An auxiliary wheel mechanism 151 of a two-wheeled vehicle disclosed herein includes an auxiliary wheel 1, a saddle support member 7, a transmission member 9, and an auxiliary wheel urging member 23. The auxiliary wheel 1 is supported by a vehicle body 11 to be located on a side of a rear wheel 13 and to be movable between a retracted position retracted from a road surface 17 and an operative position where the vehicle body 11 is supported against the road surface 17 so as not to tilt. The saddle support member 7 is provided on the vehicle body 11 and supports a saddle 27 such that the saddle 27 is movable backward and forward. The transmission member 9 transmits a backward and forward movement of the saddle 27 to the auxiliary wheel 1 such that the auxiliary wheel 1 is located at the retracted position when the saddle 27 is located at a front position, and the auxiliary wheel 1 is located at the operative position when the saddle 27 is located at a rear position. The auxiliary wheel urging member 23 urges the auxiliary wheel 1 toward the retracted position. Accordingly, it is possible to achieve the auxiliary wheel mechanism that is for the two-wheeled vehicle and enables a rider to move an auxiliary wheel between a retracted position and an operative position without a manual operation of the rider.

A modular cargo system for an off-road vehicle includes a triangular center case between a right side case and a left side case, each having a base attached downwardly to a platform on the vehicle while also defining a floor plane for resting on a flat floor surface. The side cases include non-parallel side walls, each defining an interior space large enough to hold a rider's helmet. Each case includes a handle on a hinged lid, enabling the side case to be carried with a single hand while the lid is closed. The hinge is on a leading side wall of the cases, latched on a trailing side wall of the cases, and clips to hold the side cases downward to the platform are on the trailing side walls.

An auxiliary fixing device for a bicycle includes a body and a limiting rod unit. The limiting rod unit includes first and second limiting rods coupled to the body. Each of the first and second limiting rods includes a connecting portion, a limiting portion, and an extension portion between the connecting portion and the limiting portion. The extension portion of the first limiting rod has an end adjacent to the connecting portion of the first limiting rod and another end extending away from the second limiting rod. The extension portion of the second limiting rod has an end adjacent to the connecting portion of the second limiting rod and another end extending away from the first limiting rod.

A transformable bicycle or tricycle is presently provided. The transformable bicycle has a first seat and a second seat disposed rearward or forward of the first seat. At least one of the first seat and the second seat is transformable and has a planar seat and a planar back. The transformable seat is configured and disposed to transform into an enclosure or into a flat planar bench having the planar seat and the planar back substantially in the same plane.

According to one or more aspects of the present disclosure, a removable seat assembly is provided comprising a first mounting feature engageable with the tunnel of a snow vehicle, and optionally a second mounting feature engageable with the tunnel of the snow vehicle. The first mounting feature may automatically engage the tunnel upon engagement of the second mounting feature with the tunnel. The seat assembly may comprise a frame base, a riser defining a chamber therein positioned on the frame base, a seat back frame, and an arm rest secured to the frame base and the seat back frame.

A motorised mobility device including: a wheeled base; a saddle seat; and an adjustable support extending between the wheeled base and the saddle seat. The adjustable support is adjustable to raise the saddle seat from a sitting position to a standing position

Disclosed are a personal mobility and a control method thereof. The personal mobility includes a front body on which a front wheel is installed, and a rear body slidably coupled to the front body in a front-rear direction to enable wheelbase adjustment and on which a rear wheel is installed.

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.

A sensing-enabled automatically foldable scooter frame includes a support frame, a seat, an electric pushrod, a sensor, a controller, and an operating member. The electric pushrod is provided at the support frame to drive folding and unfolding of the support frame. The sensor is provided at a surface of the seat. The controller receives a signal from the sensor to control extension or retraction of the electric pushrod. The operating member is electrically connected to the controller. The operating member is disabled when the sensor detects existence of pressure, and the controller controls the electric pushrod in a retracted state, thereby ensuring the support frame in an unfolded state. The operating member is enabled when no pressure is detected, and the controller drives folding or unfolding of the support frame. The present invention can prevent a scooter frame from being folded accidentally, thereby protecting a user from being hurt.
