Over the weekend, my husband and his brother bought the mini motorized bikes. We will not let our daughters ride on them alone(6 and 8yrs old). They can ride with their dad and that is it. Well his brother let his girls who are 7 and 9 ride alone with out a helmet. The 7 yr old was going way to fast and crashed. She looks horrible, and has a large bruise on her face at her jaw line. her teeth went threw her tongue and her bottom lip. She put band aids on. and that is it. Her face is swollen, and she complains that it hurts. Her mom doesn't plan on taking her to the dr until thursday. What are some repercussions that could happen.
