechanically coupleable to one another.

The disclosure discloses a concealed bicycle lock system and a setup method thereof. The lock system of the disclosure includes a lock with an upper shaft and a lower shaft. The upper shaft is configured to link and move with a handlebar via a stem; the lower shaft is configured to link and move with a front wheel by embedding the lower shaft into a fork tube. When the lock is in a locked mode, the upper shaft and the lower shaft are not linked to move together. In contrast, the upper shaft and the lower shaft are linked to move together in an unlocked mode. A user may set up the lock without performing destructive modification to the bicycle.
