Frequently Asked Questions (FAQs)

1. What size bike is best for 8 year old?

Most 8 and 9-year-olds will fit on a 20-inch wheel bike. Meanwhile, a 10-year-old (or older) will likely use the 24-inch size. Keep in mind that if your 10-year-old is smaller, they may still be more comfortable with a 20-inch bike wheel.
