What's My Size?

Your inseam can help you find the perfect sized bike (measuring it properly is similar to pant inseams but measured a little differently). Here's how they work:

  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.

Looking to level up? Check out this upgrade.

Just what I was looking for

A simple steel frame fixie. Love it. I removed the rear brake but kept the front and I threw a mag wheel on the back, super happy with how it looks and rides. Thank you!
