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.
SizeHeight RangeStandover Height
43CM - XS 5’5” - 5’7” 29.5"
49CM - S 5’8” - 5’10” 31"
53CM - M 5’11” - 6’0" 32.25"
57CM - L 6’1” - 6’2” 33.375"
60CM - XL 6’3” - 6’5" 35"

    Pleasantly pleased

    Besides getting used to the coaster brake, I love it! I did make some changes to add a personal touch.

    Nice bike

    It’s a cool bike. It’s stripped down in a nice way!

    I added a front hand brake.
