A personal transport vehicle is provided, which includes a front wheel assembly having a front rim and a front tire seated on the front rim, and a rear wheel assembly having a rear rim and a rear tire seated on the rear rim. The vehicle also includes a motor disposed within the rear rim of the rear wheel assembly and coupled to a mount of the rear rim, where the motor is configured to rotate the rear tire to cause movement of the personal transport vehicle. The vehicle further includes a frame coupled to the front wheel assembly and to the motor disposed within the rear wheel assembly, and a steering arm coupled to the front wheel assembly within the front rim for controlling movement of the front tire for steering the personal transport vehicle.

A personal transport vehicle is provided capable of staying upright without the need for a stand by incorporating tires having an advantageous design combined with an overall lowered center of gravity. The personal transport vehicle further incorporates a hub and steering assembly configured within the front wheel of the vehicle, as well as a bake and propulsion means configured within the rear wheel of the vehicle. Finally, the personal transport vehicle is capable of being folded into a compact configuration, lending itself to ease of shipment, storage and transport.

A method and system for assembling a vehicle of a family of vehicles includes providing a group of engines. A first engine including a first number of cylinders corresponds to a first vehicle. A second engine including a second number of cylinders corresponds to a second vehicle. The second number is greater than the first number which is at least one. A cylinder plane extends vertically and longitudinally. At least one cylinder is disposed at least partly forward of a front wheel plane. The transmission assembly is rearward of the selected engine and one of the transmission assembly and the selected engine is in a same location whether the selected engine is the first or the second. The seat is at least in part longitudinally rearward of the transmission assembly. The selected engine is laterally disposed between the centers of the footrests.

A leaning vehicle includes a vehicle body, a left wheel, a right wheel, left and right bearings, left and right axle, left arm, right arm, and lean mechanism. The left arm supports the left wheel from inside in a vehicle width direction. The right arm supports the right wheel from inside in the vehicle width direction. The lean mechanism causes the left wheel and the right wheel to lean about a front-rear direction as a rotation center when the vehicle body leans about the front-rear direction as a rotation center. The single bearing is inserted into a hub hole of the left wheel. The single bearing is inserted into a hub hole of the right wheel.

In an embodiment, there is provided a motorcycle comprising at least one front wheel, at least one rear wheel and a vehicle body, the vehicle body comprising a substantially open elongate duct extending longitudinally through a central portion of the vehicle body between an open inlet aperture arranged at a front portion of the vehicle body and an open outlet aperture arranged at a rear portion of the vehicle body.
