Two toys share one battery here: run the 6V ATV quad on its own, or clip the trailer on in three steps and let a 3 year old haul stuffed animals across a patio. A power button wakes it and a three-position switch sets forward, stop, or reverse, so nothing needs interpreting. Speed tops out between 1.3 and 1.9 mph, and multi-terrain wheels track across asphalt, wood flooring, cement, and brick. A seat lock keeps the saddle from shifting under a rider mid-turn.
