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:
- Stand upright with your feet 6-8" apart.
- Using a tape measure or tailor tape, measure from the bottom of your foot to the top of the inside of your leg.
- 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.

United StatesNice bike
I love the look of the bike, and I love how it is really sleek and almost feels like a road bike. I was a little disappointed because I ordered it online using your measurements guide and when it came it was too big for me. And you don’t have an exchange policy so I would of had to pay $45 more dollars to ship it back and get another one, so I just decided to keep it. I had to make some height adjustments to it, but it works.

United StatesToo Tall
Order a bike at least 2 sizes smaller than recommended. I ordered one a size smaller according to my height and I would be far more comfortable on one 1-2 sizes smaller. Overall, its a cool bike. Buy more reflectors!

United States4/5
I’m 5’7”, so based on the sizing chart, I ordered the recommended medium. It was too tall, and ended up fitting my 6’1” boyfriend perfectly. But the return process was smooth, and I’m waiting on my new one now. Unless you’ve got really long legs, I wouldn’t bet on the sizing chart. Other than that, the bike is great!
