Parental remote control mode lets adults steer and choose from three speeds, while battery-operated mode gives kids direct control with high and low speed options to match their skill. The 12V 4.5AH battery moves the 45 x 27 x 22.5 in car at 1.2-2.8 mph so young drivers travel at a manageable pace, and soft start and stop help limit sudden jolts. Spring suspension on each wheel works with the wide seat and safety belt to support riders up to 66 lbs. Opening doors with safety locks, bright LED lights, built-in music and story functions, USB and TF interfaces, a rear storage box, and a pull handle add realistic and convenient features for rides on wood, asphalt, or brick surfaces.
