Measuring Inseam

Inseam is the most important metric to consider when deciding on bike size. In order to take this measurement properly, follow these guidelines:
  1. Stand upright with your feet 6-8" apart.
  2. Using a tape measure or tailor tape, measure from the bottom of your foot to the top of the inside of your leg.
  3. Compare your inseam measurement to the standover height of the bike. You should have about an inch of space between your body and the top tube.
