A folded bicycle frame comprising a single and continuous sheet of metal is disclosed. The bicycle frame is formed by cutting the sheet of metal to form a boundary, hydroforming the sheet of metal to create a profile comprising indentations and protrusions along the sheet of metal, and then folding the molded sheet essentially along its axis of symmetry, such that the symmetrical parts of the sheet are positioned next to each other to form the frame with a hollow interior. Holes are precut in the frame so that other bicycle parts may be attached to the frame. The frame is produced without the need for any welding or connecting of individual parts. Thus, it is stronger than conventional bicycle frames which are weaker at such welded connections of their parts. A method for making the folded frame is also disclosed.

The described bicycle has a frame made of a composite material and defining a monocoque shell which is monolithic, entirely formed of the composite material, and includes: a rear upper portion, a head tube portion, and a rear mounting portion; and first and second side panels each extending between, and integrally formed with, at least the head tube portion at a forward end and the rear upper portion and the rear mounting portion at a rearward end. The first and second side panels are integrally interconnected along their respective top and bottom edges to form a substantially hollow shell structure at least partially enclosing a shell cavity defined between the laterally spaced apart first and second side panels. The hollow shell structure defines a rear opening between the rear upper portion and the rear mounting portion that communicates with the shell cavity.

An axle mounting system includes a pair of axle supports each to be positioned within a respective one of a pair of openings and each having an axle support hole therethrough, a pair of positioning chips each to be positioned within a respective one of the openings and each having a hole therethrough to receive a respective one of the axle supports, and a pair of fixing nuts each to secure the respective one of the axle supports within the respective one of the openings.

In an aspect, an electrical vehicle for traveling in a forward direction has two wheels on opposing side of a platform without a steering column. A motor and a battery are adapted to drive one wheel and controlled via a fold-out foot control. The steering wheel is controlled via a fold-out foot control. Both the driving wheel and the steering can also be controlled remotely by radio, smartphone app or the like. The two fold-out foot controls are integrated into the general shape of the platform when not in use. The vehicle is equipped with lateral balancing means and connected to a network, which enables it to be driven autonomously.

A two wheeled vehicle is propelled by the feet of a rider and hand-grasped poles when pushing against the ground. A forward wheel on a forward member and a rear wheel on a rearward member align along a longitudinal axis. The forward member rotates about a vertical steering axis. A saddle supports the rider. A torso brace allows the rider to balance and steer the device.

A bicycle fork having a steerer tube assembly having top and bottom steerer tube sections wherein the length of the steerer tube assembly is adjustable by interchanging top steerer tube sections of differing lengths is described. The top and bottom steerer tube sections include one or more meshing teeth and valleys that facilitates the transfer of torque when the top and bottom steerer tube sections are joined together.
