What Size Bike Do I Need?

Choosing a bicycle that is the correct height is key to enjoying an efficient and comfortable ride. There are several methods of finding the bike size you need, but the easiest is to consult a size chart. These simple charts tell you how long the bike’s seat tube should be for your height.

While simple, a size chart is not the most accurate method. Many riders prefer calculating bike size according to their inside leg measurement.

To obtain your inseam measurement, stand upright in bare feet, and measure the distance between the ground and the spot where your leg joins your torso. Once you have your inseam measurement, you can look for a bike that fits you.

Pay attention to the bike’s stand-over height, the distance between the ground and the top tube. Ideally, your inseam will be at least two centimeters greater than the bike’s stand-over height.
