Steerable wheel assembly with damping and centering force mechanism for an in-line skate or roller ski

A recreational wheel device having a chassis for supporting a user and having a front wheel assembly and a back wheel assembly mounted to the chassis, wherein at least one of said front and said back wheel assemblies is a steerable wheel assembly that includes only a single wheel,

• said single wheel being a steerable wheel that steers about a steering axis and has a rotation axis said single wheel having an outer radius
• a wheel bearing having a bearing outer radius and mounting said steerable wheel to rotate about said rotation axis
• a steering pivot assembly substantially disposed within the outer radius of said steerable wheel and extending radially beyond said bearing outer radius of the wheel bearing and
• a wheel support assembly structurally carrying the wheel bearing, said wheel support assembly being mounted to pivot on the steering pivot assembly about the steering axis such that the steerable wheel responds to weight distribution of a rider supported on the chassis to actively steer the device.
