What size bike should an 11 year old have?

An 11-year-old typically needs a bike with a frame size between 24 to 26 inches, depending on their height and riding ability. A general guideline is that the child should be able to stand over the top tube of the bike with a few inches of clearance. It's essential to consider their comfort and control while riding, so adjustments to seat height and handlebar position are also important. Testing the bike for proper fit before purchasing is recommended.
