What age is the Costway Girls Bike 12" for?

It is aimed at young beginners, roughly ages 2 to 4. Check the child's inseam against the seat height before buying, since 12-inch bikes are outgrown fast.

Does it come with training wheels?

Yes. The listing includes training wheels and a front basket along with the bike.

What kind of brakes does it have?

It uses rim brakes, which are simple and light but need a child's hand strength. Check that a small rider can squeeze the lever.

Is it ready to ride out of the box?

Expect some assembly: handlebars, pedals, training wheels and basket usually need fitting. Check bolt tightness and brake adjustment before the first ride.

How does it compare with other 12-inch kids' bikes?

It matches the usual 12-inch formula of steel frame, rim brakes and training wheels, and adds a front basket. Bikes without a basket or training wheels are lighter, but you fit those parts yourself.
