Abstract
A children's ride-on vehicle with a reduced scale chassis having a seat configured to accommodate at least one child. The vehicle further includes a drive assembly, which includes one or more drive wheels and a battery powered motor assembly. The battery powered motor assembly includes a motor output and a torque attenuation system, which is configured to regulate the transmission of torque from the motor assembly to the one or more drive wheels. The torque attenuation system incorporates a force reducing mechanism adapted to receive a rotational input from the motor output and regulate the transmission of that rotational input to the one or more drive wheels. In some embodiments of the invention, the torque attenuation system is a self-contained system, and in some embodiments of the invention, the torque attenuation system is adapted to be retrofit on existing children's ride-on vehicles.
