A stowable steering column for a vehicle comprising a fork steerer tube including a fork; a base coupled to the fork steerer tube; a steering tube slidably received within the base and the fork steerer tube, the steering tube including an upper terminal end and a lower portion; a handlebar assembly coupled to the upper terminal end of the steering tube. The maximum effective length of the steering tube is greater than the effective length of the fork steerer tube and base and the steering tube is slidable into different axial positions relative to the base and fork steerer tube to facilitate different handle bar heights for riding and the steering tube is slidable downwards so that the handlebar assembly approaches the base and substantially all of the steering tube is stowed within or below the fork steerer tube for at least one of transport and storage.

A universal electric vehicle frame configured to be exchangeably coupled to a plurality of different types of sets of wheel assemblies to selectively form a plurality of different types of electric vehicles including an electric scooter, an electric skateboard, and an electric bicycle. The universal electric vehicle frame includes an encasement for housing one or more batteries to power the electric vehicles. At least one of the wheel assemblies includes an electric motor powered by the batteries, and configured to turn a wheel of the wheel assemblies.

A fluid reservoir for a cycle frame, the cycle frame including a top tube extending from a head end to a seat mounting, the fluid reservoir including a body defining a cavity for containing a fluid, the body positioned in abutment with at least a part of the top tube in use, and wherein the body is shaped so that the fluid reservoir and the at least a part of the top tube cooperate to define an aerodynamic profile.

A bicycle frame assembly including a seat tube having first and second end portions (wherein the seat tube second end portion includes a bend and terminates in a first open end facing a first direction), a down tube having first and second end portions (wherein the down tube first end portion is mounted to the seat tube first end portion, and the down tube second end portion includes a bend and terminates in a second open end facing a second direction opposite to the first direction), and a top tube having first and second end portions (wherein the top tube first end portion is mounted to the seat tube second end portion and terminates in a third open end facing the first direction, and the top tube second end portion is mounted to the down tube second end portion and terminates in a fourth open end facing the second direction).

A box beam bicycle structure (BBBS) 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 BBBS interfaces with bicycle components to function as a lightweight, strong bicycle frame. Additionally, the BBBS 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.

A two-wheeler vehicle comprising a steerable front wheel of at least 16 (d.sub.f), a fixed back wheel smaller than or equal (d.sub.b) to d.sub.f. A distance between the back wheel ground contact point and the front wheel contact point is smaller than or equal to (12+(d.sub.fd.sub.b). A steering mechanism defines a steering axis ground contact point. A trail distance between the steering axis ground contact point and the front wheel ground contact point is between 5% and 10% of the d.sub.f. The steering mechanism comprises a fork, a yoke and a handlebar. A frame interconnects the yoke and the center of the back wheel and comprises a standing mechanism providing at least one footboard, below the back wheel center, extending laterally from the frame.
