A saddle-riding type vehicle includes a driver's seat on which an occupant taking a driving posture sits, a fuel tank disposed in front of the driver's seat and extending in a front-rear direction and a canister formed into a long-length shape that defines a longitudinal direction of the canister, fuel vapors generated in the fuel tank being brought into the canister and adsorbed and held by an adsorbent provided in the canister. The canister is disposed under the fuel tank with the longitudinal direction aligned with the front-rear direction and is entirely covered by the fuel tank in vehicle side view.

A bicycle includes a frame, a suspension assembly and a steering assembly. The frame includes a head tube that rotatably receives a front fork assembly. A steerer tube extends axially away from a fork crown of the front fork assembly. The suspension assembly includes an upper tubular support longitudinally slidable relative to a lower tubular support. The upper and lower supports receive a first positive biasing means and a first negative biasing means. The lower and upper supports are respectively connected to the steerer tube and a stem of the steering assembly such that the upper support slides longitudinally relative to the lower support adjacent the stem and above the fork crown.

An adjustable head angle bicycle assembly includes a steerer tube; a head tube that includes a first annular surface protruding radially inward from an inner wall at the upper end, and a second annular surface protruding radially inward from the inner wall at the lower end; an upper cup that includes a third annular surface engaged with the first annular surface of the head tube; and a lower cup that includes a fourth annular surface engaged with the second annular surface of the head tube.

A straddle-type vehicle including a vehicle body frame to which a steering unit that supports a front wheel in a steerable manner and a stay to which a storage box is configured to be attached are attached. The vehicle body frame is provided with a head tube. The steering unit includes a steering stem rotatably penetrating the head tube, and a pair of left and right front fork tubes coupled to the steering stem and extending toward an axle of the front wheel. The pair of left and right front fork tubes pivotally supports the axle of the front wheel. The stay is located on an outer side of the front fork tubes in the vehicle width direction, and intersects with at least one of the steering stem and the front fork tubes in a side view.

An electric bicycle includes a front wheel, a rear wheel, a driving unit that transmits a driving force to at least one of the front wheel and the rear wheel, a battery housing area that is able to house a battery that supplies power to the driving unit, a head pipe, and a down frame extending from the head pipe in a diagonally downward and rearward direction of a vehicle body. The down frame includes a first extension extending in the diagonally downward and rearward direction of the vehicle body and a second extension extending in the diagonally downward and rearward direction of the vehicle body and provided side by side with the first extension in a width direction of the vehicle body. The battery housing area is located at least partially between the first extension and the second extension.

A vehicle body frame includes a main frame that extends from a head pipe toward the vehicle rear side above an engine and a down-frame that extends downward from one end fixed to the head pipe. The main frame is assembled into a truss shape from a pair of left and right upper frames and a pair of left and right lower frames and reinforcing frames disposed between these upper frames and lower frames. Front end parts of the upper frames are fixed to the upper end side of the head pipe and front end parts of the lower frames are fixed to a part close to the head pipe in the single down-frame.
