What is provided is a cargo bicycle apparatus and a kit for converting an existing bicycle into a cargo bicycle. The cargo bicycle apparatus comprises a cargo attachment that easily attaches and detaches from an existing bicycle to make the existing bicycle more utilitarian and functional. The cargo attachment connects with the existing bicycle in a way that prevents damage or permanent modification to the existing bicycle. Since no specialized tools or mechanical skills are required in the assembly of the cargo bicycle apparatus, the cargo attachment provides the operator with greater convenience and flexibility for converting an existing bicycle into a cargo bicycle apparatus. In addition, the cargo attachment is configured to automatically adjust to the geometry of nearly all existing bicycles without having to modify the geometry of the cargo attachment to match the geometry of a particular bicycle.

Safe, three-wheeled tilting scooter or motorcycle frames with two front steerable, non-tilting wheels are described herein, as well as three-wheeled tilting vehicles with various propulsion systems mounted on such frames are also disclosed. Said vehicles are preferably non-polluting, such as electric or fueled by hydrogen.

A variety of scooters are disclosed. In some embodiments, a scooter can include a pivot assembly that allows the scooter to move between a folded and unfolded configuration. The pivot assembly can include a knob that frees a pin from a bracket to allow the scooter to fold. Turing the knob increases compressive forces on elements of the pivot assembly to reduce rattling noise and wobbling movement when the scooter is in use. Some embodiments of the scooter can include a center stand that can be deployed from either side of the scooter deck to stabilize the scooter when the scooter is stationary. Certain embodiments have an ergonomic handgrip.

A bicycle accessory fastening structure is mainly applied to fasten a bicycle accessory on a bicycle. In the bicycle accessory fastening structure, recessed grooves formed on the bicycle and stabilizing blocks disposed on a mounting part are assembled with each other, so that the mounting part is stably on the bicycle and not easy to loosen, and a bicycle accessory can be mounted on the mounting part. The structure increases the stability of the combination of the bicycle accessory and the bicycle to extend a service life. Compared with the conventional technology, the bicycle accessory fastening structure can more stably assemble the bicycle accessory with the bicycle, and the assembling difficulty is still low, so that it is more applicable for a user to mount an accessory on a bicycle.

A center mounted kickstand for a two-wheeled vehicle with a swing arm rear suspension includes a rotatable apparatus, and a pivot axle. The rotatable apparatus is mounted onto a mainframe of the two-wheeled vehicle via the pivot axle, and the pivot axle is mounted transversely to a longitudinal plane of the two-wheeled and connects the swing arm to the two-wheeled vehicle. The rotatable apparatus is constructed to slide in both directions transverse the longitudinal plane of the two-wheeled vehicle on the pivot axle.

A vehicle body frame includes a head section that rotatably supports a steering shaft, and main frames extending from the head section toward a rear side of a vehicle body. A cross section of the main frame in a direction crossing a vehicle body forward/rearward direction is formed in a substantially rectangular shape having a vertical width larger than a lateral width. A carbon fiber reinforced resin in which carbon fibers are oriented uniformly in the vehicle body forward/rearward direction is installed on at least one of upper surfaces and lower surfaces of the main frames.

Provided is a traveling apparatus including at least, with respect to a traveling direction, a front wheel and a rear wheel and on which a user rides when travelling. The traveling apparatus includes a front wheel supporting member configured to rotatably support the front wheel, a rear wheel supporting member configured to rotatably support the rear wheel, an adjusting mechanism configured to adjust a wheel base length between the front wheel and the rear wheel by changing a relative position of the front wheel supporting member and the rear wheel supporting member, and a driving unit configured to drive at least one of the front wheel and rear wheel. The wheel base length adjusted by the adjusting mechanism is associated with a speed of the traveling apparatus achieved by driving the driving unit in such a way that the longer the wheel base length, the greater the speed becomes.
