A side-stand for a motorcycle enables both improvement in appearance and weight reduction by using a tapered pipe member. A side-stand for a motorcycle includes an elongate portion having a hollow structure, and a grounding portion. An outer shape of the elongate portion is tapered in appearance toward the grounding portion and, in a state in which the side-stand is unfolded, the elongate portion looks thinner as a whole in a side view than in a front view of a vehicle body. The elongate portion has a wall thickness on the distal end side equivalent to or smaller than a wall thickness on a proximal end side. The elongate portion is formed by increasing a diameter of a distal end side inner peripheral portion of a round pipe member by cutting, and then swaging an outer peripheral portion to reduce the diameter and obtain a tapered shape.

A non-backdrivable passive balancing system for a single-axle dynamically balanced robotic device includes a body that includes a distal end and a proximal end, a controller module, and an actuator communicatively coupled to the controller module of the single-axle dynamically balanced robotic device. The actuator receives an engagement signal from the controller module, the engagement signal corresponding to an indication that the dynamically balanced robotic device is stationary, and the actuator causes the linkage to move the body from a disengaged position to an engaged position such that the distal end of the body contacts a ground surface and supports the dynamically balanced robotic device in a substantially upright position.

A bike having an energy recovery device includes a driving wheel that is coupled to a rear wheel driving shaft pulley of the bike and rotates with the rear wheel of the bike. When a wire is pulled by the bike rider, an outer peripheral surface of a rotating wheel contacts an outer peripheral surface of the driving wheel and rotates together by means of friction with the driving wheel. When the wire pulling force is released, contact with the driving wheel is released. A piston moves in the forward/backward direction inside a cylinder of a compressor. During operation, air is compressed by the movement of the piston, exits through an exhaust opening formed on the rear portion of the cylinder, and is stored in an air tank through an air hose.

A solar-powered vehicle that includes a body having a front end, rear end, top and opposing sides; two or more wheels; and a first and second solar panel assembly respectively disposed on the opposing sides of the body.

An electric vehicle includes a frame unit and a vehicle body cover unit. The frame unit includes tread tubes extending toward a rear side and arranged pairwise as a left tread tube and a right tread tube. The vehicle body cover unit includes a tread board that shields the left tread tube and the right tread tube. The frame unit is provided with a battery box that receives and holds therein a battery and the frame unit is provided thereon with a side stand. The electric vehicle is provided with an electric connection mechanism on the vehicle body at one side thereof opposite to the side stand for replenishing the battery with external electric power so that a drawback that the electric vehicle tips over when replenishment of electric power is being made to the battery is prevented to thereby improve utilization of the electric vehicle.

A stand support structure of a saddle riding vehicle has a main frame, a pivot block configured to swingably support a rear wheel-supporting swing arm, and a stand-supporting bracket. The pivot block has a first plate and a second plate attached to the main frame. The first plate and the second plate are coupled to each other. The first plate has a protrusion protruding outward farther than an extension end of the second plate. The stand-supporting bracket is coupled to a surface of the protrusion facing in a vehicle width direction.
