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.
