A vehicle (1) comprises a frame (17); a front ground engaging sphere (2) which is rotatable about a first axis which is transverse and fixed relative to the frame (17); a rear ground engaging sphere (3) which is rotatable about a plurality of axes, and gripping portions (11) which are provided towards the front of the vehicle (1), for a rider to hold. A support member (25) is connected pivotally to a rear portion of the frame (17) and projects longitudinally of the vehicle (1) and downwardly from the point of connection to the frame (17) to a remote part of the support member (25). The rear sphere (3) is connected to the remote part of the support member (25) for rotation about a second axis which is transverse and fixed relative to the support member (25). The support member (25) is pivotal with respect to the frame (17) about a third axis which extends downwardly and longitudinally of the vehicle (1).

A control device 20 of a rideable mobile body 1 determines a target speed of the rideable mobile body 1 according to at least the steering operation by a rider, and controls the travel of the rideable mobile body 1 according to the target speed. In the processing for determining a target speed, the target speed is restricted according to the positional relationship between a virtual wall set in a travel environment of the rideable mobile body 1 and the rideable mobile body 1. Thus, the comfort of the rider is secured while the travel of the rideable mobile body is restricted by the virtual wall.

An approach is provided for a foldable bike which comprises a front fork, a top tube, a down tube, a pivot hinge and the pair of auxiliary wheels. The pivot hinge is connected to the first end of the front fork, a second end of the top tube and the first end of the down tube. The first end of the top tube is pivotally connected to the pivot hinge. The first end of the top tube is pivotally connected to the pivot hinge. The auxiliary wheels mounted on the two respect sides of the rear wheel that are extended backwardly from the center of the rear wheel. The pivot hinge allows the front fork and the top tube to be folded toward the down tube. The auxiliary wheels against the ground when the the bike is folded, which is capable of standing and being pulled by a person.

A device for exerting torque on an object includes: at least one rotating mass rotatably supported about an axis of rotation; a drive for driving the rotating mass; a bearing which enables a change in the alignment of the axis of rotation relative to the object; and a coupling unit which engages on the bearing and couples the rotating mass to the object.
