Kids and youth BMX bikes. What size BMX do i need for my child?
When selecting a BMX bike for kids, it's usually safer to choose a bike that's properly sized or slightly smaller. This gives them better control compared to a bike that's too large, which can leave them overstretched. If your child is a confident rider and growing quickly, you might consider going for a larger size. Ultimately, this is just a general guideline—you're the best judge of your child's abilities!
