A vehicle includes a frame including a lower frame portion made from a first material and an upper frame portion made from a second material different from the first material, a center of gravity of the upper frame portion being above a center of gravity of the lower frame portion, at least one front suspension system connected to the lower frame portion, at least one front ground engaging member connected to the front suspension systems, at least one rear suspension system connected to the lower frame portion, at least one rear ground engaging member operatively connected to the rear suspension system, a power pack connected to and supported by the lower frame portion, a seat connected to and supported by at least one of the upper frame portion and the lower frame portion, and at least one body panel connected to and supported by the upper frame portion.

A folding scooter frame (100) includes a front vehicle frame (110), a rear vehicle frame (120) and a folding seat support frame (8). The front vehicle frame (110) and the rear vehicle frame (120) are pivotally connected. The folding seat support frame (8) includes a linkage rod (81) and a frame body, wherein a front end of the linkage rod (81) is connected with the front vehicle frame (110), a rear end of the linkage rod (81) is pivotally connected with the frame body, and the linkage rod (81) is able to swing as the front vehicle frame (110) is folded and thus drives the frame body to fold. The folding scooter frame (100) has the advantages of quick and convenient folding operations.

A cushioning body for a leg rest of a rollator walking aid is in the form of an elastic molded body and has an upper side, which, when the elastic molded body is attached to a support member of the leg rest of the walking aid and the walking aid is used by a person, faces a bent leg of the person, a lower side, and a depression disposed on the upper and/or lower side. The depression is configured as a recess or as an area in which the material of the molded body has a reduced density. In the depression, a protuberant part of the anterior surface of the knee and of the neighboring portion of the lower leg is received when a leg of a person is resting on the cushioning body, in particular when the bent leg is in contact with the upper side of the cushioning body.

A system for controlling tilting of two wheels of a vehicle, mechanically anchored to the chassis by a first and a second oscillating anchor arm is provided. The system has a first cylinder and a second cylinder suitable for being interposed between the chassis and the first and second oscillating anchor arms respectively. The first and second cylinders have respectively a first chamber and a second chamber with variable volume and containing a working fluid. Transfer of working fluid from the first to the second chamber results in an increase in the volume of the second chamber. Transfer of working fluid from the second to the first chamber results in an increase in the volume of the first chamber. A pipe connects the first and second chambers so that working fluid is alternately transferable from the first to the second chamber and from the second to the first chamber.

A railway vehicle includes two axles with wheels at ends thereof, and a frame rotatably supporting the axles. A seat is carried on the frame adjacent to pedals which are coupled to at least one of the wheels, typically through one of the axles. A battery and electric motor are configured to also supply power. The electric motor is adjustable to deliver controllable amounts of electric power to drive the wheels, separate from or in addition to pedal power delivered to the wheels. A trailer accessory can be towed on the rails by the vehicle. A turntable is provided with rail segments thereon, rotatable relative to a base, and with ramps on at least one end of each rail segment alignable with left and right rails of the railway. Vehicles can roll up the ramps onto the rail segments and then pivot 180° for operation in a reverse direction.

A leaning vehicle includes an actuator, a left steerable front wheel, a right steerable front wheel, a steering mechanism and a leaning mechanism. The steering mechanism includes a first center steering shaft, a second center steering shaft disposed at the front side of the first center steering shaft, and a center steering shaft rotation interlocking mechanism that interlocks rotation of the first center steering shaft with rotation of the second center steering shaft. The actuator is provided between a left end and a right end of a link member of the leaning mechanism in the left-right direction. At least one part of the actuator is provided at a position that overlaps with a movable range of the center steering shaft rotation interlocking mechanism as viewed from the up direction or the down direction.
