A typically one-rider non-powered sports/recreational vehicle has a main body that can be easily converted between a wheeled coaster-wagon configuration and a snow-sled configuration with runners. Typically there are four wheels or four runners: two at front, steerable from a handlebar, and two fixed at rear. For braking in the coaster-wagon configuration, a pair of brake shoe pads, attached to the handlebar, press against the front tires to act as brake shoes when the handlebar is twisted radially via a pair of user handgrips. In the snow-sled configuration, a braking panel, attached centrally on the handlebar, moves downwardly to brake by engaging oncoming snow. In normal use as a coaster or sled, when not braking, this braking panel is nested in an unobtrusive location immediately beneath the front of the main body platform, retained there by spring action that also provides braking hold-off in the coaster-wagon configuration.

What is claimed is: 1. A convertible coaster/sled that can be readily converted between a coaster-wagon configuration with wheels and a snow-sled configuration with runners, comprising: a main body, configured for use as a coaster-wagon and as a snow-sled, provided with a fixed rear axle support assembly including a rear axle, and a steerable front axle support assembly including a front axle and made to be steerable via a single user control element that is also made and arranged to provide braking in at least the coaster-wagon configuration; a first conversion package including four wheels made to be operationally compatible with the rear and front axles so as to constitute the coaster-wagon configuration; and a second conversion package including a pair of front runner units, a pair of rear runner units and spacing means, made and arranged to be assembled to said main body via the axles in place of the four wheels so as to constitute the snow-sled configuration. 2. The convertible coaster/sled as defined in claim 1, further comprising: snow-sled braking means for enabling user braking in the snow-sled configuration. 3. The convertible coaster/sled as defined in claim 2 wherein the single user control element comprises a handlebar assembly affixed to the steerable front axle support assembly. 4. The convertible coaster/sled as defined in claim 3, wherein said snow-sled braking means comprises a panel attached to said handlebar assembly by a user, made and arranged to extend downwardly in response to braking applied by a user to the handlebar assembly, by a user so as to provide braking capability by engaging oncoming snow when said convertible coaster/sled is deployed in the snow-sled configuration. 5. The convertible coaster/sled as defined in claim 3, wherein said coaster-wagon braking means comprises a pair of metal brake pads attached to said handlebar assembly, made and arranged to press against a circumferential portion of the two front wheels in response to braking force applied by a user to the handlebar assembly, by a user so as to provide frictional braking capability when said convertible coaster/sled is deployed in the coaster-wagon configuration. 6. A method of converting a coaster-wagon to a snow-sled, the coaster-wagon having four wheels, two axles each fitted at both axle-ends with wheel-retaining means, and a brake mechanism, including a handlebar to which are attached a pair of brake shoes, made and arranged to apply braking by urging the brake shoes against a pair of the wheels in response to torque applied to the handlebar by a user for braking, comprising the steps of: (a) removing the wheel-retaining means from the axle-ends; (b) removing the wheels from the axles; (c) replacing each removed wheel with a snow-sled runner unit engaging a corresponding axle-end; (d) securing each snow-sled runner unit in place by re-installing the wheel-retaining means at the axle-ends: and (e) attaching to the handlebar a sled brake panel made and arranged to rotate in a downward direction, in response to the torque applied to the handlebar by a user for braking, so as to provide a braking action by engaging oncoming snow during forward motion of the snow-sled. 7. The method of converting a coaster-wagon to a snow-sled as defined in claim 6 comprising, following step (c), the further step of: (c1) installing, on an extending region of each axle-end, a spacer made and arranged to fill a void caused by lesser thickness of the runner units relative to the wheels in mounting regions thereof. 8. A method of converting a coaster-wagon to a snow-sled, the coaster-wagon having a main body fitted with four wheels, two axles each fitted at both ends with wheel-retaining means, and a brake mechanism, including a handlebar to which are attached a pair of brake shoes, made and arranged to apply braking by urging the brake shoes against a pair of the wheels in response to torque applied to the handlebar by a user for braking, comprising the steps of: (a) removing the wheel-retaining means from the axle-ends; (b) removing the wheels from the axles; (c) removing the axles from the main body; (d) replacing each removed wheel with a snow-sled runner unit engaging a corresponding axle-end; and (e) inserting a bolt through a hole provided in each runner unit and through corresponding openings in the main body vacated by the axles; (f) securing each runner unit to the main body by threading and tightening a nut onto each bolt inserted in step (e); and (g) attaching to the handlebar a sled brake panel made and arranged to rotate in a downward direction in response to the torque applied to the handlebar by a user for braking, so as to provide a braking action by engaging oncoming snow during forward motion of the snow-sled.
