A bicycle frame assembly includes a first trimmed panel having a planar configuration defining a first plane and a second trimmed panel having a planar configuration defining a second plane. The first and second trimmed panels have a predetermined shape configuration and are positioned such that the first plane and second plane intersect. The bicycle frame assembly includes trimmed panels that include planar panels that define two, four, or even six planes.

Embodiments of the present invention are directed to a bicycle headset assembly. More specifically, such embodiments comprise a headset assembly cap having a cover that is mountable thereon. The cover serves at least two purposes. One purpose is to conceal a load imparting fastener receiving portion of the headset assembly cap. Another purpose is to provide a contiguous surface on which graphics can be provided.

A two-wheeled vehicle includes a frame having a front frame portion, a mid-frame portion, and a rear frame portion. The mid-frame portion is coupled to the rear frame portion and the front frame portion. The vehicle further includes a plurality of ground-engaging members for supporting the frame. The front frame portion is removably coupled to the mid-frame portion with a plurality of frame members extending between the front frame portion and the mid-frame portion.

An apparatus, system, and method are disclosed for adjusting a height of a handlebar. The apparatus includes a steering tube coupling member, a handlebar coupling member, at least one connector and a height adjusting member. The at least one connector adjustably couples the steering tube coupling member to the handlebar coupling member. The height adjusting member is coupled to at least one of the steering tube coupling member, the handle bar coupling member, and the at least one connector. Actuation of the height adjusting member selectively adjusts a height of the handlebar coupling member relative to a height of the steering tube coupling member to selectively adjust a height of the handlebars.

A handlebar stem, in particular for racing bicycle handlebars, comprises a main element which is connected to a handlebar at a front end. The main element is connected to the handlebar stem tube in the area of a rear end. The handlebar stem tube is connectible to a steerer tube such that it is bendable in the longitudinal direction to improve riding comfort.

In a body frame, a pair of left and right main frames extend downward to the rear from the upper portion of a head pipe and a down frame extends downward to the rear from the lower portion of the head pipe, a gusset is provided in the body frame, the gusset being joined to the head pipe, and the gusset includes a center wall portion and lower extension portions, the center wall portion being disposed between inner side wall portions of the left and right main frames, the lower extension portions extending downward from the center wall portion and being joined to outer side surfaces of the down frame.
