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.

Overall good bike. Arrived with rear tire not being true.

When I got this bike, there was a dent and rip in the cardboard. Luckily, there was no damage. It was easy to assemble, but the rear tire was not true, so now I have to do that myself or pay for it to be done at a store. The bike is fun to ride tho!

Made for a happy rider

This Orange-tire and gray frame Harper bike was purchased by me for an Uber deliveryperson who had the same Retrospec bike stolen He is overjoyed to be back on a very spiffy orange/gray. Be careful thieves like this bike. Your ordering process and fast delivery was superior Thanks you made a young rider happy!
