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.

    This bike is awesome! I'm everywhere on it! Just a few times it stopped working with all five bars (I think I restyled the battery), but after plugging it in for a cpl hrs with the five bars it worked like new. The battery last a cpl days of some hard riding... that's for sure!

    Great Purchase

    The bike was easy to assemble and had a retro look, I love it. After the battery charged for over 12hrs, my bike still wouldn’t power on. Retrospec customer service ordered me a new battery and it was delivered within 2 days. The bike rides smoothly, it’s easy to operate and the look of it turns heads. I have yet to use it to its full potential, but I’m excited to do so!
