The bike (10) comprises a frame provided with a front wheel (12) oriented by a handlebar, a saddle (39) and a crankset. The bike (10) further comprises two pivoting rear uprights (18, 19) each carrying a rear wheel (22, 23), the pivoting rear uprights being mounted by independent pivot links on the frame.

The crankset actuates two drive means (26, 27, 59, 60) independent of the rear wheels. The drive means of each rear wheel comprises a free wheel (59, 60). The drive means are configured such that, in a bend, only the rear wheel located on the inside of the bend is driven by the crankset, the rear wheel located on the outside of the bend freewheeling and not being driven by the crankset.

A front two-wheel leaning vehicle, including a handle, a steering shaft, a linkage mechanism and a load transfer mechanism. The load transfer mechanism includes a left-foot-placing part and a right-foot-placing part located between the left front wheel and the rear wheel, for left and right feet of the driver to be respectively placed thereon. The load transfer mechanism transfers a load to the left and right portions of the linkage mechanism through the left-foot-placing part and the right-foot-placing part, or through the right-foot-placing part and the left-foot-placing part, respectively. The steering shaft includes a handle adjusting mechanism configured to adjust, with respect to the left-foot-placing part and the right-foot-placing part, at least one of a handle height, which is a distance from a midpoint between the left and right front wheels to the grip, or an offset amount of the handle with respect to a rotation axis of the steering shaft.

A vehicle includes a control switch that is configured to generate an operation signal, and a controller that is electrically connected to the control switch to receive the operation signal therefrom, and that is configured to, in response to receipt of the operation signal, transmit a control signal to a tilting mechanism for making the tilting mechanism operate in one of a locked state and an unlocked state. After the vehicle is powered on, the controller is further configured to, when the controller has continuously received the operation signal for a predetermined reception time, determine that the control switch is abnormal, stop transmitting the control signal and control a warning unit to output a warning signal.

A rotation locking device includes a locking module and at least one engaging member. The at least one engaging member is rotatably coupled to the locking module. The locking module is configured to engaging and disengage the at least one engaging member, thereby refraining the at least one engaging member from rotating relative to the locking module.

There is described a three-wheeled vehicle (1) with two front steered wheels and two footboards (41.1, 41.2) on which the driver stands to drive the vehicle. The footboards are supported on a tilting four-bar linkage, having a front crosspiece 27 and a rear crosspiece 33, between which two rocker arms 31.1 and 31.2 extend. The front steered wheels are supported by the rocker arms and rotate around steering axes (S.1, S.2).

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 Roberts four-bar linkage.

A vehicle is provided with a vehicle body, N (N is an integer equal to or larger than 2) wheels including one or more front wheels and one or more rear wheels, a force generator, and a force controller. The N wheels include one or more turn wheels turnable in the width direction of the vehicle. The force generator is configured to generate a force which changes a yaw angular acceleration. The force controller is configured to control the force generator. A gravity center of the vehicle body is located away from a rotation center of the vehicle toward front side or rear side when the vehicle turns. The force controller controls the force generator to control a roll torque in the width direction acting on the vehicle body.

A leaning vehicle includes a base member, an upper arm, a lower arm, a first support member, a second support member, a first wheel, a second wheel, and a steering operation member. The upper arm, the lower arm, the first support member, the second support member constitute a parallel link mechanism. The first wheel is movable integrally with the first support member in a turning direction of the base member. The second wheel is movable integrally with the second support member in the turning direction of the base member. According to turning of the base member by operating the steering operation member, all of the upper arm, the lower arm, the first support member, the second support member, the first wheel, and the second wheel turn around a turning center of the base member.
