Abstract: 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.
