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.

Herein is disclosed a straddle-ridden vehicle frame stiffener comprising a support structure for stiffening the straddle-ridden vehicle frame, the support structure comprising a first side; and a second side, adjacent to the first side; a first mounting element for removably mounting the support structure to the straddle-ridden vehicle frame, the first mounting element being attached to the first side; a second mounting element for removably mounting the support structure to the straddle-ridden vehicle frame, the second mounting element being attached to the second side; and wherein the first side and the second side are rigidly connected to one another.

A three-wheeled electric vehicle in accordance with EU vehicle classification L2e-U, which has two electric-motor-driven rear wheels, each of which is driven by one wheel-hub motor. A hydraulically actuatable rear-wheel disc-brake system is mounted on each rear wheel which brake system is also fitted with an integrated electromechanical parking brake, the activation of which shifts each rear wheel into a parking-brake mode in which wheel rotation is prevented. In a rear portion, the vehicle body forms a support structure on which an optionally present, exchangeable transport container can be supported and secured with the aid of a quick-release fastening system. The quick-release fastening system includes one or more connection device(s), wherein each connection device includes a bar that protrudes from a bottom wall of the transport container; and a locking device, which is permanently attached to the support structure, is fitted with a movable blocking element.

A novel bicycle frameset created from a novel frame assembly and a novel fork assembly, where the components of the frame are joined together via the friction stir welding of the tubular components to partial bracket members and where the joining of the partial bracket members via friction stir welding rigidly connects the tubular components to create the frame, and where the components of the fork are joined together via friction stir welding of tubular components to a fork crown, and where the fork and frame combine form the frameset.

A superefficient box beam bicycle structure (SBBBS) having a box section, a right triangular section and a left triangular section. The right and left triangular sections are either integral with the box structure, or the triangular sections are attached to the box structure by riveting, bonding or welding. The box structure is preferably made of a sheet material and the parts that comprise the box structure are attached together by riveting, bonding or welding. The SBBBS interfaces with conventional bicycle components to function as a lightweight, strong bicycle frame. Additionally, the SBBBS can be manufactured as a one-piece design, or can utilize a hybrid construction design with an internal structure and reinforcing members at areas of high stress.

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.

A vehicle includes left and right main frames that may have their front ends connected to a head pipe, and may be disposed such that the distance between the left and right main frames is progressively greater in a rearward direction. The left and right main frames may be connected to each other by an upper plate-like member, and the upper plate-like member may have a front edge spaced rearwardly from the head pipe and have left and right ends welded respectively to the left and right main frames.
