How to measure my inseam for a bike

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.

    Less. Is. MORE!

    I was nervous about buying this bike with no reviews and was worried the price was too good to be true. I have to say, this bike has blown me away. It's fast, ultra lightweight, great looking, and you just feel the quality when your riding this thing. The thing that surprised me the most was how responsive and smooth the braking is.
