Most models offer both child-operated controls (foot pedal or manual driving) and parental control via a remote (commonly 2.4G) or parental override. Product listings usually indicate whether a model supports child-only operation, remote-only control, or dual/manual-and-parental-control modes.
Top speeds vary by model. Documented values in listings range roughly from 1.9 to 5 MPH. Many models offer adjustable speed settings or come in single-speed options such as about 2–3 MPH, 3–5 MPH, with some higher-performance listings up to roughly 4.5–5 MPH.
Common onboard entertainment and convenience features include built-in MP3 players, USB ports, FM radio, Bluetooth/wireless connections, LED headlights and tail lights, horns and built-in music, plus practical additions like storage compartments and bottle holders.
Stated maximum loads vary widely by model, from roughly 42 pounds up to about 132 pounds. Other common figures include 44 lb, 66 lb, 100 lb, and one spec lists 48 kg (about 106 lb).
