A steerable wheel assembly for an in-line skate or roller ski comprises a hollow or dish-shaped wheel (11), a wheel bearing (13), and a wheel support (14) connecting the wheel (11) to a steering pivot (16) which is substantially disposed at a distance measured radially from the rotational axis of the wheel (11) where that distance is greater than the outer radius of the wheel bearing (13) and less than the outer radius of the wheel (11). Steering of the wheel occurs as the user's weight is displaced or the chassis of the device is inclined with respect to the ground toward the desired turning direction. A chassis for an in-line skate or roller ski containing a damping and centering force mechanism which may be used to moderate the behavior of a steering mechanism or suspension mechanism comprises a structural member (21), a damper housing (17), a damper piston (19), a fluid chamber (24), and a centering force mechanism (18).

[ What is claimed is:] [1.]1. 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 radiusa wheel bearing having a bearing outer radius and mounting said steerable wheel to rotate about said rotation axisa 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 anda 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.
