A vehicle with a power unit includes: a body frame with said power unit mounted to said body frame; at least one front wheel supported by the body frame in a front portion, and at least one rear wheel supported by the body frame in a rear portion; an electric machine capable of assisting said power unit; and an auxiliary power source electrically connected to said electric machine. The vehicle further includes a first set of foot pegs for a rider and a second set of foot pegs for a pillion. A quadrilateral region is defined between said first set of foot pegs and said second set of foot pegs, and said electric machine and said auxiliary power source are disposed substantially within said quadrilateral region when viewed from vehicle top.

A bicycle saddle can be customized to a rider's body to achieve desired support and comfort. The support shell is configured to support a rider's body and can be heated by an external heater and/or at least one internal thermal element operable to heat the bicycle saddle such that the saddle is molded to the rider.

A bicycle saddle includes: a base structure having a top portion; and a cushion coupled to the top portion of the base structure, the cushion including a first lateral side and a second lateral side separated by a longitudinal plane, wherein each of the first lateral side and the second lateral side includes: a first region having a first stiffness; a second region having a second stiffness that is less than the first stiffness; and a third region having a third stiffness that is less than the second stiffness, wherein a perimeter of the second region is at least 75% enclosed within the first region, and wherein a perimeter of the third region is at least 75% enclosed within the second region.

A bicycle seat cover for a bicycle seat with a rigid substrate and a cushion thereon, includes a stretchable polymeric layer forming a top surface, a seat horn cover, a seat conforming sidewall, and a partial seal bottom surface covering and integral honeycomb cells extending from an underside of the top surface, each cell closed at its top by the top surface and open at its bottom.

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 bicycle saddle can be customized to a rider's body to achieve desired support and comfort. The support shell is configured to support a rider's body and can be heated by an external heater and/or at least one internal thermal element operable to heat the bicycle saddle such that the saddle is molded to the rider. A molding indicator in thermal contact with the saddle measures a molding factor, such as temperature or deflection, and visually indicates the measured molding factor for molding the bicycle saddle.

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.
