A ride-on toy car for kids.

Wheels/tires#

The minimal upgrade is to replace the plastic wheels with rubber ones. What’s needed: measure the wheel and axle diameters, purchase wheels, and attach the motor drive to the new wheels.

Power 12V#

Instead of the built-in battery, you can connect a 12 or 20-volt battery from power tools. Reports say the motors work fine, but to avoid burning out the electronics (radio/Bluetooth and lights) a step-down converter is required.
