Sizing
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:
- 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.
A Rider Height
B Inseam
C Top Tube
| Size | Height Range | Standover Height |
| Frame: 18" | 34" |
