The invention relates to a bicycle (100) having a frame structure (200) that comprises a swingarm structure (225) including a first substantially U-shaped sheet metal part for holding a wheel (103), the frame structure further comprising a frame bridge (219) consisting of a second substantially U-shaped sheet metal part. The first U-shaped sheet metal part is bent substantially in a first bending plane (P) to form a first U-shape, and the second U-shaped sheet metal part is bent in a second bending plane (Q) to form substantially a second U-shape. The first bending plane extends substantially perpendicular to the second bending plane.

Handlebars having a master tube, two handgrips at opposite ends of the master tube, a stem for attaching to a fork, and at least one portion with doubled section, the cross section of which comprises an upper outer wall, a lower outer wall, an upper inner wall and a lower inner wall. The upper outer wall is distanced from and joined to the upper inner wall, the lower outer wall is distanced from and joined to the lower inner wall, and the upper inner wall is distanced from the lower inner wall.

Handlebars having a master tube, two handgrips at opposite ends of the master tube, a stem for attaching to a fork, and at least one portion with doubled section, the cross section of which comprises an upper outer wall, a lower outer wall, an upper inner wall and a lower inner wall. The upper outer wall is distanced from and joined to the upper inner wall, the lower outer wall is distanced from and joined to the lower inner wall, and the upper inner wall is distanced from the lower inner wall.

A two-wheeled vehicle includes a frame assembly, a plurality of ground-engaging members for supporting the frame assembly, and a cooling assembly positioned below a head portion of the frame assembly and intermediate vertically-extending frame tubes of the frame assembly. A lower end of the cooling assembly is coupled to a lower end of the vertically-extending frame tubes, and an upper end of the cooling assembly is frictionally retained at an upper end of each of the vertically-extending frame tubes.

There are provided a vehicle and a cooling structure for an electrical component including: a cover including a cover inlet that introduces air into an accommodation space for the electrical component, and a cover outlet that discharges air from the accommodation space; and a duct including a duct inlet facing forward in a traveling direction, a duct outlet communicating with the cover inlet, a duct flow path that guides air flowing from the duct inlet to the duct outlet, and a deflection wall that deflects a flow of air inside the duct flow path. The duct flow path includes an outlet flow path positioned on a downstream side of the deflection wall in a flow direction of air and extending toward the duct outlet, and the electrical component is disposed to face the cover inlet in an extending direction of the outlet flow path.
