  1. phong

    Super nice dirt bikes for kids! If you are having second thoughts, don’t hesitate to buy. These bikes are really nice and take minutes to assemble just a few parts. Buy a helmet, gloves and knee and arm pads because these bikes are fast! They are excellent to learn how to ride and very easy maintenance. Awesome bikes!
