A bike having an energy recovery device includes a driving wheel that is coupled to a rear wheel driving shaft pulley of the bike and rotates with the rear wheel of the bike. When a wire is pulled by the bike rider, an outer peripheral surface of a rotating wheel contacts an outer peripheral surface of the driving wheel and rotates together by means of friction with the driving wheel. When the wire pulling force is released, contact with the driving wheel is released. A piston moves in the forward/backward direction inside a cylinder of a compressor. During operation, air is compressed by the movement of the piston, exits through an exhaust opening formed on the rear portion of the cylinder, and is stored in an air tank through an air hose.

In an aspect, a pivot joint for a collapsing foot-deck-based vehicle is described, comprising a foot deck, at least two wheels coupled to the foot deck, and a handlebar assembly coupled to the foot deck via a locking pivot joint, also referred to as a locking swivel joint, the handlebar assembly comprising at least one handle, the locking pivot joint having a pivot axis that is generally unparallel with a horizontal plane defined by the lowermost surfaces of the at least two wheels, the handlebar assembly being selectively pivotable via the locking pivot joint between a riding configuration in which the handle is generally distal from the foot deck and a collapsed configuration in which the handle is generally proximal to the foot deck.

A tricycle is provided having a front frame assembly, a rear frame assembly pivotally connected to the front frame assembly, and a release assembly connected to both the front frame assembly and the rear frame assembly to secure the rear frame assembly to the front frame assembly in a use position and alternately in a storage position. The release assembly is moveable to allow for transitioning the rear frame assembly to the storage position from the use position. A foot rest is connected to the tricycle and is also moveable between a use position and a storage position. The tricycle also has a restraint hoop and a canopy, and quick release mechanisms to removably secure the restraint hoop and the canopy to the tricycle.

An extensible roof for vehicles such as scooter-type motorcycles is provided. The extensible roof protects the passengers of the vehicle from the inclement climate and is able to be retreated in the front part of the vehicle and to be opened in the case of rain, snow or at the passenger's will, covering him/them totally from said inclement climate by means of the surface formed by different plates of roof linked to each other through a sliding system. The proposed roof is of the type comprising a mobile transparent covering panel, slidable in an upward and downward direction characterized in that when folded, the higher border of said at least one covering panel is below the handlebar of the motorcycle.

A cargo bicycle having at least a frame, rear wheel, and rear carrier rack, comprising a rear safety cage, pair of footboards and passenger cabin having a canopy and box is provided. The rear safety cage is mounted to the frame. The passenger cabin is mounted to the rear safety cage, rear carrier rack and pair of footboards and forms an interior passenger space for accommodating passengers and protecting passengers from natural or human-made environmental elements. The canopy forms an upper interior space. The box forms a lower interior space and a pair of lower interior side spaces extending outwardly from the lower interior space, straddling the rear wheel. Each of the pair of lower interior side spaces is a self-contained vessel, further protecting lower extremities of passengers from components of the cargo bicycle and debris during operation of the cargo bicycle.
