How to Size Your BMX Bike:
From motocross to stunts at the park, a BMX bike is built for action.
BMX bikes are lightweight yet sturdy, with compact wheels to handle maneuvers and tricks. While road and mountain bikes are sized by frame, your BMX bike is sized by the wheel.
At DICK'S Sporting Goods, BMX wheel sizes range from 16 to 20 inches. View the chart below, and use your height as a guideline to determine your wheel size:
