Frequently Asked Questions
How do I know what size BMX bike I need?
BMX size is picked by wheel diameter and rider height, not age alone. Riders under 4 feet fit 12 to 18 inch wheels, and 20 inch suits adults.
What is the most common BMX bike size for adults?
Most teens and adults fit a 20 inch BMX bike, covering heights from 4'2 to 6 feet depending on top tube length. Taller riders often prefer cruisers.
Is a 24 or 26 inch BMX good for tall adults?
Yes. A 24, 26, or 29 inch cruiser BMX gives taller adults a longer frame and bigger wheels for a calmer ride than a standard 20 inch bike.
What size BMX bike should a kid start with?
Kids usually move from 12 or 14 inch wheels to 16 or 18 inch between ages 4 and 8, then graduate to a 20 inch BMX around 7.
How do I know if my BMX bike is too big?
A bike is too big if the rider cannot stand over the top tube with feet flat, or must stretch to reach the handlebars while seated on it.
