Balance and steering systems and methods. In one aspect, a balance practice device with an inverted pendulum balanced with a steering arrangement. In another aspect, first and second two-wheeled vehicles coupled in parallel for simultaneous banking by a motorized banking arrangement, a laterally moveable weight, or a mechanism for steering the steering arrangements of the first and second two-wheeled vehicles. Still other aspects of the invention have a laterally moveable two-wheeled vehicle and a tiltable display scene for simulating vehicular motion. Alternatively, a two-wheeled vehicle can be retained relative to a pivotally supported arm. Still further, a vehicle can have front and rear wheeled trucks each with a cambered caster wheel for inducing a difference between the angle of attack of the trucks and a longitudinal orientation of the vehicle.
