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.

A method of manufacturing a frame of a bike having a front wheel, a rear wheel, a saddle, a fork, and a bottom bracket includes the steps of providing a sheet-shaped element, cutting the sheet-shaped element along at least a predetermined shape to form at least one shaped sheet-shaped element, and bending of the shaped sheet-shaped element around at least one bending line to produce a bent sheet-shaped element, which defines a frame. The sheet-shaped element has a pair of substantially flat portions with an edge in correspondence of the at least one bending line, the portions of such pair being reciprocally faced and spaced apart at a predetermined distance.

A foldable electric scooter and a manufacture method of the same. The foldable electric scooter includes a main body assembly, a front fork assembly located at the front end of the main body assembly, a rear fork assembly located at the rear end of the main body assembly, a telescoping plate assembly located on top of the front fork assembly and a handlebar assembly located on top of the telescoping plate assembly. The foldable electric scooter has a double headset design that increases a rake angle for more steering stability while still keeping the steering upright for an upright holding of the handlebars. The foldable electric scooter is manufactured by stamping of flat plate material.

A manufacturing method of a bicycle unit has the following steps. In a pressing step: press metal sheets to form casing parts being overlappable. In an abutting step: abut the casing parts to form an abutting line. In a connecting step: connecting the two casing parts along the abutting line to form a motor mount prestructure having side plates and a motor-installation space formed therebetween. A prestructure of a bicycle frame is thereby made. In a motor mount forming step: cut the two side plates of the motor mount prestructure in compliance with a pre-determined motor system so as to form a bicycle frame unit with a motor mount.

A motorcycle, or saddle type vehicle, is disclosed that may have at least one seat and at least two wheels, at least one hub electric motor. A large dry storage compartment may be positioned between the rider and steering mount. A rechargeable battery and battery management system may be located below the storage compartment in a battery housing, where the battery housing may be a structural component of the chassis. A rear electronics housing may be attached to and located behind the battery housing, and may contain major electrical components such as electric motor controller and contactors. Two structural members, or frame side rails, may form sides of the storage compartment and extend between the electronics housing and steering mount. The electronics housing may also connect to the battery housing such that the battery housing reinforces and strengthens the chassis, or structural frame.
