A rear wheel suspension adjusting arrangement for use in a vehicle includes a configuration adjusting arrangement and an activating arrangement. The vehicle includes a frame having a front and a back, a suspended rear drive wheel that supports the frame, and a suspension system for connecting the rear drive wheel to the frame. The configuration adjusting arrangement is capable of changing the positioning of the suspension system relative to the frame such that the suspension system may be moved into an uphill configuration when the vehicle is traveling uphill and such that the suspension system may be moved into a downhill configuration when the vehicle is traveling downhill. The activating arrangement activates the changing of the configuration adjusting arrangement to cause the configuration adjusting arrangement to change the positioning of the suspension system relative to the frame while the vehicle is being used.

A bicycle folding mechanism includes a frame, a stem, and a front fork. The frame includes a front tube at an end thereof. The stem is inserted into the front tube. The stem is connected and pivotal relative to the frame. The stem has an end, which is adjacent to the frame, connected with a connecting seat. The front fork includes at least one connecting end and at least one front end on opposite ends. The at least one connecting end is connected and pivotal relative to the connecting seat such that the front fork is pivotal relative to the connecting seat. The front fork is pivotal between a deployed position in which the at least one front end is positioned away from the frame and a folded position in which the at least one front end is positioned adjacent to the frame.

A vehicle includes a front differential, a pair of constant-velocity joints, and a steering mechanism. The steering mechanism includes a pitman arm, a pair of tie rods, a pair of first link arms each connecting the pitman arm with a corresponding one of the pair of tie rods, and a pair of second link arms each connecting a corresponding one of the pair of first link arms with a body frame. In a plan view, at least a portion of each constant-velocity joint is located between first and second straight lines extending in a fore-aft direction and through first and second connectors extending between the tie rods and the first link arms. The first connector, the second connector, and at least a portion of each constant-velocity joint are located between third and fourth straight lines extending between the first and second link arms.

The saddle-riding motor vehicle (1; 107; 207) comprises a rear driving wheel (5; 105; 205) and a front steered wheel (7; 107; 207). The front steered wheel (7; 107; 207X, 207Y) is connected to a rotatable arm (9; 109; 209X, 209Y) provided with a rotary motion about a steering axis (A-A). A wheel support (37; 137) is connected to the rotatable arm (9; 109; 209) with the interposition of a suspension (17; 117; 217X, 217Y) comprising a shock absorber (22; 122). The suspension (17; 117) comprises a Watt four-bar linkage.

A foldable electric scooter and a manufacture method of the same. The foldable electric scooter includes a main body assembly, a front fork assembly located at the front end of the main body assembly, a rear fork assembly located at the rear end of the main body assembly, a telescoping plate assembly located on top of the front fork assembly and a handlebar assembly located on top of the telescoping plate assembly. The foldable electric scooter has a double headset design that increases a rake angle for more steering stability while still keeping the steering upright for an upright holding of the handlebars. The foldable electric scooter is manufactured by stamping of flat plate material.
