A two-wheeled mobility system having a frame with a first and second end and a deck extending therebetween. A handle portion is pivotably coupled with the first end of the frame. A wheel is coupled with the handle portion such that relative movement of the handle correspondingly pivots the first wheel. A second wheel is coupled with the second end of the frame and is rotationally movable relative to the frame. A bracket assembly is attachable to the frame and includes a first bracket for mounting to the frame at about the second end of the frame. A stand is connected to the first bracket and extends radially outward from the first bracket at an angle of from about 20 degrees to about 35 degrees. The stand may be used as a kickstand to support the two wheeled mobility system from falling on the ground when leaned over.

A vehicle including a first frame extending in a front-rear direction from a front wheel to a rear wheel, a second frame, a steering part supported by the second frame, a support portion movably supporting the steering part about a pivot axis so that the steering part is positioned above the front wheel when the vehicle is in a traveling posture and is positioned above the rear wheel when the vehicle is in a folded posture, and a movement restriction portion provided near the rear wheel so as to restrict a movement of the steering part toward the rear wheel when the posture of the vehicle changes from the traveling posture to the folded posture.

A straddle vehicle comprises a shift drum formed with an engaged part; a transmission case formed with an insertion hole, a gear position sensor including an engagement part engageable with the engaged part; and a seal ring fitted to the outer peripheral surface of the gear position sensor, and the insertion hole includes a first inner peripheral surface with which the seal ring is in tight contact in a state in which the engagement part is engaged with the engaged part, and a second inner peripheral surface located closer to an entrance of the insertion hole than the first inner peripheral surface and having a diameter larger than a diameter of the first inner peripheral surface, and in a state in which the seal ring has reached an entrance of the first inner peripheral surface, at least a portion of the engagement part is fitted to the engaged part.

A kickstand assembly includes a post and a seat. A bicycle includes a frame and the kickstand assembly coupled to the frame. The post is disposed along a longitudinal axis and includes a first distal end and a second distal end. The seat is disposed at the first distal end of the post. The seat is movable between a use position and a non-use position. The kickstand assembly includes a kickstand disposed at the second distal end of the post, and extends outwardly away from the post transverse to the longitudinal axis. The kickstand is movable between a use position and a non-use position. The seat and the kickstand are fixed relative to each other at the respective first and second distal ends of the post such that movement of the seat to the non-use position directly causes movement of the kickstand to the use position.

A bicycle stabilizer device includes a first post attached to a handlebar stem of a bicycle and a second post attached to upper frame portion of the bicycle; and a stabilizer bar configured to be reversibly connected between the first and second posts. Stabilizing a bicycle includes providing a stabilizer bar comprising a front portion end and a rear portion, attaching the second end to an upper portion of a bicycle frame. A post is disposed along a handlebar stem of the bicycle. The first end of the bar is reversibly connected to the post, the reversibly connecting stabilizing a front wheel of the bicycle to remain in a forward position.

A motor dolly comprises a first board member, a first supporting frame, a second supporting frame, a first connecting rod, a second connecting rod, a second plate and a third supporting frame. Each above-mentioned member is formed by stamping a plates into a U-shaped frame to provide better strength.

A device for supporting a wheelchair includes a frame and a support system. The first end of the frame is attached to an axle of the wheelchair. The second end of the frame is attached to a wheel for allowing translation of the device over a surface. The support system is coupled to the frame and may be positioned to catch a back of the wheelchair upon reclining of the wheelchair during a wheelie. The position of the support system with respect to the frame is adjustable in order to catch the wheelchair at varying angles of reclining. As the user of a wheelchair develops skill in performing a wheelie, the position of the support system may be moved further away from the wheelchair.
