The HB-EATV 800 features a crucial safety key switch, usually located under the frame or near the footrests. This allowed parents to lock the quad into three distinct speed tiers: ~5 mph (8 km/h) – Perfect for beginners. Medium: ~10 mph (16 km/h) – For intermediate riders. High: ~15+ mph (24+ km/h) – For experienced riders only. Shifting Gears
Turn the handlebars fully to ensure smooth steering alignment.
Verify that the parental speed key is turned entirely into one of the designated speed slots and is not stuck between settings.
