The Tesla Model S has gotten a kid-friendly makeover.

Radio Flyer, which makes the famous little red wagons and tricycles, announced on its website that it will soon begin shipping mini Tesla Model S cars for kids for $499 each.

Pre-orders are now open and the cars will ship in May.

The one-seater cars were created in collaboration with Tesla (TSLA) and are for kids between the ages of three to eight. The cars come in three colors: red, blue and "midnight silver metallic." They boast special lithium ion batteries that are supposed to charge faster and last longer than any other battery-powered kiddy car.

"This baby Model S really is quite fun," tweeted Tesla's CEO Elon Musk.

The cars include working headlights, a "spacious interior" and a trunk in the front of the car. It can reach a top speed of six miles per hour.

Buyers also have the option to purchase premium batteries, special license plates and mini indoor car covers.

For adults, Tesla currently sells just two models: The Model S and the new Model X.

The Tesla Model S starts around $75,000, though a federal tax credit brings the price down by about 10%.

The company will also begin taking reservations and deposits for the Model 3 on March 31. This is Tesla's "cheaper" electric car that is expected to cost in the neighborhood of $35,000. Federal and state tax credits may knock $7,500 to $10,000 off the purchase price in the U.S.
