To determine the best bike frame size for you, please take an accurate measurement of your inseam without shoes on. Then, using the chart below, find your inseam measurement in the column on the left. Refer to the corresponding row under Frame Size to determine the correct size frame for you.
If you do not know your inseam you can alternatively use your height to approximate the correct size of the bike that will best fit you. Use the right most columns to find your height and refer to the third column for the appropriate frame size that matches your height range.
Bikes sizes range from 15 inches to 23 inches and are available in two inch increments. If your inseam is greater than 35.4 inches or you are taller than 6 feet 3 inches you will want to select a 23 inch frame.
