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.

  • Machined brake tracks

Review update

Review update : Bought the Harper in September and put 1800+ hard miles and counting and the bike has held up beautifully. The only issue I had was a rear tire blow out and that was because I ran over sharp debris. This is great bike especially for the price, I got another for my wife.
