How can you tell what size a bike is?

How to calculate a bike size? Measure your inseam!

  1. Stand close to a wall, your feet should be 6-8″ (15-20 cm) apart.
  2. Place a large, hardcover book between your legs – it will simulate the saddle.
  3. Mark where the book’s spine touches the wall.
  4. Measure the distance from that point to the floor – that’s your inseam.

Should you size up or down for bikes?

If you can reach them (or get close), you’re pretty flexible and might prefer a smaller size frame. If you find the riding position is a little bunched up you can extend it by replacing the stem. If you weren’t able to touch your toes (or even get close), then we recommend going for the larger size.

What does the size of a bike mean?
