Children's ride-on vehicles with reconfigured, or flexed panel, bodies. The bodies include at least one reconfigured, or flexed, body panel that is retained in a biased, or flexed, configuration and/or against its internal bias to move from the flexed configuration. In some embodiments, the body has an exterior shape that is determined at least in part by the at least one flexed body panel. In some embodiments, the at least one body panel is integrally formed with other portions of the ride-on's body, and in some embodiments, a portion of the body panel remains in an unflexed configuration when another portion of the body panel is retained in the flexed configuration. In some embodiments, the vehicles include at least one retainer that engages a flexed panel and retains the panel in a defined position relative to another portion of the ride-on's body.
